English

•  Do not cut wood, plastic or synthetic materials.
•  Do not cut cast-iron materials.
•  Never cut magnesium materials.
•  Do not cut electrically live material.
•  Use this tool in a well-ventilated area. Do not operate the 

tool near flammable liquids, gases or dust. Sparks or hot 
chips from cutting or arcing motor brushes may ignite 
combustible materials.

•  Regularly clear the ventilation slots when working in dusty 

conditions. If it should become necessary to clean the slots, 
always use a soft brush; remember to unplug the machine first.

•  Always store cutting discs well-protected and in a dry place, 

out of reach of children.

•  Check damaged parts. Before further use of the tool, a guard 

or other part that is damaged should be carefully checked 
to determine that it will operate properly and perform its 
intended function—check for alignment of moving parts, 
binding of moving parts, breakage of parts, mounting, and 
any other conditions that may affect its operation. A guard 
or other part that is damaged should be properly repaired 
or replaced.

Residual Risks

•  The following risks are inherent to the use of these machines:

 

ʵ injuries caused by touching the rotating parts.

 

ʵ injuries caused by disruption of the cutting disc.

•  These risks are most evident:

 

ʵ within the range of operation

 

ʵ within the range of the rotating machine parts

•  In spite of the application of the relevant safety regulations 

and the implementation of safety devices, certain residual risks 
cannot be avoided. These are:

 

ʵ Impairment of hearing.

 

ʵ Risk of accidents caused by the uncovered parts of the 

rotating cutting disc.

 

ʵ Risk of injury when changing the disc.

 

ʵ Risk of squeezing fingers when opening the guards.

Electrical Safety

The electric motor has been designed for one voltage only. 
Always check that the power supply corresponds to the voltage 
on the rating plate.

Your 

D

e

WALT

 tool is double insulated in accordance 

with EN62841; therefore no earth wire is required.

 

WARNING:

 115 V units have to be operated via a fail-safe 

isolating transformer with an earth screen between the 
primary and secondary winding.

If the supply cord is damaged, it must be replaced by a 
specially prepared cord available through the

service organisation.

Mains Plug Replacement 
(U.K. & Ireland Only)

If a new mains plug needs to be fitted:

susceptibility to twisting or binding of the wheel in the cut 
and the possibility of kickback or wheel breakage.

e ) 

When the wheel is binding or when interrupting a 
cut for any reason, switch off the power tool and 
hold the cutting unit 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 eliminate the cause of wheel binding.

f ) 

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.

g ) 

Support 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.

Additional Safety Warnings for Chop Saws

•  In operation, avoid bouncing the cutting disc or giving it 

rough treatment. If this occurs, stop the tool and inspect the 
cutting disc.

•  Do not operate the tool while standing in line with the cutting 

disc. Keep other persons away from the work area.

•  Be aware of cutting chips and the material being cut. 

They may be sharp and hot. Allow cut off parts to cool 
before handling.

•  The spark deflector becomes hot during use. Avoid touching or 

adjusting the spark deflect or immediately after operation.

•  Switch off the tool and wait for the cutting disc to stop before 

moving the workpiece or changing the settings.

•  After switching off, never attempt to stop the cutting disc by 

pressing against the side of the disc.

•  Do not use cutting fluids. These fluids could ignite or cause 

electrical shock.

•  Check that the workpiece is properly supported.
•  Use the cutting discs recommended by the manufacturer only. 

Do not use tools for purposes not intended; for example do not 
use circular saw blade to cut tree limbs or logs.

•  The max. allowable speed of the cutting disc must always be 

equal to or greater than the no-load speed of the tool specified 
on the nameplate.

•  Do not use cutting discs that do not conform to the 

dimensions stated in the 

Technical Data

.

•  Read the operating instructions supplied by the 

wheel manufacturer.

•  Ensure that the abrasive wheel is correctly fitted and tightened 

before use.

•  Let the tool run at no-load in a safe position for at least 

30 seconds. If there is a considerable vibration or if any 
other defect occurs, stop the tool and check it to determine 
the cause.

•  Do not use cutting discs for side grinding.
•  Do not cut concrete, brick, tile or ceramic materials.
