3- HANDLING, TRANSPORT, STORAGE
3.1. Storage
•
Store jacks retracted in a dry place.
3.2. Handling, transport
•
Jacks should only be handled using the handle provided for this
purpose. Avoid carrying jacks using the jacking lever.
•
Do not drop or throw jacks. Impacting the outside of the control lever
may deform the piston making the pump unusable.
•
Before transporting jacks, wedge them so as to stop them from hitting
surrounding items.
•
Make sure Pressure release knob is in “Closed” position to avoid air
being drawn into hydraulic circuit.
4- ASSEMBLY
The only assembly operation required is to fit the hand tube on the pump
lever then to insert the safety pin.
5- USE
5.1. Field of use
The jacks from Hilman are designed for handling objects, lifting or moving
loads from a sufficiently resistant and stationary location (for examples:
concrete floor) using the toe or the head of the jack. The 5 and 10 Ton
jacks can be used either vertically or horizontally. The 25 Ton Jack can
be used only vertically. The body can be positioned in relation to the toe
and the base so as to be able to lift objects in restricted areas. The toe
must always be located above the base so that it can fold into it when the
jack is closed (see sketch).
5.2 Operation
Lifting
•
Turn the release valve knob in a clockwise direction until it is snug (i.e.
Closed Position)
•
Pump by moving the jacking in a up and down motion.
•
Lifting stops as soon as the jacking lever is no longer moved.
Lowering:
•
Slowly loosen the release valve knob by turning it in a counter
clockwise direction (i.e. Open Position). The more the knob is loosened
the faster the load will be lowered.
•
Stopping is instantaneous when the knob is tightened.
Note: When jack is not under a load, it is necessary to press on its head to lower it.
CAUTION
:
It is strictly forbidden to unscrew parts other than the control handle,
except during a maintenance operation
.
