• Use personal protective equipment and connect the saw to an external
dust extractor.
• Although this saw will cut wood and many nonferrous materials, these
operating instructions refer to the cutting of wood only. The same
guidelines apply to the other materials. Do not cut ferrous (iron and
steel) materials, fibre cement or masonry with this saw!
• Do not attempt to cut excessively small pieces.
• Secure the workpiece.
• Allow the blade to cut freely. Do not force.
• Allow the motor to reach full speed before cutting.
OPERATION
Instructions for Use

WARNING: Always observe the safety instructions and
applicable regulations.

WARNING: To reduce the risk of injury, turn unit off and
disconnect machine from power source before installing and
removing accessories, before adjusting or changing set-ups
or when making repairs. Be sure the trigger switch is in the OFF
position. An accidental start-up can cause injury.
Refer to saw Blades under Optional Accessories to select the blade that
best fits your needs.
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 vibration, make sure the environment temperature is
not too cold, the machine and accessories are well maintained and the
workpiece size is suitable for this machine.
Be sure the cord will not interfere with your work.
Proper Body and Hand Position (Fig. N1, N2)

WARNING: To reduce the risk of serious personal injury, ALWAYS use
proper hand position as shown in Figure N1.

WARNING: To reduce the risk of serious personal injury, ALWAYS hold
securely in anticipation of a sudden reaction.
• Never place hands near cutting area. Place hands no closer than
100 mm from the blade.
• Hold the workpiece tightly to the table and the fence when cutting.
Keep hands in position until the trigger has been released and the blade
has completely stopped.
• ALWAYS MAKE DRY RUNS (UNPOWERED) BEFORE FINISH CUTS SO THAT
YOU CAN CHECK THE PATH OF THE BLADE. DO NOT CROSS HANDS, AS
SHOWN IN FIGURE N2.
• Keep both feet firmly on the floor and maintain proper balance. As you
move the mitre arm left and right, follow it and stand slightly to the side
of the saw blade.
• Sight through the guard louvers when following a pencil line.
Trigger Switch (Fig. A2)
To turn the saw on, push the lock-off lever
trigger switch 22 . The saw will run while the switch is depressed. Allow the
blade to spin up to full operating speed before making the cut. To turn the
saw off, release the switch. Allow the blade to stop before raising the saw
head. There is no provision for locking the switch on. A hole
in the trigger for insertion of a padlock to lock the switch off.
Your saw is not equipped with an automatic electric blade brake, but the
saw blade should stop within 10 seconds of trigger release. This is not
adjustable. If the stop time repeatedly exceeds 10 seconds, have the tool
serviced by an authorised D WALT service centre.

Always be sure the blade has stopped before removing it from the kerf.

Setting the Variable Speed (Fig. A2)
The speed control dial can be used for advance setting of the required
35
range of speed.
• Turn the speed control dial 35
by a number.
• Use high speeds for sawing soft materials such as wood.
Use low speeds for sawing metal.
Dust Extraction (Fig. A2, C)

WARNING: Certain dust, such as oak or beech dust, is
considered carcinogenic, especially in connection with wood-
treatment additives.
• Always use dust extraction.
• Provide for good ventilation of the work space.
• It is recommended to wear an appropriate respirator.
Your saw has a built-in dust port
33
shop vacuum system to be connected.
To Attach the Dust Bag
1. Fit the dust bag 38 to the dust port
To Empty the Dust Bag
1. Remove dust bag 38 from the saw and gently shake or tap the dust
bag to empty.
2. Reattach the dust bag back onto the dust port
You may notice that all the dust will not come free from the bag. This will
not affect cutting performance but will reduce the saw's dust collection
efficiency. To restore your saw's dust collection efficiency, depress the spring
inside the dust bag when you are emptying it and tap it on the side of the
trash can or dust receptacle.

CAUTION: Never operate this saw unless the dust bag or
D WALT dust extractor is in place. Wood dust may create a
e
breathing hazard.
Use of XPS LED Worklight System (Fig. A1, A2)
nOTE: The mitre saw must be connected to a power source.
The XPS LED Worklight System is equipped with an on/off switch
XPS LED Worklight System is independent of the mitre saw's trigger switch.
The light does not need to be on in order to operate the saw.
To cut through an existing pencil line on a piece of wood:
1. Turn on the XPS system, then pull down on the operating handle
bring the saw blade 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.
Through-Cutting Operations (Fig. A1, A2, O, P)
If the slide feature is not used, ensure the saw head is pushed back as far
as possible and the rail lock knob 4
from sliding along its rails as the workpiece is engaged.
Cutting of multiple pieces is not recommended but can be done safely by
ensuring that each piece is held firmly against the table and fence.
Straight Vertical Crosscut
1. Set and lock the mitre arm at zero, and hold the wood firmly on the
table 15 and against the fence
2. With the rail lock knob 4 tightened, turn on the saw by squeezing the
trigger switch 22 .
3. When the saw comes up to speed, lower the arm smoothly and slowly
to cut through the wood. Let the blade come to a full stop before
raising arm.
Sliding Crosscut (Fig. O)
When cutting anything larger than a 51 x 150 mm (51 x 105 mm at
45° mitre) workpiece, use an out-down-back motion with the rail lock
knob loosened.
