A dirty air filter decreases engine perform-

ance and increases fuel consumption and

harmful emissions. Always clean after every

5 hours of operation or yearly, whichever

comes first.

1. Clean the cover and the area around it to

keep debris from falling into the carburetor

chamber when the cover is removed.

2. Press button to open air filter cover. Re-

move air filter.

NOTE:

Do not clean filter in gasoline or other

flammable solvent. Doing so can create a fire

hazard or produce harmful evaporative emis-

sions.

3. Wash the filter in soap and water.

4. Allow filter to dry.

5. Apply a few drops of oil to the filter;

squeeze filter to distribute oil.

6. Replace parts.

REPLACE SPARK PLUG

Replace spark plug each year to ensure the

engine starts easier and runs better. Set

spark plug gap at 0.6 mm. Ignition timing is

fixed, nonadjustable.

1. Twist, then pull off spark plug boot.

2. Remove spark plug from cylinder and dis-

card.

3. Replace with Champion RCJ-6Y spark

plug and tighten securely with a 19 mm

socket wrench.

4. Reinstall the spark plug boot.

CARBURETOR ADJUSTMENTS

There is no screw for idle adjustment on your

blower. The throttle lever is used to control en-

gine speed. The engine speed can be ad-

justed by moving the throttle lever to the left

for low speed or right for high speed. If your

engine will not run properly or you require fur-

ther assistance, contact an authorized ser-

vice dealer.
