Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury. Save all warnings and instructions for future reference. The term "power tool" in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool. Work area safety

1. Keep work area clean and well lit. Cluttered or

dark areas invite accidents.

2. Do not operate power tools in explosive

atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.

3. Keep children and bystanders away while

operating a power tool. Distractions can cause you to lose control. Electrical Safety

4. Power tool plugs must match the outlet. Never

modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.

5. Avoid body contact with earthed or grounded

surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

6. Do not expose power tools to rain or wet

conditions. Water entering a power tool will increase the risk of electric shock.

7. Do not abuse the cord. Never use the cord for

carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.

8. When operating a power tool outdoors, use an

extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.

9. If operating a power tool in a damp location is

unavoidable, use a ground fault circuit interrupter (GFCI) protected supply. Use of an GFCI reduces the risk of electric shock. Personal Safety

10. 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.

11. 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.

12. 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.

13. 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.3

14. Do not overreach. Keep proper footing and

balance at all times. This enables better control of the power tool in unexpected situations.

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.

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. 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.

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 with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.

21. 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.

22. Keep cutting tools sharp and clean. Properly

maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

23. 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. 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.

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. Service

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.

29. Follow instruction for lubricating and

changing accessories.

30. Keep handles dry, clean and free from oil and

SAFETY WARNINGS Safety Warnings Common for Grinding Operation:

This power tool is intended to function as a grinder. 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.

Operations such as sanding, wire brushing, polishing or cutting-off 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.

3. 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.

4. 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.

5. 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 controlled.

6. The arbour size of accessories must properly

fit the collet 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.

7. Mandrel mounted accessories must be fully

inserted into the collet or chuck. If the mandrel is insufficiently held and/or the overhang of the4 wheel is too long, the mounted accessory may become loose and be ejected at high velocity

8. Do not use a damaged accessory. Before each

use inspect the accessory such as abrasive wheels for chips and cracks. 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.

9. 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.

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. Always hold the tool firmly in your hand(s)

during the start-up. The reaction torque of the motor, as it accelerates to full speed, can cause the tool to twist.

13. Use clamps to support workpiece whenever

practical. Never hold a small workpiece in one hand and the tool in the other hand while in use. Clamping a small workpiece allows you to use your hand(s) to control the tool. Round material such as dowel rods, pipes or tubing have a tendency to roll while being cut, and may cause the bit to bind or jump toward you.

14. 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.

15. After changing the bits or making any

adjustments, make sure the collet nut, chuck or any other adjustment devices are securely tightened. Loose adjustment devices can unexpectedly shift, causing loss of control, loose rotating components will be violently thrown.

16. 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.

17. 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.

18. Do not operate the power tool near flammable

materials. Sparks could ignite these materials.

19. 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 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. 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. The operator can control kickback forces, if proper precautions are taken. b) 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. c) Do not attach a toothed saw blade. Such blades create frequent kickback and loss of control d) Always feed the bit into the material in the same direction as the cutting edge is exiting from the material (which is the same direction as the chips are thrown). Feeding the tool in the wrong direction causes the cutting edge of the bit to climb out of the work and pull the tool in the direction of this feed. Safety Warnings Specific for Grinding: a) Use only wheel types that are recommended for your power tool and only for recommended applications.5 Additional safety warnings:

The tool is intended for use with bonded abrasive wheel points (grinding stones) permanently mounted on plain, unthreaded mandrel (shanks).

21. Make sure the wheel is not contacting the

workpiece before the switch is turned on.

22. 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.

23. Use the specified surface of the wheel to

perform the grinding.

24. Watch out for flying sparks. Hold the tool so

that sparks fly away from you and other persons or flammable materials.

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

only when hand-held.

26. Do not touch the workpiece immediately after

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

27. Observe the instructions of the manufacturer

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

Check that the workpiece is properly supported.

29. If working place is extremely hot and humid,

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

31. Always be sure you have a firm footing. Be

sure no one is below when using the tool in high locations. SAVE THESE INSTRUCTIONS.

• Always be sure that the tool is switched off and the battery cartridge is removed before adjusting or checking function on the tool. Installing or removing battery cartridge

• Always switch off the tool before installing or removing of the battery cartridge.
• Hold the tool and the battery cartridge firmly when installing or removing battery cartridge. Failure to hold the tool and the battery cartridge firmly may cause them to slip off your hands and result in damage to the tool and battery cartridge and a personal injury. To remove the battery cartridge, slide it from the tool while sliding the button on the front of the cartridge. To install the battery cartridge, align the tongue on the battery cartridge with the groove in the housing and slip it into place. Insert it all the way until it locks in place with a little click. If you can see the red indicator on the upper side of the button, it is not locked completely. CAUTION:
• Always install the battery cartridge fully until the red indicator cannot be seen. If not, it may accidentally fall out of the tool, causing injury to you or someone around you.

• Do not install the battery cartridge forcibly. If the cartridge does not slide in easily, it is not being inserted correctly. Battery protection system The tool is equipped with a battery protection system. This system automatically cuts off power to the motor to extend battery life. The tool will automatically stop during operation if the tool and/or battery are placed under one of the following conditions:

• Overloaded: The tool is operated in a manner that causes it to draw an abnormally high current. In this situation, turn the tool off and stop the application that caused the tool to become overloaded. Then turn the tool on to restart. If the tool does not start, the battery is overheated. In this situation, let the battery cool before turning the tool on again.
• Low battery voltage: The remaining battery capacity is too low and the tool will not operate. In this situation, remove and recharge the battery. NOTE: The overheat protection works only with a battery cartridge with a star mark.

• Before installing the battery cartridge into the tool, always check to see that the slide switch actuates properly and returns to the "OFF" position when the rear of the slide switch is depressed.
• Switch can be locked in "ON" position for ease of operator comfort during extended use. Apply caution when locking tool in "ON" position and maintain firm grasp on tool. To start the tool, slide the slide switch toward the "I (ON)" position. For continuous operation, press the front of the slide switch to lock it. To stop the tool, press the rear of the slide switch, then slide it toward the "O (OFF)" position.

Indication lamp with multi function

Indication lamps are located in two positions. When the battery cartridge is inserted on the tool with the slide switch positioned in the "O (OFF)" position, the indication lamp flickers quickly for approximately one second. If it does not flicker so, the battery cartridge or indication lamp is broken. − Overload protection − When the tool is overloaded, the indication lamp lights up. When the load on the tool is reduced, the lamp goes out. − If the tool continues to be overloaded and the indication lamp continues to light up for approximately two seconds, the tool stops. This prevents the motor and its related parts from being damaged. − In this case, to start the tool again, move the slide switch to the "O (OFF)" position once and then to the "I (ON)" position. − Battery cartridge replacing signal − When the remaining battery capacity gets low, the indicator lamp lights up during operation signaling that it is time to change the battery. − Accidental re-start preventive function − Even if the battery cartridge is inserted on the tool with the slide switch in the "I (ON)" position, the tool does not start. At this time, the lamp flickers slowly and this shows that the accidental re-start preventive function is at work. − To start the tool, first slide the slide switch toward the "O (OFF)" position and then slide it toward the "I (ON)" position.

• Always be sure that the tool is switched off and the battery cartridge is removed before carrying out any work on the tool. Installing or removing wheel point

Loosen the collet nut and insert the wheel point into the collet nut. Use one wrench to hold the spindle and the other one to tighten the collet nut securely. The wheel point should not be mounted more than 8 mm (5/16") from the collet nut. Exceeding this distance could cause vibration or a broken shaft. To remove the wheel point, follow the installation procedure in reverse. 8 mm (5/16") Max.

• A 1/4" collet cone is provided as standard equipment. Use an optional collet cone 1/8" to install a 1/8" shank wheel point. OPERATION

Turn the tool on without the wheel point making any contact with the workpiece and wait until the wheel point

reaches maximum speed. Then apply the wheel point to the workpiece gently. To obtain a good finish, move the tool in the leftward direction slowly. CAUTION:

• Apply light pressure on the tool. Excessive pressure on the tool will only cause a poor finish and overloading of the motor. 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. Replacing carbon brushes
