visible inside. Re-insert the rubber plug in the filler
hole.
b) Venting (Fig. 2)
The hydraulic system has to be vented at least after
each time you add hydraulic fluid. Air pockets may
also form in the hydraulic fluid passages if the jack is
not used for a long time. This is the case if the load
sinks again abruptly after being raised half or only
part of the way.
To vent the hydraulic system, pump up the unloaded
jacking arm approximately half way. Now press your
foot against the jacking arm to exert a little pressure
on the hydraulic system. The lowering screw must of
course be closed when you do this.
Use a screwdriver to press the rubber plug slightly
sideways until the air escapes. Now lower the trolley
jack by opening the lowering screw and repeat the
procedure 2 or 3 times. Air is also vented from the
system via the lowering screw. Any drops of fluid
which may then escape are irrelevant for the jack's
further use. You can now rest assured that there are
no longer any air pockets in the fluid passages and
that the jack will work correctly.
Catch old and escaping fluid in a special
container and deliver to your old oil disposal
center!
6. Raising vehicles (Fig. 1)
Before you raise a vehicle, make sure it is standing on
a firm surface so that the trolley jack does not sink
into the ground under the raised load. In hot summer
conditions the trolley jack may easily sink into tarmac
surfaces and slip sideways.
Pull the hand brake and also secure the vehicle with
chocks if available. Now place the trolley jack under
the vehicle so that the support disk can rest against a
strong part of the floor. On old vehicles with rusted
floor elements there is the risk of the support disk
breaking through the floor.
Make sure that the lowering screw is closed. Use the
jacking bar to pump up the jacking arm to a point
where it is not quite touching the vehicle. You can now
make final adjustments of position to ensure that the
vehicle is raised correctly and safely.
For your own safety, always use at least one jack
stand to provide additional support for a raised
vehicle with only one wheel off the ground.
When you have completed your work, first remove the
jack stand and then lower the jacking arm of the
trolley jack by slightly unscrewing the lowering screw
with the jacking bar. You can control the lowering
8
speed yourself by opening the lowering screw to a
greater or lesser degree. The trolley jack is equipped
with an overload valve on the side of the hydraulic
pump. This valve is set at the factory so that the
maximum load cannot be exceeded.
Do not adjust this valve or you will forfeit your rights
under the warranty if the jack suffers any damage.
Once the jacking arm reaches its highest position, the
safety valve and an overflow device will prevent
additional pressure being exerted on the hydraulic
system even if you continue to pump with the jacking
bar.
The required forces exceed 400 N and must be
reduced by involving more people.
7. Cleaning, maintenance and ordering
of spare parts
Lifting equipment must be serviced and repaired in
accordance with the manufacturer's instructions. The
servicing and repairs must be performed by experts.
7.1 Maintance
All moving joints should be oiled and the roller
bearings of the steering wheels greased every three
to six months, depending on how often the trolley jack
is used. Every hydraulic system is sealed with O-rings
or cup packings which result in wear depending on
how often the trolley jack is used. Repair sets are
available from Customer Service on request. To
prevent damage to the seals, use only acid-free
hydraulic fluid to top up the system.
Catch old and escaping fluid in a special
container and deliver to your old oil disposal
center!
You should always move the hydraulic system (piston)
to idle position (piston inserted) once the trolley jack
is no longer needed. This will protect the precision-
machined surfaces of the piston and the piston rod
from corrosion.
Your trolley jack will give you good service if you use
only high-grade hydraulic fluid. Never mix different
types of fluid! Never use brake fluid, alcohol, glycerin,
dirty fluid, etc.
