KICKBACK-CAUSES

•  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 reac-
tion 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 towards operator

KICKBACK - OPERATOR PREVENTION

Kickback is the result of tool misuse and/or incorrect
operating procedures or conditions and can be avoided
by taking proper precautions as given below

• Maintain a

rm 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

(investi-

gate and take corrective actions to eliminate the cause
of blade binding; avoid cutting nails or screws)

• 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 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)

• Do not use a dull or damaged blade

(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 making a plunge cut into
existing walls or other blind areas

(the protruding

blade may cut objects that can cause kickback)

WARNING

•  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

• Check the operation of the lower guard spring;
if the guard and the spring are not operating prop-
erly, they must be serviced before use

(lower guard

may operate sluggishly due to damaged parts, gummy
deposits, or a build-up of debris)

• 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)

• Always observe that the lower guard is cover-
ing the blade before placing saw down on bench
or

oor

(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)
•  Avoid damage that can be caused by screws, nails
and other elements in your workpiece; remove them be-
fore you start cutting
•  When you put away the tool, switch off the motor and
ensure that all moving parts have come to a complete
standstill
•  Use completely unrolled and safe extension cords
with a capacity of 16Amps (U.K. 13Amps)
•  In case of jamming or electrical or mechanical mal-
function, immediately switch off the tool and disconnect
the plug
• The SBM Group can assure

awless functioning of

the tool only when original accessories are used
•  Use only accessories with an allowable speed
matching at least the highest no-load speed of the tool
•  Never use the tool without the original protection
guard system
•  This tool should not be used by people under the age
of 16 years
•  The noise level when working can exceed 85 dB(A);
wear ear protection
•  If the cord is damaged or cut through while working,
do not touch the cord, but immediately disconnect the
plug
•  Never use tool when cord is damaged; have it re-
placed by a quali

ed person

•  Always check that the supply voltage is the same as
the voltage indicated on the nameplate of the tool (tools
with a rating of 230V or 240V can also be connected to
a 220V supply)
•  This tool is not suitable for wet cutting
•  After switching off your circular saw, never stop the
rotation of the saw blade by a lateral force applied
against it
•  Never use circular saw blades made of high speed
steel (HSS)
•  Never use grinding/cutting discs with this tool

• Do not work materials containing asbestos

(as-

bestos is considered carcinogenic)

• Take protective measures when during work
dust can develop that is harmful to one’s health,
combustible or explosive

(some dusts are considered

carcinogenic); wear a dust mask and work with dust/
chip extraction when connectable
•  Do not attempt to cut extremely small workpieces
•  Remove all obstacles on top of as well as under-
neath the cutting path before you start cutting
•  Do not work overhead with the tool
•  Only use a saw table provided with a switch that pre-
vents restarting of the motor after interruption of volt-
age
•  Only use a saw table provided with a kerf guide
