BRAKING SYSTEM. (Figure 1-12)
Service brake. Fully depressing the brake and inching pedal applies four hydraulic disc brake assemblies
located inside the front and rear axles. Separate disc brake assemblies are associated with each wheel. Releasing the
pedal relieves the hydraulic pressure and allow the wheel to spin freely. When the pedal is depressed the service lights or
blackout light will illuminated depending on the position for the vehicular lights switch. Hydraulic pressure to the brake
assemblies is produced in the master cylinder. Two separate hydraulic circuits, each with a master cylinder, are used for
front and rear breaks. Should one of the hydraulic circuit develop a leak the other will remain functional to stop the vehicle.
This safety feature will reduce the risk of a total brake failure.
Parking Brake. The parking brake is controlled by a two-position toggle switch. Placing switch in ON
position causes a spring actuated cylinder to apply the two front axle disc brake assemblies. This prevents the front
wheels form turning. Along with applying the brake assemblies, the transmission speed range and directional selector are
disabled preventing the vehicle from engaging in drive. Placing the switch in the OFF position releases the parking brake.
ELECTRICAL SYSTEM. (Figure FO-2)
The electrical system operates on 24 VDC and is charged by the engine driven alternator. Placing the
ignition switch in the START position will power the engine starter to crank the engine. Once the engine is running the
ignition switch is released and remains in the ON position. The hourmeter operates only when the engine is running.
When the ignition switch is in the ON position, the ammeter, engine oil pressure gauge, engine temperature gauge,
transmission temperature gauge, and fuel level gauge are operational. Forklift lights and wind shield wiper will also
functional. If the engine fails to start when air temperature is below 32°F, the COLD START push button may be utilized to
inject ether as a starting aid.
Front and rear flood lights are controlled by two-position toggle switches. The flood lights provide work area
illumination during non-blackout operations. The vehicle lights switch assembly provides control of the forklift lighting
functions. Warning indicators are provided to assist the operator in isolating forklift malfunctions. All the warning lights will
illuminate when the ignition switch is placed in the ON position without the engine running. The front differential lock is
operated using the FRONT DIFF LOCK switch. Placing the FRONT DIFF LOCK switch in the on position engages the
front differential mechanism while the OFF position disengages. The engine and all forklift power is shut down by placing
the ignition switch in the OFF position.
