in balance, all cutting edges must be
sharpened equally. DO NOT file the
tips of the teeth too sharp.
The sharpening angle should be 45° approx.
Do not file the tips of the blade too sharp. Leave 0.2~0.5mm

WARNING!
Before performing any

or cleaning work on the
machine, make sure the engine and
cutting attachment are completely
stopped. Disconnect the spark plug
wire before performing service or
maintenance work.
WARNING!
Never repair a damaged

shape. An altered blade may break
during operation, resulting in serious
personal injury.

Daily Maintenance

Prior to each work day, perform the
following:
 Remove the dirt and debris from the
engine, check the cooling fins and air
cleaner for clogging, and clean them as
necessary.
 Carefully remove any accumulations
of dirt or debris from the muffler and
fuel tank. Dirt buildup in these areas
can lead to engine overheating, fire, or
premature wear.
 Check for loose or missing screws or
components. Make sure the cutting at-
tachment is securely fastened.
 Check the machine for leaking fuel or
grease.
