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, especially 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.
5. 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:
A. 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.
B. Clean engine of all foreign matter.
C. 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.
