HYDRAULIC SAFETY PRECAUTIONS
WARNING
General Operatio
n
· All WARNING statements must be carefully observed to help prevent personal injury.
· Before operating the pump, all hose connections must be tightened with the proper tools. Do not over
tighten. Connections should only be tightened securely and leak-free. Over tightening can cause
premature thread failure or high pressure fittings to split at pressures lower than their rated capacities.
· Should a hydraulic hose ever rupture, burst, or need to be disconnected, immediately shut off the
pump and release all pressure. Never attempt to grasp a leaking pressurized hose with your hands.
The force of escaping hydraulic fluid could cause serious injury.
· Do not subject the hose to potential hazard such as fire, sharp surfaces, extreme heat or cold or
heavy impact. Do not allow the hose to be altered or kink, twist, curl, crush, cut, or bend so tightly that
the fluid flow within the hose is blocked or reduced. Periodically inspect the hose for wear, because
any of these condition’s can damage the hose and possibly result in personal injury.
· Do not use the hose to move attached equipment. Stress can damage hose and possibly cause
personal injury.
· Hose material and coupler seals must be compatible with the hydraulic fluid used. Hoses also must
not come in contact with corrosive materials such as creosote-impregnated objects and some paints.
Consult the manufacturer before painting a hose. Hose deterioration due to corrosive materials can
result in personal injury. Never paint the couplers.
· Inspect machine for wear, damage, and correct function before each use. Do not use machinery that
is not in proper working order, but repair or replace it as necessary.
· Replace worn or damaged safety decals.
· Modification of a product requires written Power Team authorization.
· Use only components with the same pressure rating when assembling a system or machine.
Pump
· Do not exceed the hydraulic pressure rating noted on the pump data plate or tamper with the internal
high pressure relief valve. Creating pressure beyond the rated pressure can result in personal injury.
· Before replenishing the fluid level, retract the system to prevent overfilling the pump reservoir. An
overfill can cause personal injury due to excess reservoir pressure create when cylinders are
retracted.
Air Supply
· Shut off and disconnect the air supply when the pump is not in use or before breaking any
connections in the system.
PREPARATION & SET-UP
Air Supply Hook-Up
Remove the thread protector from the air inlet of the pump. Select and install the threaded fittings
which are compatible with your air supply fittings. The air supply should be 20 CFM (.57 M3/min.) and
100 PSI (7 BAR) at the pump to obtain the rated hydraulic pressure. Air pressure should be regulated
to a maximum of 140 PSI (9 BAR). Secure your pump fitting to the air supply.
WARNING: If improperly used, pressurized equipment can be potentially hazardous. Therefore:
· Hydraulic connections must be securely fastened before building pressure in the system.
· Release all system pressure before loosening any hydraulic connection in the system.
Venting the Reservoir
To improve hydraulic fluid delivery and increase useable hydraulic fluid capacity, remove shipping
plug and install filler/vent cap before using the pump.
