Adjusting the Control Cable, Checking the Cable

Adjusting the Control Cable

Checking the Cable

Service Interval: After the first hour

Yearly—Check the control cable and adjust it if necessary.

Important: Check the control cable for proper adjustment initially, after the first 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.

Figure 19

1.1/16 to 1/8 inch (2 to 3 mm) gap

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-fitting 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-fitting 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.
