Procedure for Installing Hydraulic Fittings
and Hoses
NOTE: Overtightening JIC hose
fi
tting ends will
result in a fractured
fi
tting.
DO NOT
use thread sealant/tape on hoses or
fi
ttings.
These materials could damage the product. Always
use two wrenches to ensure proper tightening of
fi
ttings and hoses.
Use the following procedure to install SAE O-ring
fi
ttings in valve block and rams:
1. Turn jam nut on
fi
tting as far back as possible.
2. Lubricate O-ring with clean hydraulic
fl
uid.
3. Screw
fi
tting into port by hand until the washer
contacts port face and shoulder of the jam nut
threads.
4. Unscrew
the
fi
tting to proper position; no more
than one full turn.
5. Using two wrenches, hold
fi
tting body in position
and tighten jam nut until the washer again
contacts port face, then tighten an additional
1/8–1/4 turn to lock
fi
tting in place. Final torque on
the jam nut should be approximately 20 ft-lb.
Use the following procedure to install hydraulic
hoses:
1. Screw
fl
are nut onto
fi
tting
fl
are and hand tighten.
2. Align hose so there are no twists or sharp bends
and so it will not be pinched or pulled by moving
parts.

WARNING
Lower blade when vehicle is parked. Keep
8' clear of blade drop zone. Temperature
changes could change hydraulic pressure,
causing the blade to drop unexpectedly or
damaging hydraulic components. Failure to
do this can result in serious personal injury.
WARNING
Keep 8' clear of the blade drop zone when it is
being raised, lowered, or angled. Do not stand
between the vehicle and blade or directly in
front of blade. If the blade hits you or drops
