ECO:-
Using the key on the end of the operating lever, turn release valve screw clockwise to
close. Do not use excessive force.
Operate the pump to expand the wedge.
Insert a safety block into the gap and then with the key on the end of the operating lever
turn the release valve screw anti-clockwise to open i.e. release hydraulic pressure. So the
gap is held open by the safety block whenever it is required to work within the opened
space. Do not rely on hydraulic means to keep a gap open.
Keep fingers and other body parts clear of closing gaps as the wedge contracts.
When it is necessary to increase the spreading capacity of the tool, one or two stepped
blocks can be added as required (one each side as shown in the diagram). Attach the
stepped blocks with fixing screws as shown.
Note: in certain circumstances when the hydraulic pressure is released and the tool is
under external load, the tool will not retract. A gentle blow on the side of the wedge from a
soft mallet is usually enough to free up the tool. If this occurs repeatedly it may be that the
wedge is un-lubricated or possibly has been damaged in use.
CARE AND MAINTENANCE
Before each use fully expand the tool and grease the exposed protruding wedge surfaces
with molybdenum disulphide grease. This will help to ensure smooth operation and
prolong the life of the tool.
Always use genuine Hi-Force hydraulic oil. The use of other fluids may invalidate your
warranty.
After use, always fully retract the tool.
Protect tools from the elements when not in use. If storing for prolonged periods, grease
exposed metal parts. Never store the tool in an expanded condition.
To protect your warranty, have your cylinder serviced and repaired by an authorised Hi-
Force repairer. Only use genuine Hi-Force spare parts. Spare parts sheets can be
