9.5 Clean the Engine Air Filter
IMPORTANT! Operating the engine without an air filter, or
with a damaged air filter, can allow dirt to enter the engine,
causing rapid engine wear. This type of damage is not
covered by warranty.
Clean the air filter after every 200 hours of operation or
annually.
A dirty air filter can restrict air flow to the carburetor, reducing
the engine performance. If the engine is operated in very dusty
areas, clean the air filter more often than specified
.

Loosen the two air-filter cover fasteners.
2.
Remove the cover.
3.

4.
Gently tap the air filter on a hard surface to loosen and
remove dust and debris.

9.6 Replace the Drive Belt
IMPORTANT! After the drive belt is replaced, set the
correct tension, and align the engine and rotor sheave.
Check the drive belt tension after every 100 hours of
operation.
The machine has a centrifugal clutch mounted on the engine
shaft that drives the rotor sheave. When the drive belt is loose or
in disrepair, the ability of the engine to efficiently drive the rotor
may be affected. Therefore, it is important to check the drive
belt condition and tension on a regular basis. Replace the drive
belt if it is frayed, cracked, or worn.
1.
Set the machine to a safe condition.
For instructions, see
.
2.
On the side of the machine, remove the drive-belt guard.
3.
Loosen (do not remove) the four engine mount bolts (two
on each side).
4.
Turn the belt tensioning bolt counterclockwise to loosen the
drive belt tension.
5.
Loosen the tension until you can slide the engine back and
remove the belt.
6.
Install the new drive belt, and then slide the engine forward.
