ENGLISH
When cutting crown molding laying flat, your saw is equipped to accurately 
and rapidly set a crown stop, left or right (refer to Instructions for Cutting 
Crown Molding Laying Flat and Using the Compound Features)
DWS780 (Fig. I)
The crown bevel pawl 
52
 can be rotated to contact the crown 
adjustmentscrew.
To reverse the crown bevel pawl, remove the retaining screw, the 22.5° 
bevel pawl 
51
 and the 30° crown bevel pawl 
52
. Flip the crown bevel 
pawl 
52
 so the 33.86° text is facing up. Reattach the screw to secure the 
22.5° bevel pawl and the crown bevel pawl. The accuracy setting will not 
be affected.
22.5° Bevel Pawls (DWS780, Fig. I)
Your saw is equipped to rapidly and accurately set a 22.5° bevel, left or right. 
The 22.5° bevel pawl 
51
 can be rotated to contact the crown adjustment 
screw 
49
.
Rail Lock Knob (Fig. A1)
The rail lock knob 
7
 allows you to lock the saw head firmly to keep it from 
sliding on the rails 
10
. This is necessary when making certain cuts or when 
transporting the saw.
Grooving Stop (Fig. A2)
The grooving stop 
28
 allows the depth of cut of the blade to be limited. 
The stop is useful for applications such as grooving and tall vertical cuts. 
Rotate the grooving stop forward and adjust the depth adjustment screw 
27
 to set the desired depth of cut. To secure the adjustment, tighten the 
wing nut 
26
. Rotating the grooving stop to the rear of the saw will bypass 
the grooving stop feature. If the depth adjustment screw is too tight to 
loosen by hand, the provided blade wrench 
29
 can be used to loosen 
thescrew.
Lock Down Pin (Fig. A1)
 
WARNING: The lock down pin should be used only when carrying 
or storing the saw. NEVER use the lock down pin for any cutting 
operation.
To lock the saw head in the down position, push the saw head down, push 
the lock down pin 
12
 in and release the saw head. This will hold the saw 
head safely down for moving the saw from place to place. To release, press 
the saw head down and pull the pin out.
Slide Lock Lever (Fig. K2, U) DWS780 only
The slide lock lever 
60
 places the saw in a position to maximize cutting of 
base moulding when cut vertically as shown in Figure U.
Adjustment
Your mitre saw is fully and accurately adjusted at the factory at the time of 
manufacture. If readjustment due to shipping and handling or any other 
reason is required, follow the instructions below to adjust your saw. Once 
made, these adjustments should remain accurate.
Mitre Scale Adjustment (Fig. H, L)
1.  Unlock the mitre lock handle 
21
 and swing the mitre arm until the 
mitre latch button 
22
 locks it at the 0° mitre position. Do not lock the 
mitre lock handle.
2.  Place a square against the saw’s fence and blade, as shown. (Do not 
touch the tips of the blade teeth with the square. To do so will cause an 
inaccurate  measure ment.)
3.  If the saw blade is not exactly perpendicular to the fence, loosen the 
four screws 
46
 that hold the mitre scale 
19
 and move the mitre lock 
handle and the scale left or right until the blade is perpendicular to the 
fence, as measured with the square.
4.  Retighten the four screws. Pay no attention to the reading of the mitre 
pointer 
44
 at this time.
Mitre Pointer Adjustment (Fig. H)
1.  Unlock the mitre lock handle 
21
 to move the mitre arm to the 
zeroposition.
2.  With the mitre lock handle unlocked, allow the mitre latch to snap into 
place as you rotate the mitre arm to zero.
3.  Observe the mitre pointer 
44
 and mitre scale 
19
 shown in figureH. 
If the pointer does not indicate exactly zero, loosen the mitre pointer 
screw 
45
 holding the pointer in place, reposition the pointer and 
tighten the screw.
Bevel Square to Table Adjustment  
(Fig. A1, A2, I, J, M)
1.  To align the blade square to the table, lock the arm in the down 
position with the lock down pin 
12
.
2.  Place a square against the blade, ensuring the square is not on top of a 
tooth (Fig. M).
3.  Loosen the bevel lock knob 
31
 and ensure the arm is firmly against the 
0° bevel stop.
4.  Rotate the 0° bevel adjustment screw (
54
 Fig. I, J) with the 13mm 
blade wrench 
29
 as necessary so that the blade is at 0° bevel to the 
table.
Bevel Pointer Adjustment (Fig. I, J)
If the bevel pointers 
48
 do not indicate zero, loosen each screw 
47
 that 
holds each bevel pointer in place and move them as necessary. Ensure the 
0° bevel is correct and the bevel pointers are set before adjusting any other 
bevel angle screws.
Bevel Stop 45° Right and Left Adjustment 
(Fig. A2, I)
To adjust the right 45° bevel stop:
1.  Loosen the bevel lock knob 
31
 and pull the 0° bevel stop 
32
 to 
override the 0° bevel stop.
2.  When the saw is fully to the right, if the bevel pointer 
48
 does not 
indicate exactly 45°, turn the left 45° bevel adjustment screw 
53
 with 
the 13 mm blade wrench 
29
 until the bevel pointer indicates45°.
To adjust the left 45° bevel stop:
3.  Loosen the bevel lock knob and tilt the head to the left.
4.  If the bevel pointer does not indicate exactly 45°, turn the right 45° 
bevel adjustment screw until the bevel pointer reads 45°.
Adjusting the Bevel Stop to 22.5° (or 30°) 
(Fig. A2, I)
NOTE: Adjust the bevel angles only after performing the 0° bevel angle and 
bevel pointer adjustment.
To set the left 22.5° bevel angle, flip out the left 22.5° bevel pawl 
51
. 
Loosen the bevel lock knob 
31
 and tilt the head fully to the left. If the bevel 
pointer 
48
 does not indicate exactly 22.5°, turn the crown adjustment 
screw 
49
 contacting the pawl with a 10 mm wrench until the bevel pointer 
reads 22.5°.
To adjust the right 22.5° bevel angle, flip out the right 22.5° bevel pawl. 
Loosen the bevel lock knob and pull the 0° bevel stop 
32
 to override the 0° 
bevel stop. When the saw is fully to the right, if the bevel pointer does not 
indicate exactly 22.5°, turn the crown adjustment screw 
49
 contacting the 
pawl with a 10 mm wrench until the bevel pointer indicates exactly 22.5°.
Fence Adjustment (Fig. A1)
The upper part of the fence can be adjusted to provide clearance, allowing 
the saw to bevel to a full 49° both left and right.
1.  To adjust each fence 
14
, loosen the fence adjustment knob 
13
 and 
slide the fence outward.
2.  Make a dry run with the saw turned off and check for clearance.
3.  Adjust the fence to be as close to the blade as practical to provide 
maximum workpiece support, without interfering with arm up and 
down movement.
4.  Tighten the fence adjustment knob securely.
5.  When the bevel operations are complete, relocate the fence.
