3. Raise the boom to specified angle A (Figure 4-1
) while
monitoring the angle on the mechanical indicator or on
the operating conditions screen of the front-console
display.
4. Verify that the boom is at proper angle A:
a. Place an accurate digital level (12) on the boom butt
as shown in Figure 4-3
. The corresponding Digital
Level Angle should appear on the digital level.
b. Raise or lower the boom as necessary.
5. If the boom stops at the specified angle, further
adjustment is not needed.
a. If the boom stops before reaching the specified
angle, go to step 6.

switch as shown in View A.
9. To test the adjustment, using the following procedure:
a. Lower the boom several degrees below specified
angle A.
b. Slowly raise the boom.
c. The boom must stop at specified angle A. If the
boom does not stop at the specified angle, use the
following procedure:
- Stop raising the boom (move the control handle
to OFF).
- Lower the boom several degrees below the
specified angle.

ACTUATOR ROD REPLACEMENT
See Figure 4-2, View B for the following procedure:
