Clear a safe work area
before cutting.
Wear hearing protection and eye protection
such as a face shield or goggles when

Always wear gloves when
operating this saw.
Use full-throttle while
cutting and apply only
enough bar pressure to
maintain engine speeds of
9,000-10,000 min

Wear close-tting clothing to
protect your legs and arms.
Do not wear clothing or
jewelry that could get caught
in the machinery or brush.
Keep a proper footing (do
not overreach)!
Wear appropriate
non-skid footwear.
IMPORTANT!
Always use full throttle while cutting!
Keep the chain sharp and let the saw do
the work! Forcing the saw into the wood
reduces cutting performance, and can
damage the saw through overheating!
Always wear leg protection (Chaps)
made of a cut-resistant material such
as ballistic nylon covering the full length
of the thigh to the top of the boot.
Stop the saw before
moving it to or from the
work area.
