not engaged into the material. If saw blade is binding,
it may walk up or kickback from the workpiece as the saw
is restarted.
d ) Support large panels to minimise the risk of blade
pinching and kickback. Large panels tend to sag under
their own weight. Supports must be placed under the
panel on both sides, near the line of cut and near the edge
of the panel.
e ) Do not use dull or damaged blades. Unsharpened
or improperly set blades produce narrow kerf causing
excessive friction, blade binding and kickback.
f ) Blade depth and bevel adjusting locking levers
must be tight and secure before making cut. If blade
adjustment shifts while cutting, it may cause binding
and kickback.
g ) Use extra caution when making a "plunge cut" into
existing walls or other blind areas. The protruding
blade may cut objects that can cause kickback.

Safety Instructions for Plunge-Type Saws

a ) Check guard for proper closing before each use.
Do not operate the saw if guard does not move
freely and enclose the blade instantly. Never clamp
or tie the guard with the blade exposed. If saw is
accidentally dropped, guard may be bent. Check to make
sure that guard moves freely and does not touch the blade
or any other part, in all angles and depths of cut.
b ) Check the operation and condition of the guard
return spring. If the guard and the spring are not
operating properly, they must be serviced before
use. Guard may operate sluggishly due to damaged parts,
gummy deposits, or a build-up of debris.
c ) Assure that the guide plate of the saw will not shift
while performing the "plunge cut" when the blade
bevel setting is not at 90°. Blade shifting sideways will
cause binding and likely kickback.
d ) Always observe that the guard is covering the blade
before placing saw down on bench or floor. An
unprotected, coasting blade will cause the saw to walk
backwards, cutting whatever is in its path. Be aware of the
time it takes for the blade to stop after switch is released.
Additional Safety Instructions for All Saws
with Riving Knife
a ) Use the appropriate riving knife for the blade being
used. For the riving knife to work, it must be thicker than
the body of the blade but thinner than the tooth set of the
blade.
b ) Adjust the riving knife as described in this
instruction manual. Incorrect spacing, positioning
and alignment can make the riving knife ineffective in
preventing kickback.
c ) For the riving knife to work, it must be engaged in
the workpiece. The riving knife is ineffective in preventing
kickback during short cuts.
d ) Do not operate the saw if riving knife is bent. Even a
light interference can slow the closing rate of a guard.
Additional Safety Instructions for Plunge-
Type Saws
• Wear ear protectors. Exposure to noise can cause hearing
loss.
Wear a dust mask. Exposure to dust particles can cause
•
breathing difficulty and possible injury.
• Do not use blades of larger or smaller diameter than
recommended. For the proper blade rating refer to the
technical data. Use only the blades specified in this manual,
complying with EN 847-1.
• Never use abrasive cut-off wheels.

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 battery pack voltage corresponds to the
voltage on the rating plate. Also make sure that the voltage of
your charger corresponds to that of your mains.
Your D WALT charger is double insulated in
e
accordance with EN60335; 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: 3 A.

Using an Extension Cable

An extension cord should not be used unless absolutely
necessary. Use an approved extension cable suitable for
the power input of your charger (see Technical Data). The
minimum conductor size is 1 mm
is 30 m.
When using a cable reel, always unwind the cable completely.
