The vibration emission level given in this information sheet has been
measured in accordance with a standardised test given in EN 61029
and may be used to compare one tool with another. It may be used for
a preliminary assessment of exposure.
WARNING: The declared vibration emission level
represents the main applications of the tool. However if
the tool is used for different applications, with different
accessories or poorly maintained, the vibration emission
may differ. This may significantly increase the exposure level
over the total working period.
An estimation of the level of exposure to vibration should
also take into account the times when the tool is switched
off or when it is running but not actually doing the job. This
may significantly reduce the exposure level over the total
working period.
Identify additional safety measures to protect the operator
from the effects of vibration such as: maintain the tool and
the accessories, keep the hands warm, organisation of
work patterns.

General Safety Rules
1.Keep work area clear.
Cluttered areas and benches invite injuries.
2.Consider work area environment.
Do not expose the tool to rain. Do not use the tool in damp or
wet conditions. Keep the work area well lit (250 - 300 Lux). Do
not use the tool where there is a risk of causing fire or explosion,
e.g., in the presence of flammable liquids and gases.
3.Guard against electric shock.
Avoid body contact with earthed surfaces (e.g., pipes, radiators,
cookers and refrigerators). When using the tool under extreme
conditions (e.g., high humidity, when metal swarf is being
produced, etc.), electric safety can be improved by inserting an
isolating transformer or a (FI) earth-leakage circuit-breaker.
4.Keep other persons away.
Do not let persons, especially children, not involved in the work,
touch the tool or the extension cord and keep them away from
the work area.
5.Store idle tools.
When not in use, tools must be stored in a dry place and locked
up securely, out of reach of children.
6.Do not force the tool.
It will do the job better and safer at the rate to which it was
intended.
7.Use the right tool.
Do not force small tools to do the job of a heavy duty tool. Do
not use tools for purposes not intended; for example do not
use circular saws to cut tree limbs or logs.
8.Dress properly.
Do not wear loose clothing or jewellery, as these can be caught in
moving parts. Non-skid footwear is recommended when working
outdoors. Wear protective hair covering to contain long hair.
9.Use protective equipment.
Always use safety glasses. Use a face or dust mask if working
operations create dust or flying particles. If these particles might
be considerably hot, also wear a heat-resistant apron. Wear ear
protection at all times. Wear a safety helmet at all times.
10. Connect dust extraction equipment.
If devices are provided for the connection of dust extraction and
collecting equipment, ensure these are connected and properly
used.
11.Do not abuse the cord.
Never yank the cord to disconnect it from the socket. Keep
the cord away from heat, oil and sharp edges. Never carry the
tool by its cord.
12.Secure work.
Where possible use clamps or a vice to hold the work. It is safer
than using your hand and it frees both hands to operate the tool.
13.Do not overreach.
Keep proper footing and balance at all times.
14.Maintain tools with care.
Keep cutting tools sharp and clean for better and safer
performance. Follow instructions for lubricating and changing
accessories. Inspect tools periodically and if damaged have
them repaired by an authorized service facility. Keep handles
and switches dry, clean and free from oil and grease.
15.Disconnect tools.
When not in use, before servicing and when changing accessories
such as blades, bits and cutters, disconnect tools from the power
supply.
17.Avoid unintentional starting.
Do not carry the tool with a finger on the switch. Be sure that the
tool is in the “off” position before plugging in.
18.Use outdoor extension leads.
Before use, inspect the extension cable and replace if damaged.
When the tool is used outdoors, use only extension cords intended
for outdoor use and marked accordingly.
19.Stay alert.
Watch what you are doing. Use common sense. Do not operate the
tool when you are tired or under the influence of drugs or alcohol.
20.Check for damaged parts.
Before use, carefully check the tool and mains cable to determine
that it will operate properly and perform its intended function.
Check for alignment of moving parts, binding of moving parts,
breakage of parts, mounting and any other conditions that may
affect its operation. A guard or other part that is damaged should
be properly repaired or replaced by an authorized service centre
unless otherwise indicated in this instruction manual. Have
defective switches replaced by an authorized service centre.
Do not use the tool if the switch does not turn it on and off.
Never attempt any repairs yourself.
Warning! The use of any accessory or attachment or
performance of any operation with this tool other than
those recommended in this instruction manual may
present a risk of personal injury.
21.Have your tool repaired by a qualified person.
This electric tool complies relevant safety rules. Repairs should
only be carried out by qualified persons using original spare parts;
otherwise this may result in considerable danger to the user.

Bench Mounting (fig. 2) 
Intended Use
1.Holes (v) are provided in all four feet to facilitate bench mounting.
Two different sized holes are provided to accommodate different
sizes of bolts. Use either hole; it is not necessary to use both.
Bolts with a diameter of 8 mm and 80 mm in length is suggested.
Always mount your saw firmly to prevent movement. To enhance
the portability, the tool can be mounted to a piece of 12.5 mm or
thicker plywood which can then be clamped to your work support
or moved to other job sites and reclamped.
Your DeWALT Cross-Cut Mitre Saw has been designed for professional
cutting wood, wood products and plastics. It performs the sawing
operations of cross-cutting, bevelling and mitring easily, accurately and
safely.
This unit is designed for use with a nominal blade diameter 216 mm
carbide tip blade.
Do not use under wet conditions or in presence of flammable liquids
or gases.
These miter saws are professional power tools.
Do not let children come into contact with the tool. Supervision is
required when inexperienced operators use this tool.
WARNING! Do not use the machine for purposes other
than intended.
Electrical Safety
The electric motor has been designed for one voltage only. Always
check that the power supply corresponds to the voltage on the rating
plate.
Your tool is double insulated in accordance with EN 61029;
therefore no earth wire is required.
2.When mounting your saw to a piece of plywood, make sure that
the mounting screws do not protrude from the bottom of the wood.
The plywood must sit flush on the work support. When clamping
the saw to any work surface, clamp only on the clamping bosses
where the mounting screw holes are located. Clamping at any
other point will interfere with the proper operation of the saw.
3.To prevent binding and inaccuracy, be sure the mounting surface is
not warped or otherwise uneven. If the saw rocks on the surface,
place a thin piece of material under one saw foot until the saw is
firm on the mounting surface.

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
temperature is not too cold, machine and accessory are well maintained
and the workpiece is suitable for this machine.
Switching On and Off (fig. 1)
A hole (dd) is provided in the on/off switch (a) for insertion of a padlock
to lock the tool.
• 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 (b) 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. 1, 21)
1.Squeeze the mitre latch (m). 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.
1.To run the tool, press the on/off switch (a).
2.To stop the tool, release the switch.
Speed control Dial (DW771 only)
The speed control dial (cc) can be used for advance setting of the
required range of speed.
Turn the speed control dial (cc) 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.
Warning:
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. 18, 22)
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 (t) and set the bevel as desired.
2.Set the override button (ee) if required.
3.Hold the head firmly and do not allow it to fall.
Body and Hand Position
4.Tighten the bevel clamp handle (t) firmly.
Proper positioning of your body and hands when operating the mitre
saw will make cutting easier, more accurate and safer.
5.Proceed as for a vertical straight cross-cut.
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. 1, 20)
NOTE: Use 216 mm saw blades with 30 mm arbor holes to
obtain the desired cutting capacities.
1.Slacken the mitre latch (m) and subsequently lift it up.
2.Engage the mitre latch (m) at the 0° position and fasten the mitre
latch.
3.Place the wood to be cut against the fence (p).
4.Take hold of the carrying handle (c) and press the guard lock up
release lever (b) to release the guard. Press the trigger switch (a) 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 (k).
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.
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.
WARNING: Ensure that the material does not creep while
cutting; clamp it securely in place. Always let the blade
come to a full stop before raising the arm. If small fibres of
wood still split out at the rear of the workpiece, stick a piece
of masking tape on the wood where the cut will be made.
Saw through the tape and carefully remove tape when
finished.
Clamping the Workpiece (fig. 3, 25–27)
1.Whenever possible, clamp the wood to the saw.
2.For best results use the material clamp (kk) made for use with your
saw. Clamp the workpiece to the fence whenever possible. You
can clamp to either side of the saw blade; remember to position
your clamp against a solid, flat surface of fence.
WARNING: Always use a material clamp when cutting
non-ferrous metals.
Compound Mitre (fig. 23, 24)
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 figure 23.
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. 24) 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 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. 24), 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.
Connect a dust collection device designed in accordance with the
relevant regulations. The air velocity of externally connected systems
shall be 20m/s +/- 2 m/s. Velocity to be measured in the connection
tube at the point of connection, with the tool connected but not
