Read and carefully follow these instructions. Most problems with new equipment are caused by improper operation
or installation. Warning statements must be carefully observed to help prevent personal injury.
:
WARNING
To help avoid personal injury,
Hydraulic Hose
•
Before operating the pump, all hose connections must be tightened with the proper tools. Do not
overtighten. 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.
•
Should a hydraulic hose ever rupture, burst, or need to be disconnected, immediately shut off the pump
and shift the control valve twice to 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 kink, twist, curl, or bend so tightly that the oil flow within the hose is
blocked or reduced. Periodically inspect the hose for wear because any of these conditions can damage
the hose and result in personal injury.
•
Do not use the hose to move attached equipment. Stress may damage the hose and cause personal
injury.
•
Hose material and couple 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. Never paint the couplers. Hose deterioration due to
corrosive materials can result in personal injury.
Pump
•
Do not exceed the PSI 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 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.
