Operation
WARNING!
Never permit bystanders or animals near the unit when 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 foot- wear, 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.
Wet or Dry Operation
This unit is designed to be operated for either dry or wet cutting. A water dust-suppression kit is available for this unit but is not supplied in the unit packaging. Please refer to the assembly and operating instructions supplied with the water dust-suppres- sion kit.
Adjusting Wheel Guard Angle
Adjust the position of the wheel guard so that fragments will not fly toward you if the wheel fractures. To reposi- tion the wheel guard, loosen the lock knob (counterclockwise). When the wheel guard is positioned correctly, securely tighten the lock knob.
See Figure 14.

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, reducing 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 accelerate the speed.
