SAFETY GUIDELINES - DEFINITIONS
CALIFORNIA PROPOSITION 65
Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains
chemicals known to cause cancer, birth defects or other reproductive harm. Some examples of these
chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks and cement and other masonry products, and
• arsenic and chromium from chemically-treated lumber (CCA).
Your risk from these exposures varies, depending on how often you do this type of work. To reduce your exposure to these
chemicals: work in a well ventilated area, and work with approved safety equipment, such as those dust masks that are specially
designed to filter out microscopic particles.
• Avoid prolonged contact with dust from power sanding, sawing, grinding, drilling, and other construction activities. Wear protective
clothing and wash exposed areas with soap and water. Allowing dust to get into your mouth, eyes, or lay on the skin may promote
absorption of harmful chemicals.

14. NEVER START THE TOOL with the blade against the
workpiece. The workpiece can be thrown, causing
serious injury.
15. KEEP ARMS, HANDS, AND FINGERS away from the
blade to prevent severe cuts. Clamp all workpieces
that would cause your hand to be in the “Table
Hazard Zone” (within the red lines).
16. WHEN CUTTING WITH A COMPOUND SLIDING
MITER SAW, PUSH THE SAW FORWARD (AWAY
FROM YOU) and toward the fence. Pulling the saw
toward you can cause the saw to kick upward and
toward you.
17. WHEN USING A SLIDING MITER SAW AS A REGULAR
MITER SAW, LOCK THE SLIDE MECHANISM IN PLACE.
If the slide mechanism is not locked, the saw can kick
back toward you.
18. ALLOW THE MOTOR TO COME TO FULL SPEED
prior to starting cut. Starting the cut too soon can
cause damage to the machine or blade and/or
serious injury.
19. NEVER REACH AROUND or behind the saw blade.
A moving blade can cause serious injury.
20. NEVER CUT FERROUS METALS or masonry. Either
of these can cause the carbide tips to fly off the blade
at high speeds causing serious injury.
21. NEVER CUT SMALL PIECES. Cutting small pieces
can cause your hand to move into the blade, resulting
in serious injury.
22. NEVER LOCK THE SWITCH in the “ON” position.
Setting up the next cut could cause your hand to
move into the blade, resulting in severe injury.
23. NEVER APPLY LUBRICANT to a running blade.
Applying lubricant could cause your hand to move

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 equipmentgrounding 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 equipmentgrounding 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.

You can tilt the cuttinghead of your compound miter saw to cut
any bevel angle from a 90° straight cut off to a 45° left bevel
angle. Loosen the bevel lock handle (A) Fig. 18, tilt the cutting
arm (B) 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° BEVEL STOPS.” The bevel
angle of the cuttinghead is determined by the position of the
pointer (C) Fig. 18 on the scale (D).
A triangle indicator is provided on the bevel scale at the 33.86°
bevel angle for cutting crown moulding. Refer to the
“CUTTING CROWN MOULDING” section of this manual.
A rear support bar (A) Fig. 19 is provided to prevent the machine from tipping to the rear when the cuttinghead returns to the up
position. For maximum support, pull the bar (A) out as far as possible.
You can also use the support bar (A) Fig. 20 to carry the machine.

In order that the saw can bevel to a full 47 degrees left, the left side of the fence can be adjusted to the left to provide clearance. To
adjust the fence, loosen the plastic knob shown in Figure 22 and slide the fence to the left. Make a dry run with the saw turned 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 arm up & down movement. Tighten knob securely. When the bevel operations are complete, don’t forget to relocate the
fence to the right.
NOTE: The guide groove in the left side fence can become clogged with sawdust. If you notice that it is becoming clogged, use a stick
or some low pressure air to clear the guide groove.

TYPICAL OPERATIONS AND HELPFUL HINTS
1. Before cutting, make certain that the cutting arm and table are at their correct settings and firmly locked in place.
2. Place the workpiece on the table and hold it firmly against the fence.
3. Keep your hands out of the “Hazard Zone”.
4. For best results, cut at a slow, even cutting rate.
5. Never attempt freehand cutting (wood that is not held firmly against the fence and table).
Holes are provided in the fence to attach an auxiliary fence (A) Fig. 30. This auxiliary fence is constructed of straight wood
approximately 1/2" thick by 3" high by 20" long.
MACHINE USE
AUXILIARY WOOD FENCE
When performing multiple or repetitive operations that result in small cut-off pieces (one inch or less), the
saw blade can catch the cut-off pieces and project them out of the machine or into the blade guard and housing, causing
damage or injury. To limit the risk, mount an auxiliary wood fence on your saw (Fig. 30).
NOTE: The auxiliary fence (A) is used ONLY with the saw blade in the 0° bevel position (90° to the table). When you bevel cut (blade
tilted), remove the auxiliary fence.

GENERAL CUTTING OPERATIONS
1. Your machine has the capacity to cut standard 2 x 4’s, lying flat or on edge, at the 45° right and left miter angles (Fig. A1 & A2).
2. A standard 2 x 6 can be cut in the 90° 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). Hold pipe firmly against the fence. Use extra care
and secure pipe firmly when cutting angles into pipe.

CUTTING BOWED MATERIAL
Check to see if your workpiece is bowed. If it is, make sure the material is positioned on the table as shown in Fig. 33.
If the material is positioned the wrong way, as shown in Fig. 34, the workpiece will pinch the blade near the completion of the cut.

WORK SUPPORT EXTENSIONS
For support when cutting long pieces, a work support
extension can be constructed. Fig. 35 illustrates the miter saw
mounted to two standard 2 x 4’s (A). Fasten the four mounting
legs (two of which are shown at (B) Fig. 36 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 kind of work that will need to be cut.
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 the 2 x 4s (C) to provide this height or use other
properly-sized wood.
CUTTING ALUMINUM
Aluminum extrusions such as 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. 31). The wrong way to cut
aluminum angles is illustrated in Fig. 32. 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.

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. 36.
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. 36. 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. 36.
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. 37. 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. 37.
6. Fig. 38 illustrates the two outside corner pieces; (A) being the piece cut at (A) Fig. 36 and (C) being the piece cut at (C) Fig. 37.
7. Fig. 39 illustrates the two inside corner pieces; (B) being the piece cut at (B) Fig. 36, and (D) being the piece cut at (D) Fig. 37.
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.

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 which are
rated for 5200 rpm or higher and have 5/8"
diameter arbor holes.
1. Remove screw (A) Fig. 40 and rotate cover (B) to the rear
(Fig. 41).
2. To remove the saw blade, insert the hex wrench (C)
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 (G) Fig. 43 to loosen the arbor screw (E) by
turning it clockwise.
4. Remove the arbor screw (E) Fig. 43, the outside blade
flange (F), and the saw blade from the saw arbor.
5. Attach the new saw blade
making certain that the teeth of
the saw blade are pointing down (Fig. 43). Place the
outside blade flange (F) on the arbor, and attach the arbor
screw (E) by turning it counter-clockwise using the wrench
(G) Fig. 43. At the same time, use the hex wrench (C) Fig.
42 to keep the arbor from turning.
6. Rotate the cover back to the front and replace the screw
that was removed in STEP 1.

1. Remove three screws (A) Fig. 44 and remove the motor
cover (B).
2. The brushes are located in the two holders (C) Fig. 45.
Remove spade type terminal connector (D) and pull out
brush holders (C).
3. Fig. 46 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.
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 a replacement is
necessary. To inspect the brushes:
Use only mild soap and damp cloth to clean the tool. Never let any liquid get inside the tool; never immerse any part of the tool into a
liquid.
IMPORTANT
To assure product SAFETY and RELIABILITY, repairs, maintenance and adjustment (including brush inspection and replacement)
should be performed by authorized service centers or other qualified service organizations, always using identical replacement parts.
