Hydraulic system
The hydraulic system is comprised of a cylinder pump unit with a built-in lowering valve, safety valve and built-in
overpressure and non-return valve.
Apart from the inspections required in accordance with the maintenance instructions and the stipulated oil change,
the hydraulic system should require little maintenance.
Before starting any maintenance or repair work on the hydraulic pump, always first make sure that it is not under
load (make it unpressurized).
Never use the hydraulic pump without oil!
To change the oil, the oil must be suctioned out of the oil tank.
After the oil has been changed it may be necessary, or whenever needed otherwise, to bleed the air from the
hydraulic system.
Only ever bleed air from the system when not under load.
Check the oil level!
Bleeding the air
Actuate the hydraulic system several times when not under load (lift and lower).
