Further Safety Instructions For All Saws - KRESS KU436P Manual

5) Service
a) Have your power tool serviced by a
qualified repair person using only identical
replacement parts. This will ensure that the safety of the
power tool is maintained.
SAFETY WARNINGS FOR
ALL SAWS
Cutting procedures
a) DANGER: Keep hands away from cutting
area and the blade. If both hands are holding the
saw, they cannot be cut by the blade.
b) Do not reach underneath the workpiece. The
guard cannot protect you from the blade below the workpiece.
c) Adjust the cutting depth to the thickness of
the workpiece. 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 minimize body exposure, blade binding, or loss of control.
e) Hold the power tool by insulated gripping
surfaces only, 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 could
give the operator an electric shock.
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 (diamond versus round) of arbor
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.

INSTRUCTIONS FOR ALL
SAWS
Kickback causes and related warnings
— kickback is a sudden reaction to a pinched, jammed or
misaligned saw blade, causing an uncontrolled saw to
lift up and out of the workpiece toward the operator;
— when the blade is pinched or jammed 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 avoided by
taking proper precautions as given below.
a) Maintain a firm grip on the saw and position
your arms to resist kickback forces. Position
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 controlled by the
operator, if proper precautions are taken.
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. Investigate and take
corrective actions to eliminate the cause of blade binding.
c) When restarting a saw in the workpiece,
center 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.
d) Support large panels to minimize 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 causing excessive
friction, blade binding and kickback.
f) 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.
g) Use extra caution when sawing into existing
walls or other blind areas. The protruding blade may
cut objects that can cause kickback.
SAFETY INSTRUCTIONS
FOR CIRCULAR SAW WITH
INNER PENDULUM GUARD
Lower Guard Function
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 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.
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 operate sluggishly due to
damaged parts, gummy deposits, or a build-up of debris.
c) The 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.
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.
