Grounding instructions
This machine must be grounded. If it should electrically malfunction, grounding provides a path of least resistance for electrical current to reduce the risk of electrical shock. This machine is equipped with a cord having an equipment-grounding conductor and grounding plug. The plug must be plugged into an appropriate outlet that is properly installed in accordance with all local codes and ordinances.
This machine is for use on a nominal 120-volt circuit and has a grounding attachment plug that looks like the plug illustrated below. Make sure that the machine is connected to an outlet having the same configuration as the plug. No adapter should be used with this machine.

Machine setup
Installing brush
- Raise the scrub head to the transport position by stepping on the scrub head lift pedal (Figure 1).
- Remove the brush idler plate from the brush base. Turn the idler plate locking knob counter-clockwise to remove (Figure 2).
- Connect the slotted end of the brush to the drive hub (Figure 3).
- Connect the idler plate to the brush and reinstall the idler plate. Make sure the idler plate hooks engage the brush base and that the locking knob is secure (Figure 4).
NOTE: If storing the machine for an extended period, raise the scrub head to the transport position (Fig. 19).
Filling solution tank
- Lift the cover and remove the solution tank from the machine (Figure 5).
- Fill the solution tank with 3 gal (11 L) of clean water (122°F (50°C) maximum temperature) (Figure 6). Do not fill beyond the “MAX” fill label. Partially fill if unable to lift a full tank.
- Pour an approved low foaming cleaning detergent into the solution tank according to the mixing instructions on the bottle.
Contact your dealer for recommended cleaning detergents.
- Submerge the solution hose screen into the solution tank and close the cover (Figure 7).
Connecting power cord
- Plug the supplied power cord into the machine and attach the power cord to the strain relief clip as shown (Figure 8).
- Plug the power cord into a properly grounded wall outlet (Figure 9).
- Wrap the power cord around the handle and cord hook when storing machine. To remove power cord, turn the cord hook upward (Figure 10).
Machine operation
Pre-operation
- Inspect power cord for damage.
- Sweep and dust-mop the floor.
- Check that the brush and squeegee blades are installed.
Scrubbing floors
- Pull the handle adjustment lever and adjust the handle to a comfortable operating height (Figure 11). Release the lever to lock the position.
- Lower the scrub head to the floor by stepping on the transport release pedal (Figure 12).
- Press the main power switch to the on ( I ) position (Figure 13).
- Press the scrubbing mode switch towards the vacuum/brush/solution mode (Figure 14).
- To begin scrubbing, pull the start triggers and push or pull the machine in either direction (Figure 15).
- When stopping, release the triggers and continue to move the machine to pick up all solution.
- View the water pickup from the recovery window (Figure 16). When the water pickup stops, unplug the power cord and empty the recovery tank.
The machine is equipped with a vacuum shut-off float that will automatically stop the water pickup should the water level reach the full point. A sudden change in vacuum motor sound will occur.
- For heavily soiled areas, press the scrubbing mode switch towards the brush/solution mode (Figure 17). This allows you to use the double scrub method. First scrub the soiled area in the brush/solution mode then scrub the area a second time in the vacuum/brush/solution mode.
- The brush circuit breaker will trip if the brush is obstructed. To reset the circuit breaker, unplug the power cord, remove the obstruction and reset the 5 amp circuit breaker button (Figure 18). If the circuit breaker does not reset immediately, allow the motor to cool.
- When transporting machine, raise the scrub head to the transport position (Figure 19).
Machine maintenance
To keep the machine in good working condition, simply follow the machine’s maintenance procedures.
After each use
- Wipe clean the power cord and inspect it for damage (Figure 20). Wrap power cord around handle and cord hook when not in use (Figure 21).
- Empty the recovery and solution tanks and thoroughly rinse with clean water (Figure 22).
- Clean the vacuum shut-off float (Figure 23) and the vacuum intake screen of any debris buildup (Figure 24).
- Clean the solution hose screen (Figure 25).
- Remove and clean the brush (Figure 26). Replace brush if worn.
- Clean the underside of the scrub head (Figure 27).
- Clean the squeegee blades of any debris (Figure 28). Replace the blades if worn or damaged.
To remove the squeegee blades, lift the blade retainer clip and pull the blade from the channel (Figure 29).
When replacing blades, install the red blades to the inside channels and the gray blades to the outside channels, ribs facing outwards.
NOTE: The red and gray blade rails are designed to match up with the appropriate channel to prevent improper blade installation.
- Clean the machine with an all purpose cleaner and damp cloth (Figure 30).
After every 100 hours of use
- Flush the solution system with white vinegar to remove any chemical deposits. Pour 1/2 gal (2.2 L) of white vinegar into the solution tank and operate the machine for 1-2 minutes, then let vinegar sit for up to six hours. Rinse solution system with water.
- Remove the spray tip and soak in white vinegar to prevent clogging. Do not use a pointed object to clean out spray tip, damage will occur (Figure 31).
