2. Grounded, cord-connected machines intended for
use on a supply circuit having a nominal rating less than
150 volts:
If the machine is intended for use on a circuit that has an
outlet that looks like the one illustrated in Fig. A,the machine
will have a grounding plug that looks like the plug illustrated
in Fig. A. A temporary adapter, which looks like the adapter
illustrated in Fig. B, may be used to connect this plug to a
matching 2-conductor receptacle as shown in Fig. B if a
properly grounded outlet is not available. The temporary
adapter should be used only until a properly grounded outlet
can be installed by a qualified electrician. The green-colored
rigid ear, lug, and the like, extending from the adapter must
be connected to a permanent ground such as a properly
grounded outlet box. Whenever the adapter is used, it must
be held in place with a metal screw.
NOTE: In Canada, the use of a temporary adapter is not
permitted by the Canadian Electric Code.
IN ALL CASES, MAKE CERTAIN THE
RECEPTACLE IN QUESTION IS
PROPERLY GROUNDED. IF YOU ARE NOT SURE HAVE A
QUALIFIED ELECTRICIAN CHECK THE RECEPTACLE.
1. All grounded, cord-connected machines:
In the event of a malfunction or breakdown, grounding
provides a path of least resistance for electric current to
reduce the risk of electric shock. This machine is equipped
with an electric cord having an equipment-grounding
conductor and a grounding plug. The plug must be plugged
into a matching outlet that is properly installed and grounded
in accordance with all local codes and ordinances.
Do not modify the plug provided - if it will not fit the outlet,
have the proper outlet installed by a qualified electrician.
Improper connection of the equipment-grounding
conductor can result in risk of electric shock. The
conductor with insulation having an outer surface that is
green with or without yellow stripes is the equipment-
grounding conductor. If repair or replacement of the electric
cord or plug is necessary, do not connect the equipment-
grounding conductor to a live terminal.
Check with a qualified electrician or service personnel if the
grounding instructions are not completely understood, or if
in doubt as to whether the machine is properly grounded.
Use only 3-wire extension cords that have 3-prong grounding
type plugs and matching 3-conductor receptacles that
accept the machine’s plug, as shown in Fig. A.
Repair or replace damaged or worn cord immediately.

The cuttinghead of your compound miter saw can be
tilted to cut any bevel angle from a 90° straight cut off to
a 45° left bevel angle. Loosen bevel lock handle (A) Fig.
17, tilt the cutting arm to the desired angle, and tighten
the lock handle (A).
Positive stops are provided to rapidly position the saw
blade at 90° and 45° to the table. Refer to the section of
this manual titled “ADJUSTING 90° AND 45° DEGREE
BEVEL STOPS.” The bevel angle of the cutting arm is
determined by the position of the pointer (B) Fig. 17 on
the scale (C).
In addition, a triangle indicator is provided on the bevel
scale at 33.86° for cutting crown moulding. Refer to the “CUTTING CROWN MOULDING” section of this manual.

TYPICAL OPERATIONS AND HELPFUL HINTS
IF THE WORKPIECE CAUSES YOUR
HAND TO BE IN THE HAZARD ZONE
OF OF THE SAW BLADE, CLAMP THE
WORKPIECE IN PLACE BEFORE
MAKING THE CUT.
1. Before cutting, make certain that the cutting arm
and table are at the correct settings and firmly
locked in place.
2. Place the workpiece on the table and hold or clamp
it firmly against the fence (Fig. 31).
3. For best results, cut at a slow, even cutting rate.
4. Never attempt freehand cutting (wood that is not
held firmly against the fence and table).
AUXILIARY WOOD FENCE
Multiple or repetitive cut-off operations that result in
small cut-off pieces (one inch or less) can cause the saw
blade to catch the cut-off pieces and project them out
of the machine or into the blade guard and housing,
possibly causing damage or injury.
TO LIMIT THE POSSIBILITY OF
PERSONAL INJURY OR BLADE
GUARD DAMAGE, MOUNT AN
AUXILIARY WOOD FENCE ON YOUR
SAW.
Holes are provided in the fence to attach an auxiliary fence (A) Fig. 32. This auxiliary fence is constructed of straight
wood approximately 1/2" thick by 3" high by 20" long.
NOTE: The auxiliary fence (A) is used ONLY with the saw blade in the 0° bevel position (90° to the table). When bevel
cutting (blade tilted), remove the auxiliary fence.

The tension of the cuttinghead return spring was adjusted
at the factory so that the cuttinghead returns to the “up”
position after a cut has been made. If it becomes neces-
sary to adjust the spring tension:

GENERAL CUTTING OPERATIONS
1. Your machine has the capacity to cut standard 2 x 4’s lying flat or on edge, at the 45 degree right and left miter angles (Figs.
A1 and A2).
2. A standard 2 x 6 can be cut in the 90 degree straight cut-off position in one pass (Fig. A3).
3. Cutting a standard 4 x 4 can be accomplished with one pass (Fig. A4).
4. This machine has the capacity to accurately cut crown mouldings and other bevel-type cuts (Fig. A5).
5. Cutting various sizes of plastic pipe is an easy job with this machine (Fig. A6).

CUTTING BOWED MATERIAL
When cutting flat pieces, first check to see if the material is bowed. If it is, make sure the material is positioned on the
table as shown in Fig. 35.
If the material is positioned the wrong way (Fig. 36), the workpiece will pinch the blade near the completion of the cut.
RIGHT WRONG
Fig. 35 Fig. 36
CUTTING ALUMINUM
Aluminum extrusions used for making aluminum screens and storm windows can easily be cut with your compound
miter saw. When cutting aluminum extrusions, or other sections that can be cut with a saw blade and are within the
capacity of the machine, position the material so the blade is cutting through the smallest cross-section (Fig. 33). The
wrong way to cut aluminum angles is illustrated in Fig. 34. Be sure to apply a stick wax to the blade before cutting
aluminum stock. This stick wax is available at most industrial mill supply houses. The wax provides proper lubrication
and keeps chips from adhering to the blade.
Never apply lubricant to the blade while the machine is running.

WORK SUPPORT EXTENSIONS
For support when cutting long pieces, construct a work
support extension. Fig. 39 illustrates the miter saw
mounted on two standard 2 x 4’s (A). Fasten the four
mounting legs (two of which are shown at (B) Fig. 39 to
the 2 x 4’s, using four screws (not supplied) through the
four holes in the mounting legs. The length of the 2 x 4’s
(A) can vary, depending on the workpiece.
NOTE: Ensure that the top of the support 2 x 4’s (C)
are level with the miter saw table. This is critical
because the distance from the top of the 2 x 4’s (A) to the
miter saw table varies from saw to saw. In most cases,
standard 2 x 4’s (C) can used. If these are too high, cut
them to fit. If the 2 x 4’s are too low, use 2 x 6’s. If these
are high, cut them to the correct height.

CUTTING CROWN MOULDING
One of the many features of the saw is the ease of cutting crown moulding. The following is an example of cutting both inside and
outside corners on 52°/38° wall angle crown moulding.
1. Move the table to the 31.62° right miter position and lock the table in position. NOTE: A positive stop is provided to find this angle
quickly.
2. Tilt the saw blade to the 33.86° left bevel position and tighten bevel lock handle. NOTE: A triangle indicator is provided on the
bevel scale to find this angle quickly.
3. Place the crown moulding on the table with the CEILING EDGE of the moulding against the fence, and make the cut, as shown
in Fig. 40.
NOTE: The piece of crown moulding used for the outside corner will always be on the right hand side of the blade, as shown at (A)
Fig. 40. The piece of crown moulding used for the inside corner will always be on the left hand side of the blade, as shown at (B)
Fig. 40.
4. To make the matching halves of the inside and outside corners, rotate the table to the 31.62° left miter position.
NOTE: A positive stop is provided to find this angle quickly. The saw blade is already tilted to the 33.86° left bevel position from the
previous cut.
5. Place the crown moulding on the table with the WALL EDGE of the crown moulding against the fence and make the cut. Again,
the piece of crown moulding used for the outside corner will always be on the right side of the blade, as shown at (C) Fig. 41. The
piece of crown moulding used for the inside corner will always be on the left side of the blade, as shown at (D) Fig. 41.
6. Fig. 42 illustrates the two outside corner pieces; (A) being the piece cut at (A) Fig. 40 and (C) being the piece cut at (C) Fig. 41.
7. Fig. 43 illustrates the two inside corner pieces; (B) being the piece cut at (B) Fig. 40, and (D) being the piece cut at (D) Fig. 41.
45-45 CROWN MOULDING
NOTE: If you are cutting crown moulding that is 45°-45°, follow the same procedure above, with the exception that the bevel position
will always be at 30° and the miter position will be 35-1/4° to the right or left.
OTHER ANGLES
NOTE: The above instructions are assuming the angle between the walls is 90°. If you need help cutting crown moulding set at angles
other than 90°, see the instruction sheet “CUTTING CROWN MOULDING” on the Delta Machinery web site at
www.deltamachinery.com.

MAINTENANCE
CHANGING THE BLADE
Use only cross-cutting saw blades.
When using carbide-tipped blades, do not use blades with deep gullets as they can deflect and
contact the guard.
Use only 10" diameter saw blades rated for 5200 rpm or higher, and have 5/8" diameter arbor holes.
Disconnect machine from power source.
The no-load speed of this machine is 5200 rpm.
REMOVE WRENCHES (A) FIG. 44 AND (A) FIG. 45 BEFORE STARTING THE MACHINE.
1. Remove the screw (A) Fig. 42 and rotate the cover (B) Fig. 43 to the rear.
2. To remove the saw blade, insert the hex wrench (A) Fig. 42 into the hex hole located on the rear end of the motor
shaft to keep the shaft from turning.
3. Use a wrench (A) Fig. 44 to loosen the arbor screw (C) by turning it clockwise.
4. Remove the arbor screw (C) Fig. 45, outside blade flange (B), and saw blade from the saw arbor.
5. Attach the new saw blade making certain that the teeth of the saw blade are pointing down at the front. Attach
the outside blade flange (B) Fig. 45, then the arbor screw (C), and turn it counterclockwise, using the wrench (A)
Fig. 45. At the same time, use the hex wrench (A) Fig. 42 to keep the arbor from turning.

BRUSH INSPECTION
AND REPLACEMENT
Brush life varies. It depends on the load on the motor.
Check the brushes after the first 50 hours of use for a
new machine or after a new set of brushes has been
installed. After the first check, examine them after about
10 hours of use until such time that replacement is
necessary. To inspect the brushes, proceed as follows:
DISCONNECT MACHINE FROM POWER
SOURCE.
1. Remove three screws (A) Fig. 46 and remove motor
cover (B).
3. Fig. 48 illustrates one of the brushes (E) removed
from the holder (C). When the carbon on either brush (E)
is worn to 3/16″in length or if either spring (F) or shunt
wire is burned or damaged in any way, replace both
brushes. If the brushes are found to be serviceable after
re-moving, reinstall them in the same position.
2. The brushes are located in the two holders (C) Fig. 47.
Remove spade type terminal connector (D) and pull out
brush holders (C).
