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. Reduce the pressure by turning the knob anticlockwise. The

pressure setting can be locked at the desired value by tightening the wing nut under the adjusting knob clockwise.

The pump is now ready for use

Refer to torque wrench operating instructions for detailed information on the correct operation of these tools.

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.

●

Regularly inspect the air hoses for damage.

●

Oil should be replaced after approximately 500 working hours. Drain oil via drain plug (9)

●

Add viscosity grade 22 air line lubrication oil to reservoir (15) as required. Do not use hydraulic oil.

Drain water from air regulator filter bowl as required by depressing the valve on the bottom of the bowl.
