GENERAL OPERATION SAFETY INFORMATION

In short LPG (propane) is stored under pressure and must be handled properly. The messages below cover carbon monoxide symptoms, ignition sources, gas leaks, the propane control equipment and venting an overfilled older tank.

Liquefied petroleum gas (LPG or propane) is stored under pressure and must be handled in the proper manner to be safe. Observe the following safety messages to get the best performance, lowest emissions, and longest life out of your equipment.

NOTICE The EPA has rated the PurePowerLPG™ 600 Series engine cleanest in the industry for CO (carbon monoxide) emissions. (Source: https://www3.epa.gov/otaq/certdata.htm#smallsi).
DANGER Because CO is always a byproduct of internal combustion engines, it is important to know the symptoms of CO exposure, which may include drowsiness, dizziness, nausea, vomiting, confusion, collapse, loss of consciousness and muscle weakness. If such symptoms occur during operation with this machine, immediately shut off the machine and go outside for fresh air. Have a qualified service technician test the machine for CO emissions before using again. Call for emergency medical attention and DO NOT operate this machine or other propane powered equipment until cleared by a physician. For more info on CO exposure effects, see http://www.mayoclinic.org/diseases-conditions/carbon-monoxide/basics/symptoms/con-20025444.
DANGER No smoking, no sparks, no flames near machine, engine or LPG tank. Do not operate this machine in an environment with a potential ignition source.
DANGER If you smell gas: immediately stop the unit, check for leaks, open windows, don’t touch electrical switches, extinguish any open flames, and contact a repair professional.
DANGER Never change or alter the propane control equipment. It is precisely tuned to power machinery with minimal levels of carbon monoxide. Altering the control equipment could cause dangerous levels of engine emissions.
DANGER Effective January 1, 2016, all Aztec Products, Inc. machinery is shipped with propane tank equipped with Overfill Protection Device (OPD). If you have an older LPG cylinder that is overfilled, always vent outdoors, away from closed areas where gas may accumulate, and away from any fire, flame, or spark-producing device. Use a screwdriver to vent excess propane, which escapes as a white mist. Propane will vent clear when correct tank level has been achieved.

SAFETY
NOTICE An abbreviated, quick reference schedule of the manufacturer’s suggested maintenance is on the underside of the handle. This abbreviated schedule is for quick reference only and is not intended to replace the full maintenance schedule in the Owner’s Manual.
NOTICE A maintenance record must be kept, indicating all dates of service, hours on engine at time of service, and service performed in order to maintain manufacturer’s warranty coverage. Perfect record keeping does not guarantee warranty coverage if the damage to the machine is non-warrantable. See warranty coverage policy details at the end of this Owner’s Manual. The maintenance record must be kept with the machine and transferred to the new owner if resold.
NOTICE Using the electric starter for more than 5 seconds at a time will overheat the starter motor and can damage it.
NOTICE A “NO SMOKING” sign should be permanently displayed at the storage area.
NOTICE Do not remove machine/engine labels and/or WARNING stickers on machine or engine. If any labels or stickers come lose, contact Aztec ([email protected]) for replacement.
NOTICE Your new propane powered machine includes a new, empty, vertical LPG propane tank with OPD (Overfill Prevention Device). This is a safety shutoff device incorporated into the filling valve of the propane tank. The OPD valve is designed to prevent cylinder overfilling in excess of the cylinder's maximum permitted filling limit. This valve is provided by the LPG tank manufacturer and may malfunction. The OPD is not to be relied upon in filling the LPG tank; the propane tank is to be filled by weight or by use of a fixed liquid level gauge. The OPD is a backup safety device only.
NOTICE Your new machine has a Carbon Monoxide (CO) detection badge; please keep in mind the following important notes about this CO sensor:
  • Once opened, the CO detection badge will expire in 90 days, so write the open date on the badge when installing on your machine.
  • The CO detection badge is individually wrapped and must be unwrapped for detector to function.
  • To apply, simply unwrap the badge, remove the orange backing and apply to the handle assembly of your propane machine, somewhere easily visible to the operator.
  • The CO detection badge is a passive carbon monoxide detector and can detect as little as 100 parts per million (ppm) carbon monoxide gas at an approximate relative humidity range of 33 to 50%. If the humidity is very high it can detect concentrations as low as 20ppm.
  • If CO is present in the area, the circle indicator will change color (from orange-red to red-brown, and then to gray-black as the concentration levels increase).
  • Once the CO detection badge is exposed to fresh air it will return back to orange-red and may be reused.
  • There is no alarm function and requires no power, but must be visible and seen to determine whether CO is present in the area.
  • The CO detection badge will be inactivated and damaged by the presence of halogens (iodine, chlorine, bromine), and ammoniac or nitrous gases.

BEFORE OPERATION CHECKLIST

BEFORE OPERATION CHECKLIST

In short Before each use, check the machine and engine for condition and problems, with the machine on a level surface, engine switch OFF and propane tank valve CLOSED. The checklist covers safety messages, general condition, engine oil and air filter, the maintenance meter and the engine oil level.‌‌​⁠‍​‌⁠⁠‌⁠‍​‍‍‌​‌‌⁠​​​​​​‍‍​​​‌​⁠​​​​​⁠​‌⁠‍‍‌‍​⁠​‍‌‌⁠​⁠‍⁠​‍

For your safety, to ensure compliance with environmental regulations, and to maximize the service life of your equipment, it is very important to take a few minutes before you operate this machine to check its condition. Be sure to take care of any problem you find, or have your service dealer correct it before you operate this machine.‌‌​⁠‍​‌⁠⁠‌⁠‍​‍‍‌​‌‌⁠​​​​​​‍‍​​​‌​⁠​​​​​⁠​‌⁠‍‍‌‍​⁠​‍‌‌⁠​⁠‍⁠​‍

WARNING Improperly maintaining this machine and its engine, or failure to correct a problem before operation, may cause a malfunction in which you can be seriously hurt or killed. Always perform a pre-operation inspection before each use, and correct any problem.

Before beginning your pre-operation checklist, the machine and engine must be on a level surface, with the engine switch in the OFF position, and the propane tank valve is in the CLOSED position. Always check the following items before you start the engine:

A. READ AND UNDERSTAND ALL SAFETY MESSAGES:

Carefully read and understand the SAFETY INSTRUCTIONS on pages 3-9.

B. CHECK THE GENERAL CONDITION OF THE MACHINE:

  1. Look around and underneath the machine and engine for signs of oil leaks.
  2. Remove any excessive dirt or debris, especially around the muffler and recoil starter.
  3. Look for signs of damage.
  4. Check that all shields and covers are in place, and all nuts, bolts and screws are tightened.

C. CHECK THE ENGINE:

  1. Check the engine oil level and filters. Running the engine with a low oil level can cause engine damage. Your first oil change should be after the first 8 hours of use.
  2. Check the air filter element. A dirty air filter element will restrict air flow to the carburetor, reducing engine performance.

D. CHECK THE MAINTENANCE SCHEDULE

All machines are equipped with a multi-function maintenance meter. The functions include the following: hour meter, service alert and tachometer. (See ENGINE MAINTENANCE METER instructions on pg 14).

E. CHECK THE ENGINE OIL

Make sure the machine is level when checking the oil. Always take two (2) readings of the dipstick before adding oil. If the oil level is below the full mark, add just enough oil to the engine to bring the oil level up to the full mark. Never over fill. Check for foreign material on the dipstick.

PRE-OPERATION CHECKLIST

F. CHECK THE PROPANE/LPG TANK AND LINES:

In short Before running the machine, soap test the LPG tank and every line and connection for leaks, and never overfill the tank. Connect the high pressure hose to the tank hand tight only, then return the machine to its upright operating position.‌‌​⁠‍​‌⁠⁠‌⁠‍​‍‍‌​‌‌⁠​​​​​​‍⁠​​​‌​⁠​​‌‌‌‍‌​⁠‍‍‍‌​​​​‌‍‍​‌​‍​​
  1. Every tank has been pressure and leak tested. However, every time a tank is filled and/or connected to the machine it should be soap tested. All LPG lines must be pressurized and every inch of line and connections must be sprayed. If you find a leak, make the proper repairs before operating the machine.
  2. Never overfill the LPG tank. The LPG tank is designed to hold a maximum of 20 pounds of propane. Make sure to weigh the tank as it is being filled. The gross weight of a full tank should not exceed 48 pounds. If, while operating the machine, you notice frost forming on the LPG lines or the regulator, your tank has been over filled. If you continue to operate the machine in this condition, damage will occur. The excess propane in the tank must be removed before normal operations resume. The bleeding of a propane tank must be done in a safe manner; refer to the SAFETY INFORMATION on pgs 3-9. In some cases, the regulator must defrost before restarting the engine.
  3. To connect the high pressure hose to the LPG tank, make sure the couplers are in line and screwed together, hand tight. If this is not done properly, fuel will not pass through to the regulator. Never complete the connection of the tanks to the machine by using a tool; refer to the SAFETY INFORMATION on pgs 3-9.

G.

Once this checklist is complete, restore the machine to an upright, operating position. Then fill water tank before operation if using in wet operation.‌‌​⁠‍​‌⁠⁠‌⁠‍​‍‍‌​‌‌⁠​​​​​​‍⁠​​​‌​⁠​​‌‌‌‍‌​⁠‍‍‍‌​​​​‌‍‍​‌​‍​​

MAINTENANCE

ENGINE MAINTENANCE METER

In short The engine maintenance meter is a tool that shows run hours and engine RPM and flashes when the oil needs service. After servicing, reset it with the reset button on the meter face.‌‌​⁠‍​‌⁠⁠‌⁠‍​‍‍‌​‌‌⁠​​​​​​⁠‍​​​‌​⁠​​​‍‌​‌‍‌⁠​‌‍⁠‍⁠​⁠​‌‍⁠‌‍‌‌

This multi-function meter acts as a preventive maintenance tool, which benefits you with increased fuel economy, less down-time and longer engine life.‌‌​⁠‍​‌⁠⁠‌⁠‍​‍‍‌​‌‌⁠​​​​​​⁠‍​​​‌​⁠​​​‍‌​‌‍‌⁠​‌‍⁠‍⁠​⁠​‌‍⁠‌‍‌‌

The meter displays are:

  • Hour Meter: Displays total run hours when machine is off.
  • Tachometer: Indicates engine RPM during operation.
  • Service Alert: The display flashes to alert you to lube and change the oil at 25 hour intervals. After the service is complete, the meter can be reset by pushing the reset button on the face of the meter. Therefore, it is recommended that a separate maintenance log be kept to track of oil changes.

TRANSPORTING THE MACHINE

In short Before transporting, put the machine on a level surface with the engine switch OFF and the propane valve CLOSED, then tilt it back and fit the transport wheel. Secure the machine in the vehicle so it cannot move, and pull it back rather than push it when loading up a ramp.
CAUTION The Refresher must be secured on a level surface when transporting in a vehicle. Once the machine is loaded into the transport vehicle, remove and store the Transport Wheel on the top deck of the machine. Secure the machine in the vehicle so it cannot move or bounce during transporting; damage may occur to the machine and/or the vehicle and surrounding objects.

First, refer to the SAFETY INFORMATION on pages 3-9. The machine must be on a level surface, with the engine switch in the OFF position, and the propane tank valve in the CLOSED position.

Remove the propane tank from the machine, or disconnect the connection and securely fasten tank to machine. Adjust handle of machine to comfortable position to tilt back; secure handle in place with pin provided.

To tilt back the machine, place one foot on the propane tank base bar, one hand on the handle base, and one hand on the “T” handle. Pull back and down from the handle base, and push down with your foot, using the “T” handle only to control lateral motion.

Once secured in a tilted back position, insert transport wheel and secure with pin provided. Push machine forward, to desired location, unless loading machine up on a ramp into a vehicle. When loading up a ramp into a vehicle, the machine should be pulled back rather than pushed forward, to prevent tipping over.

INSTALLING PAD DRIVERS, DIAMOND DRIVERS, STRIP BRUSHES

In short Install fresh pads, brushes, resins or hybrids before every job. Leave the tape on strip brushes, and tilt the machine back and secure it before removing drivers or brushes.

First, refer to the SAFETY INFORMATION on pages 3-9. Install fresh pads/brushes/resins/hybrids before every job.

CAUTION Do not remove tape from strip brushes. Removing the tape from the strip brush reduces the brush life and effectiveness.

To remove pad drivers, diamond drivers or strip brushes, tilt machine back and secure in place. To tilt back the machine safely, refer to TRANSPORTING THE MACHINE above. To remove Velcro® diamond pucks, pull apart from inside edge of drive pad, NOT from outside edge.

OPERATION
NOTICE Do not pull Velcro® diamond pucks from outside edge of drive plate, to avoid damage to adhesive surface on the outer surface. Remove only from the center out, towards the outer edge.
NOTICE Dispose of used pads, brushes, hybrids and diamonds responsibly.
Once the machine is secured in the tilted back position, rotate the drivers approximately 1/8 turn clockwise to release from the spring clip, and remove.

To install pad drivers, diamond drivers or strip brushes, align the three lugs on top of the driver with the holes on the drive plate; rotate driver counter-clockwise until driver clicks and locks into spring clip securely.‌‌​⁠‍​‌⁠⁠‌⁠‍​‍‍‌​‌‌⁠​​​​​​⁠⁠​​​‌​⁠​​​‍‍‍⁠‌‍‌‍​‍​​‌⁠⁠⁠‍​‌‌​‍‌

Remove old pads and center the new pads onto each pad driver, one at a time.

NOTICE Never “flip” a pad. Keep the same side down throughout the life of the pad. Even after a pad is cleaned, you can tell the down side by the centering ring indentation. This practice will increase the pad life and help maintain a properly functioning pad driver.

MACHINE CLEAN UP

In short The machine must be cleaned after each use, once the job is complete for the day/night, or the manufacturer's and engine warranty will be voided. Close the propane valve, turn the key off, empty the water tank, check for loose hardware and rinse the machine, avoiding the brush drive.‌‌​⁠‍​‌⁠⁠‌⁠‍​‍‍‌​‌‌⁠​​​​​​⁠⁠​​​‌​⁠​​​‍‍‍⁠‌‍‌‍​‍​​‌⁠⁠⁠‍​‌‌​‍‌

Refer to the SAFETY INFORMATION on pages 3-9. Once the job is complete for the day/night, clean up is required. The manufacturer’s and engine warranty will be voided if the equipment is not properly maintained. Clean the entire machine after each use:

  1. Turn the propane tank valve clockwise to CLOSED position and turn the engine key to OFF position.
  2. Empty excess water from water tank.
  3. Refer to TRANSPORTING THE MACHINE on page 14 to properly tilt back and secure machine.
  4. Check the machine for possible loose nuts and bolts; tighten and secure as needed.

TROUBLESHOOTING

STORING THE MACHINE AND PROPANE TANKS

In short At the end of each job, take the propane tank off the machine and store it in a well ventilated approved area. Keep the machine in a safe and secure area.‌‌​⁠‍​‌⁠⁠‌⁠‍​‍‍‌​‌‌⁠​​​​​‌​​​​​‌​⁠​​‌‍​​‌​​‍⁠‌⁠‌​​‍⁠​‌‌​⁠​⁠⁠

Once the job is complete for the day/night, remove the propane tank from the machine and store the tank in a well ventilated approved area. Store your machine in a safe and secure area. Refer to the SAFETY INFORMATION on pages 3-9.‌‌​⁠‍​‌⁠⁠‌⁠‍​‍‍‌​‌‌⁠​​​​​‌​​​​​‌​⁠​​‌‍​​‌​​‍⁠‌⁠‌​​‍⁠​‌‌​⁠​⁠⁠

TROUBLESHOOTING THE ELECTRICAL SYSTEM

In short Use this section to find electrical faults. Check wire connections and battery posts, make sure a good 12 volt source is available, and disconnect the starter if the fault seems to be in the control equipment.
WARNING Always wear a face shield, safety glasses and protective clothing when working around a battery. The gases can be explosive and the acid is highly corrosive to metals, cloth and ALL HUMAN TISSUE (skin, eyes, etc.).
NOTICE Safety first. Contact an authorized service center as needed.
  • Check all wire connections for obvious problems. Remove propane tank, then remove battery box cover. Check all connections visibly and physically. If any “loose”, damaged or unconnected wires are noticed, replace or repair as needed.
  • Check the battery posts and wires. If the battery post(s) are corroded, remove the wires and clean posts and wires. Applying some axle grease on the posts of the battery after they are cleaned will slow down the battery corrosion process. If nothing obvious is noted, a more detailed investigation is warranted. Before any such troubleshooting begins, the following things should be done:
    • Replace propane tank with one from a machine that runs.
    • Charge the battery or provide an absolute source of 12 volt DC power capable of 50 amperes total output. Jumper cables from a car or truck battery will suffice. Use a 12-volt test light.
  • If the problem appears to be in the electrical control equipment, disconnect the starter from the system so as to check the system without spinning the engine.
  • Battery rundown is a common problem. An engine key left in the ON position when engine is turned OFF will result in battery running down.

TROUBLESHOOTING

TROUBLESHOOTING MAIN DRIVE BELT

In short Use this section when the engine runs but the drive unit will not engage, which usually points to the main drive brush belt or the belt tension spring. The steps cover checking the belt cover, refitting or replacing the engine drive belts, and changing the brush drive belt.‌‌​⁠‍​‌⁠⁠‌⁠‍​‍‍‌​‌‌⁠​​​​​‌​‌​​​‌​⁠​​‌​​⁠‌‍‌‌​‍​​⁠‍‌‍​‌⁠​‍⁠⁠​
NOTICE Safety first. Contact an authorized service center as needed.

If the engine runs but the drive unit will not engage, this is usually related to the main drive brush belt or belt tension spring. Without removing the drive unit you can check and fix the following:‌‌​⁠‍​‌⁠⁠‌⁠‍​‍‍‌​‌‌⁠​​​​​‌​‌​​​‌​⁠​​‌​​⁠‌‍‌‌​‍​​⁠‍‌‍​‌⁠​‍⁠⁠​

  1. Remove the four 3/8" bolts holding the belt cover to the body. Remove the (1) 3/8" bolt holding the muffler bracket to the belt cover. Check if belt tension spring is attached to the idler spring mount bolt on the body.
  2. Check to see if belts have come off of input pulley or centrifugal clutch. If so, install belts back on the pulley. Note: If belts come off again they are probably worn or stretched and need replacement.
  3. To replace engine drive belts:
    1. Loosen the (3) bolts on the right hand side of the upper deck approximately 4 to 5 turns. Be sure at least half of the bolt threads remain engaged. Place machine in the tilt-back position. Remove old or worn belts and replace them with the new ones.
    2. Remove one end of the tension spring to aid in installation of new belts. Check for wear on the springs and their catches.
  4. Re-attach tension spring to mount bolt and tighten (3) 1/2" bolts. Slide the belt cover into place and start (4) 3/8" bolts into belt cover (hand tighten only). Start (1) 3/8" bolt into muffler bracket and belt cover, then tighten all (5) 3/8" bolts.
  5. To change the brush drive belt: Remove three (3) bolts on the right hand side of upper deck (use a 3/4" wrench). Slowly raise front of machine off the floor. Remove Input Boom Pulley and Boom Arm from Brush Drive by using the two 3/4" wrenches—sliding them into the slots in the boom pulley shaft to unscrew the pulley from the shaft. Remove six (6) bolts from bottom side of Brush Drive and split Brush Drive Top Pan and Brush Drive Plate. Remove worn belt and replace. It is a good idea at this time to check the Tension Spring, bearings and idler for damage and replace them if necessary.

ELECTRICAL SCHEMATIC

ELECTRICAL SCHEMATIC

In short This page shows the wiring diagram for the machine's 12 volt battery, key switch, starter solenoid, voltage regulator, starter, fuel lock off, oil switch and hour meter. It also gives the wire color legend and refers to the Kawasaki owners manual for the ignition and charging circuit.‌‌​⁠‍​‌⁠⁠‌⁠‍​‍‍‌​‌‌⁠​​​​​‍‍⁠​​​‌​⁠​​⁠‍‍​​‌‍‌‌​​​‍‍‍​‌​‍‌​⁠​‌

Batteries and chargers: make sure your charger is compatible with your batteries, and set its charging algorithm to your battery pack before you use it.

Electrical schematic of the machine. A 12 volt battery feeds the starter solenoid with red wires. The key switch, shown looking into the wire side of the switch connector, connects to the solenoid by red and green wires. A blue wire in the wiring harness runs to the fuel lock off, which connects by a black wire to the oil switch and to ground. The starter solenoid also connects to the voltage regulator and to the starter, which is grounded. A separate hour meter has a black wire that wraps around the spark plug lead.

Aztec Products, Inc. warrants its products to be free from defects in material and workmanship for a period of one year from the date of sale. All engines are warranted by the manufacturer for a period of two years when engine maintenance schedules are followed.

The warranty does not apply to damage or failure caused by abuse, misuse, neglect, disassembly, alteration, unauthorized modification or repair, lack of proper maintenance, theft or damage by freight carriers. The warranty applies to parts, labor, and ground freight only. Aztec is not liable for transportation to or from repair centers or travel for on-site repairs. Aztec Products, Inc. will not be liable for incidental or consequential damages arising from the use of any of its products, whether defective or not.

Aztec Products, Inc. agrees, at its discretion, to repair or replace at its own expense any product or part(s) which examination proves to be defective in workmanship or materials provided that the purchaser notifies Aztec Products, Inc. directly within the warranty period and follows the Return Goods Policy.

In order to obtain parts warranty, the following procedures must be followed:

  1. Customer must call Aztec Products, Inc. for an RGA (Return Goods Authorization) Number.
  2. Aztec maintains the serial number, date of shipment or sale, and customer name on each piece of equipment sold. If you were the purchaser, please reference that information on your request for replacement or repair. If you purchased the equipment through a distributor, please contact them first. If you are not satisfied, contact Aztec and give us the distributor name, purchase date, and the serial number of the product.
