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
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.

5. Maintenance:
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.
