3. Use only on hard level surface.
4. It is recommended to brake and chock the vehicle.
5. Lifting device only. Immediately after lifting, support
the vehicle with support stands.
6. Lift only on areas of the vehicle as specified by
the vehicle manufacturer, and only centrally on the
lifting saddle.
7. No person should remain in, on, or get bodily
under a load that is being jacked or is supported
only by a jack.
8. Do not use more than 2 standard extensions in
sequence.
9. No alterations shall be made to this jack.
10. Maximum air pressure: 12 bar/170 psi.
11. Failure to follow these warnings may result in

Assembly
To mount the handle turn the jack upside down.
IMPORTANT: The hoses must be twisted around the
tube as shown on the photo.
WARNING: Do not operate the jack in this position or
lying on the side - if so there is risk of oil spillage.
Oil mechanical parts before first use.
Air connection: ¼" WRG.
Full capacity from 9 bar/125 psi. Maximum air
pressure:12 bar/170 psi.
Use of the jack
Transport: The jack is to be stored or transported
standing on its wheels. If need be the jack may be
transported lying on the left side observed from the
handle side, but in this case a little oil spillage from the
air motor might occur.
Lifting: turn the control valve clockwise until the pump
starts.
Lowering: turn the control valve counter clockwise.
Always lower the jack completely in order to protect
the lifting cylinder.
The handle offers 3 different positions: pull the handle
and tip as required.

Maintenance
Maintenance and repair must always be carried out by
qualified personnel.
The air-motor requires oil to lubricate the mechanical
parts. It is recommended to use air supply with water
separator/filter and oil lubricator.
Daily: Lubricate the air-motor by injecting a little oil
into the air connection on the handle and then lift to
max. position. Disconnect the air hose, inject further
oil into the air connection, reconnect the air hose and
turn the control valve counter clockwise to lubricate the
cylinder walls.
Monthly: Empty water separator/filter and fill oil
lubricator with oil. Lubricate all mechanical parts with
a few drops of oil. At the same time inspect jack and
extensions for damage and wear and tear.
Oil level: refill oil through hole (9) on left-hand side
of cabinet. Correct oil level is to the lower edge of
the hole with the jack horizontal and the cylinder
completely lowered.
Quantity of oil: 2,5 l.
Use high quality hydraulic oil, viscosity ISO VG 15.
Never use brake fluid!

Safety Inspection

According to national legislation - minimum once
a year though - the jack must be inspected by a
professional: Damages, wear of cylinder bottom below
plug 0258400, wear and tear, adjustment of the safety
valve, cylinder and pump for leakages. Furthermore
that all safety labels are legible.
Troubleshooting
1. The jack does not lift to maximum postion even
though the air motor is running: refill with oil.
2. The air motor runs slowly or stops: the air filter
(handle drawing, no. 8) in the air connection is
blocked and needs cleaning or changing.
3. The load is dropping: change valve cores in pump.
PLEASE OBSERVE that the valve cores are to be
tightened slightly only: tighten to a torque setting of
10 Nm).
4. The cylinder is leaking: Change cylinder seals.
A sudden oil leak from air motor or handle might
be caused by wrong handling, e.g. if the jack has
been lying on the side. If so the oil leak (from the reservoir) will stop, when the jack is standing on the
whells again - but oil drips will continue for a while.
Spare parts
Replace worn or broken parts with genuine jack
manufacturer supplied parts only. All major parts may
not be provided after discontinuation of a model.
Destruction
Oil must be drained off and legally disposed of.
