ADDITIONAL SPECIFIC SAFETY RULES  
Safety Instructions for All Operations  
a) This power tool is intended to function as  
a cut-off tool. Read all safety warnings,  
instructions, illustrations and specifications  
provided with this power tool. Failure to follow  
all instructions listed below may result in electric  
shock, fire and/or serious injury.  
g) If devices are provided for the connection  
of dust extraction and collection facilities,  
ensure these are connected and properly  
used. Use of dust collection can reduce  
dust-related hazards.  
4) POWER TOOL USE AND CARE  
b) Operations such as grinding, sanding, wire  
brushing, polishing are not recommended  
to be performed with this power tool.  
Operations for which the power tool was not  
designed may create a hazard and cause  
personal injury.  
a) Do not force the power tool. Use the  
correct power tool for your application.  
The correct power tool will do the job  
better and safer at the rate for which it  
was designed.  
b) Do not use the power tool if the switch  
does not turn it on and off. Any power  
tool that cannot be controlled with the switch  
is dangerous and must be repaired.  
c) Disconnect the plug from the power  
source and/or the battery pack from  
the power tool before making any  
adjustments, changing accessories, or  
storing power tools. Such preventive safety  
measures reduce the risk of starting the  
power tool accidentally.  
c) Do not use accessories which are not  
specifically designed and recommended  
by the tool manufacturer. Just because the  
accessory can be attached to your power tool,  
it does not assure safe operation.  
d) The rated speed of the accessory must be at  
least equal to the maximum speed marked  
on the power tool. Accessories running faster  
than their rated speed can break and fly apart.  
e) The outside diameter and the thickness of  
your accessory must be within the capacity  
rating of your power tool. Incorrectly sized  
accessories cannot be adequately guarded or  
controlled.  
d) Store idle power tools out of the reach  
of children and do not allow persons  
unfamiliar with the power tool or these  
instructions to operate the power tool.  
Power tools are dangerous in the hands of  
untrained users.  
e) Maintain power tools. Check for  
misalignment or binding of moving parts,  
breakage of parts and any other condition  
that may affect the power tool’s operation.  
If damaged, have the power tool repaired  
before use. Many accidents are caused by  
poorly maintained power tools.  
f) Keep cutting tools sharp and clean.  
Properly maintained cutting tools with sharp  
cutting edges are less likely to bind and are  
easier to control.  
g) Use the power tool, accessories and  
tool bits etc., in accordance with these  
instructions taking into account the  
f) The arbour size of wheels, flanges, backing  
pads or any other accessory must properly  
fit the spindle of the power tool. Accessories  
with arbour holes that do not match the  
mounting hardware of the power tool will run  
out of balance, vibrate excessively and may  
cause loss of control.  
g) Do not use a damaged accessory. Before  
each use inspect the accessory such as  
abrasive wheel for chips and cracks, backing  
pad for cracks, tear or excess wear, wire  
brush for loose or cracked wires. If power  
tool or accessory is dropped, inspect for  
34  
 
ENGLISH  
p) Do not use accessories that require liquid  
damage or install an undamaged accessory.  
After inspecting and installing an accessory,  
position yourself and bystanders away from  
the plane of the rotating accessory and run  
the power tool at maximum no-load speed  
for one minute. Damaged accessories will  
normally break apart during this test time.  
coolants. Using water or other liquid coolants  
may result in electrocution or shock.  
FURTHER SAFETY INSTRUCTIONS  
FOR ALL OPERATIONS  
h) Wear personal protective equipment.  
Depending on application, use face  
shield, safety goggles or safety glasses.  
As appropriate, wear dust mask, hearing  
protectors, gloves and workshop apron  
capable of stopping small abrasive or  
workpiece fragments. The eye protection must  
be capable of stopping flying debris generated  
by various operations. The dust mask or  
respirator must be capable of filtrating particles  
generated by your operation. Prolonged  
exposure to high intensity noise may cause  
hearing loss.  
Causes and Operator Prevention  
of Kickback  
Kickback is a sudden reaction to a pinched or  
snagged rotating wheel, backing pad, brush or  
any other accessory. Pinching or snagging causes  
rapid stalling of the rotating accessory which in turn  
causes the uncontrolled power tool to be forced in  
the direction opposite of the accessory’s rotation at  
the point of the binding.  
For example, if an abrasive wheel is snagged or  
pinched by the workpiece, the edge of the wheel  
that is entering into the pinch point can dig into the  
surface of the material causing the wheel to climb  
out or kick out. The wheel may either jump toward  
or away from the operator, depending on direction  
of the wheel’s movement at the point of pinching.  
Abrasive wheels may also break under these  
conditions.  
i) Keep bystanders a safe distance away from  
work area. Anyone entering the work area  
must wear personal protective equipment.  
Fragments of workpiece or of a broken  
accessory may fly away and cause injury  
beyond immediate area of operation.  
j) Hold power tool by insulated gripping  
surfaces only, when performing an operation  
where the cutting accessory may contact  
hidden wiring or its own cord. Cutting  
accessory contacting a “live” wire may make  
exposed metal parts of the power tool “live” and  
shock the operator.  
Kickback is the result of power tool 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 power tool  
and position your body and arm to allow  
you to resist kickback forces. Always use  
auxiliary handle, if provided, for maximum  
control over kickback or torque reaction  
during start-up. The operator can control  
torque reaction or kickback forces, if proper  
precautions are taken.  
k) Position the cord clear of the spinning  
accessory. If you lose control, the cord may be  
cut or snagged and your hand or arm may be  
pulled into the spinning accessory.  
l) Never lay the power tool down until the  
accessory has come to a complete stop. The  
spinning accessory may grab the surface and  
pull the power tool out of your control.  
b) Never place your hand near the rotating  
accessory. Accessory may kickback over your  
hand.  
m) Do not run the power tool while carrying it at  
your side. Accidental contact with the spinning  
accessory could snag your clothing, pulling the  
accessory into your body.  
c) Do not position your body in the area where  
power tool will move if kickback occurs.  
Kickback will propel the tool in direction  
opposite to the wheel’s movement at the point  
of snagging.  
n) Regularly clean the power tool’s air vents.  
The motor’s fan will draw the dust inside  
d) Use special care when working corners,  
sharp edges etc. Avoid bouncing and  
snagging the accessory. Corners, sharp  
edges or bouncing have a tendency to snag the  
rotating accessory and cause loss of control or  
kickback.  
the housing and excessive accumulation of  
powdered metal may cause electrical hazards.  
o) Do not operate the power tool near  
flammable materials. Sparks could ignite these  
materials.  
35  
 
ENGLISH  
e) Do not attach a saw chain woodcarving  
blade or toothed saw blade. Such blades  
create frequent kickback and loss of control.  
from the cut while the wheel is in motion  
otherwise kickback may occur. Investigate  
and take corrective action to eliminate the cause  
of wheel binding.  
Safety Warnings Specific for  
Grinding and Abrasive Cutting-Off  
Operations  
a) Use only wheel types that are recommended  
for your power tool and the specific guard  
designed for the selected wheel. Wheels for  
which the power tool was not designed cannot  
be adequately guarded and are unsafe.  
d) Do not restart the cutting operation in the  
workpiece. Let the wheel reach full speed  
and carefully reenter the cut. The wheel may  
bind, walk up or kickback if the power tool is  
restarted in the workpiece.  
e) Support panels or any oversized workpiece  
to minimise the risk of wheel pinching and  
kickback. Large workpieces tend to sag under  
their own weight. Supports must be placed  
under the workpiece near the line of cut and  
near the edge of the workpiece on both sides of  
the wheel.  
b) The guard must be securely attached to the  
power tool and positioned for maximum  
safety, so the least amount of wheel is  
exposed towards the operator. The guard  
helps to protect operator from broken wheel  
fragments and accidental contact with wheel.  
f) Use extra caution when making a “pocket  
cut” into existing walls or other blind areas.  
The protruding wheel may cut gas or water  
pipes, electrical wiring or objects that can cause  
kickback.  
c) Wheels must be used only for recommended  
applications. For example: do not grind with  
the side of cut-off wheel. Abrasive cut-off  
wheels are intended for peripheral grinding, side  
forces applied to these wheels may cause them  
to shatter.  
Additional Safety Rules  
Use of accessories not specified in this  
manual is not recommended and may be  
hazardous. Use of power boosters that would  
cause the tool to be driven at speeds greater  
than its rated speed constitutes misuse.  
d) Always use undamaged wheel flanges  
that are of correct size and shape for your  
selected wheel. Proper wheel flanges support  
the wheel thus reducing the possibility of wheel  
breakage. Flanges for cut-off wheels may be  
different from grinding wheel flanges.  
• Use clamps or another practical way to  
secure and support the workpiece to a  
stable platform. Holding the work by hand or  
against your body leaves it unstable and may  
lead to loss of control.  
e) Do not use worn down wheels from larger  
power tools. Wheel intended for larger power  
tool is not suitable for the higher speed of a  
smaller tool and may burst.  
• Always use side handle. Tighten the handle  
securely. The side handle should always be  
used to maintain control of the tool at all times.  
Additional Safety Warnings Specific  
for Abrasive Cutting-Off Operations  
a) Do not “jam” the cut-off wheel or apply  
excessive pressure. Do not attempt to make  
an excessive depth of cut. Overstressing the  
wheel increases the loading and susceptibility to  
twisting or binding of the wheel in the cut and  
the possibility of kickback or wheel breakage.  
• Avoid bouncing the wheel or giving it  
rough treatment. If this occurs, stop the tool  
and inspect the wheel for cracks or flaws.  
• Always handle and store wheels in a careful  
manner.  
• Never cut into area that may contain  
electrical wiring or piping. Serious injury may  
result.  
b) Do not position your body in line with and  
behind the rotating wheel. When the wheel,  
at the point of operations, is moving away from  
your body, the possible kickback may propel the  
spinning wheel and the power tool directly at  
you.  
• DO NOT cut metal with a diamond wheel.  
• DO NOT use abrasive wheels.  
• ALWAYS use with a dust collector.  
• Do not operate this tool for long periods of  
time. Vibration caused by the operating action  
of this tool may cause permanent injury to  
fingers, hands, and arms. Use gloves to provide  
extra cushion, take frequent rest periods, and  
limit daily time of use.  
c) When wheel is binding or when interrupting  
a cut for any reason, switch off the power  
tool and hold the power tool motionless  
until the wheel comes to a complete stop.  
Never attempt to remove the cut-off wheel
