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.  
14. Do not overreach. Keep proper footing and  
balance at all times. This enables better control  
of the power tool in unexpected situations.  
15. 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.  
16. 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.  
Battery tool use and care  
24. Recharge only with the charger specified by  
the manufacturer. A charger that is suitable for  
one type of battery pack may create a risk of fire  
when used with another battery pack.  
25. Use power tools only with specifically  
designated battery packs. Use of any other  
battery packs may create a risk of injury and fire.  
26. When battery pack is not in use, keep it away  
from other metal objects, like paper clips,  
coins, keys, nails, screws or other small metal  
objects, that can make a connection from one  
terminal to another. Shorting the battery  
terminals together may cause burns or a fire.  
27. Under abusive conditions, liquid may be  
ejected from the battery; avoid contact. If  
contact accidentally occurs, flush with water.  
If liquid contacts eyes, additionally seek  
medical help. Liquid ejected from the battery  
may cause irritation or burns.  
Power tool use and care  
17. 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.  
Service  
28. Have your power tool serviced by a qualified  
18. 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.  
19. 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.  
20. Store idle power tools out of the reach of  
children and do not allow persons unfamiliar

CORDLESS GRINDER SAFETY  
WARNINGS  
Safety Warnings Common for Grinding, Sanding,  
Wire Brushing, or Abrasive Cutting-Off Operations:  
1.  
This power tool is intended to function as  
a
grinder, sander, wire brush or 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.  
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.  
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.  
4.  
3
 
5.  
6.  
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.  
Threaded mounting of accessories must  
match the grinder spindle thread. For  
accessories mounted by flanges, the arbour  
hole of the accessory must fit the locating  
diameter of the flange. Accessories that do not  
match the mounting hardware of the power tool  
will run out of balance, vibrate excessively and  
may cause loss of control.  
12. 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.  
13. 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.  
14. Do not operate the power tool near flammable  
materials. Sparks could ignite these materials.  
15. Do not use accessories that require liquid  
coolants. Using water or other liquid coolants  
may result in electrocution or shock.  
7.  
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.  
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.  
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  
have a tendency to snag the rotating accessory  
and cause loss of control or kickback.  
10. Hold the power tool by insulated gripping  
surfaces only, when performing an operation  
where the cutting tool may contact hidden  
wiring. Contact with a "live" wire will also make  
exposed metal parts of the power tool "live" and  
could give the operator an electric shock.  
11. 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.  
e) Do not attach a saw chain woodcarving  
blade or toothed saw blade. Such blades create  
frequent kickback and loss of control.

Safety Warnings Specific for Grinding and Abrasive  
Cutting-Off Operations:  
d) Do not restart the cutting operation in the  
workpiece. Let the wheel reach full speed and  
carefully re-enter the cut. The wheel may bind,  
walk up or kickback if the power tool is restarted in  
the workpiece.  
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 grinding surface of centre depressed  
wheels must be mounted below the plane of  
the guard lip. An improperly mounted wheel that  
projects through the plane of the guard lip cannot  
be adequately protected.  
c) 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  
the operator from broken wheel fragments,  
accidental contact with wheel and sparks that  
could ignite clothing.  
d) 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.  
e) 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.  
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  
disc  
paper.  
Follow  
manufacturers  
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.  
f) 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  
16. When using depressed centre grinding  
wheels, be sure to use only fiberglass-  
reinforced wheels.  
17. NEVER USE Stone Cup type wheels with this  
grinder. This grinder is not designed for these  
types of wheels and the use of such a product  
may result in serious personal injury.  
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.

OPERATION  
WARNING:  
It should never be necessary to force the tool. The  
weight of the tool applies adequate pressure.  
Forcing and excessive pressure could cause  
dangerous wheel breakage.  
ALWAYS replace wheel if tool is dropped while  
grinding.  
NEVER bang or hit grinding disc or wheel onto  
work.  
Avoid bouncing and snagging the wheel,  
especially when working corners, sharp edges etc.  
This can cause loss of control and kickback.  
NEVER use tool with wood cutting blades and  
other sawblades. Such blades when used on a  
grinder frequently kick and cause loss of control  
leading to personal injury.  
CAUTION:  
Never switch on the tool when it is in contact with  
the workpiece, it may cause an injury to operator.  
Always wear safety goggles or a face shield during  
operation.  
After operation, always switch off the tool and wait

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.  
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.  
During cutting operations, never change the angle  
of the wheel. Placing side pressure on the cut-off  
wheel (as in grinding) will cause the wheel to crack  
and break, causing serious personal injury.  
A diamond wheel shall be operated perpendicular  
to the material being cut.  
NEVER use cut-off wheel for side grinding.  
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.

Remove the battery cartridge from the tool and place it  
upside down allowing easy access to spindle. Remove  
any accessories on spindle. Thread wire wheel brush  
onto spindle and tighten with the wrenches.  
Operation with wire cup brush  
(optional accessory)  
CAUTION:  
When using wire wheel brush, avoid applying too much  
pressure which causes over bending of wires, leading to  
premature breakage.  
Check operation of brush by running tool with no  
load, insuring that no one is in front of or in line  
with brush.  
Do not use brush that is damaged, or which is out  
of balance. Use of damaged brush could increase  
potential for injury from contact with broken brush  
wires.  
MAINTENANCE  
CAUTION:  
Always be sure that the tool is switched off and the  
battery cartridge is removed before attempting to  
perform inspection or maintenance.  
Never use gasoline, benzine, thinner, alcohol or  
the like. Discoloration, deformation or cracks may  
result.

Check operation of wire wheel brush by running  
tool with no load, insuring that no one is in front of  
or in line with the wire wheel brush.  
Do not use wire wheel brush that is damaged, or  
which is out of balance. Use of damaged wire  
wheel brush could increase potential for injury  
from contact with broken wires.  
ALWAYS use guard with wire wheel brushes,  
assuring diameter of wheel fits inside guard.  
Wheel can shatter during use and guard helps to  
reduce chances of personal injury.
