BRUSH HEAD FOOT PEDAL
Located at the right rear corner near the floor, this pedal is used to raise or lower
the brush head. There are three positions: up, down, and transport.
*
UP position (Figure 2)
To lifts the brush head for moving the machine from one area to another.
*
DOWN position (Figure 3)
This position is for scrubbing.
*
TRANSPORT position (Figure 4-5)
This will lift the brush head higher than the “up” position for clearance
on inclines, such as ramps. Remove the squeegee and brush(es) or
padholder(s). Push the pedal forward under the machine, the brush
head will “snap” into the transport position. Swing the pedal to the left
so it is parallel to the floor.
To disengage transport position, swing the foot pedal down to the right
and lift slightly on the brush head and lower.
VACUUM / SQUEEGEE LEVER
Located at the rear of the machine, this lever controls both the squeegee and
vacuum motor. There are three positions: off, vacuum on, and vacuum on with
the squeegee on the floor.
*
Off (Figure 6)
*
Vacuum ON (Figure 7)
This position lifts the squeegee slightly while leaving the vacuum turned
on. This can be used for backing up during scrubbing, or supplies
vacuum for cleaning remote areas using an attachment.
*
Vacuum ON with the squeegee on the floor (Figure 8)
This position is for picking up solution while scrubbing.
CLEAN SOLUTION LEVEL INDICATOR (FIG-
URE 9)
This clear tube, located at the rear of the machine, along with the indicator marks
on the tank will identify how much clean solution remains in the clean solution
tank.
CIRCUIT BREAKERS
Located on the rear of the machine, they provide overload protection to
machine’s motors. If a breaker trips, it will pop out. To reset, wait one minute and
press the button back in. If any breaker trips repeatedly, have the machine
serviced.
HOUR METER (OPTIONAL)
Located on the rear of the machine, to the right of the circuit breaker panel, it will
measure the time the brush drive motor(s) are “ON”.
OPERATION
WARNING!
Fire and explosion can occur when this machine is operated in
areas where flammable solids, liquids, dusts or gasses are
present. Do not use this machine in these areas. Use only with
nonflammable floor cleaners and floor finishing products.
WARNING!
Exposed rotating brush. Contact with brush or resultant thrown
objects, can cause severe injury. Keep clear of rotating brush.
Prevent contact with objects.
Before scrubbing, sweep the area clean of debris. For effective long scrubbing
use, begin with fully charged batteries.
ADDING SOLUTION
CAUTION!
Care must be taken when working with hot water. Water
temperature must not exceed 120°F (49° C). Use non-foaming
chemicals only.
Solution can be added from the front of machine, or the rear. Capacity: 17 gal.
(64 L)
FRONT FILL (FIGURE 10)
Remove the front lid and fill the tank with solution and properly diluted cleaning
chemical. Fill the tank to the metal screen.
REAR FILL (FIGURE 11)
Remove the plug and fill the tank with solution and properly diluted cleaning
chemical. Use the clean solution level indicator on the tank to know when the
tank is full.
SCRUBBING PROCEDURE
With proper brushes installed and the “REMOVE” switch in the “SCRUB”
position, the machine is ready for scrubbing.
Lower the “Vacuum / Squeegee Lever” into the DOWN position. Lower the brush
head with the foot pedal, and push on the drive squeeze bar. Adjust solution
flow, and travel speed on traction drive machines as required. While scrubbing,
overlap passes and reduce speed when cornering to ensure solution pickup.
EMPTYING RECOVERY TANK
Remove the drain hose from it’s holder, remove the plug, and dump contents
into a proper waste drain.
EMPTYING THE SOLUTION TANK
Pull the clean solution level indicator tube off the holder and use your thumb as
a plug. Dump contents into a proper waste drain.
CLEAN UP AND STORAGE
CAUTION!
Avoid damaging electrical circuitry below control panel, clean
panel with damp towel only.
Rinse both tanks daily. Leave tanks’ lids off to ventilate, reducing residue
buildup and odor. Store the machine in a cool dry place.
Avoid prolonged exposure of machine to freezing temperatures during storage
or transporting.
