2. 5 PARKING BRAKE
The loader is equipped with park brakes, located inside the
torque motor. The brakes are activated and de-activated
by the seat bar, via charge pressure. When the seat bar is
in the up position, the brake is activated (Fig. 2.4A). When
the seat bar is in the down position, the brake is off (Fig.
2.4B).
The loader has a parking brake indication light to warn that
the brake is engaged.
2. 6 THROTTLE CONTROL
The diesel engine throttle control is the lever located on
the left hand side of the loader next to the steering control
lever (Fig. 2.5). Engine start and stop are controlled
electrically by the ignition key.
Before shutting off the engine, return the throttle control to
idle position and allow the engine to cool at least 2
minutes.
Pushing the lever all the way forward increases the
engine speed to maximum high idle. Pulling the lever
back decreases the engine RPM.
The engine should always be operated at full speed and
the loader travel speed controlled with the steering
control levers (See Section 2.7).
2. 7 LIFT ARM SUPPORTS
For safety while performing regular service or
maintenance work the loader is equipped with lift arm
supports.
The lift arm supports, when extended, prevent the lift arms
from dropping if hydraulic pressure is relieved or the foot
control pedals are accidentally cycled.
To avoid personal injury,
lower the lift arms, shut off
the engine, raise the seat bar
and cycle the hydraulics to
ensure they are locked.
Then, unlatch the seat belt
and exit the loader. Do not
enter or exit with the engine
running unless as specified
in this manual or under
specific service and backhoe
operating procedures.
