TO ASSEMBLE
This electric scrubber is completely assembled. Just attach the stan-
dard pad drive brush and the appropriate pad or a model 20 scrub
brush. The scrubber is ready to operate.
TO ATTACH BRUSH
Tilt the machine back until the safety stands located on each side of
the front opening may be released to support scrubber. Select the
desired brush, scrub or drive, and position the three slots of the clutch
plate over the three lugs of the drive plate. Turn the brush counter-
clockwise as far as it will go. The brush is now seated in ready-to-use
position.
TO REMOVE BRUSH, disengage clutch plate slots from drive plate lugs
by turning clockwise.
DO NOT OPERATE THE SCRUBBER WITH SCRUB BRUSH OR DRIVE
BRUSH AND PAD IN PLACE.
TO OPERATE
With the "brush drive" switch turned to ON, lift the solution tank locat-
ed at the front of the scrubber and rest on the chassis. Partially fill the
solution tank. Locate the metering valve positioned just above the
solution solenoid. Turn the "solution control" switch to ON and adjust
the metering valve for desired flow. Turn off all switches, replace solu-
tion tanks and fill. DEFOAMER MUST BE ADDED TO THE RECOVERY
TANK BEFORE OPERATING THE SCRUBBER.
This scrubber is designed to scrub and vac-squeegee dry in a single
operation. With the "brush drive" switch turned to ON, turn the "solu-
tion control" switch to ON for continuous flow or turn ON and OFF to
regulate intermittent flow. Turn the "vac" switch to ON. Lower the
brush by depressing the brush foot pedal and moving the pedal left into
the longer of the slots. Lower the squeegee to vacuum position by

pushing the squeegee knob to the right. Push the scrubber at a slow,
but steady pace for best results. Double scrubbing may be necessary
if infrequent cleaning causes heavy soil build up. In this situation make
a scrubbing pass with solution and brush only with the squeegee in UP
position. Then rescrub the area with the squeegee in normal DOWN
position for water pick-up.
Clean small areas at a time when double-scrubbing.
To raise the brush, depress the brush foot pedal, then move right into
the shorter of the slots. The squeegee is raised by moving the
squeegee knob to the left.
TO STOP:
Turn "solution control" switch to OFF approximately (10) feet before
anticipated stopping point. Raise brush and turn "brush drive" switch
to OFF. Maintain "vac" switch at ON and squeegee in down position
until all solution has been picked up. Run vacuum motor approxi-
mately (30) seconds after all solution has been picked up which allows
hose to clear.
CARE AND MAINTENANCE:
SOLUTION AND RECOVERY TANKS
These tanks are a low maintenance polyethylene material, however,
periodic brush cleaning and rinsing is necessary to prevent dirt and
sediment build-up. Do not allow unused solution or dirty water to
remain in tanks.
Eventually solids build-up and will clog feed line and drains. After
using, flush lines with clean water.
SQUEEGEE BLADES
Replace worn rubber blades. To install new blades remove screws and
retaining strips, install blades, then reassemble squeegee.
Corrective Action
1. Replace fuse or reset circuit breaker
2. Replace switch
3 Replace power cord
1. If voltage under recommended minimum, check size of wiring
from main switch; if okay, contact power company
1. Return to service center
2. Return to service center
1. Remove cylindrical screen from brass fastener in solution feed line
and clean
2. Check to see if closed or clogged
3. Check solenoid or line clog
1. Replace blades
2. Check line from squeegee to recovery tank
3. The safety shut-off valve and switch may have activated to pre
vent further fill
