4.6 Pre-Operating Checks
Make sure all cab glass, mirrors and lights
are clean. Test all controls to ensure they
are functioning properly. Select 'REVERSE'
momentarily on the transmission shift selector
to make sure the reverse alarm sounds.
1. Transmission - Hot Oil Level - The parking
brake must be applied and the road wheels
securely blocked while carrying out this
check. With the engine idling, transmission
in 'NEUTRAL' and at normal operating
temperature, the top of the oil column should
be visible in the sight gauge. Add oil if low. If
the top of the column is above the sight gauge,
the transmission is overfull and oil should be
drained.
2. Body and Rear Brake Cooling Hydraulic
Tank - Hot Oil Level - Operate the body hoist
cylinders to their fully-extended positions to
charge all cylinders and lines then lower the
body. With the engine running, and body fully
lowered, the oil level should show in the top
sight gauge. Add oil if low. Under all conditions
the bottom sight gauge should show full.
3. Steering and Braking Hydraulic Tank -
Hot Oil Level - With the engine running, oil
at operating temperature and accumulators
charged, oil must be between the top and
middle sight gauges. Shut down the engine
and operate the steering left and right to
discharge steering accumulator. Operate
treadle valve continuously to discharge
braking accumulators. Oil should show in the
top sight gauge.
