QUICK START GUIDE
Fig. A
Make sure all accessories and the blade
are installed correctly and are tight before
operating the saw.
NOTE: The blade has been installed in the
mitre saw at the factory. Rechecking the
blade before cutting is necessary.
Use the hold-down clamp to hold the
workpiece firmly against the fence to
prevent movement towards the blade. It is
safer than using your hand and it frees both
hands to operate the mitre saw.
With the power switch OFF, bring
the saw blade down to the workpiece to see
the cutting path of the blade. Then, squeeze
trigger switch to start saw and lower blade
into workpiece with a firm downward
motion.
Hold the cutting arm in the down position.
Release trigger switch and wait for all
moving parts to stop before moving your
hands and raising the cutting arm.
A bowed workpiece (1) must be positioned
against the fence and secured with a hold-
down clamp (2) as shown before cutting.

WARNING!
To avoid mistakes that could cause serious injury, read this owner’s manual
carefully before plugging in the mitre saw.
SAFETY GUIDELINES
GENERAL SAFETY RULES
Safety is a combination of common sense, staying alert, and knowing how the mitre
saw works.
• READ and become familiar with this Owner’s Manual. LEARN the tool’s
applications, limitations, and possible hazards.
• AVOID DANGEROUS CONDITIONS. DO NOT use power tools in wet or damp areas,
and DO NOT expose them to rain. Keep work areas well lit.
• DO NOT use power tools in the presence of flammable liquids or gas.
• KEEP the work area clean, uncluttered, and well lit. DO NOT work on floor surfaces
that are slippery because of sawdust or wax.
• KEEP BYSTANDERS AT A SAFE DISTANCE FROM the work area, especially when
the tool is operating. DO NOT allow children near the tool.
• DO NOT FORCE THE TOOL. It will do the job better and safer at the rate for which
it was designed.
•
DRESS FOR SAFETY. DO NOT wear loose clothing, gloves, neckties, or jewellery
(rings, watches, etc.) when operating this tool. These items can get caught in
moving parts and draw the operator in. WEAR non-slip footwear, and tie back long
hair.
• WEAR A FACE MASK OR DUST MASK. Sawing operations produce dust.
• UNPLUG the power cord from the electrical outlet before making adjustments,
changing parts, cleaning, or performing maintenance on this tool.
• KEEP GUARDS IN PLACE AND IN WORKING ORDER.
• AVOID ACCIDENTAL START-UPS. VERIFY that the power switch is in the OFF
position before plugging in the power cord.
• REMOVE ADJUSTING TOOLS. VERIFY that all tools are removed from the mitre saw
before turning it on.

SAFETY GUIDELINES
• DO NOT LEAVE THE POWER SWITCH IN THE ON POSITION WHILE THE TOOL IS
UNATTENDED. Turn the power switch to the OFF position. DO NOT leave the tool
until it has come to a complete stop.
• DO NOT STAND ON THE TOOL. Serious injury could result if the tool tips or is
accidentally jarred. DO NOT store anything above or near the tool.
• DO NOT OVERREACH. Keep proper footing and balance at all times. Wear
oil-resistant rubber-soled footwear. Keep the floor clear of oil, scraps, and other
debris.
• MAINTAIN TOOLS PROPERLY. KEEP tools clean and in good working condition.
Follow instructions for lubricating and changing accessories.
• CHECK FOR DAMAGED PARTS. Inspect moving parts for alignment, jamming,
breakage, improper mounting, or any other condition that may affect the operation
of the tool. Any part that is damaged should be properly repaired or replaced
before use.
• MAKE THE WORKSHOP CHILDPROOF. Use padlocks and master switches, and
ALWAYS remove starter keys.
• DO NOT operate the tool while under the influence of drugs, alcohol, or medication
that may affect the ability to use the tool properly.
• WHEN SERVICING, USE ONLY IDENTICAL REPLACEMENT PARTS.
• DO NOT ALLOW ANYONE WHO HAS NOT CAREFULLY READ AND FULLY
UNDERSTOOD THIS OWNER’S MANUAL TO USE OR OPERATE THIS MITRE SAW.
ALWAYS WEAR EYE PROTECTION.
A mitre saw can propel foreign objects into the eyes, which
could cause permanent eye damage. ALWAYS wear safety
goggles (not glasses). Ordinary eyeglasses only have
impact-resistant lenses. They are NOT safety goggles.
WARNING:
Dust that is generated when cutting certain materials can be
hazardous to the health. Always operate the mitre saw in a
well-ventilated area, and provide for proper dust removal. Use a
dust collection system whenever possible.

SAFETY GUIDELINES
SPECIFIC SAFETY RULES FOR DUAL-BEVEL SLIDING MITRE SAW
• USE ONLY CROSSCUTTING SAW BLADES. When using carbide-tipped blades,
make sure they have a negative hook angle. Do not use blades with deep gullets,
because they can deflect and contact the guard.
• DO NOT operate the mitre saw until it is completely assembled and installed
according to these instructions.
• IF YOU ARE NOT thoroughly familiar with the operation of mitre saws, call the toll-
free helpline (1-800-689-9928) for further assistance.
• ALWAYS hold the work firmly against the fence and table. DO NOT perform any
operation free hand.
• KEEP HANDS out of the path of the saw blade. If the workpiece you are cutting
would cause your hands to be within 8 3/4” (22 cm) of the saw blade, the
workpiece should be clamped in place before making the cut.
• BE SURE the blade is sharp, runs freely, and is free of vibration.
• ALLOW the motor to come up to full speed before starting 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.
• BE SURE blade and collar are clean. Tighten arbour screw and clamps before
sawing.
• USE only blade collars specified for your saw.
• NEVER use blades larger or smaller in diameter than 12” (30.5 cm).
• 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 3200 RPM.
• USE the blade guards at all times.
• Do not operate saw without guards in place.
• NEVER reach around the saw blade.
• Wear respiratory and hearing protection.
• Keep hands out of path of saw blade.
• Secure tool properly to prevent unexpected movement.
