mini cordless portable circular saw PCSS 05-20V
•
Hold the power tool by its insulated gripping surfaces
when performing an operation where the cutting
accessory 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.
•
When ripping, always use a rip fence or straight edge
guide.
This improves the accuracy of cut and reduces the
chance of blade binding.
•
Always use saw 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.
•
Never use damaged or incorrect blade washers or
bolts.
The blade washers and bolt were specially designed
for your saw, for optimum performance and safety of
operation.
Further safety warnings for all saws
Kickback causes and related warnings
A 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.
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
workpiece 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.
•
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.
•
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 backwards while the blade is
in motion or kickback may occur.
Investigate and take
corrective actions to eliminate the cause of blade binding.
•
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.
•
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.
•
Do not use dull or damaged blades.
Unsharpened or
improperly set blades produce narrow kerf causing
excessive friction, blade binding and kickback.
•
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.
•
Use extra caution when sawing into existing walls or
other blind areas.
The protruding blade may cut objects
that can cause kickback.
Safety warnings for circular saws with pendulum guard
and circular saws with tow guard – Lower guard function
•
Check the lower guard for proper closure before each
use. Do not operate the saw if the lower guard does
not move freely and close immediately. Never clamp or
tie the lower guard in the open position.
The lower
guard may be bent if the saw accidentally falls to the floor.
Use the retracting lever to raise the guard and make sure
that it moves freely and does not touch the blade or any
other part of the saw at all cutting angles and depths of
cut.
•
Check that the lower guard spring operates correctly.
If the guard and spring do not operate correctly, have
the saw serviced before use.
Lower guard may operate
sluggishly due to damaged parts, gummy deposits, or a
build-up of debris.
•
Lower guard may be retracted manually only for
special cuts such as "plunge cuts" and "compound
cuts". Raise lower guard by retracting lever and as
soon as blade enters the material, the lower guard
must be released.
For all other sawing, the lower guard
should operate automatically.
•
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.
Additional safety warnings for portable circular saws
•
Do not reach into the chip ejector with your hands.
They could be injured by rotating parts.
•
Do not work overhead with the saw.
In this manner you
do not have sufficient control over the power tool.
•
Do not use abrasive wheels.
