TILT ANGLE ADJUSTMENT
Test Procedure
The following conditions mean the tilt cylinders
need to be adjusted:
a. Tilt the mast fully forward. As the mast is
tilted forward, watch both tilt cylinder
ends. If one end stops before the other,
adjustment is required.
b. Tilt the mast to the full back position. As
the mast is tilted back, watch both of the
tilt cylinder ends. If one cylinder stops
before the other, adjustment is required.
c. Tilt the mast to the full forward position.
Use an angle protractor to measure the
angle of the mast. If the tilt angle does
not match the specifications listed on the
serial plate, both tilt cylinders need
adjustment.
Adjustment
1. Disconnect the rod end from the mast (refer to
TILT CYLINDER Removal procedure in this
section).
2. Loosen the rod end clamp screw (Item 8
Figure 6.1).
3. Rotate the tilt cylinder rod end to adjust the
length of the cylinder.
NOTE
Connect the rod end to the mast and test both
forward and backward tilt after each change
in tilt cylinder length to verify proper
adjustment. Continue adjusting as necessary
until both tilt cylinders stop at the same time
in both the forward and backward tilt, and the
tilt angle is correct.
4. Once proper adjustment is attained, tighten
the clamp screw to lock the rod end.
5. Test the tilt cylinder adjustment per the Test
Procedure above.
RELIEF PRESSURE ADJUSTMENT
Special Tools: P/N 9650041 Pressure Check
Adapter & Hose Kit
1. Locate the pressure check port for the lift
system. This port is on the lift pump outlet
fitting.
2. Connect an appropriate pressure gauge to the
port using the adapter and hose kit.
3
. Place a maximum capacity load on the
carriage. Read the pressure gauge while
lifting in the second stage and record the
highest pressure observed. Continue lifting to
the stops. Record the pressure while lifting
against the stops. DO NOT lift against the
stops for more than 5 seconds.
4. The relief pressure should be approximately
200 psi above the lifting pressure (for a triplex
mast, approximately 2400 psi). Relief
pressure may be adjusted at the relief valve
on top of the manifold. Loosen the lock nut on
the valve and turn the internal screw clockwise
to increase pressure or counter-clockwise to
decrease pressure. When the relief pressure
is correct, tighten the lock nut.
