gEnErAL SAFETY rULES

WArning:

Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals 
known to cause cancer, birth defects or other reproductive harm.  Some examples of these chemicals are:

• leadfromlead-basedpaints,
• crystallinesilicafrombricksandcementandothermasonryproducts,and
• arsenicandchromiumfromchemicallytreatedlumber.

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 those dust 
masks that are specially designed to filter out microscopic particles.

DEPTH OF CUT ADJUSTMENT 

WArning:

 Be sure the machine is unplugged from the power source. Accidental saw start-up could result in 

serious personal injury.

nOTE: 

Your Miter Saw should come adjusted properly for depth of cut while using the Factory-installed blade for 

normal operation.

This is factory set and usually does not require adjusting. (This saw may not come with the necessary tools for 

the following procedure.)

WArning:

  Whenever installing a new blade, always be sure that the new blade does not contact any part of 

the machine’s metal base when the handle is completely lowered. Perform this test with the tool unplugged from the 
power source.

SQUARING THE SAW BLADE TO THE FENCE

WArning: 

Be sure that the tool is switched off and unplugged from the power source before performing any 

work on the tool. Failure to unplug the saw may result in accidental start-up, causing possible serious personal injury.

1. unplugthemitersaw.
2. Loosenthemiterlockknob(7),rotatethemitertableandmovepointertothe0°position.(FIG6)

LASER ALIGNMENT

WArning:

 Laser light – do not stare into the beam, aperture, or into a reflection from a mirror-like surface. 

WArning:

 Avoid exposure – laser light is emitted from the rear guard aperture. Use of controls or adjustments,

WArning:

 DO not disassemble the laser module. 

WArning:

 USE of controls or adjustments or performance of procedures other than those specified herein 

may result in hazardous radiation exposure. 

WArning:

 BE sure that the tool is switched off and unplugged from the power source before performing any 

work on the tool. Failure to unplug the saw may result in accidental start-up, causing possible serious personal injury.

WArning:

 Always be sure the miter saw is disconnected from the power source before making any 

adjustments or setting up prior to cutting. Failure to disconnect or unplug the machine may cause accidental starting, 
resulting in serious personal injury.

WArning:

 Always transport the miter saw in the locked down position, carrying the saw by carrying handle on 

the cutting arm. DO nOT lift or carry the miter saw using the switch handle, doing so may cause misalignment of miter 
and bevel settings.

STARTING AND STOPPING THE MITER SAW

To start the miter saw,firmlygraspthesaw’stophandleanddepresstheswitchtrigger.
To stop the miter saw,completelyreleasetheswitchtrigger.
Thismitersawisequippedwithanautomaticelectricbladebrake.Whentheswitchtriggerisreleased,theelectricbrakeisactivatedandstopsthesaw

WArning: 

After completing a cut, release the switch trigger to activate the electric blade brake. Keep the 

cutting head down until the blade comes to a complete stop before raising the cutting head to the upward or starting 
position. A rotating saw blade can be dangerous. 

WArning:

 The torque resulting from electric blade brake activation may loosen the arbor bolt. Occasionally 

check the arbor bolt and tighten if necessary.

WArning:

 Keep your hands outside the “Hazard Zone” and out of the path of the saw blade. Use the supplied 

work clamp or other clamping means to secure the work piece in place before making a cut with the miter saw. 

WArning:

Always be sure the miter saw is disconnected from the power source before making any 

adjustments or during set-up prior to cutting. Failure to disconnect or unplug the machine may cause accidental 
starting, resulting in serious personal injury.

TYPICAL COMPOUND MITER SAW OPERATIONS
 

WArning:

  Always be sure the miter saw is disconnected from the power source before making any 

adjustments or during set-up prior to cutting. Failure to disconnect or unplug the machine may cause accidental 
starting, resulting in serious personal injury.
 

WArning:

 Be sure the miter saw is securely bolted down or clamped to a workbench or appropriate work 

surface before performing any cutting operations. Failure to do so may result in loss of machine control and/or 
result in personal injury. 

WArning:

 if securely holding the work piece causes your hand to be in the machine’s “Hazard Zone”, clamp 

the work piece in place and move your hand(s) to a safe position before making the cut.

SAW BLADE INSTALLATION OR REMOVAL 

WArning:

 Be sure that the tool is switched off and unplugged from the power source before performing any 

work on the tool. 

WArning:

 Use only 10” diameter saw blades that have 5/8” diameter arbor holes and are rated for speeds 

equal to or greater then the nameplate rated rPM of this miter saw. 

WArning:

 Use only blades designed for cross-cutting operations. 

WArning: 

Do not use thin kerf blades with deep gullets which may deflect and contact the blade guards or 

produce poor quality cuts in the work piece.

To remove the blade

1. unplugthetoolfromthepowersource.
