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

4 Transport, Installation and Assembly
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.

4.2 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

4.3 Compressed Air Supply
The compressed air supply must be provided via a maintenance unit consisting of water separator
and pressure reducer. Attach the maintenance unit directly to the jack.
• Supply pressure: max. 10 bar
4.4 Electrical Connection
WARNING
Risk of injury and material damage due to electric shock
The electrical connection and the protective measures in force in the country are to be installed
and checked by a specialist.
The electrical connection must consist of a cable with a five-pin CEE coupling 16 A, which is
connected to a 400V/50Hz mains. A motor-protective circuit-breaker of 3.8 A must be present.
The manufacturer recommends a suitable cable suspension.
5 Commissioning
Before first operation:
Connect compressed air supply or electrical connection to the jack.
Check the hydraulic oil level. ( 7.5)
Perform the safety test. ( 7.6)
