Inspection Procedure: A tape measure or digital caliper, calibrated click-type torque wrench rated for
150 foot-pounds, 15/16" socket, and paint pen for torque marks are required for this inspection. A second
person may be required to hold tension on the winch line when operating the winch. Read and understand
all steps of the instructions before beginning the procedure.
1. Position the unit on a level surface, apply the parking brake, and turn off the engine. Remove the key
from the ignition, and secure it following your employer’s vehicle lockout/tagout procedure. Chock
the wheels.
2. Locate the planetary winch mounted on the back of the turntable (refer to Figure 1).
3. Determine if any one of the eight cap screws in the winch mounting bracket can be removed without
interfering with the rope on the winch drum (refer to Figure 2).
a. If there is sufficient clearance to remove a cap screw, proceed to step 7.
b. If there is not sufficient clearance to remove a cap screw, proceed to step 4.

4. Start the engine, and engage the power takeoff (PTO). Properly set the outriggers.
5. If there is sufficient space to operate the boom, raise and extend the boom while paying out the winch
line. Otherwise, raise the boom slightly out of the boom rest, and pay out the winch line while a second
person keeps tension on the winch line below the boom tip. Stop when enough winch line is removed
to allow access for removing the cap screw.
6. Disengage the PTO, and turn off the engine.
7. Remove one of the cap screws in the winch mounting bracket.
8. Measure the length of the cap screw (refer to Figure 3). The proper length is 11/2".
• If the cap screw length measures 11/2", reinstall it with the original washer, torque it to 150 footpounds, and mark the head with a torque stripe.
• If the cap screw length measures 11/4", reinstall it with the original washer but leave it loose.

9. If the winch line did not need to be payed out before removing the cap screw, proceed to step 12.
10. Start the engine, and engage the PTO. If the boom was extended in step 5, retract the boom while
paying in the winch line. Otherwise, pay in the winch line while a second person keeps tension on the
winch line below the boom tip. Stop when the boom is fully retracted and the end of the winch line
has reached the boom tip.
11. Stow the boom, retract the outriggers, disengage the PTO, and turn off the engine.
12. Review the inspection result from step 8.
a. If the cap screw length measured 11/4", proceed to step 13.
b. If the cap screw length measured 11/2", proceed to step 14.
13. If the cap screw length measured 11/4", repair is required.
