pump
3.2
Hydraulic Hoses & Fluid Transmission Lines
Avoid short runs of straight line tubing. Straight line runs do not provide for expansion
and contraction due to pressure and/or temperature changes
Reduce stress in tube lines. Long tubing runs should be supported by brackets or clips.
Before operating the power unit, connections should be tightened securely and leak-
free. Over tightening can cause premature thread failure or high pressure fittings to
burst
Should a hydraulic hose ever rupture, burst or need to be disconnected, immediately
shut off the power unit and release all pressure. Never attempt to grasp a leaking
pressurised hose with your hands. The force of escaping hydraulic fluid can inflict
injury
Do NOT
subject the hose to potential hazard such as fire, sharp objects, extreme heat
or cold or heavy impact
Do NOT
allow the hose to 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
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 battery acid,
creosote-impregnated objects and wet paint. Never paint a coupler or hose
FAILURE TO HEED THESE WARNINGS MAY RESULT IN PERSONAL INJURY AS WELL AS PROPERTY DAMAGE.

Installation
IMPORTANT:
Always secure threaded port connections with high grade, non-hardening pipe thread
sealant. Teflon tape can be used if only one layer of tape is used and it is applied
carefully, two threads back, to prevent the tape from being introduced into hydraulic
system, which could cause jamming of precision-fit parts
To extend the life of your power unit, the air compressor should have a filter, regulator
and lubricator system that will provide clean, lubricated air to the power unit. Contact
a Durapac representative for the necessary accessories
