SAFETY WARNINGS General power tool safety warnings WARNING Read all safety warnings, instructions, illustrations and specications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, re and/or serious injury. Save all warnings and instruc- tions for future reference. The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool. Cordless grinder safety warnings Safety warnings common for grinding, sanding, wire brushing, or cutting-o󰀨 operations:

This power tool is intended to function as a grinder, sander, wire brush, hole cutter or cut-o󰀨 tool. Read all safety warnings, instructions, illustrations and specications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, re and/or serious injury.

2. Operations such as polishing are not to be

performed with this power tool. Operations for which the power tool was not designed may create a hazard and cause personal injury.

3. Do not convert this power tool to operate in

a way which is not specically designed and specied by the tool manufacturer. Such a con- version may result in a loss of control and cause serious personal injury.

Do not use accessories which are not specically designed and specied by the tool manufacturer. Just because the accessory can be attached to your power tool, it does not assure safe operation.

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 y apart.

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.

7. The dimensions of the accessory mounting

must t the dimensions of the mounting hard- ware of the power tool. 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.

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 acces

sories will normally break apart during this test time.

9. Wear personal protective equipment.

Depending on application, use face shield, safety goggles or safety glasses. As appro- priate, wear dust mask, hearing protectors, gloves and workshop apron capable of stop- ping small abrasive or workpiece fragments. The eye protection must be capable of stopping ying debris generated by various applications. The dust mask or respirator must be capable of ltrating particles generated by the particular application. Prolonged exposure to high intensity noise may cause hearing loss.

10. 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 y away and cause injury beyond immediate area of operation.

11. 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.

12. Never lay the power tool down until the acces-

sory 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.

15. Do not operate the power tool near ammable

materials. Sparks could ignite these materials.10 ENGLISH

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 acces- sory. Pinching or snagging causes rapid stalling of the rotating accessory which in turn causes the uncon- trolled 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 move- ment 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.

1. Maintain a rm grip with both hands on the

power tool and position your body and arms to allow you to resist kickback forces. Always use auxiliary handle, if provided, for maxi- mum control over kickback or torque reaction during start-up. The operator can control torque reactions or kickback forces, if proper precautions are taken.

2. Never place your hand near the rotating acces-

sory. Accessory may kickback over your hand.

3. 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.

4. 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.

5. Do not attach a saw chain woodcarving blade,

segmented diamond wheel with a peripheral gap greater than 10 mm or toothed saw blade. Such blades create frequent kickback and loss of control. Safety warnings specic for grinding and cutting-o󰀨 operations:

1. Use only wheel types that are specied

for your power tool and the specic guard designed for the selected wheel. Wheels for which the power tool was not designed cannot be adequately guarded and are unsafe.

2. 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.

3. 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, acci- dental contact with wheel and sparks that could ignite clothing.

Wheels must be used only for specied applica- tions. For example: do not grind with the side of cut-o󰀨 wheel. Abrasive cut-o󰀨 wheels are intended for peripheral grinding, side forces applied to these wheels may cause them to shatter.

5. Always use undamaged wheel anges that are

of correct size and shape for your selected wheel. Proper wheel anges support the wheel thus reducing the possibility of wheel breakage. Flanges for cut-o󰀨 wheels may be di󰀨erent from grinding wheel anges.

6. Do not use worn down wheels from larger

power tools. A wheel intended for larger power tool is not suitable for the higher speed of a smaller tool and may burst.

7. When using dual purpose wheels always use

the correct guard for the application being performed. Failure to use the correct guard may not provide the desired level of guarding, which could lead to serious injury. Additional safety warnings specic for cutting-o󰀨 operations:

1. Do not “jam” the cut-o󰀨 wheel or apply exces-

sive 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 possibil- ity of kickback or wheel breakage.

2. 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 spin- ning wheel and the power tool directly at you.

3. When the wheel is binding or when interrupt-

ing a cut for any reason, switch o󰀨 the power tool and hold it motionless until the wheel comes to a complete stop. Never attempt to remove the cut-o󰀨 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.

4. 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.

5. Support panels or any oversized workpiece to

minimize the risk of wheel pinching and kick- back. 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.

6. Use extra caution when making a “pocket cut”

into existing walls or other blind areas. The protruding wheel may cut gas or water pipes, elec- trical wiring or objects that can cause kickback.

7. Do not attempt to do curved cutting.

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, which can lead to serious injury.

8. Before using a segmented diamond wheel,

make sure that the diamond wheel has the peripheral gap between segments of 10 mm or less, only with a negative rake angle.11 ENGLISH Safety warnings specic for sanding operations:

1. Use proper sized sanding disc paper. Follow

manufacturers recommendations, when selecting sanding paper. Larger sanding paper extending too far beyond the sanding pad pres- ents a laceration hazard and may cause snagging, tearing of the disc or kickback. Safety warnings specic for wire brushing operations:

1. 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.

2. If the use of a guard is specied for wire

brushing, do not allow any 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:

1. When using depressed centre grinding wheels,

be sure to use only berglass-reinforced wheels.

2. 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.

3. Be careful not to damage the spindle, the

ange (especially the installing surface) or the lock nut. Damage to these parts could result in wheel breakage.

4. Make sure the wheel is not contacting the

workpiece before the switch is turned on.

5. 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.

6. Use the specied surface of the wheel to per-

7. Do not leave the tool running. Operate the tool

only when hand-held.

8. Do not touch the workpiece immediately after

operation; it may be extremely hot and could burn your skin.

9. Do not touch accessories immediately after

operation; it may be extremely hot and could burn your skin.

10. Observe the instructions of the manufacturer

for correct mounting and use of wheels. Handle and store wheels with care.

11. Do not use separate reducing bushings or

adaptors to adapt large hole abrasive wheels.

12. Use only anges specied for this tool.

13. For tools intended to be tted with threaded

hole wheel, ensure that the thread in the wheel is long enough to accept the spindle length.

14. Check that the workpiece is properly

15. Pay attention that the wheel continues to

rotate after the tool is switched o󰀨.

16. If working place is extremely hot and humid,

or badly polluted by conductive dust, use a short-circuit breaker (30 mA) to assure opera- tor safety.

18. When use cut-o󰀨 wheel, always work with

the dust collecting wheel guard if required by domestic regulation.

19. Cutting discs must not be subjected to any

20. Do not use cloth work gloves during operation.

Fibers from cloth gloves may enter the tool, which causes tool breakage.

21. Before operation, make sure that there is no

buried object such as electric pipe, water pipe or gas pipe in the workpiece. Otherwise, it may cause an electric shock, electrical leakage or gas leak.

22. If a blotter is attached to the wheel, do not

remove it. The diameter of the blotter must be larger than the lock nut, outer ange, and inner ange.

23. Before installing a grinding wheel, always

check that the blotter part does not have any abnormalities such as chips or cracks.

24. Tighten the lock nut properly. Overtightening

the wheel can cause breakage and insu󰀩cient tightening can cause uttering. SAVE THESE INSTRUCTIONS.

OPERATION

WARNING: It should never be necessary to

force the tool. The weight of the tool applies ade- quate pressure. Forcing and excessive pressure could cause dangerous wheel breakage.

WARNING: ALWAYS replace wheel if tool is

dropped while grinding.

WARNING: NEVER hit the workpiece with the

WARNING: Avoid bouncing and snagging

the wheel, especially when working corners, sharp edges etc. This can cause loss of control and kickback.

WARNING: NEVER use tool with wood cutting

blades and other saw blades. 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. CAUTION: Always wear safety goggles or a face shield during operation. CAUTION: After operation, always switch o󰀨 the tool and wait until the wheel has come to a complete stop before putting the tool down. CAUTION: ALWAYS hold the tool rmly with one hand on housing and the other on the side grip (handle). NOTE: A dual purpose wheel can be used for both grinding and cutting-o󰀨 operations. Refer to the "Grinding and sanding operation" for grinding operation, and refer to the "Operation with abrasive cut-o󰀨 / diamond wheel" for cutting-o󰀨 operation. Grinding and sanding operation ► Fig.28 Turn the tool on and then apply the wheel or disc to the workpiece. In general, keep the edge of the wheel or disc at an angle of about 15° to the workpiece surface. During the break-in period with a new wheel, do not work the grinder in forward direction or it may cut into the workpiece. Once the edge of the wheel has been rounded o󰀨 by use, the wheel may be worked in both forward and backward direction. Usage example: operation with cup-type diamond wheel ► Fig.29 Keep the tool horizontally and apply the entire cup-type diamond wheel to the workpiece surface.17 ENGLISH Operation with abrasive cut-o󰀨 / diamond wheel Optional accessory

WARNING: 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.

WARNING: 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: During cutting operations, never

change the angle of the wheel. Placing side pres- sure on the cut-o󰀨 wheel (as in grinding) will cause the wheel to crack and break, causing serious per- sonal injury.

WARNING: A diamond wheel shall be oper-

ated perpendicular to the material being cut. Usage example: operation with abrasive cut-o󰀨 wheel ► Fig.30 Usage example: operation with diamond wheel ► Fig.31 Operation with wire cup brush Optional accessory CAUTION: Check operation of brush by run- ning tool with no load, insuring that no one is in front of or in line with brush. NOTICE: Avoid applying too much pressure which causes over bending of wires when using the wire cup brush. It may lead to premature breakage. Usage example: operation with wire cup brush ► Fig.32 Operation with wire wheel brush Optional accessory CAUTION: 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. NOTICE: Avoid applying too much pressure which causes over bending of wires when using wire wheel brush. It may lead to premature breakage. Usage example: operation with wire wheel brush ► Fig.33 Operation with hole cutter Optional accessory CAUTION: Check operation of the hole cutter by running the tool with no load, insuring that no one is in front of the hole cutter. NOTICE: Do not tilt the tool during operation. It may lead to premature breakage. Usage example: operation with hole cutter ► Fig.34 MAINTENANCE CAUTION: Always be sure that the tool is switched o󰀨 and the battery cartridge is removed before attempting to perform inspection or maintenance. NOTICE: Never use gasoline, benzine, thinner, alcohol or the like. Discoloration, deformation or cracks may result.

COMBINATION OF APPLICATIONS AND

ACCESSORIES Optional accessory CAUTION: Using the tool with incorrect guards can cause risks as follows.

• When using a cut-o󰀨 wheel guard for facial grinding, the wheel guard may interfere with the work- piece causing poor control.

• When using a grinding wheel guard for cutting-o󰀨 operations with bonded abrasive wheels and dia- mond wheels, there is an increased risk of exposure to rotating wheels, emitted sparks and particles, as well as exposure to wheel fragments in the event of wheel burst.

• When using a cut-o󰀨 wheel guard or grinding wheel guard for facial operations with cup-type dia- mond wheels, the wheel guard may interfere with the workpiece causing poor control.

• When using a cut-o󰀨 wheel guard or grinding wheel guard with a wheel-type wire brush with a thick- ness greater than the maximum thickness as specied in "SPECIFICATIONS", the wires may catch on the guard leading to breaking of wires.

• Use of dust collecting wheel guards for cutting-o󰀨 and facial operations in concrete or masonry reduces a risk of exposure to dust.

• When using dual purpose (combined grinding and cutting-o󰀨 abrasive) ange mounted wheels, only use a cut-o󰀨 wheel guard.
