before making any adjustments, changing  
accessories, or storing power tools. Such  
preventive safety measures reduce the risk of  
starting the power tool accidentally.  
9.  
If operating a power tool in a damp location is  
unavoidable, use a residual current device  
(RCD) protected supply. Use of an RCD reduces  
the risk of electric shock.  
21. 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.  
22. 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.  
23. Keep cutting tools sharp and clean. Properly  
maintained cutting tools with sharp cutting edges  
are less likely to bind and are easier to control.  
24. Use the power tool, accessories and tool bits  
etc. in accordance with these instructions,  
taking into account the working conditions  
and the work to be performed. Use of the power  
tool for operations different from those intended  
could result in a hazardous situation.  
10. Use of power supply via a RCD with a rated  
residual current of 30mA or less is always  
recommended.  
Personal safety  
11. Stay alert, watch what you are doing and use  
common sense when operating a power tool.  
Do not use a power tool while you are tired or  
under the influence of drugs, alcohol or  
medication.  
A
moment of inattention while  
operating power tools may result in serious  
personal injury.  
12. Use personal protective equipment. Always  
wear eye protection. Protective equipment such  
as dust mask, non-skid safety shoes, hard hat, or  
hearing protection used for appropriate conditions  
will reduce personal injuries.  
13. Prevent unintentional starting. Ensure the  
switch is in the off-position before connecting  
to power source and/or battery pack, picking  
up or carrying the tool. Carrying power tools with  
your finger on the switch or energising power tools  
that have the switch on invites accidents.  
14. Remove any adjusting key or wrench before  
turning the power tool on. A wrench or a key left  
attached to a rotating part of the power tool may  
result in personal injury.  
Service  
25. 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.  
26. Follow instruction for lubricating and  
changing accessories.  
15. Do not overreach. Keep proper footing and  
balance at all times. This enables better control  
of the power tool in unexpected situations.  
16. Dress properly. Do not wear loose clothing or  
jewellery. Keep your hair, clothing, and gloves  
away from moving parts. Loose clothes,  
jewellery or long hair can be caught in moving  
parts.  
17. 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.  
27. Keep handles dry, clean and free from oil and  
grease.

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.  
Power tool use and care  
2.  
3.  
Operations such as 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.  
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.  
18. 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.  
19. 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.  
20. Disconnect the plug from the power source  
and/or the battery pack from the power tool  
3
 
4.  
5.  
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.  
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.  
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.  
Do not use a damaged accessory. Before each  
use inspect the accessory such as abrasive  
wheels 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 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.  
or snagged and your hand or arm may be pulled  
into the spinning accessory.  
12. 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.  
13. 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.  
14. Regularly clean the power tool’s air vents. The  
motor’s fan will draw the dust inside the housing  
and excessive accumulation of powdered metal  
may cause electrical hazards.  
6.  
7.  
15. Do not operate the power tool near flammable  
materials. Sparks could ignite these materials.  
16. Do not use accessories that require liquid  
coolants. Using water or other liquid coolants may  
result in electrocution or shock.  
Kickback and Related Warnings  
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.  
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 reactions or  
kickback forces, if proper precautions are taken.  
b) Never place your hand near the rotating  
accessory. Accessory may kickback over your  
hand.  
8.  
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.  
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.  
9.  
10. 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.  
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.  
d) Use special care when working corners,  
sharp edges etc. Avoid bouncing and snagging  
the accessory. Corners, sharp edges or bouncing  
11. Position the cord clear of the spinning  
accessory. If you lose control, the cord may be cut

have a tendency to snag the rotating accessory and  
cause loss of control or kickback.  
e) Do not attach a saw chain woodcarving  
blade or toothed saw blade. Such blades create  
frequent kickback and loss of control  
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.  
Safety Warnings Specific for Grinding and Abrasive  
Cutting-Off Operations:  
e) Support panels or any oversized workpiece  
to minimize 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.  
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.  
Safety Warnings Specific for Sanding Operations:  
a) Do not use excessively oversized sanding  
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.  
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.  
disc  
paper.  
Follow  
manufacturers  
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.  
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.  
recommendations, when selecting sanding  
paper. Larger sanding paper extending beyond the  
sanding pad presents a laceration hazard and may  
cause snagging, tearing of the disc or kickback.  
Safety Warnings Specific for Wire Brushing  
Operations:  
a) Be aware that wire bristles are thrown by the  
brush even during ordinary operation. Do not  
overstress the wires by applying excessive  
load to the brush. The wire bristles can easily  
penetrate light clothing and/or skin.  
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.  
b) If the use of a guard is recommended for  
wire brushing, do not allow interference of the  
wire wheel or brush with the guard. Wire wheel  
or brush may expand in diameter due to work load  
and centrifugal forces.  
Additional Safety Warnings Specific for Abrasive  
Cutting-Off Operations:  
Additional safety warnings:  
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.  
b) Do not position your body in line with and  
behind the rotating wheel. When the wheel, at  
the point of operation, is moving away from your  
body, the possible kickback may propel the  
spinning wheel and the power tool directly at you.  
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 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  
17. When using depressed centre grinding wheels,  
be sure to use only fiberglass-reinforced  
wheels.  
18. Be careful not to damage the spindle, the  
flange (especially the installing surface) or the  
lock nut. Damage to these parts could result in  
wheel breakage.  
19. Make sure the wheel is not contacting the  
workpiece before the switch is turned on.  
20. Before using the tool on an actual workpiece,  
let it run for a while. Watch for vibration or  
wobbling that could indicate poor installation  
or a poorly balanced wheel.  
21. Use the specified surface of the wheel to  
perform the grinding.  
22. Watch out for flying sparks. Hold the tool so  
that sparks fly away from you and other  
persons or flammable materials.  
23. Do not leave the tool running. Operate the tool  
only when hand-held.

WARNING:  
When using an abrasive cut-off / diamond wheel,  
be sure to use only the special wheel guard  
designed for use with cut-off wheels.  
MAINTENANCE  
NEVER use cut-off wheel for side grinding.  
CAUTION:  
Do not "jam" the 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, wheel  
breakage and overheating of the motor may occur.  
Do not start the cutting operation in the workpiece.  
Let the wheel reach full speed and carefully enter  
into the cut moving the tool forward over the  
workpiece surface. The wheel may bind, walk up  
or kickback if the power tool is started in the  
workpiece.  
Always be sure that the tool is switched off and  
unplugged before attempting to perform inspection  
or maintenance.  
Never use gasoline, benzine, thinner, alcohol or the  
like. Discoloration, deformation or cracks may
