Refilling with Hydraulic Fluid
For measuring and refilling, the piston rod must be fully
retracted
and the
siphon must be disconnected from the air or power supply. The oil level must
cover the oil sight glass at least halfway. If no oil is visible on the sight glass,
hydraulic oil must be topped up.
•
Replace the hydraulic oil depending on ageing, water absorption and conta-
mination, but after six years at the latest.
•
Only use hydraulic oil of the same specification for refilling.
•
If the jack is operated permanently at an ambient temperature of < 15 °C, a
hydraulic oil with a lower viscosity must be used.
•
The pressure hoses should be replaced as required, but must be replaced
after six years at the latest. Record the exchange in the inspection book.
