9.3 Maintenance work
Potential crushing and shearing
hazard to limbs caused by unc-
ontrolled lowering motion.
In particularly dirty environments, maintain
the post lifts accordingly more frequently.
Only perform maintenance on unloaded lifts,
i.e. without vehicle.
Before maintenance work lower the main lift
completely or lower and latch into the lock
(locking latches).
Turn the main switch to OFF ("OFF“ setting)
and lock with a padlock.
Cordon off the maintenance area to
unauthorized persons (red-white chain,
warning notices).
Disconnect the air supply (Compressor unit
manometer to 0 bar).
Inform all persons in the area about the
maintenance work.
Risk to people and the environment
caused by toxic substances when
emptying or filling the hydraulic
oil tank or lubricator (Compressor
unit).
Avoid contact with or inhalation of hydraulic
oil or Vaseline oil.
Provide a suitable oil drain pan and oil
absorbent.
Ensure that used oil does not contaminate
the soil or wash away into the drainage
system.
Comply with local regulations for handling
water pollutants.
Dispose of used oil in an environmentally
friendly manner.
Hydraulic oil is highly inflammable, combus-
tible.
Risk of fatal injury if anchor bolts
are loose. Post lift may slip, the
load may collapse.
Stop operating the post lift.
Secure the post lift. If this cannot be done,
provide an approved foundation then anchor
and secure the post lift properly.

parts should be kept free of corrosive
agents,solvents,and road salts. if such
agents are spilled or splashed on any lift
component,immediately rinse thoroughly with
water and wipe down with a clean rag. Spray
wire rope cables as required with penetrating oil .
2. Check whether the automatic wheel chocks,
drive-on ramps, or the chocks and drive-on
chocks are damaged or show signs of wear.
