HYDRAULIC FITTINGS

Do not use thread sealant/tape on hoses and fi ttings.
This could damage the product. Install all fi ttings into
rams and hydraulic unit using the following procedure
and fi tting orientation illustrations:
1. Remove the plug from ram or manifold port. Use
a rag to catch residual fl uid when removing the
manifold plugs.
2. Turn the jam nut on the fi tting as far back as
possible.
3. Lubricate the O-ring with clean hydraulic fl uid.

Fitting
For blades built after March 2, 2010, these fittings
are pre-installed and the cylinders are pre-filled
with hydraulic fluid. The build date can be found in
the first six digits of the serial number, located in
the upper right corner on the back of the blade
(YYMMDD: YY = 2-digit year, MM = 2-digit month,
DD = 2-digit day).

4. Install the hexagonal orifi ce plate under each of
the two wing rod fi ttings as shown below. The
slot in the orifi ce plate must face the manifold.
Installing the orifi ce plates backwards will cause
blade wings to "chatter" when retracting.
5. Screw the fi tting into the port by hand as far as it
will go. The washer should contact the port face
and shoulder of the jam nut threads.
6. Unscrew the fi tting to proper position, no more
than one full turn.
7.
Use one wrench to hold the fi tting body in position
and tighten the jam nut with another wrench until
the washer again contacts the port face. Tighten
1/8–1/4 turn to lock the fi tting in place.
