10. When blade is binding, or when interrupting a
cut for any reason, release the trigger and
hold the saw motionless in the material until
the blade comes to a complete stop. Never
attempt to remove the saw from the work or
pull the saw backward while the blade is in
motion or kickback may occur. Investigate and
take corrective actions to eliminate the cause of
blade binding.
11.
When restarting a saw in the workpiece,
centre the saw blade in the kerf and check
that saw teeth are not engaged into the
material. If saw blade is binding, it may walk up
or kickback from the workpiece as the saw is
restarted.
12. Support large panels to minimise the risk of
blade pinching and kickback. Large panels
tend to sag under their own weight. Supports
must be placed under the panel on both sides,
near the line of cut and near the edge of the
panel.
13. Do
not
use
Unsharpened or improperly set blades produce
narrow kerf causing excessive friction, blade
binding and kickback.
14. 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.
15. Use extra caution when sawing into existing
walls or other blind areas. The protruding blade
may cut objects that can cause kickback.
Lower guard function
16. 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.
17. 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.
18. 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.

or
damaged
19. 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.
20. To check lower guard, open lower guard by
hand, then release and watch guard closure.
Also check to see that retracting handle does
not touch tool housing. Leaving blade exposed
is VERY DANGEROUS and can lead to serious
personal injury.
Additional safety warnings
21. Do not stop the blades by lateral pressure on
the blade.
22. DANGER:
Do not attempt to remove cut material when
blade is moving.
CAUTION: Blades coast after turn off.
23. Place the wider portion of the tool base on
blades.
that part of the workpiece which is solidly
supported, not on the section that will fall off
when the cut is made.
24. Never attempt to make a cut with the tool held
upside down in a vise. This is extremely
dangerous and can lead to serious accidents.
25. Wear safety goggles and hearing protection
during operation.
26. Always use blades recommended in this
manual. Do not use any abrasive wheels.
