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.
