SAFETY GUIDELINES SAFETY GUIDELINES
• Never stand on tool. Serious injury could occur if the tool is tipped or if something unintentionally
comes into contact with the cutting tool.
• Check damaged parts. Before further use of the tool, a guard or other part that is damaged should
be carefully checked to determine whether it will operate properly and perform its intended function
- check for alignment of moving parts, binding of moving parts, breakage of parts, mounting, and any
other conditions that may affect its operation. A guard or other part that is damaged should be properly
repaired or replaced.
• Direction of feed. Feed work into a blade or cutter against the direction of rotation of the blade or
cutter only.
• Never leave tool running unattended. Turn power off. Don’t leave tool until it comes to a complete
stop.
DOUBLE-INSULATED TOOLS
• When servicing, use only identical replacement parts.
• Polarized Plugs: 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 fit fully into 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.
ELECTRICAL SAFETY
• To reduce the risk of electric shock, double-insulated tools are equipped with a polarized
plug (one blade is wider than the other). This plug will fit into a polarized outlet only one way. If
the plug does not fit into the outlet properly, reverse the plug. If it still does
not fit, contact a qualified electrician to install a polarized outlet. Do not
change the plug in any way.
• Double insulation eliminates the need for the three-wire grounded
power cord and grounded power supply system. This compound
mitre saw is a double-insulated tool.
• Before plugging in the tool, BE SURE that the outlet voltage
supplied is within the voltage marked on the tool’s data plate. DO NOT use “AC only” rated
tools with a DC power supply.
• Avoid body contact with grounded surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of electric shock if your body is grounded.
• DO NOT expose power tools to rain or wet conditions and do not use power tools in wet
or damp locations. Water entering a power tool will increase the risk of electric shock. This tool is
intended for indoor use only.
• If operating a power tool in damp locations is unavoidable, ALWAYS USE a power supply for
your tool that is protected by a Ground Fault Circuit Interrupter. ALWAYS WEAR electrician’s
rubber gloves and footwear in damp conditions.
• Inspect tool cords for damage. Have damaged tool cords repaired by a qualied person. BE
SURE to stay constantly aware of the cord location, and keep it well away from the moving blade.
• 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 and moving parts. Replace damaged cords
immediately. Damaged cords increase the risk of electric shock.
• Use 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 overheating. The
following table 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.

SAFETY GUIDELINES SAFETY GUIDELINES
• Be sure to turn the tool off and wait for the saw blade to stop before moving the workpiece or
changing settings.
• Be sure that the power is disconnected before changing the blade or servicing the saw.
• Do not expose to rain or use in a damp location.
• When servicing, use only identical replacement parts.
• Never reach around the saw blade.
• Do not perform any operation freehand. Always place the workpiece to be cut on the mitre saw
table and position it firmly against the fence as a backstop. Always use the fence.
• Always keep hands out of the path of the saw blade. Do not reach under the material being cut
or into the blade’s cutting path with your fingers or hand for any reason.
• To reduce the risk of injury, return the cutting head to the full rear position after each crosscut
operation.
• Always make sure that the mitre table and head assembly (bevel function) are locked in
position before operating your saw. Lock the mitre table by securely tightening the mitre locking
handle. Lock the head assembly (bevel function) by securely tightening the bevel locking knob.
• Be sure the blade path is free of nails. Always carefully inspect lumber and remove all nails
BEFORE cutting.
• Always be sure the blade clears the workpiece. Never start the saw with the blade touching the
workpiece. Always allow the motor to come up to full speed before starting a cut.
• Support long workpieces when cutting to minimize the risk of blade pinching or kickback.
The saw may slip, walk or slide while cutting long or heavy boards.
• Never use a length-stop on the free end of a clamped workpiece. Never hold onto or bind the
free end of the workpiece in any operation. If a clamp and length-stop are used together, they must
both be installed on the same side of the saw table to prevent the saw from catching the loose end and
kicking up.
• Never cut more than one piece at a time. Do not stack more than one workpiece on the worktable
at a time.
• Avoid awkward operations and hand positions where a sudden slip could cause your hand
to hit the blade. Always make sure you have good balance. Never operate your saw on the floor or in
a crouched position.
• Only use the correct blades. Use the correct blade size, style and cutting speed for the material and
the type of cut. Do not use blades with incorrect size holes. NEVER use blade washers or blade bolts
that are defective or incorrect. The maximum blade capacity for this saw is 10” (25.4 cm).
• Always keep blades clean, sharp and properly set. Sharp blades minimize stalling and kickback.
• Do not use dull or damaged blades. Bent blades can break easily or cause kickback.
• Never hold a workpiece by hand if it is too small to be clamped. Always keep your hands clear
of the “no hands” zone.
• Never apply lubricants to the blade when it is running.
• Never use solvents to clean plastic parts. Solvents could dissolve or otherwise damage the
material.
• Do not turn the motor switch on and off rapidly. This could cause the blade to loosen, which
could create a hazard. Should this ever occur, stand clear and allow the saw blade to come to a
complete stop. Disconnect the saw from the power source and tighten the blade bolt securely.
• Never leave the saw unattended while it is connected to a power supply.
• Keep the motor air slots clean and free of chips or dust. To avoid motor damage, the motor
should be blown out or vacuumed frequently. This keeps sawdust from interfering with the motor
ventilation.
• Never lift this tool by gripping the switch handle or by the mitre fence. This may cause
misalignment. Always lock the head assembly in the “Down” position and carry the saw by holding the
base or lift it using the carrying handle/support bracket.
ADDITIONAL RULES FOR SAFE OPERATION

on the bevel scale (2).
• The blade can be positioned at any angle, from a
90° straight cut (0° on the scale) to a 45° left bevel.
Tighten the bevel lock knob to lock the cutting head in
position. Positive stops are provided at 0° and 45°.
COMPOUND CUT (Fig. 17)
A compound cut is the combination of a mitre and a bevel
cut simultaneously.
• Loosen the bevel lock knob (1) and position the
cutting head at the desired bevel position. Lock the
bevel lock knob.
• Loosen the mitre handle (2). Push down the positive
stop locking lever (3) and position the table at the
desired angle. Release the positive stop locking lever
and lock the mitre handle.
OPERATING INSTRUCTIONS
IMPORTANT:
Always tighten the mitre table lock handle before performing every cutting operation.

CUTTING WARPED MATERIAL (Fig. 18)
When cutting warped material, be sure that the convex side
is against the fence. If the workpiece is placed with the
concave side facing the fence, it will pinch the blade near
the completion of the cutting.
AUXILIARY WOOD FENCE (Fig. 19)
When making multiple or repetitive cuts that result in
cut-off pieces of 1” (2.5 cm) or less, it is possible for the
saw blade to catch the cut-off piece and throw it out of the
saw or into the blade guard and housing, possibly causing
damage or injury. To minimize this, an auxiliary wood fence
can be mounted to your saw. Holes are provided in the
saw fence to attach an auxiliary wood fence (this provides
additional depth of cut). This fence should be constructed
of straight auxiliary wood approximately 3/4” (1.9 cm) thick
by 1 1/2” (3.8 cm) high by 17” (43.2 cm) long. Attach the
wood fence securely and make a full depth cut to make a
blade slot. Check for interference between the wood fence
and the lower blade guard. Adjust if necessary.
CUTTING BASE MOULDING (Fig. 20)
Base mouldings and many other mouldings can be cut on
a compound mitre saw. The setup of the saw depends
on moulding characteristics and applications, as shown.
Perform practice cuts on scrap material to achieve best
results:
• Always make sure mouldings rest firmly against
the fence and table. Use hold-down or C-clamps,
whenever possible, and place tape on the area being
clamped to avoid marks.
OPERATING INSTRUCTIONS
CAUTION!
Always use a work clamp to maintain control and reduce the risk of workpiece damage and
personal injury.
WARNING!
DO NOT USE A DADO BLADE, use only the standard saw blade for this operation.

• Reduce splintering by taping the cut area prior to making cut. Mark cut line directly on the tape.
• Splintering typically happens due to wrong blade application and thinness of the material.
CUTTING CROWN MOULDING (Fig. 21, 22)
Your compound mitre saw is suited for the difcult task of
cutting crown moulding. To t properly, crown moulding
must be compound-mitreed with extreme accuracy. The
two surfaces on a piece of crown moulding that t at
against the ceiling and wall are at angles that, when added
together, equal exactly 90°.
Most crown moulding 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°.
In order to accurately cut crown moulding for a 90° inside
or outside corner, lay the moulding with its broad back
surface at on the saw table. When setting the bevel and
mitre angles for compound mitres, remember the settings
are interdependent; changing one changes the other, as
well.
OPERATING INSTRUCTIONS
NOTE:
Always perform a dry run cut so you can determine if the operation being attempted is possible before
power is applied to the saw.

SAWDUST
Periodically, sawdust will accumulate under the table and base. This could cause difculty in the movement
of the table when setting up a mitre cut. Frequently blow out or vacuum up the sawdust.
LOWER BLADE GUARD
Do not use the saw without the lower blade guard.
The lower blade guard is attached to the saw for your protection. Should the lower guard become damaged,
do not use the saw until the damaged guard has been replaced. Check regularly to make sure the lower
guard is working properly. Clean the lower guard of any dust or buildup with a damp cloth.
REPLACING CARBON BRUSHES (Fig. 23)
Replace both carbon brushes when either has less than
1/4” (0.6 cm) length of carbon remaining, or if the spring or
wire is damaged or burned. To inspect or replace brushes,
rst unplug the saw. Remove the two screws on the back
cover of the motor and take the cover off. Move the coil
spring which press on the carbon brush to other side to
free the carbon brush. Pull out the brush and the wire
which connect to the holder. Replace it for a new carbon
brush. When replace for the other side. To reassemble,
reverse the procedure. Tighten two screws on the back
cover.
MAINTENANCE
WARNING!
• To avoid re or toxic reaction, never use gasoline, naphtha acetone, lacquer thinner or similar
highly volatile solvents to clean the mitre saw.
• To avoid injury from unexpected starting or electrical shock, unplug the power cord before
working on the saw.
• For your safety, this saw is double-insulated. To avoid electrical shock, re or injury, use
only parts identical to those identied in the parts list. Reassemble exactly to avoid electrical
shock.
CAUTION!
If blowing sawdust, wear proper eye protection to keep debris from blowing into eyes.
CAUTION!
• Do not use solvents on the guard. They could make the plastic cloudy and brittle.
• When cleaning the lower guard, unplug the saw to avoid unexpected start-up.
NOTE:
To reinstall the same brushes, first make sure the brushes go back in the way they came out.

model no. 055-6762-0 | contact us 1-800-689-9928
This will avoid a break-in period that reduces motor
performance and increases wear.
LUBRICATION (Fig. 24)
All the motor bearings in this tool are lubricated with a
sufcient amount of high-grade lubricant for the life of
the unit under normal operating conditions; therefore, no
further lubrication is required.
Lubricate the following as necessary:
Chop pivot: Apply light machine oil to points indicated in
illustration.
Central pivot of plastic guard: Use light household oil (sewing machine oil) on metal-to-metal or
metal-to-plastic guard contact areas as required for smooth, quiet operation. Avoid excessive oil as sawdust
will cling to it.
