DeWalt DW717XPS Original Instructions Manual page 37

• 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" (fi g. Q2) of your project and locate that
angle on the appropriate arc in the chart. From that point follow the
chart straight down to fi nd the correct bevel angle and straight across
to fi nd the correct mitre angle.
• Set your saw to the prescribed angles and make a few trial cuts.
• Practice fi tting the cut pieces together.
• Example: To make a 4 sided box with 25° exterior angles (angle "A")
(fi g. Q2), 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.

Cutting base mouldings
The cutting of base moulding is performed at a 45° bevel angle.
• Always make a dry run without power before making any cuts.
• All cuts are made with the back of the moulding laying fl at on the saw.
Inside corner
- Left side
• Position the moulding with top of the moulding against the fence.
• Save the left side of the cut.
- Right side
• Position the moulding with the bottom of the moulding against the
fence.
• Save the left side of the cut.
Outside corner
- Left side
• Position the moulding with the bottom of the moulding against the
fence.
• Save the right side of the cut.
- Right side
• Position the moulding with top of the moulding against the fence.
• Save the right side of the cut.
Cutting crown mouldings
The cutting of crown moulding is performed in a compound mitre. In
order to achieve extreme accuracy, your saw has pre-set angle positions
at 31.62° mitre and 33.85° bevel. These settings are for standard crown
mouldings with 52° angles at the top and 38° angles at the bottom.
SQUARE BOX
• Make test cuts using scrap material before doing the fi nal cuts.
• All cuts are made in a left bevel and with the back of the moulding
against the base.
Inside corner
- Left side
• Top of the moulding against the fence.
• Mitre right.
• Save the left side of the cut.
- Right side
• Bottom of the moulding against the fence.
• Mitre left.
• Save the left side of the cut.
Outside corner
- Left side
• Bottom of the moulding against the fence.
• Mitre left.
• Save the right side of the cut.
- Right side
• Top of the moulding against the fence.
• Mitre right.
• Save the right side of the cut.
Grooving (fi g. R)
Your saw is equipped with a grooving stop (17) and thumbscrew (59) to
allow for groove cutting.
• Flip the grooving stop (17) towards the front of the saw.
• Adjust the thumbscrew (59) to set the depth of the groove cut. It might
be necessary to release the lock nut (60) fi rst.
• Place a piece of scrap material of approx. 5 cm between fence and
workpiece in order to perform a straight groove cut.
Special Set-up for Wide Crosscuts (fi g. A1, S1, S2)
Your saw can cut very wide (up to 391 mm) workpieces when a special
set up is used. To set the saw up for these workpieces, follow these steps:
• Remove both left and right sliding fences from the saw and set aside.
To remove them, unscrew the fence knobs several turns and slide each
fence outward. Adjust and lock the miter control so that it is at
0 degrees miter.
• Remove backfence screws (64) from right rear foot and install them into
the right hand fence (62) screw holes.
WARNING: Do not cut material using the special setup without
properly installing the backfence screws (64), otherwise the
material will not be supported properly and may cause loss of
control and possible injury.
• Make a platform using a piece of 38 mm thick particleboard or similar
fl at strong 38 mm thick wood to the dimensions: 368 x 660 mm. The
platform must be fl at otherwise the material could move during cutting
and cause injury.
• Mount the 368 x 660 mm platform to the saw using four 76.2 mm long
wood screws (64) through the holes in the base fence. Four screws
must be used to properly secure the material. When the special set up
is used, the platform will be cut into two pieces. Ensure the screws are
tightened properly otherwise material could loosen and cause injury.
Ensure the platform is fi rmly fl at on the table, against the fence, and
centered evenly from left to right.
WARNING: Ensure the saw is mounted fi rmly to a stable fl at
surface. Failure to do so could cause the saw to be unstable
and fall causing personal injury.
• Place the workpiece to be cut on top of the platform mounted to the
table. Ensure the workpiece is fi rmly against the backfence.
