• Stand at a comfortable distance from the work piece.
• Make sure that the cutting blade can move freely
and are not in contact with anything when the engine
is started.
• Always monitor the product when the engine
operates.
• If the blade is binding in the cut or when aborting
a cut, release the throttle and wait until the blade
stops. Do not extract the blade from the cut while the
blade is in motion otherwise kickback may occur.
• Apply the cutting blade gently with high rotating
speed (full throttle). Maintain full speed until cutting
is complete.
• Let the machine work without forcing or pressing the
blade. If the blade starts to wobble, reduce the feed.
If the blade still wobble, stop cutting and replace the
blade.
• Feed down the machine in line with the blade. Do
not twist in the cut as side pressure can cause
binding in the cutting slot and cause blade damage
or kickback.

• During all cutting operations, make sure that the
blade guard extender and the dust shield are flush
with the work piece.
Push the cutting blade to the full cutting depth at
the top/ front of the cut and move the cutting blade
slowly down/rear. This decreases the temperature of
the cutting blade and helps to collect the dust.
