Before starting a circular saw, be sure the power cord and extension cord are out of the blade path and are sufficiently long to freely complete the cut.For example, tying back or removing the guard. Never defeat the guard to expose the blade.If a guard seems slow to return or "hangs up" repair or adjust it immediately. Check often to assure that guards return to their normal position quickly.
Is the blade guard working? Check for proper operation before each cut.Be sure the blade washers (flanges) are correctly assembled on the shaft and that the blade is properly supported. Check blades carefully before each use for proper alignment and possible defects.Check this carefully: Does it have the proper size and shape arbor hole? Is the speed marked on the blade at least as high as the no load RPM on the saw's nameplate? Use the correct blade for the application.They also waste power and reduce motor and switch life. Dull blades cause binding, stalling and possible kickback. Do not use a tool if the switch does not turn it off when returned to the "off" position after release. Do not use a circular saw that is too heavy for you to easily control.Do not wear loose clothing, jewelry or any dangling objects that may catch in rotating parts or accessories.Wear hearing protection during extended periods of operation. Use a dust mask in dusty work conditions.Always wear safety goggles or safety glasses with side shields complying with current national standard, and a full face shield when needed.Failure to follow these safety rules may result in serious injury.
Not doing so must be considered dangerous. The following are specific safety "musts" when using any portable circular saw. Familiarity should not breed carelessness.
