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.
Do not cut warped or wet lumber.
Hold the saw firmly with both hands and keep your body in a balanced position so as to resist the forces if kickback should occur.

When using the saw, always stay alert and exercise con- trol. Do not remove the saw from the workpiece while the blade is moving.

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 the 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 the saw down. Remove saw blade from the saw and use gum and pitch remover, hot water, or kerosene to remove these ac- cumulations. DO NOT USE GASOLINE.
BLADE GUARD SYSTEM
See Figure 11.
The lower blade guard attached to the circular saw is there for your protection and safety. Do not alter it for any reason. If it becomes damaged, do not operate the saw until you have the guard repaired or replaced. Always leave guard in operating position when using the saw.
DANGER:
When sawing through work, lower blade guard does not cover blade on the underside of work. Since blade is exposed on underside of work, keep hands and fingers away from cutting area. Any part of your body coming in contact with moving blade will result in serious injury.

CAUTION:
Never use saw when guard is not operating correctly. Check the guard for correct operation before each use. The guard is operating correctly when it moves freely and readily returns to the closed position. If you drop the saw, check the lower blade guard and bumper for damage at all depth settings before reuse.
WARNING:
Never tie the lower blade guard in a raised position. Leav- ing the blade exposed could lead to serious injury.
