Every time that it is retracted, the piston rod passes completely through
the plunger system into the hydraulic oil, and is thereby automatically
lubricated and protected against corrosion.
The hydraulic oil must be changed after no more than six years of
operation. The initial fill at the factory is with BP HLP HM 35.
A comparable oil can be used when changing the oil.

Oil level check
Important for oil level check
►
Disconnect the pit lift from the compressed air network!
►
Check oil only when unit is not under pressure
►
Check oil only when lift is not in motion.
►
Ensure absolute cleaniness
► Use only filtered hydraulic oil
►
Check oil level at least once per month.
Bleeding
The pit lift is supplied filled with oil, and has been bled. If, after an
extended period of operation or after an oil change, the piston rod
extends jerkily, then the bleed screw underneath the head plate
on the cylinder should be opened until oil escapes.

General
• Quite often the problems that cause a malfunction are minor. Lo
-
cating the cause of a malfunction is almost always the most time-
consuming task in troubleshooting. As an automotive expert, you
can carry out nearly all troubleshooting tasks yourself, in order to
save money.
• Before shipping, every lift is subjected to several precise function
tests under operating conditions with an excessive load. In addition,
a seal check and completeness check are carried out.
However, if parts are missing at the time of delivery, or if malfunctions
occur during commissioning, then in our daily experience the cause is
in most cases beyond our control.
