Observe the operating instructions.
Always keep the operating instructions available at the place of use.
Observe all safety and danger notes on the lift and keep them legible.
The workshop operator must insure that all safety regulations are observed by the workshop
personnel.
Technological modifications of the lift are not permitted.
The operating instructions are a part of the product and must be handed over to a succeeding
user.
Observe the maintenance intervals.
1.3 Safety-relevant Components
•Hydraulic pressure limiting valve
•Hydraulic lowering brake valve
•Tilt protections [1] on the lifting cylinder
•Pull-out safety devices at the undercarriage (4.2, Positions A)
•Pressure limiting valve

DANGER
Risk of death and severe injury from improper transport
Always transport the lift table with suitable hoisting and transport devices (e.g. forklift or crane).
Never stay under suspended loads.
Safety notes
Hoist the jack at viable spots only.
Move the lifting cylinder horizontally and with the operating elements at the top.
Secure moving and loose parts.
4.1 Make the Lifting Cylinder ready for Operation
Note variants of the hydraulic construction.

4.2 Install and assemble Jack
WARNING
Risk of injury and material damage by crashing jacks
Install jack only on level and solid ground, which has the necessary load-bearing capacity.
Use jack only on load-bearing and parallel rails.
Safety notes
Use jack only with castors that fit the rails.
Only use the jack in the workshop pit or lift for which it was made.
If the distance between the rails of vehicle lifts (e.g. scissor lifts) changes due to alternating load,
additional fuses need to be requested from the manufacturer.
There are five types of undercarriages:
•Undercarriages with sliding axles (adjustable)
•Undercarriages with telescopic carriers (adjustable)
•Single-piece undercarriages (rigid)
•Two-piece undercarriages (rigid)
•Transverse and height-adjustable undercarriages
Undercarriages with sliding axles
Standard castors
A
B
C
Insert undercarriage in rails.
Pull out sliding axes B evenly and set the track width.
Tighten set threaded pins C.
Check the secure support of the castors (standard castors min. 25 mm) over the entire length of
the rails.
Adjust enclosed clamping collars A and attach externally to sliding axles B.
Dismantle the tilt protection bracket [1] on the lifting cylinder, insert the lifting cylinder into the
undercarriage and replace the tilt protection bracket on both sides.
