Adjusting the Control Cable
Checking the Cable
Service Interval: After the rst hour
Yearly—Check the control cable and
adjust it if necessary.
Important: Check the control cable for proper
adjustment initially, after the rst operating hour,
and then annually thereafter.
1. Move the control bar back toward the handle to
remove the slack in the cable.
2. Ensure that a 1/16 to 1/8 inch (2 to 3 mm) gap exists
between the control bar and the handle (Figure 19).
To adjust the cable, refer to Adjusting the Cable
below.

Important: The control cable must contain
some slack when you disengage the control bar
for the rotor blades to stop properly.
Adjusting the Cable
1. Unhook the end of the control cable spring from the
control bar (Figure 20).
Figure 20
2. Move the Z-tting to a higher or lower hole on the
adjuster link as needed to obtain the 1/16 to 1/8
inch (2 to 3 mm) gap between the control bar and
the handle (Figure 21).

Note: Moving the Z-tting higher decreases the
gap between the control bar and the handle; moving
it lower increases the gap.
3. Replace the spring cover and hook the end of the
control cable into the bottom hole of the control bar.
4. Check the adjustment; refer to Checking the Cable.
Note: After extended use, the drive belt may wear
and lose its proper belt tension. If the drive belt slips
(continuously squeals) under a heavy load, increase the
belt tension by inserting the spring end into the top hole
of the control bar. The belt may slip (squeal) in wet
conditions; to dry out the drive system, start the rotor
and run it without a load for 30 seconds.
