FURTHER SAFETY INSTRUCTIONS FOR ALL
OPERATIONS
Causes and Operator Prevention
of Kickback
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 uncontrolled 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
movement at the point of pinching. Abrasive wheels may also
break under these conditions.
Kickback is the result of 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 reaction
or kickback forces, if proper precautions are taken.
b ) 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.
c ) Do not attach a saw chain woodcarving blade or
toothed saw blade. Such blades create frequent kickback
and loss of control.
d ) Always feed the bit into the material in the same
direction as the cutting edge is exiting from the
material (which is the same direction as the chips are
thrown). Feeding the tool in the wrong direction causes
the cutting edge of the bit to climb out of the work and
pull the tool in the direction of this feed.
e ) When using rotary files, cut off wheels, high-speed
cutters or tungsten carbide cutters, always have the
work securely clamped. These wheels will grab if
they become slightly canted in the groove, and can
kickback. When a cut-off wheel grabs, the wheel itself
usually breaks. When a rotary file, high speed cutter
or tungsten carbide cutter grabs, it may jump from the
groove and you could lose control of the tool.
Safety Warnings Specific for Grinders
a ) Use only wheel types that are recommended for your
power tool and the specific guard designed for the
selected wheel. Wheels for which the power tool was not
designed cannot be adequately guarded and are unsafe.
b ) For threaded abrasive cones and plugs use only
undamaged wheel mandrels with an unrelieved
shoulder flange that are of a correct size and length.
Proper mandrels will reduce the possibility of breakage.
c ) Do not position your hand in line with or behind
a rotating wheel. When the wheel, at the point of
operation, is moving away from your hand, the possible
kickback may propel the wheel and the power tool directly
at you.
d ) 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 the cut and the edge of the workpiece on
both sides of the wheel.
Additional Safety Information
For accessories mounted by flanges, the arbor hole of the
accessory must fit the locating diameter of the flange.
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.

WARNING: We recommend the use of a residual current
device with a residual current rating of 30mA or less.
Residual Risks
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 personal injury due to flying particles.
Risk of burns due to accessories becoming hot
during operation.
Risk of personal injury due to prolonged use.
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 EN60745; 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
(U.K. & Ireland Only)
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.
