SPECIFIC SAFETY INSTRUCTIONS FOR THIS COMPOUND MITER SAW
1. USE ONLY CROSS-CUTTING SAW BLADES. When using carbide tipped blades, make sure they have a
negative hook angle.
IMPORTANT: DO NOT USE THIN KERF BLADES-
they can deflect and contact guard and can cause
possible injury to the operator.
2. DO NOT operate the miter saw until it is completely assembled and installed according to these
instructions.
3. IF YOU ARE NOT thoroughly familiar with the operation of miter saws, seek guidance from your supervisor,
instructor, or other qualified person.
4. ALWAYS hold the work firmly against the fence and table. DO NOT perform any operation free hand (use
clamp wherever possible).
5. KEEP HANDS out of the path of the saw blade. If the
workpiece you are cutting would cause your hands to
be within 7-1/4" inches of the saw blade, the workpiece should be clamped in place before making the cut.
6. BE SURE the blade is sharp, runs freely, and is free of vibration.
18.MAKE SURE the blade is not contacting the workpiece before the switch is turned ON.
19.IMPORTANT: After completing the cut, release the power switch and wait for the blade to stop before
returning the saw to the raised position.
20.MAKE SURE the blade has come to a complete stop before removing or securing the workpiece, changing
the workpiece angle, or changing the angle of the
blade.
21.NEVER cut metals or masonry products with this tool.
This miter saw is designed for use on wood and wood-like products.
22.NEVER cut small pieces. Ifthe workpiece being cut
would cause your hand or fingers to be within 7-1/4"
inches of the saw blade the workpiece is too small.
23.PROVIDE adequate support to the sides of the saw
table for long work pieces.
24.NEVER use the miter saw in an area with flammable liquids or gases.
25.NEVER use solvents to clean plastic parts. Solvents
could possibly dissolve or otherwise damage the
material.
7. ALLOW the motor to come up to full speed before starting a cut.
8. KEEP THE MOTOR AIR SLOTS CLEAN and free of chips or dust.
9. ALWAYS MAKE SURE all handles are tight before cutting, even if the table is positioned in one of the
positive stops.
10.BE SURE both the blade and the collar are clean and the arbor bolt is tightened securely.
11.USE only blade collars specified for your saw.
12. NEVER use blades larger or smaller in diameter than
10-inches.
13. NEVER apply lubricants to the blade when it is
running.
14. ALWAYS check the blade for cracks or damage before
operation. Replace a cracked or damaged blade
immediately.
15. NEVER use blades recommended for operation at less
than 4800 RPM.
16.ALWAYS keep the blade guards in place and use at all times.
17.NEVER reach around the saw blade.
26.SHUT OFF the power before servicing or adjusting the tool.
27.DISCONNECT the saw from the power source and clean the machine when finished using.
28.MAKE SURE the work area is clean before leaving the
machine.
29.SHOULD any part of your miter saw be missing, damaged, or fail in any way, or any electrical
component fail to perform properly, shut off the switch and remove the plug from the power supply outlet.
Replace missing, damaged, or failed parts before resuming operation.
POWER SUPPLY AND MOTOR SPECIFICATIONS The AC motor used in this saw is a universal,
nonreversible type. See "MOTOR" in the "PRODUCT SPECIFICATIONS" section on page 2.
To avoid electrical hazards, fire hazards, or damage to the tool, use proper circuit protection. Your saw is wired at the
factory for 120V operation. Connect to a 120V, 15 Amp
circuit and use a 15 amp. time delay fuse or circuit breaker. To avoid shock or fire, if power cord is worn or cut, or
damaged in any way, have it replaced immediately.
ELECTRICALREQUIREMENTS - cont'd
DOUBLE INSULATED [] The power tool is double insulated to provide a double
thickness of insulation between you and tool's electrical system. All exposed metal parts are isolated from the
internal metal motor components with protecting insulation.
Replacement parts - When servicing use only identical replacement parts.
Polarized plugs - This saw has a plug that looks like the one shown below:
.... _:: :!i¸
To reduce the risk of electrical shock, this saw has a polarized plug (one blade is wider than the other). This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still
does not fit, contact a qualified electrician to install the proper outlet. Do not change the plug in any way.
4. FUSES may "blow" or circuit breakers may trip frequently if:
a. MOTOR is overloaded - overloading can occur if
you feed too rapidly or make too many start/stops
in a short time.
b. LINE VOLTAGE is more than 10% above or below
the nameplate voltage rating. For heavy loads, the voltage at motor terminals must equal the voltage specified on the nameplate.
c. IMPROPER or dull saw blades are used.
5.Most motor troubles may be traced to loose or incorrect connections, overload, low voltage or inadequate power
supply wiring. Always check the connections, the load and supply circuit if the motor doesn't run well. Check minimum gauge for the length of cord you are using on
the chart below.
GUIDELINES FOR EXTENSION CORDS Use a proper extension cord. Make sure your extension
cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in
line voltage, resulting in loss of power and cause overheating. The table below shows the correct size to use
depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gauge. The smaller the gauge number, the heavier the cord.
Double insulation does not take the place of normal safety precautions when operating this tool.
To avoid electrocution:
1. Use only identical replacement parts when servicing a tool with double insulation. Servicing should be performed
by a qualified technician.
2. Do not use power tools in wet or damp locations or expose them to rain or snow.
MOTOR SAFETY PROTECTION
IMPORTANT:
To avoid motor damage, the motor should be blown out or vacuumed frequently to keep sawdust from interfering with
the motor ventilation.
1.CONNECT this saw to a 120'7, 15 amp. circuit with a 15 amp. time delay fuse or circuit breaker. Using the wrong size fuse can damage the motor.
2.If the motor won't start, release the trigger switch immediately. UNPLUG THE SAW. Check the saw blade to make sure it turns freely. If the blade is free, try to
start the saw again. If the motor still does not start, refer to the "TROUBLESHOOTING GUIDE"
3.If the tool suddenly stalls while cutting wood, release the trigger switch, unplug the tool, and free the blade from
the wood. The saw may now be started and the cut finished.
Be sure your extension cord is properly wired and in good condition. Always replace a damaged extension cord or have it repaired by a qualified person before using it.
Protect your extension cords from sharp objects, excessive heat and damp or wet areas.
Use a separate electrical circuit for your tools. This circuit must not be less than # 12 wire and should be
protected with a 15 Amp time delay fuse. Before connecting the tool to the power line, make sure the switch
is in the OFF position and the electric current is rated the same as the current stamped on the motor nameplate,
running at a lower voltage will damage the motor.

Read warnings and conditions on your CARBIDE TIPPED SAW BLADE. Do not operate the saw without the proper saw blade guard in place. Carbide is a very hard but brittle
material. Care should be taken while mounting, using, and storing carbide tipped blades to prevent accidental damage. Slight shocks, such as striking the tip while
handling, can seriously damage the blade. Foreign objects in the workpiece, such as wire or nails, can also cause tips to crack or break off. Before using, always visually
examine the blade and tips for bent teeth, cracks, breakage, missing or loose tips, or other damage. Do not use if damage is suspected. Failure to heed safety
instructions and warnings can result in serious bodily injury.
UNPACKING YOUR MITER SAW
To avoid injury from unexpected starting or electrical shock, do not plug the power cord into a source of power during
unpacking and assembly. This cord must remain unplugged whenever you are adjusting/assembling the
saw,
,
Place the saw on a secure stationary work surface.
