PRESSURE MEASUREMENT

* Be careful when performing hydraulic connections. High pressure hydraulic oil shower can cause
serious injury.

8.8.1 Measurement

Hydraulic system pressure is measured as follows:
- warm the hydraulic system to normal operating temperature
- adjust the engine rotating speed in such a way that the flow in the hydraulic system is 30 l / min.
- Squeeze the grapple completely shut
- Keep the flow still connected to the grapple cylinder, even if the grapple is already squeezed fully
shut.
- Read the system pressure to P2 connector from the connected pressure gauge
- release the valve levers to the center position and read the free flow pressure
DANGER OF High-pressure liquid jets!

High-pressure jets of oil can shoot out of faulty hydraulic hoses
and cause serious injury when coming in contact with skin.

Never try to locate a leak by palpating.

If the system has pressure accumulators, they must be depressur-
ised before maintenance procedures!
