Hydraulic Hose Installation
Hold the fixed portion of the hose coupling with one
wrench; use a second wrench to tighten or loosen the
hose nut. This will avoid damaging the fitting seal. When
tightening a hose, do not permit the hose to twist; hold
the hose in a normal straight position.
When installing hoses, place fittings at angles to avoid
contact with fixed parts when turning. Make sure hoses
are assembled to proper “A” and “B” ports on
components.
