7.1 Checking the Charge Pressure
In order to check the charge pressure, the following steps should be taken:
1. Park the truck in a designated service
area in accordance with the
recommended parking procedure.
2. Lower the mast fully and tilt the mast
fully forward.
3. Switch off the engine and remove the
key from the ignition.
4. Open the bonnet from the right hand
side of the truck to gain access to port
‘G’ (
A
) on the drive pump.
5. Wait until the hydraulic pumps are cool
enough to touch before proceeding.
6. Clean and dry the area around port ‘G’
thoroughly
to
prevent
any
contamination from entering the
hydraulic system.
7. Unscrew and remove the hose end from port “G” on the bottom of the pump and
seal the open end with a 9/16“ JIC male plug.
DO NOT
permit any contamination
to enter the hydraulic system.
8. Unscrew the hydraulic adapter from port ‘G’ and screw in a manometer test point
adapter. Attach a pressure gauge -
capable of reading pressure up to 40 bar
(580 PSI)
– to the test point adapter.
9. Start the engine.
10. The pressure should read between
22 - 25 bar (320 - 362 PSI)
when the engine
is idling.
11. Contact your local service representative or Combilift service if the charge
pressure is outside the specified range.
12. Remove the gauge and refit the hydraulic adapter and hose. Apply a suitable
thread sealant to the threads on the adapter before refitting.
13. Clean up any oil spills immediately.
Warning
Ensure that the engine is switched off until the pressure gauge has been
attached securely.
