solution tank sight gauge. When using the bucket
ll-port,stopllingwhenthelevelreachesthe
bottomedgeofthell-port.
NOTE: When lling the solution tank with a bucket,
make sure that the bucket is clean. Do not use the
same bucket for lling and draining the machine.
WARNING: Do not put any ammable
materials into solution tank. This can cause
an explosion or a re. Only use recommended
cleaning chemicals. Contact Dealer for
recommendations on proper chemicals.

OPERATOR MANUAL
CIRCUIT BREAKER
The machine is equipped with a resettable circuit
breaker (see machine components, item #21) to
protect the Main controller. If the circuit breaker
should trip, it can't be reset immediately. You must
rstdeterminewhatcausedthebreakertotrip,and
allow the Controller to cool down and then you can
manually reset the circuit breakers.
NOTE: Contact Dealer for machine repairs.
HOUR METER
The hour meter (see Panel components, item
#12) records the number of total hours the brush
motor has been powered on. Use the hour meter
to determine when to perform recommended
maintenance procedures and to record service
history.
TANK DRAINING

2. With the squeegee and scrub head in their "up"
position, transport machine to approved area for
draining tank(s).
DRAINING THE RECOVERY TANK
Anytimescrubbingiscompleted,orwhenrelling
solution tank, the recovery tank should be drained
and cleaned.
WARNING: If the recovery tank is not
drained when the solution tank has been
relled, foam or water may enter the oat shut-
off screen and cause damage to the vacuum
motor.
1. While holding the drain hose (see machine
components, item #25) upward, remove the cap
and lower hose to drain.
2. Open the recovery tank cover and rinse out the
tank. Use a rag to remove any excess dirt.
3. Cleantheoatshut-offscreenanddebristray
located in the recovery tank .
DRAINING THE SOLUTION TANK
Any time scrubbing operation is completed, the
solution tank should be drained and cleaned.
1. Pull the solution tank level hose (see machine
components,item#23)offthehosetting,this
willallowthesolutiontoowfreelyintoabucket
oroordrain.
2. Removethecoverofthelterassembly(see
machine components, item #29) to drain the
solutiontank,checkthelterscreenandclean
up it if necessary.
3. Rinse the solution tank with clean water after
every use. This will help prevent chemical
buildup and clogging of the solution lines.
4. After rinsing out the tank, securely reconnect
thetanklevelhosetothehosetting,replace
thelterassemblycoverandbesurethelter
