Frequently check the oil in the tank for level
and deterioration when the vehicle is in service,
and add or change oil in time upon detection of
any abnormal conditions. Wipe the oil tank clean
when checking the oil level. Then unscrew the
oil dipstick assembly, clean and refit the oil dip-
stick, then remove it and observe oil level. If the
oil level is not between MAX and MIN marks of
oil dipstick, hydraulic oil of the same grade
should be added.
Replacement method
1. Wedge the front and rear of the rear wheels
with triangular blocks, engage the
transmission at neutral gear, and jack the front axle to raise the tires of both sides
off the ground, or disengage the drag link from the pitman.
2. Wipe the oil tank clean first, unscrew the tank cover fastening nut to open the tank
cover, unscrew the drain bolt of the steering gear and turn the steering wheel
repeatedly to both limits, so as to drain the residual oil out of the oil pump and oil
tank. Keep the engine running at an idle speed when necessary, and turn the
steering wheel to the leftmost and rightmost for several times until no oil flows out
of the port.
3. Tighten the drain bolt after confirming that the oil in system has been drained
completely, and replace or clean the oil tank filter element.
