ENGLISH (Original instructions)
Slippery handles and greasy surfaces do not allow for safe
handling and control of the tool in unexpected situations.
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.
Additional power tool safety warnings
Warning! Additional safety warnings for saws
and cutting procedures.
a. DANGER! 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 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 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
(diamond 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.
Further safety instructions for all saws
Causes and operator prevention of kickback:
u
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 operator;
u
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;
u
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 with both hands 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 the 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, 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.
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 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 making a "plunge cut" into
existing walls or other blind areas. The protruding blade
may cut objects that can cause kickback.
Safety instructions for circular saws with outer or
inner pendulum guards
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.
