Quality Of Cut - DeWalt DWS771 Original Instructions Manual

1. Loosen the bevel clamp handle
and set the bevel as desired.
2. Set the override lever 29 if required.
3. Hold the head firmly and do not allow it to fall.
4. Tighten the bevel clamp handle
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. R)

WARNING: A workpiece that is clamped, balanced and secure
before a cut may become unbalanced after a cut is completed. An
unbalanced load may tip the saw or anything the saw is attached to,
such as a table or workbench. When making a cut that may become
unbalanced, properly support the workpiece and ensure the saw is
firmly bolted to a stable surface. Personal injury may occur.

WARNING: The clamp foot must remain clamped above the base of
the saw whenever the clamp is used. Always clamp the workpiece to
the base of the saw – not to any other part of the work area. Ensure
the clamp foot is not clamped on the edge of the base of the saw.

CAUTION: Always use a work clamp to maintain control and reduce
the risk of personal injury and workpiece damage.
For best results use the material clamp
To Install Clamp
1. Insert it into the hole behind the fence. The clamp
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. 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
Figure S.

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 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 tool from power source 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
D WALT dust extractor is in place. Wood dust may create a
e
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
either a dust bag (33 mm nozzles) or direct attachment to the D
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 31
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
