SAFETY
READ THIS MANUAL BEFORE OPERATING THE TOOL. FAILURE TO OBSERVE THE
FOLLOWING WARNINGS COULD RESULT IN SERIOUS BODILY INJURY.
●
Ensure that all equipment connected to the pump is in good condition and is all rated for
700 bar operating pressure.
●
Always stand the pump on a stable level surface during operation.
●
Never invert the pump or lay it on its side either in use, transport or in storage.

Always use eye, ear and hand protective equipment when using this pump and
associated equipment.
●
Isolate the pump from the electrical supply when carrying out maintenance or

    Remove the cap (3) from the oil filler. Stand the pump on a level surface and fill the tank via the filler breather (3) with Hi-force HFO46 oil until the oil level is at the maximum level as shown on the level gauge. N.B more oil can be added if desired to assist cooling but never to more than 25mm below the tank lid.

  • Page 4: Initial Operation

    NB if very long hoses are employed (greater than 5 m) then this method will not be totally effective. Consult your Hi-Force distributor for advice on pre-filling hoses. Press and hold the advance button again and whilst doing so adjust the relief valve by turning the knob clockwise until maximum working pressure (700 bar) is reached.

  • Page 5: Maintenance

    The oil level in the reservoir should not be allowed to fall below the minimum level during use. Keep the reservoir topped up with Hi-Force HFO46 oil. If the oil level does fall below the minimum level then air may be drawn into the system and cause erratic operation.
