Save all warnings and instructions for future reference. 

CUT-OFF MACHINE SAFETY WARNINGS

a) 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 operator. Position yourself and bystanders away 

from the plane of the rotating wheel. 

The guard helps to 

protect operator from broken wheel fragments and acciden

-

tal contact with wheel.

b) 

Use only bonded reinforced or diamond cut-off 

wheels for your power tool. 

Just because an accessory 

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

operation.

c) 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.

d) Wheels must be used only for recommended applica-

tions. 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.

e) 

Always use undamaged wheel flanges that are of 

correct diameter for your selected wheel.

 Proper wheel 

flanges support the wheel thus reducing the possibility of 

wheel breakage.

f)  Do not use worn down reinforced wheels from larger 

power tools. 

Wheels intended for a larger power tool are 

not suitable for the higher speed of a smaller tool and may 

burst.

g) The outside diameter and the thickness of your 

accessory must be within the capacity rating of your 

power tool.

 Incorrectly sized accessories cannot be ade

-

quately guarded or controlled.

h) 

The arbour size of wheels and flanges must properly 

fit the spindle of the power tool.

 Wheels and flanges with 

arbour holes that do not match the mounting hardware of 

the power tool will run out of balance, vibrate excessively 

and may cause loss of control.

i)  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.

 Damaged 

wheels will normally break apart during this test time.

j)  Wear personal protective equipment. Depending on 

application, use face shield, safety goggles or safety 

glasses. As appropriate, wear dust mask, hearing 

protectors, gloves and shop apron capable of stopping 

small abrasive or workpiece fragments.

 The eye protec

-

tion 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.

WARNING

The vibration emission level given in this information sheet has been measured in accordance with a standardised test given 

in EN 60745 and may be used to compare one tool with another. It may be used for a preliminary assessment of exposure.
The declared vibration emission level represents the main applications of the tool. However if the tool is used for different 

applications, with different accessories or poorly maintained, the vibration emission may differ. This may significantly increase 

the exposure level over the total working period.
An estimation of the level of exposure to vibration should also take into account the times when the tool is switched off or 

when it is running but not actually doing the job. This may significantly reduce the exposure level over the total working period.
Identify additional safety measures to protect the operator from the effects of vibration such as: maintain the tool and the 

accessories, keep the hands warm, organisation of work patterns.

k) Keep bystanders a safe distance away from work 

area. Anyone entering the work area must wear per-

sonal protective equipment. 

Fragments of workpiece or 

of a broken wheel may fly away and cause injury beyond 

immediate area of operation.

l)  Hold the power tool by insulated gripping surfaces 

only, when performing an operation where the cutting 

accessory may contact hidden wiring or its own cord.

Cutting accessory contacting a „live“ wire may make expo

-

sed metal parts of the power tool „live“ and could give the 

operator an electric shock.

m) Position the cord clear of the spinning accessory.

 If 

you lose control, the cord may be cut or snagged and your 

hand or arm may be pulled into the spinning accessory.

n) Never lay the power tool down until the accessory 

has come to a complete stop. 

The spinning wheel may 

grab the surface and pull the power tool out of your control.

o) 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.

p) Regularly clean the power tool’s air vents.

 The 

motor’s fan will draw the dust inside the housing and exces

-

sive accumulation of powdered metal may cause electrical 

hazards.

q) 

Do not operate the power tool near flammable mate

-

rials. 

Sparks could ignite these materials.

r)  Do not use accessories that require liquid coolants.

Using water or other liquid coolants may result in electrocut

-

ion or shock.

operations 

Kickback and related warnings

Kickback is a sudden reaction to a pinched or snagged 

rotating wheel. Pinching or snagging causes rapid stalling of 

the rotating wheel which in turn causes the uncontrolled 

power tool to be forced in the direction opposite of the 

wheel’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 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. Always use auxiliary handle, if provided, for 

maximum control over kickback or torque reaction 

during start-up.

 The operator can control torque reactions 

or kickback 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 line with the rotating 

wheel. 

Kickback will propel the tool in direction opposite to 

the wheel’s movement at the point of snagging.

d) Use special care when working corners, sharp edges 

etc. Avoid bouncing and snagging the accessory.

 Cor-

ners, sharp edges or bouncing have a tendency to snag the 

rotating accessory and cause loss of control or kickback.

e) Do not attach a saw chain, woodcarving blade, 

segmented diamond wheel with a peripheral gap greater 

than 10 mm or toothed saw blade. 

Such blades create 

frequent kickback and loss of control.

f)  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 suscep

-

tibility to twisting or binding of the wheel in the cut and the 

possibility of kickback or wheel breakage.

g) When wheel is binding or when interrupting a cut for 

any reason, switch off the power tool and hold the pow

-

er 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 oc-

cur. 

Investigate and take corrective action to eliminate the 

cause of wheel binding.

h) 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.

i)  Support panels or any oversized workpiece to 

minimize the risk of wheel pinching and kickback. 

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.

j)  Use extra caution when making a “pocket cut” into 

existing walls or other blind areas.

 The protruding wheel 

may cut gas or water pipes, electrical wiring or objects that 

can cause kickback.

ADDITIONAL SAFETY AND WORKING INSTRUCTIONS

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.
Use protective equipment. Always wear safety glasses when 

working with the machine. The use of protective clothing is 

recommended, such as dust mask, protective gloves, sturdy 

non-slip footwear, helmet and ear defenders.

WARNING

 To reduce the risk of injury in applications that 

produce a considerable amount of dust, use a Milwaukee 

dust extraction solution in accordance with the solution’s 

operating instructions.  
The dust produced when using this tool may be harmful to 

health. Do not inhale the dust. Wear a suitable dust 

protection mask.
Do not machine any materials that present a danger to 

health (e.g. asbestos).
Switch the device off immediately if the insertion tool stalls! 

Do not switch the device on again while the insertion tool is 

stalled, as doing so could trigger a sudden recoil with a high 

reactive force. Determine why the insertion tool stalled and 

rectify this, paying heed to the safety instructions.
The possible causes may be:

• 

it is tilted in the workpiece to be machined

• 

it has pierced through the material to be machined

• 

the power tool is overloaded

Do not reach into the machine while it is running.
The insertion tool may become hot during use.

•  when changing tools

• 

when setting the device down

When working in walls ceiling, or floor, take care to avoid 

electric cables and gas or waterpipes.
