Whenever the unit will not be used for
30 days or longer, use the following
procedures to prepare it for storage:
n Clean external parts thoroughly.
n Drain all the fuel from the fuel tank.
IMPORTANT!
All stored fuels should be stabilized
with a fuel stabilizer such as STA-BIL™,
if oil with fuel stabilizer is not used.

Blade Sharpening

With the file or a grinder, file a blade as
follows.
WARNING!
Sharpen only the cutting teeth of a
blade. DO NOT alter the contour of the
blade in any way. In order to keep the
blade in balance, all cutting edges must
be sharpened equally. DO NOT file the
tips of the teeth too sharp.
Make sure the width of the 4 sides
are all the same.

7 ml of 2-cycle mixing oil into the
cylinder through the spark plug hole.

any worn or damaged parts.
n Remove the air cleaner element from the
carburetor and clean it thoroughly with
soap and water. Let dry and reassemble
