ELECTRICAL REQUIREMENTS AND SAFETY
NOTE: When using an extension cord on a
circuit with a #14 wire, the extension cord must
GROUNDING INSTRUCTIONS
not exceed 25 feet in length. Before connecting
the motor 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. This tool is intended for
use on a circuit that has a receptacle like the one
illustrated in Fig. 1.
IN THE EVENT OF A MALFUNCTION OR
BREAKDOWN, grounding provides a path of
least resistance for electric currents and reduces
the risk of electric shock. This tool is equipped
with an electrical cord that has an equipment-
grounding conductor and a grounding plug. The
plug must be plugged into a matching receptacle
that is properly installed and grounded in
accordance with all local codes and ordinances.
Fig. 1 shows a three-pronged electrical plug and
receptacle that has a grounding conductor. If a
properly grounded receptacle is not available,
an adapter (Fig. 2) can be used to temporarily
connect this plug to a two-contact grounded
receptacle. The adapter (Fig. 2) has a rigid lug
extending from it that MUST be connected to
a permanent earth ground, such as a properly
grounded receptacle box.
DO NOT MODIFY THE PLUG PROVIDED.
If it will not fit the receptacle, have the proper
receptacle installed by a qualified electrician.
IMPROPER CONNECTION of the equipment
grounding conductor can result in risk of electric
shock. The conductor with the green insulation
(with or without yellow stripes) is the equipment
grounding conductor. If repair or replacement of
the electrical cord or plug is necessary, do not
connect the equipment grounding conductor to a
live terminal.
WARNING
!
In all cases, make certain the receptacle is
properly grounded. If you are not sure, have a
qualified electrician check the receptacle.
CHECK with a qualified electrician or service
person if you do not completely understand the
grounding instructions, or if you are not certain
the tool is properly grounded.
WARNING
!
This tool is for indoor use only. Do not
expose to rain or use in damp locations.
USE only three-wire extension cords that have
three-pronged grounding plugs with three-pole
receptacles that accept the tool’s plug. Repair or
replace damaged or worn cords immediately.

PLAN YOUR WORK
Make sure there are no gaps between the
workpiece, fence and table that will let the
workpiece shift after it is cut.
Keep the cut off piece free to move sideways
after it is cut off. Otherwise, it could get
wedged against the blade and thrown
violently.
Only the workpiece should be on the saw
table.
Secure work. Use clamps or a vise to help
hold the work when it’s practical.
●
Use the right tool. Don’t force a tool or
attachment to do a job it was not designed
to do. Use a different tool for any workpiece
that can’t be held in a solidly braced, fixed
position.
CAUTION
!
●
●
This machine is not designed for cutting
masonry, masonry products, ferrous metals
(steel, iron, and iron-based metals.) Use
this miter saw to cut only wood, wood-
like products, or non-ferrous metals. Other
material may shatter, bind the blade, or create
other dangers. Remove all nails that may be
in the workpiece to prevent sparking that
could cause a fire. Remove dust bag when
cutting non-ferrous metals.
USE EXTRA CAUTION WITH LARGE OR ODD
SHAPED WORKPIECES.
●
Use extra supports (tables, sawhorses,
blocks, etc.) for workpieces large enough to
tip.
Never use another person as a substitute for
a table extension, or as an additional support
for a workpiece that is longer or wider than
the basic miter saw table, or to help feed,
support, or pull the workpiece.
Do not use this saw to cut small pieces. If the
workpiece being cut would cause your hand
or fingers to be within 6-3/4 inches of the saw
blade the workpiece is too small. Keep hands
and fingers out of the “no hands zone” area
marked on the saw table.
When cutting odd shaped workpieces, plan
your work so it will not bind in the blade and
cause possible injury. Molding, for example,
must lie flat or be held by a fixture or jig that
will not let it move when cut.
●
DRESS FOR SAFETY
Any power tool can throw foreign
objects into the eyes. This can result in
permanent eye damage. Everyday
eyeglasses have only impact resistant lenses and
are not safety glasses. Glasses or goggles not
in compliance with ANSI Z87.1 could seriously
injure you when they break.
●
●
Do not wear loose clothing, gloves, neckties
or jewelry (rings, watches). They can get
caught and draw you into moving parts.
Wear non-slip footwear.
●
●
●
●
●
●
Tie back long hair.
Roll long sleeves above the elbow.
Noise levels vary widely. To avoid possible
hearing damage, wear ear plugs when using
any miter saw.
For dusty operations, wear a dust mask along
with safety goggles.
Properly support round material such as
dowel rods, or tubing, which have a tendency
to roll when cut, causing the blade to “bite”.
●
! WARNING
To avoid injury, follow all applicable safety
instructions, when cutting non-ferrous
metals:
INSPECT YOUR WORKPIECE
Make sure there are no nails or foreign objects in
the part of the workpiece being cut.
Plan your work to avoid small pieces that may
bind, or that are too small to clamp and get a
solid grasp on.
Plan the way you will grasp the workpiece from
start to finish. Avoid awkward operations and
hand positions. A sudden slip could cause your
fingers or hand to move into the blade.
●
●
●
Use only saw blades specifically
recommended for non-ferrous metal cutting.
Do not cut metal workpieces that must be
hand held. Clamp workpieces securely.
Cut non-ferrous metals only if you are under
the supervision of an experienced person and
the dust bag has been removed from the saw.
WHEN SAW IS RUNNING
DO NOT OVER-REACH
Keep good footing and balance. Keep your face
and body to one side, out of the line of a possible
kickback. NEVER stand in the line of the blade.
!
WARNING
Do not allow familiarity from frequent use of
your miter saw to result in a careless mistake.
A careless fraction of a second is enough to
cause a severe injury.
Before cutting, if the saw makes an unfamiliar
noise or vibrates, stop immediately. Turn the
saw OFF. Unplug the saw. Do not restart until
finding and correcting the problem.
Never cut freehand:
●
Brace your workpiece firmly against the fence
and table stop so it will not rock or twist during
the cut.
Make sure there is no debris between the
workpiece and the table or fence.

To avoid injury from unexpected starting
or electrical shock, unplug the power cord
before working on the saw.
When cleaning the lower guard, unplug the
saw from the power source receptacle to
avoid unexpected startup.
!
WARNING
EMPTYING SAWDUST BAG
For your safety, this saw is double-insulated.
To avoid electrical shock, fire or injury, use
only parts identical to those identified in the
parts list. Reassemble exactly as the original
assembly to avoid electrical shock.
Periodically, sawdust will accumulate under the
work table and base. This could cause difficulty
in the movement of the worktable when setting
up a miter cut. Frequently blow out or vacuum up
the sawdust.
!
WARNING
REPLACING CARBON BRUSHES (FIG. DD)
Replace both carbon brushes when either has
less than 1/4 in. length of carbon remaining, or
if the spring or wire is damaged or burned. To
inspect or replace brushes, first unplug the saw.
Then remove the black plastic cap (1) on the
side of the motor (2). Remove the cap cautiously,
because it is springloaded. Then pull out the
brush and replace. Replace for the other side.
To reassemble reverse the procedure. The ears
on the metal end of the assembly go in the same
hole the carbon part fits into. Tighten the cap
snugly, but do not overtighten.
If blowing sawdust, wear proper eye
protection to keep debris from blowing into
eyes.
LUBRICATION (FIG. EE)
All the motor bearings in this tool are lubricated
with a sufficient amount of high grade lubricant
for the life of the unit under normal operating
conditions; therefore, no further bearing
lubrication is required.
Lubricate the following as necessary:
Chop pivot: Apply light machine oil to points
indicated in illustration.
NOTE: To reinstall the same brushes, first make
sure the brushes go back in exactly the way they
came out. This will avoid a break-in period that
reduces motor performance and increases wear.
Chop and Central pivot: Apply light machine oil
to points indicated in illustration.
