starting or operating the unit.

Be aware of kickback!

Kickback may force the cut-off

wheel up and back toward the

operator lightning-fast. Kick-

back can occur whenever the

upper half of the cut-off wheel

touches an object. Never cut

an object using the upper-

half of the cut-off wheel.

When operating, always wear

snug-fitting clothing, safety

gloves, safety non-skid

footwear, hearing protection, a

dust-proof mask, a helmet and

goggles.

WARNING!

When using the cut-off saw, the wheel guard must be securely in position as a protection against a broken wheel. If the wheel guard is not in place, a broken wheel could project fragments at high speed and strike you or others, possibly resulting in serious injury.

Cutting

 

 

This unit performs most efficiently when cutting between 8,500 and 9,500 min-1(rpm). While running the engine at full throttle, apply slight pressure to the cut-off wheel against an object so that engine speed stays at 8,500–9,500 min-1(rpm). Too much pressure to the wheel will lower wheel speed, reduc- ing cutting efficiency considerably.

1.

Make sure you have a clear work

 

area and secure footing.

2.

Position the cut-off wheel vertically

 

to an object. Start cutting at a low

 

speed and then gradually acceler-

 

ate the speed.
