4. If the squeegee assembly leaves streaks on the

floor, raise the squeegee off the floor and wipe
the blades down with a damp cloth.

: Do not use your fingers to wipe or 

remove debris from the blades, as injury may 
occur. 
5. When the solution tank runs empty, turn off

the brush switch, solution switch and raise the
brush head.  Keep the squeegee down and
continue to vacuum until all the dirty water is
picked up.  (see TANK DRAINING section to
learn how to drain recovery and solution tanks)

: The brush motor is circuit breaker protected 

to protect it from damage.  If this breaker trips, it 
can’t be reset immediately. You must first 
determine what caused the breaker to trip, and 
allow the motor to cool down before you can reset 
the breaker.  The breaker is located on the back 
panel of the control housing. 

TANK DRAINING 

1. Turn the power off on the machine
2. With the squeegee and brush head in their “up”

position, transport machine to approved area
for draining tank(s).

DRAINING THE RECOVERY (DIRTY) TANK

: Any time scrubbing is completed, or when 

refilling solution tank, the recovery tank should be 
drained and cleaned. 

: If the recovery tank is not drained when 

the solution tank has been refilled, foam or water 
may enter the float shut-off mechanism and cause 
damage to the vacuum motor.  

1. Remove the drain hose from the holder, and

place the drain hose over the floor drain.  Twist
off the drain hose plug to begin the draining
process. In order to completely empty the
recovery tank, hinge opens the recovery tank
and let it rest on the support stand.

2. Clean the recovery tank after every use.  Use a

fresh water hose to rinse out the recovery tank.

Be careful not to spray water into the float 
shut-off mechanism. 

: If you are storing the machine for any period 

of time, always leave the clear recovery tank lid 
off the tank so the tank can dry completely and 
smell fresh. 
3. Replace the drain hose plug tightly as soon as

you are done draining the tank.

DRAINING THE SOLUTION (CLEAN) TANK

: Any time scrubbing operation is completed, 

the solution tank should be drained and cleaned. 
1. Pull down on the clear tube (back left of the

machine) to remove it from the hose barb. This
will allow the solution to flow freely into a
bucket or floor drain.

2. Rinse the solution tank with clean water after

every use.  This will help prevent chemical
buildup and clogging of the solution lines.

3. With clean water in solution tank, turn

machine power on, solution switch “on” and
pull the operating triggers.  This will allow the
clean water to flush through and clean the
solution plumbing.

4. Once tank is rinsed, flushed and drained,

reconnect the clear tube to the hose barb.  Be
sure the tube is pushed all the way up on the
hose barb.

BATTERY CHARGING 

: Use only approved chargers with the 

following specifications: 

 

Automatic shut off circuit 

 

Deep cycle charging  

 

Output current of 10 – 20 amps 

 

Output voltage of 24 volts 

: For the best machine performance, keep 

batteries charged at all times.  Do not let them sit 
in a discharged condition. 

: Batteries are dangerous! Batteries emit 

hydrogen gas and an explosion or fire can result.  
Keep sparks and fire away from batteries at all 
times. When charging the machine, make sure the 
battery compartment is left open.
