The TOW-DRIVE lever (18) is located to the left of the operator's seat. The
lever is normally in the DRIVE position. To tow the crane, position the lever to
TOW which will disconnect power to both drive shafts. This will also cause
the 2/4 WHEEL DRIVE lever (17) to move to the 2-WHEEL position because
of an interlock between the two levers. The solid link that secures the front
axle straight must be installed and the rear axle steer cylinder disconnected
before towing the crane.
FOOT THROTTLE PEDAL.
The foot throttle pedal (19) is the right most pedal on the cab floor. The pedal
operates the engine speed governor through a control cable. Depressing the
pedal increases engine speed up to the governed speed. Releasing the pedal
returns the engine to idle speed.
FOOT BRAKE PEDAL.
The foot brake pedal (20) is the second pedal from the right on the cab floor,
Depressing the pedal actuates the Hi-Power brake boost unit to control
application of the service brakes. Should a loss of boost pressure occur, the
emergency service brake system of the Hi-Power brake boost unit will be
activated and depressing the pedal will cause application of the service
brakes. If both boost systems fail, depressing the pedal will apply the service
brakes proportional to pedal pressure.
H E A D L I G H T DIMMER SWITCH.
The headlight dimmer switch (21) is located on the left side of the cab floor.
The switch controls the headlight high or low beam intensity.
PARK BRAKE LEVER.
The park brake lever (22) is located on the left side of the cab near the floor.
When pushed down, the lever actuates the park brake which locks the front
axle drive shaft. The brake is released by pulling the brake lever.
The EMERGENCY SERVICE BRAKE SYSTEM ACTIVATED indicator (23) is
located on the left side of the front console. The indicator is a red light that is
on when the emergency system of the Hi-Power brake boost unit is
energized due to a failure of the normal boost pressure.
