MAINTENANCE
Spark Arrestor
The exhaust pipe must be period-
ically purged of accumulated car-
bon as follows:
1. Remove the clean out plugs
located on the bottom of the
muffler as shown above.
2. Place the transmission in
neutral and start the engine.
Purge accumulated carbon
from the system by momen-
tarily revving the engine sev-
eral times.
3. If some carbon is expelled, cover the exhaust outlet and rap on the pipe around
the clean out plugs while revving the engine several more times.
4. If particles are still suspected to be in the muffler, back the machine onto an in-
cline so the rear of the machine is one foot higher than the front. Set the parking
brake and block the wheels. Make sure the machine is in neutral and repeat
steps 2 and 3. WARNING: SEE BELOW.
5. If particles are still suspected to be in the muffler, drive the machine onto the
incline so the front of the machine is one foot higher than the rear. Set the park-
ing brake and block the wheels. Make sure the machine is in neutral and repeat
steps 2 and 3. WARNING: SEE BELOW.
6. Repeat steps 2 through 5 until no more particles are expelled when the engine
is revved.
7. Stop the engine and allow the arrestor to cool.
8. Reinstall the arrestor plugs.
WARNING
D Because exhaust system temperatures can reach 1000°F, do not perform
this operation immediately after the engine has been run because the ex-
haust system becomes very hot.
D Because of the increased fire hazard, make sure that there are no com-
bustible materials in the area when purging the spark arrestor.
D Wear eye protection.
D Do not stand behind or in front of the vehicle while purging the carbon from
the spark arrestor.
D Never run the engine in an enclosed area. The exhaust contains poison-
ous carbon monoxide gas.
D Do not go under the machine while it is inclined.
Failure to heed these warnings could result in serious personal injury or death.
