Operation
CUTTING WITH THE POWER CUTTER
DO NOT insert the guidebar into a slot narrower than the width of the chain.
Rapid pushback, kickback and/or chain breakage could result.
Slippery or unstable surfaces such as ladders may cause a loss of balance
or control of the power cutter.
Always keep proper footing and operate the power cutter only when standing
on fixed, secure and level surface.
Unexpected loss of control of the power cutter and loss of balance can
result in injury.
Do not overreach and do not cut above shoulder height.
IMPORTANT
WARNING
CAUTION
Do not allow workpiece to pinch the guidebar and chain, or rapid pushback
could result.
Always cut bottom of opening first and assure workpiece is secure and does
not shift during cutting operations.
Do not operate power cutter upside down.
Cutting debris can be directed back towards the operator.
Always operate power cutter at full throttle.
For best results, always operate the power cutter at full power.
Take special precautions when cutting in horizontal orientation.
Be aware that debris may be ejected differently than when cutting in a vertical
position.
Be sure cut concrete cannot fall and injure the operator or bystanders.
Assure cut piece is controlled and does not fall unexpectedly.
NOTE: Concrete is very heavy; one cubic foot = 30 cm x 30 cm x 30 cm = 68 kg
(12 in x 12 in x 12 in = 150 lbs).
