MAINTENANCE AND
LUBRICATION
Your Leaf Blower, like all machines with moving
parts, must receive care and maintenance. The
following tips, if used, will contribute many trouble-
free hours to your blower.
1. Check oil level frequently. When changing oil,
make sure dirt and debris is cleaned off oil sump
before removing oil plug.
2. Keep blower clean, expecially the engine, and
engine air filter.
3. Check all nuts, bolts and screws occasionally to be
sure blower is in good operating condition.
4. The wheel bearings are pre-lubricated at the
factory and should require no further attention
until blower is serviced. However, it is advisable
to remove the wheels and apply a small amount
of light oil to each axle, at least once a season.
OFF-SEASON STORAGE
If you are going to store your blower for any length of
time (30 days or longer), it is important that the
following steps be taken:
1. Drain the gas tank. Start the engine. Allow it to
run out of gas. Gasoline left in the engine will
leave gum deposits in the carburetor and gas tank.
2. Clean engine of all foreign matter.
3. Lubricate cylinder by removing the spark plug
and pour in one ounce of clean lubricating oil
through the spark plug hole into the cylinder.
Crank engine slowly to spread oil and replace
spark plug. To start after storage, remove spark
plug and rotate engine with starter to remove
excess oil.
