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.
The attention of UK users is drawn to the “woodworking machines regulations 1974” and any
subsequentamendments.
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)
A hole
30
is provided in the on/off switch
1
for insertion of a padlock to lock thetool.
1. To run the tool, press the on/off switch
1
.
2. To stop the tool, release theswitch.
Use of XPS™ LED Worklight System (Fig. A, V)
NOTE: The mitre saw must be connected to a powersource.
The XPS™ LED Worklight System is operated with an push button switch, fitted on the handle
under the black plastic lever. The XPS™ LED Worklight System is independent of the mitre
saw’s triggerswitch.
To cut through an existing pencil line on a piece ofwood:
1. Push the black plastic lever, then pull down on the operating handle
3
to bring the saw
blade
8
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.
Speed Control Dial (DWS771 only)
The speed control dial
29
can be used for advance setting of the required range ofspeed.
Turn the speed control dial
29
to the desired range, which is indicated by a number (1–5).
• Use high speeds for sawing soft materials such aswood.
• Use low speeds for sawinghardwood.
Body and Hand Position
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 150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, S)
NOTE: Use 216mm saw blades with 30mm arbor holes to obtain the desired
cuttingcapacities.
1. Slacken the mitre latch
13
and subsequently lift itup.
2. Engage the mitre latch
13
at the 0° position and fasten the mitrelatch.
3. Place the wood to be cut against the fence
16
.
4. Take hold of the carrying handle
3
and press the guard lock up release lever
2
to release
the guard. Press the trigger switch
1
to start the motor. It is recommended to start the cut
near thefence.
5. Depress the head to allow the blade to cut through the timber and enter the plastic
kerfplate
11
.
6. When the head is fully depressed, slowly pull it across 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:
• For some types of plastic profiles, it is advisable to follow the sequence in reverseorder.
• 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.
Vertical mitre cross-cut (Fig. A, T)
1. Squeeze the mitre latch
13
. 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 lock lever is locked tightly beforecutting.
4. Proceed as for a vertical straight cross-cut.
2. Press the saw head fully to the rear position and measure the height from the rotating
table
14
to the bottom of the outer flange
5
(Fig.J).
3. Turn the saw head traverse lock
18
(Fig.B).
4. Keeping the saw head fully depressed, pull the head to the end of itstravel.
5. Measure the height indicated in figureK again. Both values should beidentical.
6. If adjustment is required, proceed as follows (Fig.L):
a. Loosen the locknut
46
in the bracket
47
under the upper dust extraction nozzle
37
and adjust the screw
48
as required, proceeding in smallsteps.
b. Tighten the locknut
46
.

WARNING: Always check that the blade does not touch the table at the rear of the slot or
at the front of the rotating arm at 90° vertical and 45° bevel positions. Do not switch on
before having checked this!
Adjusting the Fence (Fig. M)
Turn the sliding fence lock knob
9
anti-clockwise to loosen. Move the sliding fence
16
to a
position that avoids the blade cuts it,then tighten the fence lock knob by turningclockwise.
Checking and Adjusting the Blade to the Fence (Fig. B, N, O, Q)
1. Slacken the mitre latch
13
.
2. Place your thumb on the mitre arm
12
and squeeze the mitre latch
13
to release the
rotating table/mitre arm
14
.
3. Swing the mitre arm until the latch locates it at the 0° mitreposition.
4. Pull down the head and lock it in this position using the lock down button
23
.
5. Check that the two 0° markings
49
on the mitre scale
15
are justvisible.
6. Place a square
50
against the left side of the fence
16
and blade
8
.

WARNING: Do not touch the tips of the blade teeth with thesquare.
7. If adjustment is required, proceed asfollows:
a. Loosen the screws
51
and move the scale/mitre arm assembly left or right until the
blade is at 90° to the fence as measured with the square (Fig.N).
b. Retighten the screws
51
.
Checking and Adjusting the Blade to the Table (Fig. P–R)
1. Loosen the bevel clamp handle
20
(Fig.P).
2. Press the saw head to the right to ensure it is fully vertical and tighten the bevel
clamphandle.

a. Loosen the bevel clamp handle
20
and turn the vertical position adjustment stop
screw
52
in or out until the blade is at 90° to the table as measured with thesquare.
b. If the bevel pointer
53
does not indicate zero on the bevel scale
21
, loosen the
screws
54
that secure the scale and move the scale asnecessary.
Checking and Adjusting the Bevel Angle
(Fig. A, P, R)
The bevel override allows the max. bevel angle to be set at 45° or 48° asrequired.
• Left = 45°
• Right = 48°
1. Make sure the override knob
55
is located in the leftposition.
2. Loosen the bevel clamp handle
20
and move the saw head to theleft.
3. This is the 45° bevelposition.
4. If adjustment is required, turn the stopscrew
56
in or out as necessary until the
pointer
53
indicates 45°.

WARNING: The guide grooves can become clogged with sawdust. Use a stick or some
low pressure air to clear the guidegrooves.
Prior to Operation

WARNING:
• Install the appropriate saw blade. Do not use excessively worn blades. The maximum
rotation speed of the tool must not exceed that of thesawblade.
• 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 sameguide-lines apply to the other
materials. Do not cut ferrous (iron and steel) materials or masonry with this saw! Do
not use any abrasive discs!
• Make sure to use the kerf plate. Do not operate the machine if the kerf slot is wider
than 10mm.
• Placing the workpiece on a piece of wood will increase the capacities to 300mm.
