Compound Mitre (Fig.S, T)
This cut is a combination of a mitre and a bevel cut. This is the type of cut
used to make frames or boxes with slanting sides like the one shown in
FiguresS and T.

WARNING: If the cutting angle varies from cut to cut, check that
the bevel clamp handle and the mitre clamping knob are securely
tightened. These must be tightened after making any changes in bevel
ormitre.
• The chart shown below will assist you in selecting the proper bevel and
mitre settings for common compound mitrecuts.
• To use the chart, select the desired angle “A” (Fig.T) of your project
and locate that angle on the appropriate arc in the chart. From that
point follow the chart straight down to find the correct bevel angle and
straight across to find the correct mitreangle.
Set this miter angle on saw
Angle of side of box (angle ”A”)
Set this bevel angle on saw
1. Set your saw to the prescribed angles and make a few trialcuts.
2. Practice fitting the cut piecestogether.
Example: To make a four-sided box with 25° exterior angles (angle “A”)
(Fig.T), use the upper right arc. Find 25° on the arc scale. Follow the
horizontal intersecting line to either side to get the mitre angle setting
on the saw (23°). Likewise follow the vertical intersecting line to the top
or bottom to get the bevel angle setting on the saw (40°). Always try
cuts on a few scrap pieces of wood to verify the settings on thesaw.

WARNING: Never exceed the compound mitre limits of 45° bevel with
45° left or rightmitre.
Dust Extraction (Fig.A, U)

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
30
that allows connection to
either a dust bag (33mm nozzles) or direct attachment to the DeWALT
AirLock(DWV9000-XJ)
45
.
Observe the relevant regulations in your country for the materials to
beworked.
To Attach the Dust Bag
1. Fit a dust bag to the dust port
30
.
To Empty the Dust Bag
1. Remove dust bag 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.
External Dust Extraction
When vacuuming dry dust that is especially detrimental to health or
carcinogenic, use a special dust Class M vacuumcleaner.
Connecting to an AirLock Compatable Dust Extractor (Fig.U)
The dust port
30
on your mitre saw is compatable with the DeWALT
AirLock connection system. The AirLock allows for a fast, secure connection
between the dust extractor hose and the mitresaw.
1. Ensure the collar on the AirLock connector
45
is in the unlock position.
Align notches on collar and AirLock connector as shown for unlock and
lockpositions.
2. Push the AirLock connector onto the dust port
30
.
3. Rotate the collar to the lockedposition.
NOTE: The ball bearings inside collar lock into slot and secure
the connection.The mitre saw is now securely connected to the
dustextractor.
MAINTENANCE
Your DeWALT power tool has been designed to operate over a long period
of time with a minimum of maintenance. Continuous satisfactory operation
depends upon proper tool care and regularcleaning.

WARNING: To reduce the risk of serious personal injury, turn
machine off and disconnect battery pack before making any
adjustments or removing/installing attachments or accessories.
An accidental start-up can causeinjury.

WARNING: If the saw blade is worn replace it with a new sharpblade.
Lubrication
Your power tool requires no additionallubrication.
Cleaning
Before use, carefully check the upper blade guard, movable lower blade
guard as well as the dust extraction tube to determine that it will operate
properly. Ensure that chips, dust or workpiece particle cannot lead to
blockage of one of thefunctions.
In case of workpiece fragments jammed between saw blade and guards
disconnect the machine from the power supply and follow the instructions
given in section Changing or Installing a New Saw Blade. Remove the
jammed parts and reassembling the sawblade.

WARNING: Blow dirt and dust out of the main housing with dry air
as often as dirt is seen collecting in and around the air vents. Wear
