OPERATION
Instructions for Use

WARNING: Always observe the safety instructions and
applicableregulations.

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.
Guard Actuation and Visibility (Fig. Y)
The lower guard
1
on your saw has been designed to automatically
uncover the blade when the arm is brought down and to cover the blade
when the arm israised.
The guard can be raised by hand when installing or removing saw blades
or for inspection of the saw. NEVER RAISE THE lower GUARD MANUALLY
UN LESS THE BLADE ISSTOPPED.
Rail Guide Adjustment (Fig. A1)
Regularly check the rails
9
for play orclearance.
The left rail can be adjusted with the set screw
7
. To reduce clearance,
use a 4 mm hex wrench and rotate the set screw clockwise gradually while
sliding the saw head back andforth.
Mitre Lock Adjustment (Fig. A1, N)
The mitre lock rod
60
should be adjusted if the table of the saw can be
moved when the mitre lock handle is locked (down).
1. Put the mitre lock handle
21
in the unlocked (up)position.
2. Using a slotted screwdriver, tighten the mitre lock rod by turning it
clockwise as shown in FigureN. Turn the lock rod until it is snug, then
turn counterclockwise oneturn.
3. Re-lock the mitre lock to a non-detented measurement on the mitre
scale – for example, 34° – and make sure the table will notrotate.
Prior to Operation (Fig. A1, A2)
• Install the appropriate saw blade. Do not use excessively worn blades.
The maximum rotation speed of the tool must not exceed that of the
saw blade. Do not use any abrasiveblades.
• Check protective belt cover
37
for damage and proper functioning of
lower guard
1
• Install the table extensions to both sides of the saw's base. Refer to
Assembling the Base Extensionssection.
• Do not attempt to cut excessively smallpieces.
• Allow the blade to cut freely. Do notforce.
• Allow the motor to reach full speed beforecutting.
• Make sure all locking knobs and clamp handles aretight.
• Secure theworkpiece.
• 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!
• Make sure to use the kerf plate. Do not operate the machine if the kerf
slot is wider than 12mm.
• Connect saw to an external dustextractor.
Proper Body and Hand Position (Fig. O1, O2)

WARNING: To reduce the risk of serious personal injury, ALWAYS use
proper hand position as shown in FigureO1.

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O2.
• 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
25
to the left, then depress the
trigger switch
24
. 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
26
is provided
in the trigger for insertion of a padlock to lock the switchoff.
Your saw is equipped with an automatic electric blade brake, but the saw
blade should stop within 4 seconds of triggerrelease.
Always be sure the blade has stopped before removing it from thekerf.
Dust Extraction (Fig.A2, D, AA)

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.

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.

CAUTION: Never operate this saw unless the dust bag or
DeWALT dust extractor is in place. Wood dust may create a
breathinghazard.

CAUTION: Check and clean the dust bag each time afterusing.

WARNING: When sawing aluminium, remove the dust bag, or
disconnect the dust extractor to avoid the risk offire.
Your mitre saw has a built-in dust port
36
that allows connection to either
the dust bag
40
, 33mm nozzles or direct attachment to the DeWALT
AirLock(DWV9000-XJ).
Observe the relevant regulations in your country for the materials to
beworked.
To Attach the Dust Bag (Fig. D)
1. Fit the dust bag
40
to the dust port
36
as shown in FigureD.
To Empty the Dust Bag (Fig. D)
1. Remove dust bag
40
from the saw and gently shake or tap the dust
bag toempty.
2. Reattach the dust bag back onto the dust port
36
.
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.
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.
