WARNING - safe usage instructions
1. The beam shall only be mounted on lifts or in pits
approved by the manufacturer to support jacking beams.
2. The beam shall be mounted on parallel and horizontal
support rails and shall be secured to prevent beam from
crashing. Verify before each lift that the supports are safely
positioned on platforms or pit rails.
3. Study, understand and follow all instructions before
operating this equipment.
4. Rated capacity of beam shall be max. 66 % of vehicle lift
capacity. Do not exceed rated capacity.
5. When two beams are mounted on a lift they shall only be
operated with a min. distance of 4 meters between the
two beams. Do not exceed vehicle lift capacity.
6. The cylinders shall be placed one on each side of beam
center line.
7. This is a lifting device only. Immediately after lifting,
support vehicle with appropriate means.
8. Do always keep the load in horizontal position. It is
recommended only to operate lock valves, with release
closed and control valve in neutral.
9. When using only one cylinder, ALWAYS keep the lock
valve on the unloaded cylinder closed. It is recommended
to use the optional diff beam instead.
10. When using the diff beam (optional) ALWAYS keep both
lock valves open!
11. Jacking beams with mechanical locks (optional): When
released (control valve fully down), always stop lowering
(close the release) before reengaging the mechanical
locks.
12. Lift only on areas of the vehicle as specified by the vehicle
manufacturer, and only centrally on the saddle.
13. Support load horizontally through it's centre of gravity and
rustehnika.ru
be attentive ensuring that load can't slip.
14. The vehicle must be allowed to run freely during lifting
and lowering (without brakes and in neutral).
15. Use clean and dry air supply, max. 12 bar/170 psi.
16. Only adapters, attachments and spare parts supplied by
the manufacturer shall be used. No alterations shall be
made to this product.
17. Failure to observe these warnings may result in personal
injury and/or property damage.
Mounting of jacking beam: Observe warning 1 and 2!
1. Adjust frame width to fit lift or pit.
2. Lift: Raise lift platforms from the floor and position the
beam between lift platforms using our special trolley or
e.g. a pallet truck. Pit: Use crane or fork lift truck to lower
the jack into the pit.
3. Place the separate support on support rail. Adjust platform
level and mount the support. Repeat this on the other side.
Warning: Tighten to a torque setting of 197 Nm!
4. Then make sure that the beam runs safely and freely
in any position on lift or pit without play. Warning: The
beam must be secured against crashing by tightening
lock 5863002 to a torque setting of 36 Nm! If required
the jack shall be secured against derailing.
5. Cylinder installation: crane the cylinder in a sling and
carefully lower it into the frame, with the hydraulic fitting
towards the control panel (fig. 1).
6. Connect the hydraulic hose to the cylinder, guiding the
hose in a gentle curve around the cylinder (fig. 2+3).
7. The oil reservoir is plugged for transport: pull cover
5863028 towards centre and replace plug with loose air
hose (fig. 4).
8. Connect air supply on rear panel, ¼ WRG: 8 – 12 bar, 350 l/
min; 116 - 170 psi, 13 cfm/min.
9. Run the cylinders fully up and down 3 – 5 times in order

to bleed the hydraulic system.
10. Check the function of the jacking beam by lifting a
typical vehicle on lifting areas as specified by the vehicle
manufacturer. Carefully test and learn the function of the
various controls.
Operation
The lock valve in each cylinder nut is for operating the
cylinders individually in order to keep the load horizontally by
opening or closing the valves. The cylinder will neither lift nor
lower with the valve closed. See warnings 8, 9 and 10!
The release located in the center of the control panel is used
for lowering.
The control valve located on the right centre of the control
panel controls lifting, and lowering without load.
Mechanical locks (optional): The two mechanical locks on
each cylinder will lock (engage) automatically when lifting
or lowering. The locks are released by continually turning
the control valve fully down. If the locks are engaged it is
necessary to lift a few cm to allow releasing.
Lifting: Check that both lock valves are open. See warnings
8, 9 and 10!
Turn the control valve upwards. First stage is air-operated high-
speed approach. Turn further and the air-motor starts for power
lift operation. Use the lock valves to keep the load horizontally:
close the cylinder having the correct height and then adjust the
height of the other cylinder by lifting or lowering.
Lowering: Check that both lock valves are open. See
warnings 8, 9 and 10!
Carefully open the release counter clockwise. Use the lock
valves to keep the load horizontally by partly or completely
closing the lowest cylinder. The cylinders - when without load
- must be drawn down by vacuum: Keep the release open
and then turn the control valve downwards.
Lowering cylinders with mechanical locks (optional):
Check that both lock valves are open. See warnings 8, 9 and
rustehnika.ru
10!
If necessarily at first lift a few cm in order to be able to
release the mechanical locks. Then turn the control valve
fully down to release the locks – and keep the valve down!
The mechanical locks will lock (engage) unless activated by
the control valve. Always stop lowering before reengaging -
please refer to Warning 11.
Then carefully open the release counter clockwise. Use
the lock valves to keep the load horizontally by partly or
completely closing the lowest cylinder.
The cylinders – when unloaded - must be drawn down by
vacuum: Keep the release open and the control valve turned
fully down.
Noise emission: the A-weighted emission sound pressure
level is 80 dB(A).
Users Maintenance
Maintenance and repair must always be carried out by
qualified personnel.
The air supply shall be clean and dry in order to avoid rust
and water in the system. It is recommended to install water
separator/filter and oil lubricator on the air supply, close to
the beam.
Cleaning: We advice not to use high pressure cleaner,
steam jets or degreasing agents in order to avoid degreasing
and penetrating water. If so mechanical parts must be
lubricated afterwards.
Daily: Verify before each lift that the supports are safely
positioned on platforms or pit rails. Check filter and oil
lubricator.
Monthly: Check tightening of 2 x 8 screws for supports and
2 x locks 5863002. Check that any safety brackets against
derailing are mounted and adjusted correctly. Oil all sliding
areas and moving parts. Lubricate support rollers or bearings
