IMPORTANT SAFETY INSTRUCTIONS
CAUTION
Operators must read and understand this manual before operating or maintaining this
equipment.
• Do not operate this scrubber in the red discharge area of the battery condition meter.
Operating the scrubber for long periods in the red zone of the gauge will cause overheating
of the motors and possible permanent damage to the batteries may result. If you are using
the machine and thebattery indicator needle does go into the red, finish the area you are
working in and then recharge the batteries immediately.
• Keep hands and feet clear of moving parts while machine is in operation.
• All switches must be in the “OFF” position when charging batteries.
• Electrical motors and components can cause an explosion when operated near explosive
materials or vapors. Do not operate this machine nearflammable materials such as solvents,
thinners, fuels, grain dusts, etc.
• Make sure all switches are turned “OFF” and battery connections are removed before
performing any maintenance procedures.
• Store or park this machine on a level surface only.
• These machines are designed for level floor operation only. DO NOT OPERATE on ramps or
inclines.
• Battery acid can cause burns. When working on or around batteries, wear protective clothing
and safety glasses. Remove metal jewelry. Do not lay tools or metal objects on top of
batteries.
• This machine is not suitable for picking up hazardous dust.
Charging batteries generates explosive gases. DO NOT CHARGE BATTERIES WHEN OPEN
FLAMES OR SPARKS ARE PRESENT. DO NOT SMOKE. Make sure the charger is turned off
before disconnecting it from the batteries. Charge the batteries in a well-ventilated area.
Maintenance and repairs must be performed by authorized personnel.

BATTERY INSTALLATION:
1. Disconnect tank drain hose from rear of machine.
2. Disconnect vacuum recovery hose.
3. Raise tank assembly by gripping side hand holds, and tilting forward.
4. Position tank kickstand as shown below, figure 1, to hold tank in upright position. To lower,
raise tank slightly forward and manually move kickstand to freed position.
5. Install batteries as shown in figure 2.
CHARGING OF BATTERIES:
Charging of batteries generates explosive gases. DO NOT CHARGE BATTERIES WHEN

turned off before disconnecting it from the batteries. Charge the batteries in a well-ventilated
area. Fluid levels should be checked before and after charging and maintained at the proper
levels.

OPERATING INSTRUCTIONS
1. Filling: Fill the solution tank with the desired amount of water and add liquid cleaning solution
to the proper dilution ratio. DO NOT USE powdered cleaning chemicals. Powders are unlikely
to dissolve thoroughly, resulting in clogging the in-line solution filter. This can reduce or stop
water flow to the brush.
2. Close lid.
3. Lower brush assembly.
- To lower the brush, first push the pedal slightly towards the center of the
machine (unlock it), then release it slowly.
- To lift the brush, press the pedal down until lift mechanism engages.
4. Turn on brush switch.
5. Adjust solution control feed lever.
6. Turn on vacuum switch.
7. Lower Squeegee assembly.
After Use:
1. Turn off solution feed.
2. Switch off brush and raise.
3. Raise Squeegee assembly.
4. Turn off vacuum motor.
Solution and recovery tanks should be emptied after every use.
MAINTENANCE:
Daily 1. Clean float assembly & Squeegee blades. Vac filter.
2. Recharge batteries (check battery acid levels before and after
charging).
Monthly 1. Check wear on Squeegee blades.
2. Grease rear wheels.
3. Grease pivot points on brush motor assembly.
Every 500 hours check condition of carbon brushes on vacuum motor and brush
drive motor.
