SPARK ARRESTER (applicable types)
In Europe and other countries where the machinery directive 2006/42/EC
is enforced, this cleaning should be done by your servicing dealer.
The spark arrester may be standard or an optional part, depending on the
engine type. In some areas, it is illegal to operate an engine without a
spark arrester. Check local laws and regulations. A spark arrester is
available from authorized Honda servicing dealers.
The spark arrester must be serviced every 100 hours to keep it
functioning as designed.
If the engine has been running, the muffler will be hot. Allow it to cool
before servicing the spark arrester.
Spark Arrester Removal
1. Remove the two 8 mm nuts and remove the muffler from the
cylinder.
2. Remove the three 4 mm screws from the exhaust deflector, and
remove the deflector.
3. Remove the 6 mm screw and four 5 mm screws from the muffler
protector and remove the muffler protector.
4. Remove the two 5 mm screws from the spark arrester, and remove
the spark arrester from the muffler.

Spark Arrester Cleaning & Inspection
1. Use a brush to remove carbon deposits from
the spark arrester screen. Be careful not to
damage the screen. Replace the spark
arrester if it has breaks or holes.
2. Install the spark arrester, muffler protector,
exhaust deflector and muffler in the reverse
order of disassembly.

HELPFUL TIPS & SUGGESTIONS
STORING YOUR ENGINE
Storage Preparation
Proper storage preparation is essential for keeping your engine trouble-
free and looking good. The following steps will help to keep rust and
corrosion from impairing your engine's function and appearance, and
will make the engine easier to start when you use it again.
Cleaning
If the engine has been running, allow it to cool for at least half an hour
before cleaning. Clean all exterior surfaces, touch up any damaged paint,
and coat other areas that may rust with a light film of oil.
Using a garden hose or pressure washing equipment can force water into the
air cleaner or muffler opening. Water in the air cleaner will soak the air filter,
and water that passes through the air filter or muffler can enter the cylinder,
causing damage.
Fuel
Depending on the region where you operate your equipment, fuel
formulations may deteriorate and oxidize rapidly. Fuel deterioration and
oxidation can occur in as little as 30 days and may cause damage to the
carburetor and/or fuel system. Please check with your servicing dealer for
local storage recommendations.
Gasoline will oxidize and deteriorate in storage. Deteriorated gasoline
will cause hard starting, and it leaves gum deposits that clog the fuel
system. If the gasoline in your engine deteriorates during storage, you
may need to have the carburetor and other fuel system components
serviced or replaced.
The length of time that gasoline can be left in your fuel tank and
carburetor without causing functional problems will vary with such
factors as gasoline blend, your storage temperatures, and whether the
fuel tank is partially or completely filled. The air in a partially filled fuel
tank promotes fuel deterioration. Very warm storage temperatures
accelerate fuel deterioration. Fuel deterioration problems may occur
within a few months, or even less if the gasoline was not fresh when you
filled the fuel tank.
Fuel system damage or engine performance problems resulting from
neglected storage preparation are not covered under the Distributor's
Limited Warranty.
You can extend fuel storage life by adding a gasoline stabilizer that is
formulated for that purpose, or you can avoid fuel deterioration
problems by draining the fuel tank and carburetor.
Adding a Gasoline Stabilizer to Extend Fuel Storage Life
When adding a gasoline stabilizer, fill the fuel tank with fresh gasoline. If
only partially filled, air in the tank will promote fuel deterioration during
storage. If you keep a container of gasoline for refueling, be sure that it
contains only fresh gasoline.
1. Add gasoline stabilizer following the manufacturer's instructions.
2. After adding a gasoline stabilizer, run the engine outdoors for 10
minutes to be sure that treated gasoline has replaced the untreated
gasoline in the carburetor.
3. Stop the engine.
