   NOTE: Brush motors will not work when the scrub head assembly raised.
   NOTE: See TANK DRAINING section to learn how to drain recovery and solution tanks.

CIRCUIT BREAKER/FUSES
The machine is equipped with 2 resettable circuit breakers(see machine components, item #11, item# 33) to protect the drive motor and the vacuum motor from damage. If the circuit breakers should trip, it can’t be reset immediately. You must first determine what caused the breaker to trip, and allow the motor to cool down and then you can manually reset the circuit breakers.
The machine is also equipped with a 60A fuse to protect the brush motors from damage. When replacing a fuse never substitute a higher Amps rated fuse than specified.
HOUR METER
The hour meter (see machine components, item #3) 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.
EMERGENCY STOP BUTTON/BRAKE
The machine is equipped with an Electromagnetic Brake Mechanism on the Transaxle. When in case of Emergency, release the Control Handle bail(see machine components, item #25) or strike the Emergency stop button (see machine components, item #10), the machine will be braked and then stop. Reset the emergency stop button, turn on the Main power key switch, and then pull the control handle bail, the machine will be restart.
NOTE: The machine can not be moved unless the Main Power Key Switch and the Control Handle bail be turned on.
WARNING: Do Not Change the Default Settings of the Electromagnetic Brake Mechanism unless Authorized, otherwise it may cause Machine Damage or Personal Injury. Contact the Authorized Service center for machine repairs.

TANK DRAINING

1. Turn the machine off.
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 refilling solution tank, the recovery tank should be drained and cleaned.
WARNING: If the recovery tank is not drained when the solution tank has been refilled, foam or water may enter the float shut-off screen and cause damage to the vacuum motor.

1. While holding the drain hose (see machine components, item #22) 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 float 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 #12) off the hose fitting, this will allow the solution to flow freely into a bucket or floor drain.
2. Remove the cover of the filter assembly(see machine components, item #20) to drain the solution tank, check the filter 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 fitting, replace the filter assembly cover and be sure the filter screen and the “0” ring is in the correct position.
