WARNING: To reduce the risk of serious personal injury, turn
tool off and disconnect battery pack before making any
adjustments or removing/installing attachments or accessories.
An accidental start-up can causeinjury.
Ensure the machine is placed to satisfy your ergonomic conditions in terms
of table height and stability. The machine site shall be chosen so that the
operator has a good overview and enough free surrounding space around
the machine that allows handling of the workpiece without anyrestrictions.
To reduce effects of increased vibration, make sure the environment is not
too cold, the machine and accessory are well maintained and the workpiece
size is suitable for thismachine.
Switching On and Off (Fig.A)
The lock off switch
28
located on the the on/off trigger switch
1
must be
flipped in order for the saw to turnon.
1. To run the tool, flip the lock off switch
28
and press the on/off trigger
switch
1
.
2. To stop the tool, release thetrigger switch. The lock off switch will
re-engageautomatically.
Use of XPS LED Worklight System (Fig.A,B, N)
NOTE: The mitre saw must have the battery installed for the XPS LED
worklight tooperate.
The XPS LED Worklight System is activated by engaging the trigger or
pressing the XPS button on top of the saw housing.
To cut through an existing pencil line on a piece ofwood:
1. With the XPS light on, pull down on the operating handle to bring the
saw blade
7
close to the wood. The shadow of the blade will appear
on thewood.
2. Align the pencil line with the edge of the blade’s shadow. You may
have to adjust the mitre or bevel angles in order to match the pencil
lineexactly.
Your saw is equipped with a battery fault feature. The XPS worklight
begins to flash when the battery is near the end of its useful charge, or
when the battery is too hot. Charge the battery prior to continuing cutting
applications. Refer to Charging A Battery for battery charginginstructions.
Body and Hand Position (Fig. O)
Proper positioning of your body and hands when operating the mitre saw
will make cutting easier, more accurate andsafer.

WARNING:
• Never place your hands near the cuttingarea.
• Place your hands no closer than 100mm from theblade.
• Hold the workpiece tightly to the table and the fence when cutting.
Keep your hands in position until the switch has been released and
the blade has completelystopped.
• Always make dry runs (without power) before finish cuts so that
you can check the path of theblade.
• Do not cross yourhands.
• Keep both feet firmly on the floor and maintain properbalance.
• As you move the saw arm left and right, follow it and stand slightly
to the side of the sawblade.
Basic Saw Cuts
Vertical Straight Cross-Cut (Fig.A,N)
NOTE: Use 216mm saw blades with 30mm arbor holes to obtain the
desired cuttingcapacities.
1. Slacken the mitre latch
12
and subsequently lift itup.
2. Engage the mitre latch
12
at the 0° position and fasten the mitrelatch.
3. Place the wood to be cut against the fence
15
.
4. Take hold of the operating handle and press the guard lock up release
lever
2
to release the guard. Extend the head of the saw all the wayout.
5. Flip the lock off switch
28
and press the on/off trigger switch
1
to start
themotor.
6. Depress the head to allow the blade to cut through the timber and
enter the plastic kerfplate
10
.
7. When the head is fully depressed, slowly push it back across to
complete thecut.
8. After completing the cut, release the switch and wait for the saw blade
to come to a complete standstill before returning the head to its upper
restposition.

WARNING:
• The lower blade guard is designed to close quickly when the
lever
2
is released. If it does not close within 1 second, have the
saw serviced by an authorized
DeWALT
repairagent.
Performing a Sliding Cut (Fig.A,B,O)
1. Turn the rail lock knob
17
toloosen.
2. Push down the saw head
23
, pull out the lock down pin
21
and let
the saw head rise to it’s highestposition.
3. Place the wood to be cut against the sliding fence
15
and secure it
with the material clamp
16
.
4. Lower the saw head then pull it to the end of itstravel.
5. Press the guard lock-up release lever
2
to release the guard. Flip
the lock off switch
28
and press the on/off trigger switch
1
to start
themotor.
6. Totally depress the head to allow the blade to cut through the timber
and push the head back to complete thecut.
7. After completing the cut, release the switch and wait for the saw blade
to come to a complete standstill before returning the head to its upper
restposition.

WARNING: Remember to lock the saw head in the rear position when
the sliding cuts arefinished.
Vertical Mitre Cross-Cut (Fig.A,P)
1. Squeeze the mitre latch
12
. Move the arm left or right to the
requiredangle.
2. The mitre latch will automatically locate at 0°, 15°, 22.5°, 31.62°, 45° and
50° both left and right. If any intermediate angle is required hold the
head firmly and lock by fastening the mitrelatch.
3. Always ensure that the mitre latch is locked tightly beforecutting.
4. Proceed as for a vertical straight cross-cut.

WARNING: When mitring the end of a piece of wood
with a small off-cut, position the wood to ensure that the off-cut is to
the side of the blade with the greater angle to the fence, i.e.:
• left mitre, off-cut to the right
• right mitre, off-cut to the left
Bevel Cross-Cuts (Fig.L, Q)
Bevel angles can be set from 0° to 48° to the left. Bevels up to 45° can be cut
with the mitre arm set between zero and a maximum of 45° mitre position
right orleft.
1. Loosen the bevel clamp handle
18
by pulling it outward then down
and set the bevel asdesired.
2. Set the override lever
29
ifrequired.
3. Hold the head firmly and do not allow it tofall.
4. Tighten the bevel clamp handle
18
firmly.
5. Proceed as for a vertical straight cross-cut.
Quality of Cut
The smoothness of any cut depends on a number of variables, i.e. the
material being cut. When smoothest cuts are desired for moulding andother
precision work, a sharp (60-tooth carbide) blade and a slower, even cutting
rate will produce the desiredresults.
