• Do not over-tighten the connections. Connections
need only be tightened securely and leak-free.
Over-torque may cause premature thread failure and
may cause high pressure fittings to split at pressures
lower than their rated capacities.
• Do not subject the hose to any potential hazard
such as fire, extreme heat or cold, heavy impact or
sharp surfaces. Do not use the hose to lift or
move the equipment connected to it.. Might rupture
or weaken the hose.
• Periodically inspect the hose for signs of wear.
Never use a defective hose with any pressurized
equipment. Escaping hydraulic fluid could cause seri-
ous injury.
• Never paint the couplers, fittings or hose. Make
sure that the hose material and coupler seals are
compatible with the hydraulic fluid used. Avoid
contact with creosote-saturated materials. May
result in hose damage and leaking of hydraulic fluid.

Hydraulic Pump

• Never exceed the rated capacity of the unit. Never
tamper with the internal high pressure relief valve.
May result in pump failure.
• Always retract the system before replenishing the
oil level. Never over-fill the pump reservoir with oil.
Could damage the pump.

Hydraulic Cylinder

• Keep the cylinder clean at all times. Keep the pis-
ton fully retracted when the cylinder is not in use.
Prevents damaging the cylinder.
• Make certain that the hydraulic fluid added to the
system is compatible with the seals and the exist-
ing fluid. Never use brake fluid. May result in leaking
of the hydraulic fluid.
