Check and maintenance:
1. Replace steering gear oil in time
and clean &replace filtering screen in
oil tank when a new truck runs for
3000 -4000km and runs every 5000
km afterwards.
2. Check oil volume and oil quality in
oil cylinder often, adding or replacing
if oil goes bad.
3. Pay attention to the mark of oil inlet
and outlet in pipeline connecting
when strip and re-assemble steering
mechanism to make sure it is con
鄄
nected right. After connecting pipe-
line, check it to prevent air from enter
鄄
ing into oil outlet pipeline of oil pump.
Start engine to make it run in idle
speed and add oil into oil tank. If the
system has not been poured enough
oil, rotate steering wheel repeatedly
left and right to extreme position and
add oil into oil tank at the same time
until oil level in oil tank doesn't drop
and has no air bubble. Add oil until oil
level is marked. When adding, check
oil tank and pipeline connector of
steering system to make sure them
clean, having no impurity. Specific
connect are as follows:
荫
Connect oil outlet to oil inlet of
steering oil pump.
荫
Connect oil return hole of steering
gear to oil return hole of oil tank.
4. When power -steering system
doesn't work, driver can use hand de
鄄
pending on mechanical steering part.
However, using mechanical steering
only for a long time is forbidden.
5. Power -steering system has a
function of spot turn. Be sure to
avoid rotating steering wheel to ex
鄄
treme position to prevent decreasing
life of components.
6. Add liquid oil according to pre
鄄
scription. If surrounding temperature
