For operator ergonomics, the control panel houses all the primary functions. Controls are grouped in a central area
at the rear of the machine.
Bail Handle
(A) When the scrubdeck is lowered to the floor, The Bail Handle Enables the brush motor and moves the machine
forward once depressed. This also allows the operator to automatically load the brush when the scrubdeck is
lowered.
Handle Adjustment Knobs
(B) Allows the handle position to be raised or lowered.
Key Switch
(C) Controls the machine’s power (Brush Unload/Off/On) with a key for safety. This switch, when turned counter
clock-wise, operates the auto brush unload when scrubdeck is in the raised position. When it is turned to the on
position, the machine will operate.
Squeegee Lift Lever
(D) When actuated to the top position, the squeegee is lowered and the vacuum motor is turned on. When locked
in the bottom position, the squeegee is raised and the vacumm motor shuts off.
Solution Control Lever
(E) This lever controls the rate at which solution is put down. Moving the lever up will increase the amount of
solution. Moving the lever down will decrease the solution rate. Moving the lever all the way down shuts off solution
flow.
Battery Gauge
(F) This gauge displays the remaining battery charge.
Charge Status Indicator
(G) This gauge displays the status of the batteries during charging. The gauge has a readout of 3 LEDs. 1 Green,
1 yellow, 1 Red. Green indicating a full charge, Red indicating the batteries are charging.

Battery Compartment
The battery compartment is located under the recovery tank. The Battery compartment can be accessed for servicing and maintenance by tilting the
recovery tank (make sure recovery tank has been
drained before tilting). The battery compartment
contains two 12-volt batteries connected in series.
Connect the batteries according to the battery connection diagram (see diagram). The recommended
batteries are 105Ah (Minuteman P/N 956712) or
100Ah (minuteman P/N 956100) Gel. The battery

Rear Squeegee
The rear squeegee is the main element of the conduit that transfers the spent solution
into the recovery tank. A daily maintenance check of this component is essential to have
optimum machine performance. The blade configuration has two usable edges and can
be turned inside out to utilize the opposite side of the blade. If streaking occurs it is time
to turn the blade to good edge or replace if this has already been done. The blade can be
accessed by removing the 6 adjusting nuts (A), 2 bumper wheels (B), and the squeegee
mounting bracket (E).

There are 5 angular positions 11.25° apart for a
total of 45° between the minimum and maximum
position.
Horizontal Adjustment
The horizontal position can be adjusted by
removing the 4 mounting bolts (B) (2 each side)
with a 9/16” socket and sliding the mounting plate
(P) to one of the 3 available positions. The machine

the Solution Tank Drain Hose (A) from the
Hose Barb (B) and routing the hose to a floor
drain.
Solution Level Indicator
The Solution Tank Drain Hose also serves as a
water level indicator for the solution tank. The
amount of water remaining in the solution tank
can be seen through the clear drain hose. Level
markers molded into the solution tank are
positioned at 1/4, 1/2, 3/4, and full levels.

scrub deck by pressing down
on the deck lift pedal . Make
sure the pedal is in the “home”
position shown below.
Lower the scrub deck by
releasing the deck lift pedal.
Momentarily (1 to 2 seconds)
turn the key to the “Brush
Unload” position.
Note: The brush will release
only when the key returns to the
off position (O).
With the key turned on, pull the
bail handle to spin the scrub
brush onto the scrubdeck.
If done correctly the brush

Screened Float
If the recovery tank (C) is overfilled or a large amount
of foaming is present, the screened float (B) blocks
the vacuum intake inside the tank protecting the
vacuum motor and internal electronics from water
damage. It is essential to keep the float in working
order through regular maintenance.
The float should be cleaned daily by thoroughly
rinsing with a hose. Removal of the screened float
is not necessary for daily maintenace.
At least once a month the screened float should be
completely removed, cleaned, and checked for any
damage to the seal or metal screen.
WARNING: Damage to the machine may occur
if operated without the screened float properly
in place.
