9.3 Maintenance work
WARNING
Potential crushing and shearing
hazard to limbs caused by uncon-
trolled 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 unauthor-
ized persons (red-white chain, warning notic-
es).
Disconnect the air supply (Compressor unit
manometer to 0 bar).
Inform all persons in the area about the
maintenance work.
WARNING
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 absor-
bent.
Ensure that used oil does not contaminate the
soil or wash away into the drainage system.
Comply with local regulations for handling wa-
ter pollutants.
Dispose of used oil in an environmentally
friendly manner.
Hydraulic oil is highly inflammable, combus-
tible.
DANGER
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.
Daily inspection
1.
Check whether the automatic wheel chocks,
drive-on ramps, or the chocks and drive-on
chocks are damaged or show signs of wear.
Replace damaged or worn parts.
2.
Check the function of the locking latches on the
main lift (visual inspection). To do so, lock the
main lift in the locking latches then raise and
tension the cable.
3.
Check horizontal alignment of runways. Run-
ways must be horizontally aligned and at the
same height. If not, correct the alignment
(
Chapter 13. Commissioning).
4.
Check the cables and cable sheaves for wear
along their entire length (visual inspection). If
necessary, raise the main lift. Promptly replace
damaged or worn parts.
