IT IS THE RESPONSIBILITY OF THE EMPLOYER TO PLACE THE INFORMATION IN THIS
FAILURE TO OBSERVE THE FOLLOWING WARNINGS COULD RESULT IN INJURY
PLACING TOOL IN SERVICE
• Always operate, inspect and maintain this tool in accordance with International Standards ISO9001
and ANSI B30.1.
• This tool will function using an air or electric powered hydraulic pump. Adhere to the pump safety
requirements and follow instructions when connecting the pump to the tool.
• Use only equipment rated for the same pressure and torque.
• Use only a hydraulic pump capable of generating 10,000 psig (700 bar) maximum pressure with this
tool.
• Use only twin line hydraulic hose rated for 10,000 psig (700 bar) pressure with this tool.
• Do not interchange the male and female swivel inlets on the tool or the connections on one end of the
hose. Reversing the inlets will reverse the power stroke cycle and may damage the tool.
• Do not use damaged, frayed or deteriorated hoses and fittings. Make certain there are no cracks,
splits or leaks in the hoses.
• Use the quick connect system to attach the hoses to the tool and pump. Make certain the spring-loaded
retaining rings are fully engaged to prevent the connectors from disengaging under pressure.
• When connecting hoses that have not been preloaded with hydraulic oil, make certain the pump reservoir is not
drained of oil during start-up.
• Do not remove any labels. Replace any damaged label.
USING THE TOOL
• Do not handle pressurised hoses. Escaping oil under pressure can penetrate the skin, causing serious injury.
If oil is injected under the skin, see a doctor immediately.
• Never pressurise uncoupled couplers. Only use hydraulic equipment in a coupled system.
• Always wear eye protection when operating or performing maintenance on this tool.
• Always wear head and hand protection and protective clothing when operating this tool.
The use of other than genuine Hi-Force replacement parts may result in safety hazards, decreased tool
performance, and increased maintenance, and may invalidate all warranties.
Repairs should be made only by authorised personnel. Consult your nearest Hi-Force Authorised
Service centre.
