Safety Precautions Continued
• High pressure fluid is present throughout a hydraulic system. Always use caution when
operating, repairing, or maintaining this equipment. Before beginning any work on any
hydraulic system component, stop the equipment, disconnect from its power source, and
relieve all pressure in all parts of the system. Do not tamper with the internal hydraulic
relief valve settings.
• Avoid exposing hydraulic equipment (especially hoses) to extreme high or low
temperatures. Damage to equipment or failure may result and cause loss of control or
injury to the operator.
• Exercise caution to avoid the risk of fire.
• Do not drop any hydraulic system components. Damage to the equipment and/or injury
may result.
• Avoid slipping or falling by cleaning up any oil spills.
• Avoid back injury by always lifting equipment carefully.
• It is strongly recommended to view the Power Team Hydraulic Safety video tape before
using hydraulic equipment.
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.
• Always shut off the electric motor before breaking any connections 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 some paints. Consult the manufacturer before painting a hose.
Never paint the couplers. Hose deterioration due to corrosive materials can result in
personal injury.
• Avoid straight line tubing connections in short runs (See Figure 1). Straight line runs do
not provide for expansion and contraction due to pressure and/or temperature changes.
• Eliminate stress in the tube lines. Long tubing runs should be supported by brackets or
clips. Tubes through bulkheads must have bulkhead fittings. This makes easy removal
possible and helps support the tubing.
• Carefully inspect all hoses and fittings prior to use. Before each use, check entire hose
for cuts, leaks, abrasion or bulging of cover, or damage or movement of couplings. If
any of these conditions exist, replace the hose immediately. NEVER attempt to repair
the hose.
