WARNING: If any adjustments are made
to the engine while the engine is running
(e.g. carburetor), keep clear of all moving
parts. Be careful of heated surfaces and
muffler.
Minor carburetor adjustment may be required to com­
pensate for differences in fuel, temperature, altitude
or load.
NOTE: A dirty air cieaner will cause engine to run
rough. Be certain air cleaner is clean and attached to
the carburetor before adjusting carburetor.
Do not make unnecessary adjustments. Factory set­
tings are satisfactory for most applications and condi­
tions. If adjustment is needed, refer to the separate
engine manual packed with your leaf blower.

connect spark plug wire before cleaning,

LUBRICATION
Wheels-Rear wheels are provided with light oil bear­
ings. Place a few drops of SAE 30 oil on each bearing
once a season.
Directional Discharge-Lubricate the spring and the
pivot point on the door mechanism at least once a
season with light oil.
ENGINE
Refer to the separate engine manual for engine
maintenance instructions.
Maintain engine oil as instructed in the separate
engine manual packed with your unit. Read and follow
instructions carefully.
Service air cleaner every 25 hours under normal con­
ditions. Clean every few hours under extremely dusty
conditions. Poor engine performance and flooding
usually indicates that the air cleaner should be ser­
viced. To service the air cleaner, refer to the separate
engine manual packed with your unit.
The spark plug should be cleaned and the gap reset
once a season. Spark plug replacement is recom­
mended at the start of each season; check engine
manual for correct plug type and gap specifications.
Clean the engine regularly with a cloth or brush.
Keep the cooling system (blower housing area) clean
to permit proper air circulation which is essential to
engine performance and life. Be certain to remove all
dirt and combustible debris from muffler area.
