9.
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.
Lower guard function
1.
Check the lower guard for proper closing
before each use. Do not operate the saw if the
lower guard does not move freely and close
instantly. Never clamp or tie the lower guard
into the open position. If the saw is accidentally
dropped, the 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.
2.
Check the operation of the lower guard spring. If
the guard and the spring are not operating prop-
erly, they must be serviced before use. Lower
guard may operate sluggishly due to damaged parts,
gummy deposits, or a build-up of debris.
3.
The lower guard may be retracted manually
only for special cuts such as "plunge cuts"
and "compound cuts". Raise the lower guard
by the retracting handle and as soon as the
blade enters the material, the lower guard
must be released. For all other sawing, the lower
guard should operate automatically.
4.
Always observe that the lower guard is cover-
ing the blade before placing the 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.
5.
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.
Riving knife function
1.
Use the appropriate saw blade for the riving
knife. For the riving knife to function, the body of
the blade must be thinner than the riving knife and
the cutting width of the blade must be wider than
the thickness of the riving knife.
2.
Adjust the riving knife as described in this
instruction manual. Incorrect spacing, position-
ing and alignment can make the riving knife inef-
fective in preventing kickback.
3.
Always use the riving knife except when plunge
cutting. The riving knife must be replaced after
plunge cutting. The riving knife causes interference
during plunge cutting and can create kickback.
4.
For the riving knife to work, it must be engaged
in the workpiece. The riving knife is ineffective in
preventing kickback during short cuts.
5.
Do not operate the saw if the riving knife is
bent. Even a light interference can slow the clos-
ing rate of a guard.
Additional safety warnings
1.
Use extra caution when cutting damp wood,
pressure treated lumber, or wood containing
knots. Maintain smooth advancement of tool with-
out decrease in blade speed to avoid overheating
the blade tips.
2.
Do not attempt to remove cut material when
blade is moving. Wait until blade stops before
grasping cut material. Blades coast after turn off.
3.
Avoid cutting nails. Inspect for and remove all
nails from lumber before cutting.
Place the wider portion of the saw base on
4.
that part of the workpiece which is solidly
supported, not on the section that will fall off
when the cut is made. If the workpiece is short
or small, clamp it down. DO NOT TRY TO HOLD
SHORT PIECES BY HAND!
5.
Before setting the tool down after completing a
cut, be sure that the guard has closed and the
blade has come to a complete stop.
6.
Never attempt to saw with the circular saw
held upside down in a vise. This is extremely
dangerous and can lead to serious accidents.
7.
Some material contains chemicals which may be
toxic. Take caution to prevent dust inhalation and
skin contact. Follow material supplier safety data.
8.
Do not stop the blades by lateral pressure on
the saw blade.
9.
Do not use any abrasive wheels.
10. Only use the saw blade with the diameter that
is marked on the tool or specified in the man-
ual. Use of an incorrectly sized blade may affect
the proper guarding of the blade or guard opera-
tion which could result in serious personal injury.
11.
Keep blade sharp and clean. Gum and wood pitch
hardened on blades slows saw and increases poten-
tial for kickback. Keep blade clean by first removing
it from tool, then cleaning it with gum and pitch
remover, hot water or kerosene. Never use gasoline.
12. Wear a dust mask and hearing protection when
use the tool.
