Welded chassis (from 16 t or on request):
• The chassis was manufactured according to your pit size; the roller
collar must make contact with the running rail.
• Here again, the maximum distance between the roller collar and the
running rail must not exceed 10 mm.
►
In general, the following applies to both the adjustable and the welded
chassis
• The standard running rollers are authorized only for flat to slightly
conical contact; they may need to be adapted by re-turning to more
tilted running rails. For an extra charge we will provide the corres
-
ponding rollers (sketch required!).
•
It is not permitted to extend the rollers to compensate for misalign-
ment.
• It may be necessary to straighten the pit by welding in compensating
profiles. Protruding concrete, interfering piping or wiring, etc. must
be removed.
• Suspend the lift in the chassis; mount the locking bracket according
to the instructions.
3.3.
Bleeding
• If the lift (hydraulic unit) has drawn in air due to oil level too low, oil
must be filled in the head plate at the oil nozzle when the piston rod
is
lowered
.
• Extend lift completely and fill 0.1 l of hydraulic oil at the unit.
• Open the bleed screw on the right of the head plate by 3 turns,
• Move lift completely to the top (against stop) and keep running until
only oil still discharges.
• Close bleed screw.
• Lower lift completely; if necessary press piston rod completely to the
bottom by hand. In doing so, excess oil may discharge at the unit.
