c) 

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.

d) 

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.

e) 

Do not overreach. Keep proper footing and balance at all times.

This enables better control of the power tool in unexpected situa-

tions.

f) 

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.

g) 

If devices are provided for the connection of dust extraction 

and collection facilities, ensure these are connected and prop‑

erly used.

 Use of dust collection can reduce dust-related hazards.

4)  Power tool use and care

a) 

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.

b) 

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.

c) 

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 acciden-

tally.

d) 

Store idle power tools out of the reach of children and do not 

allow persons unfamiliar with the power tool or these instruc‑

tions to operate the power tool.

 Power tools are dangerous in the 

hands of untrained users.

e) M

aintain 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.

f) 

Keep cutting tools sharp and clean.

 Properly maintained cutting 

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

to control..

g) 

Use the power tool, accessories and tool bits etc. in accordance 

with these instructions, taking into account the working con‑

ditions and the work to be performed.

 Use of the power tool for 

operations different from those intended could result in a hazard-

ous situation.

5) Service

a) 

Have your power tool serviced by a qualified repair person us‑

ing only identical replacement parts.

 This will ensure that the 

safety of the power tool is maintained.

Special Safety Instructions

Collective Safety Warnings for Grinding, 

Sanding, Wire Brushing and Abrasive Cutting‑

Off Operations:

a) 

This power tool is intended to function as a  grinder, sander, 

wire brush and cut‑off tool. Read all safety warnings, instruc‑

tions, illustrations and specifications provided with this power 

tool.

 Failure to follow all the instructions may result in electric 

shock, fire and/or serious injury.

b) 

This power tool is not suitable for polishing work.

 Operations 

for which the power tool was not designed may create a hazard 

and cause personal injury.

c) 

Do not use accessories which are not specifically designed and 

recommended by the tool manufacturer.

 Just because the acces-

sory can be attached to your power tool, it does not assure safe 

operation.

d) 

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.

e) 

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.

f) 

The arbour size of wheels, flanges, backing pads or any other 

accessory must properly fit the spindle of the power tool.

 Ac-

cessories with arbour holes that do not match the mounting hard-

ware of the power tool will run out of balance, vibrate excessively 

and may cause loss of control.

g) 

Do not use a damaged accessory. Before each use inspect the 

accessories such as abrasive wheels for chips and cracks, back‑

ing pads for cracks, tear or excess wear, wire brushes for loose 

or cracked wires. If power tool or accessory is dropped, inspect 

for damage or install an undamaged accessory. After inspect‑

ing and installing an accessory, position yourself and bystand‑

ers away from the plane of the rotating accessory and run the 

power tool at maximum no‑load speed for one minute.

 Dam-

aged accessories will normally break apart during this test time.

h) 

Wear personal protective equipment. Depending on the ap‑

plication, use face shield, safety goggles or safety glasses. As 

appropriate, wear a dust mask, hearing protectors, gloves and 

a workshop apron capable of stop‑ping small abrasive or work‑

piece fragments.

 The eye protection must be capable of stopping 

flying debris generated by various operations. The dust mask or 

respirator must be capable of filtering particles generated by your 

operation. Prolonged exposure to high intensity noise may cause 

hearing loss.

i) 

Keep bystanders a safe distance away from work area. Anyone 

entering the work area must wear personal protective equip‑

ment.

 Fragments of workpiece or of a broken accessory may fly 

away and cause injury beyond immediate area of operation.

j) 

Hold the power tool by insulated gripping surfaces only when 

performing an operation where the cutting accessory may con‑

tact hidden wiring or its own cord.

 Cutting accessory contacting 

a “live” wire may make exposed metal parts of the power tool “live” 

and shock the operator.

k) 

Position the cord clear of the spinning accessory.

 If you lose con-

trol of the power tool, the cord may be cut or snagged and your 

hand or arm may be pulled into the spinning accessory.

l) 

Never lay the power tool down until the accessory has come to 

a complete stop.

 The spinning accessory may catch the surface 

and pull the power tool out of your control.

m) 

Do not run the power tool while carrying it at your side.

 Acci-

dental contact with the spinning accessory could snag your cloth-

ing, pulling the accessory into your body.

n) 

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.

o) 

Do  not operate the power tool near flammable materials.

Sparks could ignite these materials.

p) 

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 accessory. 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 accesso-

ry’s rotation at the point of the binding.
For example, if an abrasive wheel is snagged or pinched by the work-

piece, 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, de-

pending 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 precau-

tions 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. Always use an 

auxiliary handle, if provided, for maximum control over kick‑

back or torque reaction during start‑up.

 The operator can con-

trol torque reactions or kick-back forces, if proper precautions are 

taken.

b) 

Never place your hand near the rotating accessory.

 Accessory 

may kickback over your hand.

c) 

Do  not position your body in the area where power tool will 

move if kickback occurs.

 Kick-back will propel the tool in direction 

opposite to the wheel’s movement at the point of snagging.

d) 

Take 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.
