To prevent personal injury, follow the guidelines below. Follow the manufacturer's recommendations when connecting this unit to hydraulic cylinders, hydraulic pullers or other attachments.
Hydraulic Hose
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. Overtightening can cause premature thread failure or high pressure fittings to split at pressures lower than their rated capacities.Always shut off the electric motor before breaking any connection in the system.Should a hydraulic hose ever rupture, burst or need to be disconnected, immediately shut off the pump. 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 let the hose kink, twist, curl or bend so tightly that oil flow within the hose is blocked or reduced. Periodically inspect the hose for wear, because any of these conditions can damage the hose.Do not use the hose to move attached equipment. Stress can damage the hose, causing 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 certain paints. Consult the manufacturer before painting a hose. Never paint the couplers. Hose deterioration due to corrosive materials can result in personal injury.Pump
Do not exceed the hydraulic pressure rating noted on the pump nameplate or tamper with the internal high pressure relief valve. Creating pressure beyond rated capacities can result in personal injury.Before replenishing the oil level, retract the system to prevent overfilling the pump reservoir. An overfill can cause personal injury due to excess reservoir pressure created when cylinders are retracted.Cylinder
Do not exceed the rated capacities of the cylinders. Excess pressure can result in personal injury.Do not set poorly balanced or off-center loads on a cylinder. The load can tip and cause personal injury.Power Supply (Electric)
Never use an ungrounded power supply with this unit.The pump must be compatible with existing line voltage.Disconnect the pump from the power supply when performing maintenance or repair on the unit.If the unit's power supply is damaged or the inner wiring is exposed in any way, replace immediately.Any electrical work must be done by a qualified electrician.If the power cord is damaged or wiring is exposed, replace or repair immediately.Changing the voltage on the jet motor (single or three phase) is a complicated and, if not done correctly, dangerous procedure.
