• It is imperative that the operator always has a
clear view of the lifting jack and the load during
all movements.
• Never work underneath a raised load unless
it has been secured in place using suitable
means.
• Ensure that the information markings on the
lifting jack are kept in a good condition.
• Never use the lifting jack under the following
circumstances:
- in diffi cult conditions (e.g. very cold or hot
climates, if affected by strong magnetic
radiation) or similar situations
- in conjunction with explosive materials,
mines, etc., or similar situations
- with supplies from electrical networks who-
se voltage, frequency, etc., tolerances differ
from those of the public supply
- to lift loads containing molten metal, acid,
radioactive material or loose goods, etc.,

3. OPERATION
Lifting
Turn the screw of the relief valve clockwise as far
as possible. The trolley jack is now ready to lift.
Assembly the lever like shown in fi gure A. Put
the trolley jack horizontally on a fl at surface, put
the lever in the proper hole and start pumping by
moving the lever up and down.
Shaft supports
After jacking up the car the shaft supports should
be installed. Lower the car by turning the the
screw of the release valve anticlockwise, until the
car rests on the supports. Never work under a car
which only rests on the trolley jack.
Lowering
After the work is fi nished, the car is lifted again
until the shaft supports are clear. Remove the shaft
supports. Turn the screw of the relief valve anti-
clockwise and the car will be lowered. The further
the screw is turned anticlockwise the faster the car
will be lowered.
4. MAINTENANCE
• The lifting jack must be maintained and re-
paired in compliance with the manufacturer's
instructions. Any such maintenance or repairs
must be carried out by specialists.
• Once a month the wheels, shafts and piston
rods should be lubricated with lubricating oil
and grease on the pivots of the lifting rods.
• The tank containing hydraulic oil is a closed
tank which usually does not require mainte-
nance. When frequently used, but at least on
TJ501XX
ce a year, the oil should be changed. For this
2000 kg
purpose the top of the tank is fi tted with an oil
drain plug.
