Always operate the saw in a well-ventilated area and provide for proper dust removal.
People with electronic devices, such as pacemakers, should consult their
physician(s) before using this product. Operation of electrical equipment in close proximity
to a heart pacemaker could cause interference or failure of the pacemaker.
COMPOUND MITER SAW SAFETY
● USE ONLY CROSS-CUTTING OR COMBINATION SAW BLADES. IMPORTANT:
Improper blades will touch and deflect the blade guard and cause possible injury to the
operator.
● DO NOT operate the miter saw until it is completely assembled and installed according to
these instructions.
● IF YOU ARE NOT thoroughly familiar with the operation of miter saw, seek guidance from
your supervisor, instructor or other qualified person.
● ALWAYS hold the work firmly against the fence and table. DO NOT perform any operation
free hand. Use clamp when ever possible.
● KEEP HANDS out of the path of the saw blade. If the workpiece you are cutting would
cause your hands to be within “no-hands zone” area of the saw blade, the workpiece
should be clamped in place before making the cut.
● MAKE SURE the blade is sharp, runs freely and is free of vibration.
● ALLOW the motor to come up to full speed before starting a cut.
● KEEP THE MOTOR AIR SLOTS CLEAN and free of chips or dust.
● ALWAYS MAKE SURE all handles are tight before cutting, even if the table is positioned in
one of the positive stops.
● MAKE SURE both the blade and the collar are clean and the arbor bolt is tightened
securely.
● USE only blade collars specified for your saw.
● NEVER use blades larger than 10 in. diameter.
● NEVER apply lubricants to the blade when it is running.
● ALWAYS check the blade for cracks or damage before operation. Replace a cracked or
damaged blade immediately.
● NEVER use blades recommended for operation at less than 4800 RPM.
● ALWAYS keep the blade guards in place and use at all times.
● NEVER reach around the saw blade.
● MAKE SURE the blade is not in contact with the workpiece before the switch is turned ON.
● IMPORTANT: After completing the cut, release the trigger switch and wait for the blade to
stop before returning the saw to the raised position.
● 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.
● NEVER cut metals or masonry products with this tool. This miter saw is designed for use
on wood and wood-like products.

kobalttools.com
● TO PREVENT severe cuts or injury, clamp all workpieces that can cause your arms,
hands or fingers to move within 7-1/2 in. of the saw blade.
● PROVIDE adequate support to the sides of the saw table for long workpieces.
● NEVER use the miter saw in an area with flammable liquids or gases.
● NEVER use solvents to clean plastic parts. Solvents could possibly dissolve or otherwise
damage the material.
● SHUT OFF the power before servicing or adjusting the tool.
● DISCONNECT the saw from the power source and clean the machine when finished
using.
● SHOULD any part of your miter saw become missing, damaged, 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.
● Because of the downward cutting motion, your safety requires that you stay very alert to
keeping hands and fingers away from the path that the blade travels.
● Be sure all guards are in place and working. If a guard seems slow to return to its normal
position or “hangs up,” adjust or repair it immediately. Be alert at all times - especially
during repetitive, monotonous operations. Don’t be lulled into carelessness due to a false
sense of security. Blades are extremely unforgiving. Clean the lower guard frequently to
help visibility and movement. Unplug before adjustment or cleaning.
● Abrasive cut-off wheels should not be used on miter saws. Miter saw guards are not
appropriate for abrasive cut-off wheels.
● To avoid loss of control or placing hands in the path of the blade, hold or clamp all material
securely against the fence when cutting. Do not perform operations freehand.
● Support long material at the same height as the saw table.
● Never place your hands or fingers in the path of the blade, or reach in back of the fence.
It’s hazardous to do so. Do not cross arms or hands in front of blade to secure workpiece.
Use clamps if necessary. Saw blades coast after being turned off, to avoid contact with a
coasting blade do not reach into cutting areas until the blade comes to a full stop.
● After completing a cut, release the trigger switch and allow the blade to come to a
complete stop, then raise the saw blade from the workpiece.
● Miter saws have spring loaded saw heads to return the saw head to its up position. Adjust,
repair, or replace the spring mechanism if the saw head does not automatically return to
its up position when released.
● Hold or clamp the work firmly against the fence on the sawed end.
● Lock the miter saw and blades in the down position during transport or when not in use.
● DRY RUN - It is important to know where the blade will intersect with the workpiece
during cutting operations. Always perform a simulated cutting sequence with the power
tool switched OFF to gain an understanding of the projected path of the saw blade. At
some extreme angles, the right or left side fence might have to be removed to ensure
proper clearance prior to making the cut.
Additional warnings are listed throughout this manual. Please review all before
operating this power tool.

SAFETY INFORMATION
ELECTRICAL SPECIFICATIONS AND SAFETY
: POWER SUPPLY AND MOTOR
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, 15A
circuit and use a 15A time-delay fuse or circuit breaker. If power cord is worn or cut or
damaged in any way, have it replaced immediately to avoid shock or fire.
DOUBLE INSULATED
This power tool is double insulated to provide a double thickness of insulation between you
and the tool’s electrical system. All exposed metal parts are isolated from the internal metal
motor components with protective insulation.
REPLACEMENT PARTS: When servicing, use only identical replacement parts list. Refer to
the replacement parts list on pages 4
1
- 48.
POLARIZED PLUGS:
To reduce the risk of electrical shock, this saw has a polarized plug
(one blade is wider than the other). This plug (illustrated at right)
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.
Double insulation does not take the place of normal safety precautions when operating
this tool. To avoid electrocution:
● Use only identical replacement parts when servicing a tool with double insulation. Servicing
should be performed by a qualified technician.
● Do not use power tools in wet or damp locations or expose them to rain or snow.
MOTOR SAFETY PROTECTION
To avoid motor damage, the motor should be blown out or vacuumed frequently to keep
sawdust from interfering with motor ventilation.
● CONNECT this saw to a
1
20V, 15A circuit with a 15A time-delay fuse or circuit breaker.
Using the wrong size fuse can damage the motor.
● If the motor will not 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 TROUBLESHOOTING.
● 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.
● FUSES may “blow” or circuit breakers may trip frequently if:

● MOTOR is overloaded – overloading can occur if you feed too rapidly or make too
many starts/stops in a short time.
● 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.
● IMPROPER or dull saw blades are used.
GUIDELINES FOR EXTENSION CORDS
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 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.

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 15A time-delay fuse. Before connecting the tool to the extension
cord, make sure the saw switch is in the off position. The electric circuit should be rated the
same voltage as is stamped on the motor nameplate. Running at a lower voltage will damage
the motor.
In all cases make certain the receptacle in question is properly grounded. If you are not sure,
have a certified electrician check the receptacle.
