Cutting with the Saw

Clear a safe work area

before cutting.

Wear hearing protection and eye protection

such as a face shield or goggles when

operating the unit to shield against saw dust.

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

-1

.

Wear close-fitting 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.

THINK

SAFETY!

WARNING!
NEVER operate with a

loose saw chain! NEVER operate
the saw if any component parts are
damaged, loose, or missing!
