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