SPARK ARRESTER

In a dry or wooded area, it is recommendable to use the engine with a spark arrester.

Some areas require the use of a spark arrester. Please check your local laws and

regulations before operating your engine.

The spark arrester must be cleaned regularly to keep it functioning as designed.

A clogged spark arrester :

● Prevents the flow of exhaust gas

● Reduces engine output

● Increases fuel consumption

● Makes starting difficult

If the engine has been running, the muffler and the spark arrester will be very hot.

Allow the muffler to cool before cleaning the spark arrester.

How to remove the spark arrester

1. Remove the flange bolts from the

MUFFLER

muffler cover and remove the muffler

cover.

2. Remove the special screw from the

spark arrester and remove the spark

arrester from the muffler.

from the spark arrester screen.

Be careful to avoid damaging the screen.

The spark arrester must be free of

breaks and holes. Replace the spark

arrester if it is damaged.

Install the spark arrester, and muffler

protector in the reverse order of

disassembly.

ening the drain screw on the carburetor

float chamber , or run the engine at

no-load until it stops.

■

Disconnect the terminal of the battery.
