1. The guard provided with the tool must be

securely attached to the power tool and positioned for maximum safety, so the least amount of wheel is exposed towards the oper- ator. Position yourself and bystanders away from the plane of the rotating wheel. The guard helpstoprotectoperatorfrombrokenwheelfrag- ments and accidental contact with wheel.

2. Use only diamond cut-o󰀨 wheels for your

power tool.Justbecauseanaccessorycanbe attachedtoyourpowertool,itdoesnotassure safe operation.

3. The rated speed of the accessory must be at

least equal to the maximum speed marked on the power tool. Accessoriesrunningfasterthan theirratedspeedcanbreakandyapart.

4. Wheels must be used only for recommended

applications. For example: do not grind with the side of cut-o󰀨 wheel.Cut-o󰀨wheelsare intended for peripheral grinding, side forces appliedtothesewheelsmaycausethemto shatter.12 ENGLISH

5. Always use undamaged wheel anges that are

of correct diameter for your selected wheel. Properwheelangessupportthewheelthus reducingthepossibilityofwheelbreakage.

6. The outside diameter and the thickness of your

accessory must be within the capacity rating of your power tool.Incorrectlysizedaccessories cannotbeadequatelyguardedorcontrolled.

7. The arbour size of wheels and anges must

properly t the spindle of the power tool. Wheelsandangeswitharbourholesthatdonot match the mounting hardware of the power tool willrunoutofbalance,vibrateexcessivelyand maycauselossofcontrol.

8. Do not use damaged wheels. Before each

use, inspect the wheels for chips and cracks. If power tool or wheel is dropped, inspect for damage or install an undamaged wheel. After inspecting and installing the wheel, position yourself and bystanders away from the plane of the rotating wheel and run the power tool at maximum no load speed for one minute. Damagedwheelswillnormallybreakapartduring this test time.

Wear personal protective equipment. Depending on application, use face shield, safety goggles or safety glasses. As appropri- ate, wear dust mask, hearing protectors, gloves and shop apron capable of stopping small abrasive or workpiece fragments. Theeyepro- tectionmustbecapableofstoppingyingdebris generatedbyvariousoperations.Thedustmask orrespiratormustbecapableofltratingparticles generatedbyyouroperation.Prolongedexposure tohighintensitynoisemaycausehearingloss.

10. Keep bystanders a safe distance away from

work area. Anyone entering the work area must wear personal protective equipment. Fragmentsofworkpieceorofabrokenwheelmay yawayandcauseinjurybeyondimmediatearea of operation.

11. Hold the power tool by insulated gripping

surfaces only, when performing an operation where the cutting accessory may contact hid- den wiring.Cuttingaccessorycontactinga“live” wiremaymakeexposedmetalpartsofthepower tool“live”andcouldgivetheoperatoranelectric shock.

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

sory has come to a complete stop. The spinning wheelmaygrabthesurfaceandpullthepower tooloutofyourcontrol.

13. Do not run the power tool while carrying it at

your side.Accidentalcontactwiththespinning accessorycouldsnagyourclothing,pullingthe accessoryintoyourbody.

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 maycauseelectricalhazards.

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 mayresultinelectrocutionorshock. Kickback and related warnings Kickbackisasuddenreactiontoapinchedorsnagged rotatingwheel.Pinchingorsnaggingcausesrapid stalling of the rotating wheel which in turn causes the uncontrolledpowertooltobeforcedinthedirection opposite of the wheel’s rotation at the point of the binding. Forexample,ifawheelissnaggedorpinchedbythe workpiece, the edge of the wheel that is entering into the pinch point can dig into the surface of the material causingthewheeltoclimboutorkickout.Thewheel mayeitherjumptowardorawayfromtheoperator, depending on direction of the wheel’s movement at the pointofpinching.Wheelsmayalsobreakunderthese conditions. Kickbackistheresultofpowertoolmisuseand/or incorrectoperatingproceduresorconditionsandcanbe avoidedbytakingproperprecautionsasgivenbelow.

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- backforces,ifproperprecautionsaretaken.

2. Never place your hand near the rotating acces-

sory.Accessorymaykickbackoveryourhand.

3. Do not position your body in line with the

rotating wheel.Kickbackwillpropelthetoolin 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,sharpedgesorbouncing haveatendencytosnagtherotatingaccessory andcauselossofcontrolorkickback.

5. Do not attach a saw chain, woodcarving blade,

segmented diamond wheel with a peripheral gap greater than 10 mm (3/8") or toothed saw blade.Suchbladescreatefrequentkickbackand loss of control.

6. Do not “jam” the wheel or apply excessive

pressure. Do not attempt to make an excessive depth of cut. Overstressing the wheel increases theloadingandsusceptibilitytotwistingorbinding ofthewheelinthecutandthepossibilityofkick- backorwheelbreakage.

7. When wheel is binding or when interrupting

a cut for any reason, switch o󰀨 the power tool and hold the power tool motionless until the wheel comes to a complete stop. Never attempt to remove the wheel from the cut while the wheel is in motion otherwise kickback may occur. Investigate and take corrective action to eliminatethecauseofwheelbinding.

8. Do not restart the cutting operation in the

workpiece. Let the wheel reach full speed and carefully re-enter the cut.Thewheelmaybind, walkuporkickbackifthepowertoolisrestartedin the workpiece.

9. Support panels or any oversized workpiece to

minimize the risk of wheel pinching and kick- back. Large workpieces tend to sag under their ownweight.Supportsmustbeplacedunderthe workpiece near the line of cut and near the edge oftheworkpieceonbothsidesofthewheel.13 ENGLISH

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

into existing walls or other blind areas. The protrudingwheelmaycutgasorwaterpipes,elec- tricalwiringorobjectsthatcancausekickback. Additional Safety Warnings:

excessiveheatingmaycauseburninjury.

3. Before using a segmented diamond wheel,

make sure that the diamond wheel has the peripheral gap between segments of 10 mm (3/8") or less, only with a negative rake angle.

4. Never attempt to cut with the tool held upside

down in a vise. This can lead to serious acci- dents, because it is extremely dangerous.

5. Some material contains chemicals which may

be toxic. Take caution to prevent dust inhala- tion and skin contact. Follow material supplier safety data.

Store wheels as per manufacturer recommenda- tions. Improper storage may damage the wheels.

7. Always use the wheel suitable for your work

and the material to be cut.
