Adjusting the Rotor Control
Cable
Check the rotor control cable for proper adjustment
initially, after the first operating hour, and then annually
thereafter.
Checking the Rotor Control Cable
1. Stop the engine and wait for all moving parts to stop.
2. Move the control bar back toward the handle until you
remove the slack in the cable (Fig. 8).

3. Ensure that a 1/8 to 1/4 in. (3 to 6 mm) gap exists
between the control bar bracket and the handle as
shown in Figure 9.

Important
The rotor control cable must have slack in it
when you disengage the control bar in order for the rotor
blades to stop properly.
Adjusting the Rotor Control Cable
1. Unhook the spring end from the hole in the center of the
control bar bracket as shown in Figure 10.

2. Slide the spring cover up the cable adjuster.
3. Unhook the Z-fitting from the cable adjuster (Fig. 10),
and position it in a different hole on the adjuster to
obtain a gap of 1/8 to 1/4 inch (3 to 6 mm) between the
control bar bracket and the handle (Fig. 9).
Note: Moving the Z-fitting to a hole closer to the spring
decreases the gap between the control bar bracket and
the handle; moving it to a hole farther from the spring
increases the gap.
4. Install the spring cover over the cable adjuster.
5. Hook the spring end into the hole in the center of the
control bar bracket as shown in Figure 10.
6. Check the adjustment (refer to Checking the Rotor
Control Cable on page 12).
Note: After extended use, the drive belt may wear and lose
its proper belt tension. Improper belt tension causes the belt
to slip and decreases the performance under a heavy load.
Belt slippage may occur after two or three seasons of
normal usage (10 to 15 operating hours). If the drive belt
slips (continuously squeals) under a heavy load, increase
the belt tension by positioning the spring end in the other
hole in the control bar bracket as shown in Figure 10.
Adjust the gap between the control bar bracket and the
handle to 1/8 to 1/4 in. (3 to 6 mm).
Note: Using the incorrect hole in the control bar bracket
can reduce the drive belt life. Occasional belt slippage
(squealing) may occur in extremely wet conditions due to
moisture in the drive system. To remove moisture, start the
rotor and operate it without a load for 30 seconds. Once
you remove the moisture, the drive belt should not slip.
