Operating the Machine
4-4
4. Engine Air Cleaner Dust Valve - Check for a plugged dust cap valve.
Unplug the valve and clean the air cleaner dust cup if required.
5. Transmission - Cold Oil Level - Engine Off- This check is made only
to determine if the transmission contains sufficient oil for safe starting.
Make sure the oil level is well above the upper mark on the dipstick. Add
oil if oil is close to or below the lower mark.
6. Hydraulic Tank - Oil Level Check - Operate the body hoist cylinders
to their fully-extended positions to charge cylinders and lines then lower
the body. With the engine off, oil should show in the sight gauge (6a). Add
oil, if low, through tank filler cap (6b). Check the filter restriction indicator/
gauge, with the oil at operating temperature. If the needle is in the green
section of the gauge, the filter condition is acceptable. If the needle is in
the red section, the differential pressure across the filter has exceeded
1.2 bar and the filter element must be renewed. It is not unusual for the
gauge needle to be in the red section when the oil is cold, which is
acceptable, and therefore only perform this check when the oil is at
operating temperature.
7. Brake Cooling Tank - Oil Level Check - With the engine off, oil
should show in the sight gauge (refer to 7a). Add oil, if low, through the
tank filler cap (refer to 7b)
