Recommendations for Operation of
the HPS
When assembling the HPS:
• Install properly the oil pipelines and
hoses in accordance with the hydraulic
diagram;
• Protect the connecting holes of the
metering pumps, hydraulic cylinders, poi
pipelines and high-pressure hoses
against penetration of dirt;
• Prior to starting the engine, check the
tightening of all the connections of the
HPS hydraulic system;
• When tightening the fasteners, apply
the required torque;
• Fill the oil tank to the upper limit as
seen on the level indicator;
• Bleed air from the hydraulic system. To
do this, proceed as follows:
1. Start the engine. Turn the steering
wheel in both directions 3-4 times at the
idling rotational speed of the engine
without reaching the extreme positions
of turning of the steerable wheels. Add
oil to the tank to the required level.
2. Turn the wheels from one stop to an-
other 2-3 times. Hold the steering wheel
at the extreme positions for 4...5 sec-
onds.
3. If necessary, eliminate the oil leaks
and add oil to the top level of the tank.
• Drive the figure of eight to check the
operation of the steering control.
