Cordless grinder safety warnings

Safety Warnings Common for Grinding, Sanding,

Wire Brushing, or Abrasive Cutting-O Operations:

1.

This power tool is intended to function as a

grinder, sander, wire brush or cut-o tool. Read

all safety warnings, instructions, illustrations

and specications 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 recom-

mended 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 specically

designed and recommended by the tool manufac-

turer. 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 accessories

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 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 maxi-

mum 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 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 ying debris generated by various operations.

The dust mask or respirator must be capable of ltrating

particles generated by your operation. Prolonged expo-

sure 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 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 ENGLISH

11. 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.

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 ammable

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.

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 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 Specic for Grinding and Abrasive

Cutting-O Operations:

1. Use only wheel types that are recommended

for your power tool and the specic 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-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. Wheel intended for larger power tool

is not suitable for the higher speed of a smaller

tool and may burst.

Additional Safety Warnings Specic for Abrasive

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 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 cut-o 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.

12 ENGLISH

Safety Warnings Specic 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 Specic 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.

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 specied surface of the wheel to per-

form the grinding.

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 specied 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 supported.

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.

17. Do not use the tool on any materials contain-

ing asbestos.

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

the dust collecting wheel guard required by

domestic regulation.

19. Cutting discs must not be subjected to any

lateral pressure.

20. Do not use cloth work gloves during operation.

Fibers from cloth gloves may enter the tool, which

causes tool breakage.

21. Make sure there are no electrical cables, water

pipes, gas pipes etc. that could cause a hazard

if damaged by use of the tool.

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 bang or hit grinding disc

or wheel onto work.

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).

Grinding and sanding operation

► Fig.25

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.

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.
