HYDRAULIC PRESSURE SETTINGS
The hydraulic system has three pressure settings which have to be set as follows:
Before any testing is carried out run the engine and hydraulic system to warm the hydraulic oil. The
oil cooler fan will engage at between 60 and 65°C (145°F).
All pressure settings are performed with the oil cooler fan on and engine running at full speed
(3,600 rpm).
OVER CENTRE VALVE
Connect an accurate pressure gauge with a range
0-300 bar (0-4,300 PSI)
to the
Test Point.
The pressure should be set at: 31-34 bar (450-500 PSI) for the 11.3cc Pump
NOTE:
If adjustment is required slacken off the lock nut and using a 5mm hex key wind in the screw
in to increase the pressure or out to reduce the pressure. Retighten the lock nut when adjustments
are complete.
MAIN SYSTEM RELIEF PRESSURE
Connect an accurate pressure gauge with a range 0-300 bar (0-4,300 PSI) to the Test Point .
Check the pressure while pulling the
tilt control lever
at the end of the ram’s stroke.
The pressure should be set at: 207 bar (3,000 PSI) for the Petrol models and 220 bar (3,200
PSI) for Diesel Models.
NOTE:
If adjustment is necessary slacken off the lock nut on the main pressure relief valve and wind
in the screw to increase the pressure or back off the screw to reduce the pressure. Retighten the
lock nut when adjustments are complete.
LIFT PRESSURE
Connect an accurate pressure gauge with a range 0-300 bar (0-4,300 PSI) to the Test Point. Check
the pressure while pulling the arm control lever at the end of the ram’s stroke (boom fully raised).
The pressure should be set at: 165 bar (2,400 PSI) for Mid Range Loaders.
NOTE: If adjustment is necessary unscrew the cap lock nut on the lift pressure relief cartridge and
wind in the screw using an allen key to increase the pressure or back off the screw to reduce the
pressure. Re
fi t and tighten the lock nut when adjustments are complete .
HYDRUALIC FLUID
Replace the hydraulic oil after every 1,000 operating hours.
