OPERATION Inspect the workpiece for knots or nails before cutting. Never saw into a knot or nail. Make straight cuts. Always use a straight edge guide when rip cutting. This helps prevent twisting the blade. Use clean, sharp, and properly set blades. Never make cuts with dull blades. Support the workpiece properly before beginning a cut. Use steady, even pressure when making a cut. Never force a cut. 51 .5 45 30 15 Do not cut warped or wet lumber.
OPERATION If at any time the lower blade guard does not snap closed, unplug the saw from the power supply. Exercise the lower guard by moving it rapidly back and forth from the full open position to the closed position several times. Normally this will restore the guard to its normal operating condition. If it does not correct a slow or sluggish closing lower guard, do not use the saw. Take it to an authorized factory service center for repair. SWITCH STARTING/STOPPING THE SAW See Figure 10.
OPERATION USING THE LASER GUIDES See Figure 12. push in TURN ON laser guide BUTTON WARNING: Do not stare into the laser beams or turn the lasers on when the tool is not in use.

MAINTENANCE Electric tools used on fiberglass material, wallboard, spackling compounds, or plaster are subject to accelerated wear and possible premature failure because the fiberglass chips and grindings are highly abrasive to bearings, brushes, commutators, etc. Consequently, we do not recommend using this product for extended work on these types of materials. However, if you do work with any of these materials, it is extremely important to clean the product using compressed air.
