GENERAL POWER TOOL SAFETY WARNINGS
The term “power tool” in the warnings refers to your mains-operated (corded) power tool or BATTERY-operated (cordless) power
tool.
1. Work area safety
a. Keep work area clean and well lit. Cluttered or dark areas invite accidents.
b. Do not operate power tools in explosive atmospheres, such as in the presence of ammable liquids,
gases or dust. Power tools create sparks which may ignite the dust or fumes.
c. Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.
2. Electrical safety
a. Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter with
earthed (grounded) power tools. Unmodied plugs and matching outlets will reduce risk of electric shock
b. Avoid body contact with earthed or grounded surfaces, such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
c. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of
electric shock.
d. Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord
away from heat oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric
shock.
e. When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord
suitable for outdoor use reduces the risk of electric shock.
f. If operating a power tool in a damp location is unavoidable, use a ground fault circuit interrupter (GFCI)
protected supply. Use of an GFCI reduces the risk of electric shock.
3. Personal safety
a. Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use
a power tool while you are tired or under the inuence of drugs, alcohol or medication. A moment of
inattention while operating power tools may result in serious personal injury.
b. Use personal protective equipment. Always wear eye protection. Protective equipment such as dust mask,
non-skid safety shoes, hard hat, or hearing protection used for appropriate conditions will reduce personal injuries.
c. Prevent unintentional starting. Ensure the switch is in the o-position before connection to power
source, picking up, or carrying the tool. Carrying power tools with your nger on the switch or energising power
tools that have the switch on invites accidents.
d. Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a
rotating part of the power tool may result in personal injury.
e. Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool
in unexpected situations.
f. Dress properly. Do not wear loose clothing or jewelery. Keep your hair, clothing and gloves away from
moving parts. Loose clothes, jewelery or long hair can be caught in moving parts.
g. If devices are provided for the connection of dust extraction and collection facilities, ensure these are
connected and properly used. Use of dust collection can reduce dust-related hazards.
h. Do not let familiarity gained from frequent use of tools allow you to become complacent and ignore tool
safety principles. A careless action can cause severe injury within a fraction of a second.
4. Power tool use and care
a. Do not force the power tool. Use the correct power tool for you application. The correct power tool will do
the job better and safer at the rate for which it was designed.
b. Do not use the power tool if the switch does not turn it on and o. Any power tool that cannot be controlled
with the switch is dangerous and must be repaired.
c. Disconnect the plug from the power source before making any adjustments, changing accessories, or
storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
d. Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power
tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
e. Maintain power tools and accessories. Check for misalignment or binding of moving parts, breakage of
parts and any other condition that may aect the power tool’s operation. If damaged, have the power
tool repaired before use. Many accidents are caused by poorly maintained power tools.
Read all safety warnings, instructions, illustrations and specications provided with this power tool.
Failure to follow all instructions listed below may result in electric shock, re and/or serious injury.
Save all warnings and instructions for future reference.

SAFETY INSTRUCTIONS FOR MITER SAWS
f. Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to
bind and are easier to control.
g. Use the power tool, accessories and tools bits etc. in accordance with these instructions, taking into
account the working conditions and the work to be performed. Use of the power tool for operations dierent
from those intended could result in a hazardous situation.
h. Keep Handles and grasping surfaces dry, clean and free from oil and grease. Slippery handles and grasping
surfaces do not allow for safe handling and control of the tool in unexpected situations.
5. Service
a. Have your power tool serviced by a qualied repair person using only identical replacement parts. This
will ensure that the safety of the power tool is maintained.
1.
a. Miter saws are intended to cut wood or wood-like products, they cannot be used with abrasive cut-o
wheels for cutting ferrous material such as bars, rods, studs, etc. Abrasive dust causes moving parts such as
the lower guard to jam. Sparks from abrasive cutting will burn the lower guard, the kerf insert and other plastic parts.
b. Use clamps to support the workpiece whenever possible. If supporting the workplace by hand, you must
always keep your hand at least 100mm from either side of the saw blade. Do not use this saw to cut
pieces that are too small to be securely clamped or held by hand. If your hand is placed too close to the saw
blade, there is an increased risk of injury from blade contact.
c. The workpiece must be stationary and clamped or held against both the fence and the table. Do not
feed the workpiece into the blade or cut “freehand” in any way. Unrestrained or moving workpieces could be
thrown at high speeds, causing injury.
d. Push the saw through the workpiece. Do not pull the saw through the workpiece. To make a cut, raise
the saw head and pull it out over the workpiece without cutting, start the motor, press the saw head
down and push the saw through the workpiece. Cutting on the pull stroke is likely to cause the saw blade to
climb on top of the workpiece and violently throw the blade assembly towards the operator.
e. Never cross your hand over the intended line of cutting either in front or behind the saw blade.
Supporting the workpiece “cross handed” i.e. holding the workpiece to the right of the saw blade with your left hand
or vice versa is very dangerous.
f. Do not reach behind the fence with either hand closer than 100mm from either side of the saw blade, to
remove wood scraps, or for any other reason while the blade is spinning. The proximity of the spinning saw
blade to your hand may not be obvious and you may be seriously injured.
g. Inspect your workpiece before cutting. If the workpiece is bowed or warped, clamp it with the outside
bowed face toward the fence. Always make certain that there is no gap between the workpiece, fence
and table along the line of the cut. Bent or warped workpieces can twist or shift and may cause binding on the
spinning saw blade while cutting. There should be no nails or foreign objects in the workpiece.
h. Do not use the saw until the table is clear of all tools, wood scraps, etc., except for the workpiece. Small
debris or loose pieces of wood or other objects that contact the revolving blade can be thrown with high speed.
i. Cut only one workpiece at a time. Stacked multiple workpieces cannot be adequately clamped or braced and may
bind on the blade or shift during cutting.
j. Ensure the miter saw is mounted or placed on a level, rm work surface before use. A level and rm work
surface reduces the risk of the miter saw becoming unstable.
k. Plan your work. Every time you change the bevel or miter angle setting, make sure the adjustable fence
is set correctly to support the workpiece and will not interface with the blade or the guarding system.
Without turning the tool “ON” and with no workpiece on the table, move the saw blade through a complete simulated
cut to assure there will be no interference or danger of cutting the fence.
l. Provide adequate support such as table extensions, saw horses, etc. for a workpiece that is wider or
longer than the table top. Workpieces longer or wider than the miter saw table can if not securely supported. If the cut-o
piece or workpiece tips, it can lift the lower guard or be thrown by the spinning blade.
m. Do not use another person as a substitute for a table extension or as additional support. Unstable support
for the workpiece can cause the blade to bind or the workpiece to shift during the cutting operation pulling you and
the helper into the spinning blade.
n. The cut-o piece must not be jammed or pressed by any means against the spinning saw blade. If
conned, i.e. using length stops, the cut-o piece could get wedged the blade and thrown violently.
o. Always use a clamp or a xture designed to properly support round material such as rods or tubing. Rods
have a tendency to roll while being cut, causing the blade to “bite” and pull the work with your hand into the blade.
p. Let the blade reach full speed before contacting the workpiece. This will reduce the risk of the workpiece

SAVE THESE INSTRUCTIONS.
Refer to them often and use them to instruct others.
If tool is loaned to someone, also loan them these instructions.
being thrown.
q. If the workpiece or blade becomes jammed, turn the miter saw o. Wait for all moving parts to stop
and disconnect the plug from the power source and/or remove the battery pack. Then work to free the
jammed material. Continued sawing with a jammed workpiece could cause loss of control or damage ti the miter
saw.
r. After nishing the cut, release switch, hold the saw down and wait for the blade to stop before removing
the cut-o piece. Reaching with your hand near the coasting blade is dangerous.
s. Hold the handle, rmly when making an incomplete cut or when releasing the switch before the saw
head is completely in the position. The breaking action of the saw may cause the saw to be suddenly pulled
downward, causing a risk of injury.
t. Saw Head lock pin is for storage and transport only. This saw should never be locked in the down position while
making cuts.
u. Do not operate saw without guards in place.
Dust created by power sanding, sawing, grinding, drilling, and other construction activities may contain chemicals
known to the state of California to cause cancer, birth defects or other reproductive harm. Some examples are:
• Lead from lead-based paints
• Crystalline silica from bricks and cement and other masonry products
• Asbestos dust
• Arsenic and chromium from chemically-treated lumber
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 dust masks that are specically designed to lter
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.

10
POWER CONNECTIONS
A separate electrical circuit should be used for your machines. This circuit should not be less than #12 wire. Before connecting the
machine to the power line make sure the switch(es) is(are) in the “OFF” position and be sure that the electric current is of the same
characteristics as indicated on the machine. All line connections should make good contact. Running on low voltage will damage the
machine.
This machine is double insulated. Double insulation is a concept in safety in electric power tools, which eliminates the need for
the usual three-wire grounded power cord. All exposed metal parts are isolated from the internal metal motor components with
protecting insulation. Double insulated tools do not need to be grounded.
NOTE: Servicing of a tool with double insulation requires extreme care and knowledge of the system and should be performed by a
qualified service technician. For service, we suggest you return the tool to the nearest authorized service center for repair. ALWAYS
use identical replacement parts when servicing.
Your machine is wired for 120 volts, 60 HZ alternating current. Before connecting the machine to the power source, make sure the
switch is in the “OFF” position.
DOUBLE INSULATION
DO NOT EXPOSE THE MACHINE TO RAIN OR OPERATE THE MACHINE IN DAMP LOCATIONS.
The double insulated system is designed to protect the user from shock resulting from a break in the tool’s internal
insulation. However, it is important to observe normal safety precautions to avoid electrical shock.
This tool has a precision-built electric motor. It should be connected to a POWER SUPPLY THAT IS 120 VOLTS, 60 HZ, AC ONLY
(NORMAL HOUSEHOLD CURRENT). DO NOT operate this tool on direct current (DC). A substantial voltage drop will cause a loss of
power and the motor will overheat. If the tool does not operate when plugged into an outlet, double-check the power supply.
To reduce the risk of electric shock, this equipment 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 fully fit 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.
When using a power tool at a considerable distance from a power source, be sure to use an extension cord that has the capacity to
handle the current the tool will draw. An undersized cord will cause a drop in line voltage, resulting in overheating and loss of power.
Use the chart to determine the minimum wire size required in an extension cord. ONLY round jacketed cords listed by Underwriter’s
Laboratories (UL) should be used.
NOTE: Before using any extension cord, inspect it for loose or
exposed wires and cut or worn insulation.

POLARIZED PLUGS
EXTENSION CORDS
KEEP the extension cord clear of the work
area. Position the cord so that it will not get caught on lumber,
tools or other obstructions while you are working with a power
tool. Failure to do so can result in serious personal injury.
Check extension cords before each use. If damaged replace
immediately. NEVER use tool with a damaged cord, since
touching the damaged area could cause electrical shock
resulting in serious injury.

CUTTING WARPED MATERIAL
See Figure 24.
When attempting to cut warped material, the CONVEX face
should be against the fence.
See Figure 25.
NEVER position a piece of warped material with the CONCAVE
face or edge against the fence. It will pinch the blade near the
completion of the cut.
To avoid a kickback and to avoid serious
personal injury, NEVER position the concave edge of bowed or
warped material against the fence.
Figure 25
• DO NOT allow familiarity with tools to make you careless. Remember that a careless fraction of a second is sucient enough to
inict serious personal injury.
• ALWAYS wear eye protection with side shields and marked to comply with ANSI Z87.1 Failure to do so could result in objects
being thrown into your eyes, resulting in possible serious personal injury.
• DO NOT use any attachments or accessories not recommended by the manufacturer of this tool. The use of attachments or
accessories not recommended can result in serious personal injury.
• Before starting any cutting operation, clamp or bolt the compound miter saw to a workbench. NEVER operate the miter saw on
the oor or in a crouched position. Failure to heed this warning can result in serious personal injury.
• To avoid serious personal injury, ALWAYS tighten the miter lock handle and bevel lock knob securely before making a cut.
Failure to do so could result in movement of the control arm or miter table while making a cut.
• To avoid serious personal injury, KEEP hands outside the no hands zone, at least 4 inches from blade. NEVER perform any
cutting operation freehand (without holding workpiece against the fence). The blade could grab the workpiece if it slips or twists.
• When using a work clamp or C-clamp to secure the workpiece, clamp workpiece on one side of the blade only. The workpiece
MUST remain free on one side of the blade to prevent the blade from binding in workpiece. The workpiece binding the blade will
cause motor stalling and kickback. This situation could cause an accident resulting in serious personal injury.
• NEVER move the workpiece or make adjustment to any cutting angle while the saw is running and the blade is rotating. Any slip
can result in contact with the blade causing serious personal injury.
• When cutting, DO NOT force the blade against the workpiece. Forcing the blade will cause a drop in motor RPM and increase
the risk of overheating the saw blade tips.
You may use this tool for the following purposes:
• Bevel cutting and compound cutting for crown moldings, etc.
• Cross cutting wood.
• Cross cutting for moldings, door casings, picture frames, etc.
NOTE: This saw is for cutting wood. The blade provided is acceptable for wood cutting ONLY.

OPERATION
• The two edges of the molding that contact the ceiling and the wall are at angles that, when added together, equal exactly 90°.
Most crown molding has a top rear angle (the section that ts at against the ceiling) of 52° and a bottom rear angle (the
section that ts at against the wall) of 38°.
• To accurately cut crown molding for a 90° inside or outside corner, lay the molding with its broad back surface at on the miter
table and against the fence.
• The angles for crown moldings must be very precise. The bevel and miter angles are interdependent; changing one angle
changes the other angle as well.
• Since it is very easy for the work piece to shift, all settings should rst be tested on scrap molding. Also most walls corners do
not have angles of exactly 90°; therefore, you will need to ne-tune your settings.
• When cutting crown molding the bevel angle should be set at 33.85°.
• The miter angle should be set at 31.62° either right or left, depending on the desired cut for the application. See the chart on
next page for correct angle settings and correct positioning of crown molding on the work table.

AUXILIARY FENCE
See Figure 36
For cutting certain workpieces, you may require a larger fence
surface area to accommodate the workpiece. The auxiliary
fence should be made using 3/4 inch thick wood. Use the
mounting holes (in bold) which are pre-drilled in the fence to
attach an auxiliary fence.
NEVER use auxiliary fence which interferes
or makes contact with saw head. ALWAYS check for clearance
between auxiliary fence and saw head before making cuts.
To make slide cuts using an auxiliary fence, a
notch MUST be cut out in the auxiliary fence prior to attaching
to saw fence.
The auxiliary fence can ONLY be used with
the 0° bevel angle. Remove the auxiliary fence before making
a bevel cut.
See Figure 37 for auxiliary fence dimensions.
1. Place auxiliary fence wood against miter saw fence. See Figure 36. The maximum height for this wood MUST NOT exceed
5.5 inch. Check to make sure auxiliary fence does make contact with saw head, check with saw head in the full DOWN and
fully RETRACTED position.
2. Mark the hole locations on the backside of the auxiliary fence board.
3. Drill the marked hole locations all the way through the auxiliary fence. Countersink the drilled holes on the front side of
your auxiliary fence board.
4. Fasten the auxiliary fence using at head screws. Secure from behind using at washers and nuts.
5. Make a full depth cut through the auxiliary fence, to create the blade slot.
6. The notch shown in Figure 37 must be cut out in order to make slide cuts using the auxiliary fence.

remove dirt, dust, oil, grease, etc.
DO NOT at any time let brake fluids,
gasoline, petroleum-based products, penetrating oils, etc.,
come in contact with plastic parts. Chemicals can damage,
weaken or destroy plastic which may result in serious personal
injury.
Electric tools used on fiberglass material, wallboard,
spackling compounds, or plaster are subject to accelerated
wear and possible premature failure because the fiberglass
chips and grindings are highly abrasive to bearings, brushes,
commutator, etc. Consequently, we DO NOT recommend
using this tool for extended work on these types of materials.
However, if you do work with any of these materials, it is
extremely important to clean the tool using compressed air.
LUBRICATION
All of the 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 lubrication
is required.
BRUSH REPLACEMENT
The motor on this saw features externally accessible brush
assemblies that should be periodically checked for wear. If the
brushes need to be replaced, see to Figure 41 and proceed as
follows:
1. Unplug the saw.
2. Failure to unplug the saw could result in
accidental starting causing serious personal injury.
3. Loosen Screws (A) and remove motor end cap (B). Using
a flathead screwdriver carefully remove the brush cap
(F18).
NOTE: Remove the cap slowly. The brush assembly is spring-
loaded and will pop out once the cap is removed.
4. Remove brush assembly (D).
5. Inspect both brushes. If either has less than 1/4 inch
length of carbon remaining, both brushes should be
replaced.
NOTE: DO NOT replace one side without replacing the other.
6. Insert both brushes into the brush tubes (E), making sure
the curvature of the brushes matches curvature of motor.
Brush assembly should move freely within the tube.
7. Carefully replace the brush cap, ensuring that it is not
cross-threaded.
8. Tighten brush cap securely. DO NOT over-tighten.
