To avoid kickback, do support
board or panel near the cut.

Do not support board or
panel away from the cut.

Do not use dull or damaged blades.
Unsharpened
produce narrow kerf causing excessive friction,
blade binding and kickback.
Blade depth and bevel adjusting locking
levers must be tight and secure before
making cut. If blade adjustment shifts while
cutting, it may cause binding and kickback.
Use extra caution when sawing into
existing walls or other blind areas. The
protruding blade may cut objects that can
cause kickback.
10. Check lower guard for proper closing before
each use. Do not operate the saw if lower
guard does not move freely and close instantly.
Never clamp or tie the lower guard into the
open position. If saw is accidentally dropped,
lower guard may be bent. Raise the lower guard
with the retracting handle and make sure it moves
freely and does not touch the blade or any other
part, in all angles and depths of cut.
11.
Check the operation of the lower guard spring.
If the guard and the spring are not operating
properly, they must be serviced before use.
Lower guard may operate sluggishly due to
damaged parts, gummy deposits, or a build-up of
debris.

12. Lower guard may 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.
14. ALWAYS hold the tool firmly with both hands.
NEVER place your hand or fingers behind the
saw. If kickback occurs, the saw could easily jump
backwards over your hand, leading to serious
personal injury.

15. Never force the saw. Push the saw forward at a
speed so that the blade cuts without slowing.
Forcing the saw can cause uneven cuts, loss of
accuracy, and possible kickback.
16. Use extra caution when cutting damp wood,
pressure treated lumber, or wood containing
knots. Maintain smooth advancement of tool
without decrease in blade speed to avoid
overheating the blade tips.
17. Do not attempt to remove cut material when
blade is moving. Wait until blade stops before
grasping cut material. CAUTION: Blades coast
after turn off.
18. Avoid Cutting Nails. Inspect for and remove all
nails from lumber before cutting.
19. Place the wider portion of the saw base on that
part
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!
