SAW BLADES
The best of saw blades will not cut efficiently if they are not kept clean, sharp, and properly set. Using a dull blade will place a heavy load on your saw and increase the danger of kickback. Keep extra blades on hand, so that sharp blades are always available.
Gum and wood pitch hardened on blades will slow your saw down. Use gum and pitch remover, hot water, or kerosene to remove these accumulations. Do not use gasoline.
BLADE GUARD SYSTEM
The lower blade guard attached to your circular saw is there for your protection and safety. It should never be altered for any reason, if it becomes damaged or begins to return slow or sluggish, do not operate your saw until the damage has been repaired or replaced. Always leave guard in operating position when using saw.
,_L DANGER: When r,.awingthrough workpiece, lower blade guard does not cover blade on the
underside of workpiece. Since blade is exposed on underside of workpiece, keep hands and fingers away from cutting area. Any part of your body coming in contact with moving blade will result in serious injury. See Figure 5.

KICKBACK==
BLADESETTOO DEEP | Fig. 6 |
The best guard against kickback is to avoid dangerous practices.
Kickback occurs when the blade stalls rapidly and the saw is driven back towards you. Blade stalling is caused by any action which pinches the blade in the wood.
_i DANGER: Release switch immediately if blade binds or saw stalls. Kickback could cause you to
lose control of your saw. Loss of control can lead to serious injury.
KICKBACK IS CAUSED BY:
•Incorrect blade depth setting. See Figure 6.
•Sawing into knots or nails in workpiece.
•Twisting blade while making a cut.
•Making a cut with a dull, gummed up, or improperly set blade.
•Incorrectly supporting workpiece. See Figure 7.
_L CAUTION: Never use saw when guard is not operating correctly. Guard should be checked for
correct operation before each use. If you drop your saw, check the lower blade guard and bumper for damage at all depth settings before reuse. Note: The guard is operating correctly when it moves freely and readily returns to the closed position. If for any reason your lower blade guard does not close freely, take it to the nearest Sears Parts and Repair Center for service before using.
