SAFETY INSTRUCTIONS
The following pictograms are used in these instructions
for use:
In accordance with essential applicable safety
standards of European directives
Denotes risk of personal injury, loss of life or
damage to the tool in case of non-observance of
the instructions in this manual.
Danger - Keep hands away from moving parts
Carefully read this manual before using the machine.
Make sure that you know how the machine functions
and how to operate it. Maintain the machine in
accordance with the instructions to make sure it
functions properly. Keep this manual and the enclosed
documentation with the machine.
ADDITIONAL SAFETY INSTRUCTIONS
Fig.6
A. Never exceed the maximum load capacity of the
ram. Do not over extend the ram, as it is possible to
force the plunger out of the top of the ram.
B. When coupler valves are disconnected always insert
the dust cap to keep the oil lines clean.
C. If the load is not centered to the ram plunger, pump
carefully. If you have to use excessive pressure to
pump the ram, stop the operation and adjust the set-
up so that the load is more central. This should
decrease the effort required.
D. Do not drop any heavy objects onto the hose, and do
not allow the hose to kink. Always allow clearance
for the hose to avoid damage to the hose and
couplers.
E. Keep the equipment away from heat or fire, as this
may damage or weaken the equipment.
USE
ATTACHMENT COMBINATIONS
Fig.1 - 5
• The pump unit can be used with the multi-directional
ram. (see Fig.1)
• For confined areas the hydraulic spreading wedge
should be used. (see Fig.2)
• Fig.3 shows a few of the many attachment
combinations.
1. Connect the hydraulic ram and pump unit hose
together, ensure you have securely fastened the
couplings before pumping.
2. Firmly close the releast valve by turning it in a
clockwise direction (See Fig .4, A).
3. Apply pressure to the pump by pumping the handle
up and down.
4. To release the pressure turn the valve anti-clockwise
(See Fig .4,B).
The pump can be used in any position, but always
keep the hose end of the pump unit facing
downwards when positioned vertically (See Fig .5).
TROUBLE SHOOTING
1. Pump unit will not work
Dirt on valve seals/Worn seals.
• Replace with new seals.
2. Pump unit will not produce pressure
Air block
• Open the release valve and remove oil filler plug.
The reservoir could be overfilled or low on hydraulic
oil level.
• To check the oil level, remove the filler plug. Top up oil
to correct level.
3. Pump unit feels unsteady under load
Air block.
• Pump handle a couple of full strokes and close the
release valve.
The pump cup seal could be worn out.
• Replace the cup seal with a new one.
4. Pump unit will not lower completely
Air block
• Replace filler plug
• Release air by removing filler plug.
MAINTENANCE
When the body repair kit is not in use, the pump
unit should be stored with the release valve open.
REFILL OIL
Fig.7
• To check the oil level, place the pump unit in an upright
position, as indicated on the diagram. If required add
hydraulic oil until it is level with the full mark.
• Remove the dip stick and the oil level will be
indicated.
• Your jack was filled at the factory with high grade
hydraulic oil. Only use approved oil.
After extensive use, the oil supply should be replaced
to ensure longer equipment life. To drain, remove
the dip stick and open release valve. Ensure that no
dirt gets into the system. Refill with approved oil.
Maintain the tool with care
The tool works best and safest if it is kept clean
Observe the instructions for maintenance and changing
accessories.
