DO NOT OPERATE THIS TOOL NEAR FLAMMABLE
•
LIQUIDS, GASES OR DUST. Sparks or hot chips from cutting
or arcing motor brushes may ignite combustible materials.
• 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
1 minute. If there is a considerable vibration or if any other
defect occurs, stop the tool and check it to determine
the cause.
• Ensure that ventilation slots are kept clear when working in
dusty conditions. First disconnect the machine from the mains
supply then clean the openings by using a soft brush.
• Do not use the side of the abrasive wheel as a deburring
grinder. This will substantially weaken the wheel creating an
unsafe condition. The wheel may come apart.
• The wheel continues to rotate after the machine is
switched off.

WARNING: Wear appropriate hearing protection
during use. Under some conditions and duration of use,
noise from this product may contribute to hearing loss.

CAUTION: Spark deflector will get hot. Avoid touching
or adjusting while hot. Keep cordset and materials away
from spark deflector.
• Avoid prolonged contact with dust from cutting
activity Wear protective clothing and wash exposed
areas with soap and water. Allowing dust to get into your
mouth, eyes, or lay on the skin may promote absorption of
harmful chemicals.
• Do not use toothed blades.
• Always store cutting discs well-protected and in a dry place,
out of reach of children.
• Do not expose to rain or use in damp locations.
• Only use chop saw wheel of a max. thickness of
3.0 mm and a max. diameter of 355 mm.

WARNING: We recommend the use of a residual current
device with a residual current rating of 30mA or less.
Residual Risks
The following risks are inherent to the use of these machines:
• Injuries caused by touching the rotating parts.
• Injuries caused by disruption of the cutting disc.
These risks are most evident:
• Within the range of operation.
• 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:
• Impairment of hearing.
• Risk of accidents caused by the uncovered parts of the rotating
cutting disc.
• Risk of injury when changing the disc.
• 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 WALT tool is double insulated in accordance
e
with EN62841; therefore no earth wire is required.
If the supply cord is damaged, it must be replaced by a
specially prepared cord available through the D
service organisation.
Mains Plug Replacement
(Middle East and Africa)
If a new mains plug needs to be fitted:
• Safely dispose of the old plug.
• Connect the brown lead to the live terminal in the plug.
• Connect the blue lead to the neutral terminal.

WARNING: No connection is to be made to the
earth terminal.
Follow the fitting instructions supplied with good quality plugs.
Recommended fuse: 13 A.

Using an Extension Cable

If an extension cable is required, use an approved 3–core
extension cable suitable for the power input of this tool (see
Technical Data). The minimum conductor size is 1.5 mm
maximum length is 30 m.
When using a cable reel, always unwind the cable completely.

Voltage Drops

Inrush currents cause short-time voltage drops. Under
unfavourable power supply conditions, other equipment may
be affected.
If the system impedance of the power supply is lower than
0.11 Ω, disturbances are unlikely to occur.

Power Supply

Be sure your power supply agrees with the nameplate marking.
A voltage decrease of more than 10% will cause a loss of power
and overheating.
