There is a simplified start reminder (with

illustrations to describe each step) loc-

ated on the back of the blower.

STARTING A WARM ENGINE

1. Move the choke lever to the HALF CHOKE

position.

2. Squeeze the throttle trigger fully and hold

through

all remaining steps.

3. Pull starter rope sharply until engine runs,

but no more than 6 pulls.

4. Allow engine to run 15 seconds, then move

the choke lever to RUN.

NOTE:

If engine has not started, pull starter

rope 5 more pulls. If engine still does not run, it

is probably flooded.

STARTING A FLOODED ENGINE

Flooded engines can be started by placing the

choke lever in the RUN position; then, pull the

rope to clear the engine of excess fuel. This

could require pulling the starter handle many

times depending on how badly the unit is

flooded. If the unit still doesn’t start, refer to

TROUBLESHOOTING TABLE.

unless engine and muffler are cold. A hot

muffler can cause serious burns.

loose or damaged parts. Clean the unit and

decals using a damp cloth with a mild deter-

gent.

S

Wipe off unit with a clean dry cloth.

CLEAN AIR FILTER

Air Filter

Cover

Air Filter

Button

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.

NOTE:

Move choke lever to RUN position

before opening air filter cover.

2. Remove parts as illustrated.

NOTE:

Do not clean filter in gasoline or

other flammable solvent. Doing so can

create a fire hazard or produce harmful

evaporative emissions.

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.

REPLACE FUEL FILTER

To replace fuel filter, drain unit by running it dry of

fuel, then remove fuel cap/retainer assembly

from tank. Pull filter from tank and remove it from

fuel line. Install new fuel filter on fuel line; reinstall

parts.
