f ) When ripping always use a rip fence or straight edge
guide. This improves the accuracy of cut and reduces the chance
of blade binding.
g ) Always use blades with correct size and shape (diamond
versus round) of arbour holes. Blades that do not match the
mounting hardware of the saw will run eccentrically, causing loss
of control.
h ) Never use damaged or incorrect blade washers or bolt.
The blade washers and bolt were specially designed for your saw,
for optimum performance and safety of operation.
Further Safety Instructions for All Saws
Causes and operator prevention of kickback:
• kickback is a sudden reaction to a pinched, bound or misaligned
saw blade, causing an uncontrolled saw to lift up and out of the
workpiece toward the operator;
• when the blade is pinched or bound tightly by the kerf closing
down, the blade stalls and the motor reaction drives the unit
rapidly back toward the operator;
• if the blade becomes twisted or misaligned in the cut, the teeth
at the back edge of the blade can dig into the top surface of the
wood causing the blade to climb out of the kerf and jump back
toward the operator.
Kickback is the result of saw misuse and/or incorrect operating
procedures or conditions and can be avoided by taking proper
precautions as given below.
a ) Maintain a firm grip with both hands on the saw and
position your arms to resist kickback forces. Position
your body to either side of the blade, but not in line with
the blade. Kickback could cause the saw to jump backwards,
but kickback forces can be controlled by the operator, if proper
precautions are taken.
b ) When blade is binding, or when interrupting a cut for
any reason, release the trigger and hold the saw motionless
in the material until the blade comes to a complete stop.
Never attempt to remove the saw from the work or pull the
saw backward while the blade is in motion or kickback may
occur. Investigate and take corrective actions to eliminate the
cause of blade binding.
c ) When restarting a saw in the workpiece, centre the saw
blade in the kerf and check that saw teeth are 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 Saws with a Pendulum
Blade Guard
a ) Check the lower guard for proper closing before each
use. Do not operate the saw if the lower guard does not
move freely and close instantly. Never clamp or tie the lower
26
guard into the open position. If the saw is accidentally dropped,
the lower guard may be bent. Raise the lower guard with the
retracting handle and make sure it moves freely and does not
touch the blade or any other part, in all angles and depths of cut.
b ) Check the operation of the lower guard spring. If the
guard and the spring are not operating properly, they must
be serviced before use. Lower guard may operate sluggishly due
to damaged parts, gummy deposits, or a build-up of debris.
c ) The lower guard should be retracted manually only
for special cuts such as "plunge cuts" and "compound
cuts." Raise the lower guard by retracting handle and as
soon as the blade enters the material, the lower guard
must be released. For all other sawing, the lower guard should
operate automatically.
d ) Always observe that the lower 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 Circular Saws
• Do not operate the machine without guards in position, or if
guards do not function or are not maintained properly.
• Select the correct blade for the material to be cut.
• Wear a dust mask.
• 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.
• When sawing plastic, melting of the material is to be avoided.
• Please use only saw blades that are marked with a speed equal
or higher than the speed marked on the tool.

WARNING: Cutting plastics, sap coated wood, and other
materials may cause melted material to accumulate on the blade
tips and the body of the saw blade, increasing the risk of blade
overheating and binding while cutting.

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 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 only by
D WALT or an authorised service organisation.
