Prior To Operation - DeWalt DW743N Original Instructions Manual

WARNING: Always make a trial cut in a piece of waste
wood, to check for accuracy.
Adjusting the Fence (fi g. J1, J2)
The moveable part of the left side of the fence can be adjusted to
provide maximum support of the workpiece near the blade, while
allowing the saw to bevel to a full 45° left. The sliding distance is limited
by stops in both directions. To adjust the fence (7):
• Lift the lever (72) to release the fence (7).
• Slide the fence to the left.
• Make a dry run with the saw switched off and check for clearance.
Adjust the fence to be as close to the blade as practical to provide
maximum workpiece support, without interfering with the up and
down movement of the arm.
• Push the lever (72) down to secure the fence in place.
Checking and Adjusting the Bevel Angle
(fi g. J1, K1, K2)
• Slide the side fence to the left as far as it will go (fig. J1).
• Loosen the bevel clamp handle (22) and move the saw head to the
left. This is the 45° bevel position.
• If adjustment is required, proceed as follows:
• Turn the stopscrew (73) in or out as necessary until the pointer (74)
indicates 45°.
ASSEMBLY FOR BENCH SAW MODE
Changing from Mitre Saw to Bench saw Mode
(fi g. A1–A3, E2, L1, L2)
• Put the blade into 0° cross-cut position with the rotating table
location plunger (8) correctly located and the rotating table clamp
(3) secured (fig. A1).
• Slacken the riving knife clamp bolt (75) just enough to allow the
riving knife to enter the mounting slot (fig. L1).
• Take the riving knife (16) from its storage position against the saw
head (fig. A2).
• Depress the guard release lever (13) to release the blade guard
(12), then raise the blade guard as far as possible (fig. A1).
• Slide the riving knife bracket (76) fully into the mounting slot (77)
(fig. L1). Tighten the clamp bolt.
• Gently release the lower guard until it is held in place behind the
edge protruding from the inside of the riving knife.
• Remove the under-table guard.
• Pull down the saw head and swing the height adjuster (23) until its
U-shaped bracket (56) engages on the pin provided in the base
(fig. E2).
• Turn the wheel (55) of the adjuster to make the blade and riving
knife protrude from the bench saw table (24) (fig. A3) to provide
maximum cutting depth in bench saw mode.
WARNING: The blade should not foul the lower blade
guard.
• Pull the table release lever (2) to the left, lift the front edge of the
table and flip it back through 180° until the teeth of the table-
locking device (20) automatically engage the saw blade retention
lever to secure it in the bench saw mode (fig. L2).
WARNING: Be careful not to lose control over the
movement of the table.
Position of the Riving Knife (fi g. M)
• Fit the riving knife (16) as described above. Once fitted, the riving
knife does not require further adjustment.
Fitting the Upper Blade Guard (fi g. N)
The upper blade guard (25) is designed to be quickly and easily
attached, via a spring-loaded plunger to the hole in the riving knife
(16) once it has been positioned through the worktable for bench saw
mode.
Secure the upper blade guard (25) to the riving knife by pulling the knob
(76) to allow the plunger in the guard to engage.
WARNING: Never use your saw in bench saw mode
without the upper guard correctly fitted.
Mounting and Adjusting the Parallel Fence (fi g. O)
The dual height parallel fence (26) can be used in two positions (11 or
60 mm). The parallel fence can be mounted on either side of the blade.
TO MOUNT THE FENCE INTO THE APPROPRIATE POSITION,
PROCEED AS FOLLOWS:
• Loosen the knob (77).
• Slide the bracket on from the left or the right. The clamping plate
(78) engages behind the front edge of the table.
• Tighten the knob (77).
• Check that the fence is parallel to the blade.
• If adjustment is required, proceed as follows:
• Adjust the fence so that it is parallel to the blade by checking the
distance between the blade and the fence at the front and rear of
the blade. To do so, turn the adjustment screw in the fence support
in or out as necessary.
The default set-up of the fence is to the right-hand side of the blade.
TO PREPARE THE FENCE FOR USE TO THE LEFT-HAND SIDE OF THE BLADE,
PROCEED AS FOLLOWS:
• Loosen the knob (77).
• Pull out the bracket (79) and replace it in the other end.
• Fit the fence to the table.
• Tighten the knob (77).
WARNING: Use the 11 mm profile for ripping low
workpieces to allow access between the blade and the
fence for the push stick (17).
WARNING: The rear end of the fence should be level with
the front of the riving knife.
Changing from Bench saw to Mitre Saw Mode
(fi g. A3, D, E1, E2, L1)
• Remove the parallel fence (26) (fig. A3).
• Turn the wheel (55) of the height adjuster (23) to provide maximum
cutting depth in mitre saw mode (fig. E2).
• Proceed as described in the section "Turning the sawhead and
table over".
• Slacken the riving knife clamp bolt (75) and remove the riving knife
(16), while holding the blade guard (12) (fig. L1).
• Lower the blade guard.
• Place the riving knife in its storage position against the saw head.
• Replace the under-table guard (50) (fig. D).

Prior to Operation

• Install the appropriate saw blade. Do not use excessively worn
blades. The maximum rotation speed of the tool must not exceed
that of the saw 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.
