A hydraulic pump is required to operate the cylinder range covered in these instructions. Please refer to the

relevant 'Hi-Force hydraulic pump operating instructions' for full details of the chosen pumps applicable

operating instructions.

Single-acting cylinders have 2-different methods of return of the piston. They are either spring-assisted

return or load-assisted return. HVL cylinders are load-assisted return.

Operating Orientation



Hi-Force HVL cylinders can operate in any orientation.

When lowering loads, the load may descend faster than expected. For precise lowering

control, Hi-Force recommends the use of a manual check valve (HM1C).

ALWAYS ensure the cylinders piston contacts the load to be lifted as squarely as

possible.

NEVER extend any HVL cylinder unless its base is fully supported and an external load

is present.

Carry out basic maintenance on a regular basis to keep the cylinder operating in a trouble-free manner.

Maintenance intervals are determined by the frequency of use and the operating conditions on site.



ALWAYS use Hi-Force specified hydraulic oil grades with the cylinders. The use of other fluids may

invalidate your warranty.



After use, always retract the cylinder/s fully before disconnecting the hose/s.



Fit dust caps (5) to the couplers, every time disconnections are made.



Regularly inspect (before and after every use) the cylinder and all accessories for damage.



Inspect the cylinder periodically for paint damage. Clean and touch up any exposed surfaces to

prevent corrosion.



Inspect hoses regularly for damage and wear. DO NOT use hoses that are frayed, abraded or

leaking.



Make sure the cylinder is clean before placing it into storage. Remove any dirt or debris which may

have been picked up while on site.



Store the cylinder/s in a clean and dry environment.



If storage is to be for a prolonged period, it is advisable to apply grease to exposed metal surfaces.



NEVER store, transport or lift a cylinder with its piston in the extended position.
