IT IS THE RESPONSIBILITY OF THE EMPLOYER TO PLACE THE INFORMATION IN THIS
MANUAL INTO THE HANDS OF THE OPERATOR.
FAILURE TO OBSERVE THE FOLLOWING WARNINGS COULD RESULT IN INJURY.
PLACING TOOL IN SERVICE
• Always operate, inspect and maintain this tool in
accordance with American National Standards Safety
Code for Hydraulic Rams and Jacks (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 (681 bar) maximum pressure with this tool.
• Use only twin line hydraulic hose rated for 10,000 psig
(681 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 and the safety rings are tightly
threaded against the spring-loaded retaining rings 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 labels.
USING THE TOOL
• Do not handle pressurized hoses. Escaping oil under
pressure can penetrate the skin, causing serious injury. If
oil is injected under the skin, see a doctor immediately.
• Never pressurize 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 replacement parts may result in safety hazards, decreased tool performance, and
increased maintenance, and may invalidate all warranties.
