CS235-20B ELECTRIC CIRCULAR SAW
d) Never hold the workpiece in your hands or
across your leg while cutting. Secure the
workpiece to a stable platform.
It is important to support the work properly to
minimise body exposure, blade binding, or loss
of control.
e) Hold the 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
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 arbour
holes.
Blades that do not match the mounting hardware
of the saw will run off-centre, 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.
2) Further safety 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 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
[7741438] CS235-20B MULTI MANUAL(EN62841)_200831.indd 3 [7741438] CS235-20B MULTI MANUAL(EN62841)_200831.indd 3
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,
centre the saw blade in the kerf so that the
saw teeth are not engaged into the material.
If a saw blade binds, 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 the 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.
3) Safety instructions for saws with guard -
[Lower guard function]
a) Check the lower guard for proper closing
before each use. Do not operate the saw if
the lower guard does not move freely and
close instantly. Never clamp or tie the lower
guard into the open position.
If the saw is accidentally dropped, the 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.
