Truck Starting
To start the truck, the battery is plugged in, the Master Control ON/OFF switch is in the ON position, the PIN-key code is entered in the
keypad, and the green ON (|) key pressed (or optional key switch is ON). See “Service Display” on page 5-21.
Lift/Lower
The lift/lower system consists of an electrically operated hydraulic pump assembly and related components.
The hydraulic pump assembly consists of a positive displacement rotary gear pump with reservoir mounted to an adapter. A DC electric
motor is mounted to the opposite side of the pump adapter. An adjustable relief valve, check valve, and a solenoid operated lowering valve
are installed within the adapter.
With the forks elevated, the normally closed solenoid valve and the check valve prevent hydraulic fluid from returning to the reservoir.
