Hydraulic System Checks
If the hydraulic system fails to operate
completely, or does so extremely slowly,
carry out the following procedure.
Check that the hydraulic tank is full of oil
to the correct level. The level is correct
when the cone at the base of the filler neck
is visible.
Check that the filter has been regularly
cleaned in accordance with the
maintenance schedule. If not, clean filter.
Check that the hydraulic pressure is correct
as follows:
HYDRAULIC TIP
Fit a 3000 lb/in
2
gauge into the
hydraulic system at the base of the
skip ram.
Operate control lever to tip skip and
check the pressure reading on the
gauge when ram is fully extended and
relief valve is 'blowing'.
GRAVITY TIP
Fit a 3000 lb/in
2
gauge into the
hydraulic circuit between the relief
valve and the steer valve.
Turn the steering wheel to full lock and
check the pressure reading on the
gauge when full lock is reached and the
relief valve is 'blowing'.
See"Specifications" for correct pressure
If this procedure does correct the
fault, contact your Distributor.
Periodically check the supply hose
between the pump and the hydraulic tank
to ensure that it is not deformed. Any
deformation in the hose may result in a
restricted flow and damage to the pump.
Every 10 operating hours, or daily
Check hydraulic oil level
Do not check oil level before closing the
tipping rams, and the engine has been
stopped for 2 minutes.
The oil level (A) is correct when the cone
(B) at the base of the filler neck is visible.
Do not overfill; it will cause leakage from
the breather!
