MAINTENANCE OF FORKLIFTS - OD1660 - LESSON 1/TASK 1
(1) After he drives the truck to a desired parking area, he
removes his foot from the accelerator pedal.
He then depresses the
brake pedal slowly and brings the truck to a gradual stop.
(2) He places the FWD-NEUT-REV control lever in the NEUT position
and, if the truck is to be parked, he applies the parking brake and
allows the engine to idle from three to five minutes. He then pulls
up the normal engine shutoff handle and turns off the ignition switch
(figures 2 and 3 on pages 5 and 6).
NOTES
In case of an emergency, the operator pulls up
the EMERGENCY STOP CONTROL to stop the engine.
To restart the engine after the EMERGENCY STOP
CONTROL has been used, push the EMERGENCY STOP
CONTROL down.
The EMERGENCY STOP CONTROL reset
lever, located on the left side of the engine,
must be pushed toward the cylinder block.

Hydraulic System
The hydraulic system has three pumps:
the main pump, an engine
driven pump, and the rear steering pump.
a.
Main Pump. The main hydraulic pump is mounted on and driven by
the transmission. This pump is actually two separate pumps assembled
on a single shaft common to both pump sections.
(1) The longer (or rear) portion of the main pump supplies
hydraulic pressure to the lift cylinders and to the extension
cylinders.
The front or smaller portion of the main pump supplies
pressure for front wheel steering. The pump is located on the rear
of the transmission facing forward (figure 6 on the following page).
(2) Maintenance is an important function to be performed on the
forklift truck; however, we will only cover cleaning and inspection
of the major components.
