Safety instructions for table saws

Guarding related warnings
Keep guards in place. Guards must be in work-
1.
ing order and be properly mounted. A guard
that is loose, damaged, or is not functioning cor-
rectly must be repaired or replaced.
2. Make sure the saw blade is not contacting the
guard, riving knife or the workpiece before the
switch is turned on. Inadvertent contact of these items
with the saw blade could cause a hazardous condition.
3. Adjust the riving knife as described in this
instruction manual. Incorrect spacing, position-
ing and alignment can make the riving knife inef-
fective in reducing the likelihood of kickback.
4. For the riving knife and anti-kickback pawls to
work, they must be engaged in the workpiece.
The riving knife and anti-kickback pawls are ineffec-
tive when cutting workpieces that are too short to
be engaged with the riving knife and anti-kickback
pawls. Under these conditions a kickback cannot be
prevented by the riving knife and antikickback pawls.
Use the appropriate saw blade for the riving
5.
knife. For the riving knife to function properly, the
saw blade diameter must match the appropriate
riving knife and the body of the saw blade must be
thinner than the thickness of the riving knife and
the cutting width of the saw blade must be wider
than the thickness of the riving knife.
Cutting procedures warnings
1. DANGER: Never place your fingers or
hands in the vicinity or in line with the saw
blade. A moment of inattention or a slip could
direct your hand towards the saw blade and result
in serious personal injury.
Feed the workpiece into the saw blade only
2.
against the direction of rotation. Feeding the
workpiece in the same direction that the saw blade is
rotating above the table may result in the workpiece,
and your hand, being pulled into the saw blade.
3. Never use the mitre gauge to feed the workpiece
when ripping and do not use the rip fence as a
length stop when cross cutting with the mitre
gauge. Guiding the workpiece with the rip fence
and the mitre gauge at the same time increases the
likelihood of saw blade binding and kickback.
4. When ripping, always apply the workpiece feed-
ing force between the fence and the saw blade.
Use a push stick when the distance between the
fence and the saw blade is less than 150 mm,
and use a push block when this distance is less
than 50 mm. "Work helping" devices will keep your
hand at a safe distance from the saw blade.
5. Use only the push stick provided by the manu-
facturer or constructed in accordance with the
instructions. This push stick provides sufficient
distance of the hand from the saw blade.
Never use a damaged or cut push stick. A
6.
damaged push stick may break causing your hand
to slip into the saw blade.
7. Do not perform any operation "freehand". Always
use either the rip fence or the mitre gauge to posi-
tion and guide the workpiece. "Freehand" means
using your hands to support or guide the workpiece,
in lieu of a rip fence or mitre gauge. Freehand sawing
leads to misalignment, binding and kickback.
8. Never reach around or over a rotating saw
blade. Reaching for a workpiece may lead to
accidental contact with the moving saw blade.
9. Provide auxiliary workpiece support to the rear
and/or sides of the saw table for long and/or
wide workpieces to keep them level. A long and/
or wide workpiece has a tendency to pivot on the
table's edge, causing loss of control, saw blade
binding and kickback.
10. Feed workpiece at an even pace. Do not bend
or twist the workpiece. If jamming occurs, turn
the tool off immediately, unplug the tool then
clear the jam. Jamming the saw blade by the
workpiece can cause kickback or stall the motor.
Do not remove pieces of cut-off material while
11.
the saw is running. The material may become
trapped between the fence or inside the saw blade
guard and the saw blade pulling your fingers into
the saw blade. Turn the saw off and wait until the
saw blade stops before removing material.
12. Use an auxiliary fence in contact with the table
top when ripping workpieces less than 2 mm
thick. A thin workpiece may wedge under the rip
fence and create a kickback.
Kickback causes and related warnings
Kickback is a sudden reaction of the workpiece due to a
pinched, jammed saw blade or misaligned line of cut in
the workpiece with respect to the saw blade or when a
part of the workpiece binds between the saw blade and
the rip fence or other fixed object.
Most frequently during kickback, the workpiece is lifted
from the table by the rear portion of the saw blade and
is propelled towards the operator.
Kickback is the result of saw misuse and/or incorrect
operating procedures or conditions and can be avoided
by taking proper precautions as given below.
1. Never stand directly in line with the saw blade.
Always position your body on the same side of
the saw blade as the fence. Kickback may propel
the workpiece at high velocity towards anyone
standing in front and in line with the saw blade.
2. Never reach over or in back of the saw blade
to pull or to support the workpiece. Accidental
contact with the saw blade may occur or kickback
may drag your fingers into the saw blade.
