Hydraulic Jacks JH G-plus Series
= with slide shoe guiding
These jacks are designed specifically for lifting heavy loads vertically.
• They should only be used on solid level ground. Do not use on a
slope. The load must have a suitable strong pick-up point which will
accept the full surface of the lifting toe.
• The centre of gravity must be in the under half of the load
Do not exceed the maximum load recommended in this document
and shown on the identification plate on the jack.
• Always lower the jack slowly and carefully. Otherwise the guide of
the housing may be damaged due to high friction forces.
• Every other use than recommended must be avoid. The
manufacturer or supplier is not liable for any damage resulting from
improper use of the jack. Accidences resulting from improper use
are the responsibility of the user.
These products are not designed:
• For lifting and moving people or mobile devices.
• For use in extreme environment (i.e. under hazardous, explosive,
flammable or corrosive conditions)
• Materials and lubricants used may not meet local food and
agricultural industry regulations
The user
should read these operating and service instructions
carefully before attempting to use the jacks. Particular attention
should be paid to the safety instructions on page 8.

Operating instructions for all models
Recommendation:
Work in tandem with two jacks when lifting very large loads.
Use a JUNG central pump ( in picture A).
Attention
: When working with two hydraulic jacks, fitted to a central
pump, please note that is only one hydraulic circuit i.e. the hydraulic fluid
can flow between the jacks. The jacks should be very carefully positioned
under the load, keeping in mind the location of the centre of gravity to
ensure stability and prevent the load from tipping over.

Working with JH 50 G-EX the steps 1+2 only can
be done using external pump.
In purchasing the JUNG jack, you have made a wise decision. This small power
package makes your lifting and transport jobs child’s play.
The drawing on the left illustrates a possible combination for the ideal use of JUNG
equipment.
All units can be stored in a minimum of space, are easily transportable and are
therefore an indispensable help when travelling.
1. Lift loads. (moving pump lever up and down)
2. Lower loads. (loosen lowering screw)
3. Fitted in this way, the pump lever can be used as
4. a handle bar for castor-mounted jacks
