LINE GUIDE

FIG. 7

For a straight 90° cut, use right side of notch in the foot. For 45°-56° bevel cuts, use the left side (Fig. 7). The cutting guide notch will give an approximate line of cut. Make sample cuts in scrap lumber to verify actual line of cut. This will be helpful because of the number of different blade types and thicknesses available. To ensure minimum splintering on the good side of the material to be cut, face the good side down.

SWITCH

When starting the tool, ! WARNING hold it with both hands. The

torque from the motor can cause the tool to twist.

To turn tool “ON”, squeeze the trigger switch. To turn the tool “OFF”, release the trigger switch, which is spring loaded and will return to the off position automatically.

Your saw should be running at full speed BEFORE starting the cut, and turned off only AFTER completing the cut. To increase switch life, do not turn switch on and off while cutting.

GENERAL CUTS

Always hold the saw handle with one hand and the auxiliary handle or housing with the other.

Always be sure either hand does not interfere with the

free movement of the lower guard.

Maintain a firm grip and operate the switch with a decisive action. Never force the saw. Use light and continuous pressure.

After completing a cut and the trigger has been released, be aware of the necessary time it

takes for the blade to come to a complete stop during coast down. Do not allow the saw to brush against your leg or side, since the lower guard is retractable, it could catch on your clothing and expose the blade. Be aware of the necessary blade exposures that exist in both the upper and lower guard areas.

When cutting is interrupted, to resume cutting: squeeze the trigger and allow the blade to reach full speed, re-enter the cut slowly and resume cutting.

When cutting across the grain, the fibers of the wood have a tendency to tear and lift. Advancing the saw slowly minimizes this effect. For a finished cut, a cross cut blade or miter blade is recommended.

CUTTING MASONRY/METAL

This tool is not recommended for continuous and general usage with metal or masonry cut- off wheels. If you use your saw for cutting these materials, use the appropriate wheel for the material being cut.

When cutting masonry, do not cut a depth of more than 1/4 inch (6 mm). Make successive passes to achieve desired depth. Apply a light forward pressure. Do not overload motor. Disconnect plug from power source and clean dust from air vents frequently. Metal cutting is done at full depth.

Clean guards frequently to ! WARNING assure a rapid return of lower guard. The lower guard may become

sluggish when cutting masonry materials.

! WARNING Abrasive Cut Off Wheels must have a maximum safe operating speed greater than the “no

load RPM” marked on the tool’s nameplate. Wheels running over the rated

speed can fly apart and cause injury.

Do not use the abrasive ! WARNING cut off wheel near flammable materials. Sparks from the

wheel could ignite these materials.

This machine is not ! WARNING intended to be used with Wet Diamond Wheels. Using water or other

liquid coolants with this machine may result in electrocution or shock. Use of Dry Diamond Wheels is acceptable.
