Makita N5900B Instruction Manual page 6

Lower guard may operate sluggishly due to
damaged parts, gummy deposits, or a build-up of
debris.
12. Lower guard should be retracted manually
only for special cuts such as "plunge cuts"
and "compound cuts." Raise lower guard by
retracting handle and as soon as blade enters
the material, the lower guard must be released.
For all other sawing, the lower guard should
operate automatically.
13. Always observe that the lower guard is
covering the blade before placing saw down
on bench or floor. An unprotected, coasting
blade will cause the saw to walk backwards,
cutting whatever is in its path. Be aware of the
time it takes for the blade to stop after switch is
released. Before setting the tool down after
completing a cut, be sure that the lower guard has
closed and the blade has come to a complete
stop.
14. Use extra caution when cutting damp wood,
pressure treated lumber, or wood containing
knots. Adjust speed of cut to maintain smooth
advancement of tool without decrease in blade
speed.
15. Avoid Cutting Nails. Inspect for and remove all
nails from lumber before cutting.
16. Place the wider portion of the saw base on that
part of the workpiece which is solidly
supported, not on the section that will fall off
when the cut is made. As examples, Fig. 1
illustrates the RIGHT way to cut off the end of
a board, and Fig. 2 the WRONG way. If the
workpiece is short or small, clamp it down. DO
NOT TRY TO HOLD SHORT PIECES BY HAND!

17. Never attempt to saw with the circular saw
held upside down in a vise. This is extremely
dangerous and can lead to serious accidents.
