Hi-Force will not always be aware of what equipment this pump will be used with. It is the responsibility of
the owner and all operators to read, understand and comply with all appropriate safety warnings and
operating instructions relating to the equipment used.
NOTE: Every pump is factory-fitted with an adjustable pressure relief valve. The valve is factory set to the
maximum working pressure of the pump model specified.
This valve can be adjusted by the customer, to any desired pressure within the rating of the pump.
Details for the method of adjustment for this valve are available on request.
IMPORTANT:
Before use, make sure the reservoir has sufficient capacity for the required operation.
Make sure the fluid level does not drop below the minimum operating level, as this may
cause air to be pumped into the system. Fluid levels can be checked using the dipstick
attached to the reservoir filler cap (4).
Single acting pumps:
Turn the pressure release valve (7) clockwise to close it.
Pressurise the system by operating the pump handle (2)
Release the system pressure by slowly opening the pressure release valve (7) anti-clockwise.
(See figure 5.1)
IMPORTANT:
After operation, fully return all hydraulic fluid to the pump. Monitor the hydraulic fluid level in
the reservoir to prevent over-filling of the tank.
7.0 Operation
NEVER set the pressure relief valve above the rated maximum working
pressure of the pump (as displayed on the identification plate) or above the
maximum pressure for the system.
Only use the pump handle supplied. DO NOT use handle extensions.
NEVER jerk the handle during operation. This makes the pump inefficient and
can cause unexpected over pressurisation. A smooth, steady action, using full
stroke produces the best results and will reduce operator fatigue.
