WARNING: Read all safety warnings and

all instructions. Failure to follow the warnings and instructions 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. 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, illus- trations 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 rec-

ommended to be performed with this power tool. Operations for which the power tool was not designed may create a hazard and cause per- sonal injury.

3. Do not use accessories which are not speci-

cally 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 y 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 guarded or controlled.

6. Threaded mounting of accessories must

match the grinder spindle thread. For acces- sories mounted by anges, the arbour hole of the accessory must t the locating diameter of the ange. 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. 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 acces- sory 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.

8. 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 operations. The dust mask or respirator must be capable of ltrating particles generated by your operation. Prolonged exposure to high intensity noise may cause hearing loss.

9. 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.

10. Hold the power tool by insulated gripping

surfaces only, when performing an operation where the cutting accessory may contact hid- den wiring or its own cord. Cutting accessory contacting a "live" wire may make exposed metal parts of the power tool “live” and could give the operator an electric shock.

11. Position the cord clear of the spinning acces-

sory. If you lose control, the cord may be cut or snagged and your hand or arm may be pulled into the spinning accessory.

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.

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’s7 ENGLISH 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.

1. Maintain a rm 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 kick- back 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

or toothed saw blade. Such blades create fre- quent kickback and loss of control. Safety Warnings Specic for Grinding and Abrasive Cutting-Off Operations:

1. Use only wheel types that are recommended

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.

4. 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.

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-off wheels may be different from grinding wheel anges.

6. 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. Additional Safety Warnings Specic for Abrasive Cutting-Off Operations:

1. Do not “jam“ the cut-off 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 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 correc- tive 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. Safety Warnings Specic for Sanding Operations:

1. Do not use excessively oversized sanding

disc paper. Follow manufacturers recommen- dations, 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 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 recommended 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.8 ENGLISH

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. Observe the instructions of the manufacturer

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

10. Do not use separate reducing bushings or

adaptors to adapt large hole abrasive wheels.

11. Use only anges specied for this tool.

12. 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.

13. Check that the workpiece is properly

14. Pay attention that the wheel continues to

rotate after the tool is switched off.

15. 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.

17. When use cut-off wheel, always work with

the dust collecting wheel guard required by domestic regulation.

18. Cutting discs must not be subjected to any

19. Do not use cloth work gloves during operation.

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

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: 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 off 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 handle. Grinding and sanding operation ►Fig.11 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 off by use, the wheel may be worked in both forward and backward direction. Operation with abrasive cut-off / diamond wheel Optional accessory

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. (In some European countries, when using a diamond wheel, the ordinary guard can be used. Follow the regulations in your country.)

WARNING: NEVER use cut-off wheel for side

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.

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.

WARNING: A diamond wheel shall be oper-

ated perpendicular to the material being cut. ► Fig.12: 1. Lock nut 2. Abrasive cut-off wheel / dia- mond wheel 3. Inner ange 4.
