1/8-inch (2 mm to 3 mm) gap between the control
bar and the handle (Figure 25).
Note:
Moving the Z-fitting higher decreases the
gap between the control bar and the handle; moving
it lower increases the gap.
3. Hook the spring to the adjuster link and slide the
spring cover over the adjuster link.
4. Check the adjustment; refer to Checking the Control
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,
disconnect the spring from the adjustor link and
move the upper end of the spring to the hole that
is further from the pivot point in the control bar
(Figure 27). Then connect the spring to the adjustor
link and adjust the control cable.

Note:
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.
Inspecting the Rotor Blades
Service Interval:
Yearly—Inspect the rotor blades and
have an Authorized Service Dealer
replace the rotor blades and scraper if
necessary.
Before each session, inspect the rotor blades for wear.
When a rotor blade edge has worn down to the wear
indicator hole, have an Authorized Service Dealer
replace the rotor blades and the scraper (Figure 28).

The wear indicator hole is
intact; you do not need to
replace the rotor blades.

The wear indicator hole is
exposed; replace the rotor
blades.
Changing the Engine Oil
Service Interval:
After the first 2 hours
Yearly
Run the engine a few minutes before changing the oil
to warm it. Warm oil flows better and carries more
contaminants.
1. Siphon the fuel from the fuel tank into an approved
fuel container, or run the engine until it stops.
2. Move the machine to a level surface.
3. Place an oil drain pan under the oil drain plug,
remove the oil drain plug, and tip the machine
backward and drain the used oil in the oil drain pan
Figure 29).
Figure 29
4. After draining the used oil, return the machine to the
operating position.
5. Install the oil drain plug and tighten it securely.
6. Clean around the oil fill cap (Figure 30).
