Blade guard cleaning
When changing the circular saw blade, make sure to
also clean the upper and lower blade guards of accu-
mulated sawdust as discussed in the Maintenance
section. Such efforts do not replace the need to check
lower guard operation before each use.

Hold the tool firmly. The tool is provided with both a front
grip and rear handle. Use both to best grasp the tool. If
both hands are holding saw, they cannot be cut by the
blade. Set the base on the workpiece to be cut without
the blade making any contact. Then turn the tool on and
wait until the blade attains full speed. Now simply move
the tool forward over the workpiece surface, keeping
it flat and advancing smoothly until the sawing is com-
pleted. To get clean cuts, keep your sawing line straight
and your speed of advance uniform. If the cut fails to
properly follow your intended cut line, do not attempt
to turn or force the tool back to the cut line. Doing so
may bind the blade and lead to dangerous kickback and
possible serious injury. Release switch, wait for blade
to stop and then withdraw tool. Realign tool on a new
cut line, and start cut again. Attempt to avoid positioning
which exposes operator to chips and wood dust being
ejected from saw. Use eye protection to help avoid
injury.
