4.1.6 Safety instructions for all saws
DANGER:
a)
Keep hands away from cutting area and the blade.
Keep your second hand on auxiliary handle, or motor
housing.
If both hands are holding the saw, they can-
not be cut by the blade.
b)
Do not reach underneath the workpiece.
The guard
cannot protect you from the blade below the work-
piece.
c)
Adjust the cutting depth to the thickness of the work-
piece.
Less than a full tooth of the blade teeth should
be visible below the workpiece.
d)
Never hold piece being cut in your hands or across
your leg. Secure the workpiece to a stable platform.
It is important to support the work properly to mini-
mize body exposure, blade binding, or loss of con-
trol.
e)
Hold power tool by insulated gripping surfaces when
performing an operation where the cutting tool may
contact hidden wiring or its own cord.
Contact with
a "live" wire will also make exposed metal parts of the
power tool "live" and shock the operator.
f)
When ripping always use a rip fence or straight edge
guide.
This improves the accuracy of cut and reduces
the chance of blade binding.
g)
Always use blades with correct size and shape (dia-
mond versus round) of arbour holes.
Blades that do
not match the mounting hardware of the saw will run
eccentrically, causing loss of control.
h)
Never use damaged or incorrect blade washers or
bolt.
The blade washers and bolt were specially
designed for your saw, for optimum performance and
safety of operation.
4.1.7 Further safety instructions for all saws
Causes and operator prevention of kickback:
– kickback is a sudden reaction to a pinched, bound or
misaligned saw blade, causing an uncontrolled saw
to lift up and out of the workpiece toward the opera-
tor;
– when the blade is pinched or bound tightly by the kerf
closing down, the blade stalls and the motor reaction
drives the unit rapidly back toward the operator;
– if the blade becomes twisted or misaligned in the cut,
the teeth at the back edge of the blade can dig into the
top surface of the wood causing the blade to climb
out of the kerf and jump back toward the operator.
Kickback is the result of saw misuse and/or incorrect
operating procedures or conditions and can be avoid-
ed by taking proper precautions as given below.
a)
Maintain a firm grip with both hands on the saw and
position your arms to resist kickback forces. Posi-
tion your body to either side of the blade, but not in
line with the blade.
Kickback could cause the saw to
jump backwards, but kickback forces can be con-
trolled by the operator, if proper precautions are tak-
en.
b)
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. Investi-
gate and take corrective actions to eliminate the
cause of blade binding.
c)
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 bind-
ing, it may walk up or kickback from the workpiece
as the saw is restarted.
d)
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.
e)
Do not use dull or damaged blades.
Unsharpened
or improperly set blades produce narrow kerf caus-
ing excessive friction, blade binding and kickback.
f)
Blade depth and bevel adjusting locking levers must
be tight and secure before making cut.
If blade adjust-
ment shifts while cutting, it may cause binding and
kickback.
g)
Use extra caution when making a "plunge cut" into
existing walls or other blind areas.
The protruding
blade may cut objects that can cause kickback.
4.1.8 Safety instructions for circular saws with
dual actuation of lower blade guard (both
sides of blade)
a)
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 acci-
dentally 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.
b)
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 oper-
ate sluggishly due to damaged parts, gummy deposits,
or a build-up of debris.
c)
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.
d)
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.
