OPERATION
BEFORE OPERATION CHECKLIST
In short Before each use, check the machine's condition and fix any problem you find, or have your service dealer correct it. The machine must be on a level surface with the engine switch OFF and the propane tank valve CLOSED while you go through the checklist.ββββ ββββββββ β ββββββ β ββββββββββββββ ββββββ βββββ ββββββββ β β βββ ββ
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.ββββ ββββββββ β ββββββ β ββββββββββββββ ββββββ βββββ ββββββββ β β βββ ββ
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.
WARNING! Avoid use in areas with floor obstruction such as thresholds and floor outlet boxes. Avoid use in areas with loose debris or small objects that may become caught in the rotating pad.
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 all SAFETY INSTRUCTIONS on pgs 3-9.
B. CHECK THE GENERAL CONDITION OF THE MACHINE
Look around and underneath the machine and engine for signs of oil leaks.
Remove any excessive dirt or debris, especially around the muffler and recoil starter.
Look for signs of damage.
Check that all shields and covers are in place, and all nuts, bolts and screws are tightened.
Address all of the above issues before proceeding.
C. CHECK THE ENGINE
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.
Check the air filter element (see pg 32). A dirty air filter element will restrict air flow to the carburetor, reducing engine performance.
D. CHECK THE MAINTENANCE SCHEDULE
Review the maintenance log that must be kept with the machine. Perform any maintenance necessary before proceeding. 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 19).

PRE-OPERATION CHECKS
E. CHECK THE ENGINE OIL
In short Check the engine oil with the machine level, taking two dipstick readings before adding any oil. Add only enough to reach the full mark.ββββ ββββββββ β ββββββ β ββββββββ ββββββ ββββββ ββ β βββββ β ββ βββββββββ
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.ββββ ββββββββ β ββββββ β ββββββββ ββββββ ββββββ ββ β βββββ β ββ βββββββββ
F. CHECK THE PROPANE/LPG TANK AND LINES
In short Soap test the LPG tank and lines for leaks every time a tank is filled or connected, and never overfill the tank. Connect the high pressure hose hand tight, without a tool.
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.
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 GENERAL OPERATION SAFETY INFORMATION on pgs 3-9. In some cases, the regulator must defrost before restarting the engine.
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 GENERAL OPERATION SAFETY INFORMATION on pgs 3-9.
G. INSTALL FRESH PADS OR BRUSHES
In short Turn off the engine and propane before tilting the machine back. To change a pad, remove the pad-centering ring, swap the pad, and reinstall the ring.
Never tilt back machine while engine is running. Turn off engine and shut off propane tank. Do not tilt machine on its side; damage can occur to the machine, furniture, buildings and/or personal injury. Machine should only be tipped back to transport or for service, if properly turned OFF, in a safe environment and positioned on a flat surface.
To install a fresh pad, lean the machine back and safely secure. Unscrew and remove the pad-centering ring. Remove the old pad and center the new pad onto the pad driver. Reinstall the pad-centering ring. Never βflipβ a pad.
Keep the pad with 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.

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.

TROUBLESHOOTING
TROUBLESHOOTING - ELECTRICAL SYSTEM
In short This section covers checking the electrical system when the machine has a problem. Inspect wire connections and battery posts, prepare a good propane tank and a 12-volt power source before deeper troubleshooting, and disconnect the starter to check the control equipment without spinning the engine.ββββ ββββββββ β ββββββ β ββββββββββββββ ββββββββββ ββ β ββββ βββ ββββββ
WARNING Always wear a face shield, safety goggles 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 βlooseβ, 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.
