RULES FOR SAFE OPERATION
KNOW THE TOOL
To operate this tool safely, carefully read this operating manual and all the labels
affixed to the Compound Mitre Saw before using it, and follow all instructions
contained therein. Retain this manual for future reference.
IMPORTANT
This tool should only be serviced by a qualified service technician.
READ ALL INSTRUCTIONS THOROUGHLY
SAFETY PRECAUTIONS FOR LASERS
This Mitre Saw has a built-in laser
light. The laser is ClassIIlA and emits
output power of a maximum 2.5mW
and 635-650nm wavelengths. These
lasers do not normally present an optical
hazard. However, DO NOT stare at the
beam, as this can cause flash blindness.
CAUTION: The following label is on the
tool. It indicates the location from which
the saw emits the laser light. BE AWARE of the laser-light location when using.
Always make sure that any bystanders in the vicinity of use are made aware of
the dangers of looking directly into the laser.
• Do not remove or deface any product labels. Removing product labels
increases the risk of exposure to laser radiation.
• The laser beam can be harmful to the eyes. Always avoid direct
eye exposure.
• Do not look directly into the laser-beam-output aperture during operation.
• Do not project the laser beam directly into the eyes of others.
• Turn the laser on only when making cuts. The laser on the Mitre Saw
is not a toy. Always keep it out of the reach of children. The laser light
emitted from this device should never be directed toward any person for
any reason.
• Be sure that the laser beam is aimed at a work piece (such as wood or a
rough-coated surface) that does not have a reflective surface.
• Do not use on materials, such as sheet steel, that have shiny, reflective
surfaces. The reflective surface could reflect the beam back at the
operator. Be aware that laser light reflected off of a mirror or any other
reflective surfaces can also be dangerous.
• Always turn the laser beam off when it is not in use. Leaving the tool on
increases the risk of someone inadvertently staring into the laser’s beam.

4
CAUTION: Always follow the instructions contained in this manual when us-
ing this laser. Use of this feature in any manner other than which is directed in
this manual may result in a hazardous radiation exposure.
• Always wear laser-protective eyewear when working on or near reflective
surfaces.
GENERAL SAFETY PRECAUTIONS
Read and become familiar with the entire Operating Manual.
Learn the tool’s application, limitations, and possible hazards.
Keep the guard in place and in working order.
Remove all adjusting tools before turning tools on. Form the habit of checking
to see that keys and adjusting wrenches are removed from the tool before
turning the tool ON.
Keep the work area clean. Cluttered areas and benches invite accidents.
Do not use the tool in wet locations. Do not use power tools in damp locations
or expose them to rain or snow.
Keep the work area well lit.
Keep children away. All visitors & bystanders should be kept a safe distance
from the work area.
Make the workshop childproof with padlocks, master switches, or by removing
starter keys.
Do not force the tool. The tool will do the job better and more safely at its
designed rate.
Only use the correct tool. Do not force the tool or an attachment to do a job
that it was not designed to perform.
Use proper extension cords. Make sure that extension cords are in good
condition. When using an extension cord, be sure to use a cord heavy
enough to carry the drawn current needed by the Compound Mitre Saw. An
undersized cord will result in a drop in line voltage and in loss of power, which
will cause the tool to overheat. The table on Page 5 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.
Wear proper apparel. Do not wear loose clothing, gloves, neckties, rings,
bracelets, or other jewellery that may get caught in moving parts. Non-
slip footwear is recommended. Wear a protective hair covering to contain
long hair
Wear a facemask or a dust mask. Sawing operations produce dust.
Secure the work. Use clamps or a vise to hold the work; it is safer than using
the hand/body and it allows both hands to operate the Compound Mitre Saw.

5
Disconnect tools before servicing the tool and when changing accessories,
such as blades, bits, and cutters.
Reduce the risk of the tool unintentionally starting. Make sure that the switch
is in the OFF position before plugging in the tool.
Only use recommended accessories. Consult this Operating Manual for
recommended accessories. The use of improper accessories may cause risk
of injury to the operator or to others.
Never stand on the tool. Serious injury could occur if the tool is tipped or if the
cutting tool is unintentionally contacted.
WARNING : The operation of any tool can result in foreign objects be-
ing propelled into the eyes, which could result in severe eye damage. When
operating a power tool, always wear safety goggles or safety glasses with side
shields, or a full-face shield, if necessary.
Check for damaged parts. Before further use of the tool, a guard or other part
that is damaged should be carefully checked to determine that 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 the operation of the tool. A guard or other part that
is damaged should be properly repaired or replaced.
Never leave the tool unattended while the power is “on.” Turn the power
“off.” Do not leave the tool until the blade has come to a complete stop and the
Mitre Saw has been unplugged.
Do not over-reach. Keep proper footing and balance at all times.
Maintain tools with care. Keep tools sharp and clean for optimum performance.
Follow instructions for lubricating and changing accessories.
WARNING : Do not attempt to operate this tool until having thoroughly read
all instructions, safety rules, and warnings. Failure to comply can result in fire,
electric shock, or serious personal injury. Retain the Operating Manual for fu-
ture reference and review it frequently.
WARNING : Dust generated from certain materials can be hazardous to one’s
health. Always operate the saw in a well-ventilated area, and provide for proper
dust removal.
ELECTRICAL SAFETY
Ground instruction: In the event of a malfunction or breakdown, grounding
provides a path of least resistance for electric current to reduce the risk of
electric shock. This tool is equipped with an electric cord having an equipment-
grounding conductor and a grounding plug. The plug must be plugged into a
matching outlet that is properly installed and grounded in accordance with all
local codes and ordinances.

6
Do not modify the plug provided. If it will
not fit the outlet, have a proper outlet
installed by a qualified electrician.
Use only 3-wire extension cords that
have 3-prong grounding plugs and 3-pole
receptacles that accept the tool’s plug.
Permanently connected tools: This
tool should be connected to a grounded
metal permanent wiring system or to a
system having an equipment-grounding
conductor.
GUIDELINES FOR EXTENSION CORDS
Use a proper extension cord. Make sure that extension cords are in good
condition. When using an extension cord, be sure to use a cord heavy enough
to carry the drawn current needed by the Compound Mitre Saw. 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 the 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 extension cords are properly wired and in good condition. Always
replace a damaged extension cord or have it repaired by a qualified person
before using it. Protect extension cords from sharp objects, excessive heat, and
damp or wet areas.
Use a separate electrical circuit for power tools. This circuit must not be less
than #6 wire and should be protected with a 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.

ed. If not sure, have a licensed electrician check the outlet.
WARNING : To avoid electrical hazards, fire hazards, or damage to the tool,
use proper circuit protection.
SPECIFIC SAFETY RULES
Use only crosscutting saw blades. When using the miter saw to cut nonferrous
metal , make sure that the blade has a negative hook angle.
IMPORTANT: Do not use thin-kerf blades. Thin-kerf blades can deflect and
contact the guard, which can cause possible injury to the operator.
Do not operate the Mitre Saw until it is completely assembled and installed
according to these instructions.
If not thoroughly familiar with the operation of Mitre Saws, seek guidance from
a supervisor, instructor, or other qualified person.
Always hold the work firmly against the fence and table. Do not perform any
operation free hand; use a clamp or vise whenever possible
Keep hands out of the path of the saw blade. If the work piece causes the hands
to be within the “no hands” zone (3’’ (7.6 cm) from the blade), the work piece
should be clamped in place before making the cut.
Be sure that 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’s air slots clean and free of chips or dust.
Always make sure that all adjusting knobs are tightened before cutting, even if
the table is positioned in one of the positive stops.
Be sure that both the blade and the flange are clean and the arbour bolt is
tightened securely.
Use only blade flanges specified for this saw
Never use blades larger or smaller in diameter than 10 inches (25.4 cm).
Never apply lubricants to the blade while it is running.
Always check the blade for cracks or damage before operation. Replace a
cracked or damaged blade before further use.
Never use blades recommended for operation at less than 5000 RPM.
Use the blade guards at all times.
Always keep the blade guards in place.
Never reach around the saw blade.
Make sure that the blade is not contacting the work piece before the ON/OFF
switch is turned ON.

8
IMPORTANT: After completing the cut, release the power switch and wait for
the blade to stop before returning the saw to the raised position.
Make sure that the blade has come to a complete stop before removing or
securing the work piece, changing the work-piece angle, or changing the angle
of the blade.
Never cut metals or masonry products with this tool. This Mitre Saw is designed
for use on wood and wood-like products.
Never cut small pieces. Keep hands outside the no-hands zone: at least 3” (7.6
cm) from the blade.
Provide adequate support to the sides of the mitre table for long work pieces.
Never use the Mitre 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 and unplug the tool before servicing or adjusting the tool.
Disconnect the saw from the power source and clean the tool when finished
using it.
Make sure that the work area is clean before leaving the tool.
Should any part of this Compound Mitre Saw be missing, damaged, or fail in
any way, or should any electrical component fail to perform properly, shut off
the power switch and remove the plug from the power-supply outlet. Replace
missing, damaged, or failed parts before resuming operation.
