High pressure hydraulics [oil under 2450 psi (16,893 kPa)] used to operate
this equipment can pierce body tissue and cause severe injury to personnel.
Never disconnect any hydraulic line or fitting without first dropping
pressure to zero.
Wear safety goggles when performing leakage tests on valves. Failure to
do so may result in serious eye injury due to high pressure oil.
To keep dirt from contaminating fluid systems when removing and installing lines, perform the
Clean fittings and surrounding area before disconnecting lines.
Cover, cap, plug, or tape lines and ports after disconnecting lines. Use cap and plug set on
air lines. When these are not available, use hand-carved wooden plugs, clean rags (item
from entering system.
Ensure that new and used parts are clean before installing.
Wait to remove covers, caps, plugs, or tape from lines and ports until just before installing
Apply anti-seize tape only to pipe threads of male fittings of air system or
damage to air valves may result.
When connecting air lines and fittings without compression sleeves or packings, anti-seize
tape (item 21, Appendix F) may be used to keep connections from leaking. Use as follows:
Ensure that threads are clean and dry.
Start anti-seize tape one or two threads from small or leading edge of fitting, joining tape
together with an overlap of about 1/8 in. (3.18 mm) for fittings with fine threads. For fittings
with coarse threads, tape should be wrapped around threads two or three times.
Tightly wrap anti-seize tape in same direction as you would tighten a nut. Tape must be
pressed into threads without cutting or ripping.
DO NOT exceed specified torque or use power tools to tighten fittings taped
with antis-eize tape. Over tightening could damage fitting threads and cause
connection to leak.
Using hand tools, tighten fittings to specified torque.
