DeWalt DWS771 - Cutting Large Material; Quality of Cut; To Install Clamp

ENGLISH
10
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.
Support for Short and Long Pieces (Fig. C, D)
Cutting Short Material
It is advisable to use the length stop
41
for short workpieces both for batch sawing and
for short individual workpieces of different lengths. The length stop can only be used in
conjunction with a pair of optional guide rails
35
.
Cutting Large Material

WARNING: To reduce the risk of injury, always support longworkpieces.
Figure C shows the ideal configuration for sawing long workpieces when the saw is used free-
standing (all items available as an option).
These items (except the legstand and the material clamp) are required both on the infeed and
the outfeedside:
- Legstand
40
(supplied with mounting instructions).
- Guide rails (500 or 1,000mm)
35
.
- Stands
39
to support the guide rails. Do not use the stands to support the machine!
The height of the stands isadjustable.
- Material support plates
36
.
- Table end plate
34
for supporting the rails (also when working on an existing bench).
- Material clamp
17
.
- Swivelling stop
38
.
1. Place your saw on the legstand and fit the guiderails.
2. Firmly screw the material support plates
36
to the guide rails
35
.
3. The material clamp
17
now functions as a lengthstop.
4. Install the table end plates
34
.
5. Install the swivelling stop
38
to the rearrail.
6. Use the swivelling stop
38
to adjust the length of medium and long workpieces. It can be
adjusted sideways or swung out of the way when not inuse.
Dust Extraction (Fig. A, K)

WARNING: Whenever possible, connect a dust extraction device designed in accordance
with the relevant regulations regarding dustemission.
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running.
NOTE: The DWV9000 twist-lock quick connector
43
is recommended as an optional
accessory to connect to the dust extractiondevice.
Observe the relevant regulations in your country for the materials to be worked.
The vacuum cleaner must be suitable for the material being worked.
When vacuuming dry dust that is especially detrimental to health or carcinogenic, use a
special vacuum cleaner.
Transporting (Fig. A, B)

WARNING: In order to conveniently carry the mitre saw, the base is provided with two
hand indentations
32
. Never use guards to lift or transport the mitresaw.
1. To transport the saw, set the bevel and mitre positions to 0°.
2. Press the lower guard lock up release lever
2
(Fig.A).
3. Press the head down and press the lock down button
23
(Fig.B).
4. Bring the saw blade to rest position and press the traverse lock
18
.
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 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.

WARNING: If the saw blade is worn replace it with a new sharpblade.
Lubrication
Your power tool requires no additionallubrication.

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. P, U)
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
20
and set the bevel asdesired.
2. Set the override button
31
ifrequired.
3. Hold the head firmly and do not allow it tofall.
4. Tighten the bevel clamp handle
20
firmly.
5. Proceed as for a vertical straight cross-cut.
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. C, X)

WARNING: Always use a materialclamp.
For best results use the material clamp
17
made for use with yoursaw.
To Install clamp
1. Insert it into the hole behind the fence. The clamp
17
should be facing toward the back
of the mitre saw. Ensure the groove on the clamp rod is fully inserted into the base of the
mitre saw. If the groove is visible, the clamp will not besecure.
2. Rotate the clamp 180º toward the front of the mitresaw.
3. Loosen the knob to adjust the clamp up or down, then use the fine adjust knob to firmly
clamp theworkpiece.
NOTE: Place the clamp on the right side of the base when beveling. ALWAYS MAKE DRY RUNS
(UNPOWERED) BEFORE FINISH CUTS TO CHECK THE PATH OF THE BLADE. ENSURE THE CLAMP
DOES NOT INTERFERE WITH THE ACTION OF THE SAW ORGUARDS.
Compound Mitre (Fig. W)
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W.

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.W) 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.

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.W), 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°).
