delay fuse or circuit breaker. Using the wrong size fuse could damage the motor.
3. Replace a worn, cut or damaged power cord.
ITEM 70712 OPERATOR’S MANUAL 9
ELECTRICAL INSTRUCTIONS
Grounding Instructions
1. IN THE EVENT OF A MALFUNCTION OR BREAKDOWN, grounding provides the path
of least resistance for electric current and reduces the risk of electric shock. This
tool/equipment is equipped with an electric cord that has 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.
2. DO NOT MODIFY THE PLUG PROVIDED. If it will not fit the outlet, have the proper
outlet installed by an electrician.
3. IMPROPER CONNECTION of the equipment grounding conductor can result in electric
shock. The conductor with the green insulation (with or without yellow stripes) is the
equipment grounding conductor. If repair or replacement of the electric cord or plug is
necessary, DO NOT connect the equipment grounding conductor to a live terminal. CHECK
with a licensed electrician or service personnel if you do not completely understand the
grounding instructions, or if you are not sure if the tool/equipment is properly grounded.

1. Tools/equipment with three wire grounding plugs (Fig. 1, A) are intended for use on a circuit
that has an outlet that looks like the one illustrated (Fig. 1, B).
2. A temporary adapter (Fig. 1, D) may be used to connect this plug to a 2-pole receptacle (Fig.
1, C) if a properly grounded outlet is not available.
3. The temporary adapter should be used only until a properly grounded outlet can be installed
by a qualified electrician.
4. The green colored rigid ear, lug, etc. extending from the adapter must be connected to a
permanent ground such as a properly grounded outlet box (Fig. 1, C).
Extension Cord Guidelines
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 table below shows the
correct size to be used according to cord length and nameplate ampere rating. If in doubt, use the
next heavier gauge. The smaller the gauge number, the heavier the cord.
Minimum Gauge for Extension Cords (AWG)
(When using 120 V only)
ITEM 70712 OPERATOR’S MANUAL 11
1. Be sure your extension cord is properly wired and in good condition. Always replace a
damaged extension cord or have it repaired by a qualified person before using it.
2. Protect your extension cords from sharp objects, excessive heat and damp or wet areas.
3. Use a separate electrical circuit for your tools. This circuit must not be less than a #12 wire
and should be protected with a 20 Amp time delayed fuse.
4. Before connecting the motor 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.
WARNING: This tool/equipment must be grounded while in use to protect the operator
from electrical shock.
ITEM 70712 OPERATOR’S MANUAL 12
COMPONENTS
ASSEMBLY INSTRUCTIONS
Extension Supports Attachment
Insert the ends of the Extension Supports into the holes in the sides of the base. Tighten the
Screws to hold the Extensions in place. The upper edge of the Extensions will be level with the
surface of the saw. This provides a wider base for the work piece to rest on.
Attach the Dust Collection Bag
The Dust Collection Bag slips over the Dust Outlet behind the Blade Housing Assembly.
Sawdust created by cutting is captured in the bag.
ITEM 70712 OPERATOR’S MANUAL 13
Note: the saw is shipped with the motor locked in the down position. To release the saw for
use, push the handle downward with your left hand as if you were cutting a piece of wood.
While holding the handle down, reach back to the handle latch (release knob) with your
right hand and pull it out.
Saw Mounting
The Miter Saw must be mounted on a support before use. This may be a commercially available
support or homemade saw table. There are bolt holes provided in each of the four legs of the
base. These legs should be firmly mounted using bolts (not included) to your saw stand or saw
table (not included). This will help prevent tipping or movement of the saw, preventing injury.
Also, the use of a saw table will make it easier to efficiently handle work pieces and make more
accurate cuts.
OPERATION INSTRUCTIONS
1. Designate a work area that is clean and well lit. The work area must not allow children or
pets access to prevent injury and operator distraction.
2. Route the power cord along a safe route to reach the work area without creating a tripping
hazard or exposing the power cord to possible damage. The power cord must reach the work
area with enough extra length to allow free movement while working.
3. Use a saw table, saw stand or other means to support the work piece. The Miter Saw must be
mounted in such a way that the surface is level to the ground, and supports used must provide
a surface on the same level as the saw table. If the work surface and any work pieces
supports are not level, and on the same level, unwanted bevel angles will appear in the cuts
resulting in poor joinery.
4. Work pieces may be secured to the saw table using the Hold Down Clamp or other clamping
devices (not included). Securing the work piece will provide safety by preventing kickback
and by eliminating the need to hold work pieces near the blade by hand. Clamping the work
piece will also improve cutting accuracy by preventing the work piece from moving during
the cutting operation. Note: use only ONE hold down clamp.
5. When using this saw, work pieces are often quite long. Allow room on both the left and right
sides of saw for extended work pieces.
6. When the Handle is lowered, the Blade Guard raises automatically. When the Handle is
raised the Blade Guard returns to its safety position. Keep hands clear of the Blade when the
Handle is lowered. Never interfere with the proper movement of the Blade Guard.
7. There are locking mechanisms for the miter angle. Unlock the Table to set the miter angle,
then re-lock it before making the cut.
8. To rotate the Table, loosen the Miter Lock Handle, rotate the Table to the desired angle, then
tighten the Miter Lock Handle. Notches are machined into the Base of the tool which will
ITEM 70712 OPERATOR’S MANUAL 14
lock the Table into several often used miter angles. These angles are 0º (centered), 5º, 10º,
15º, 20º, 25º, 30º, 35º, 40º and 45º left and right.
9. To make a bevel cut, release the Bevel Lock Lever, rotate the Blade Assembly to the desired
bevel angle, then lock the Blade Assembly in place using the Bevel Lock Lever. For making
bevel cuts see page 16.
10. This saw is provided with a Kerf Board. The Kerf Board helps to prevent tear-out on the
bottom side of the work piece. The Kerf Board is factory adjusted prior to shipment of this
tool so the blade does not contact the Kerf Board during normal operation, including bevel
cuts. Adjustment of the Kerf Board and techniques to prevent tear-out are on page 16.
11. Before starting work, check the accuracy of the Guide Fence, miter angle and bevel angle.
See pages 16 and 17 for checking and adjusting these angles.
12. It is very important that the work piece be properly supported before making a cut. The
material must be level on the Table. The material must be supported on both ends. Using the
Work Piece Extension Supports is discussed below.
Work Piece Extension Supports Use
1. The Work Piece Extension Supports are inserted into each side of the Table, and locked in
place with thumb screws.
2. When properly installed, the upper face of the work piece extension supports are level with
the Table, and provide a wider support surface for the work piece.
3. Always support the work piece to be level with the Table, and so that after the cut is made
the cut off pieces will not fall. You may need to use saw horses or other supports (not
included) to support the work piece.
4. If the work piece is not level, you will make an unintentional bevel cut in the material. If the
work piece is not supported, it will bind the blade and may cause the material to kickback,
potentially causing injury.
Miter Angle Adjustment
1. A miter cut is one that is at an angle across the horizontal surface of the material. You will
commonly make 45º miter cuts to join two pieces in a right angle corner. A 30º cut is often
used for a scarf joint or to make a chamfered end.
2. To make a miter cut, loosen the Miter Lock Handle by turning it approximately 1/4 turn
counterclockwise. Move the Table to the desired angle. The Miter Angle Indicator will
indicate the selected angle. The Table will lock into place at often used miter angles,
including 0º, 5º, 10º, 15º, 20º, 25º, 30º, 35º, 40º and 45º both left and right sides.
3. Tighten the Lock Handle to the lock the Table.
4. With the Table adjusted to the desired angle, place the work piece flush against the Guide
Fence, secure it with the Hold Down Clamp and make the cut.
ITEM 70712 OPERATOR’S MANUAL 15
Bevel Angle Adjustment
1. A bevel cut is one that is at an angle to the vertical plane of the material.
2. Bevel cuts can be used to miter relatively wide and thin material. Bevel cuts can be used in
combination with a miter cut to form a compound angle. Compound angle cuts are often used
in crown moldings, picture frames and similar trim materials.
3. To set the bevel angle, loosen the Bevel Lock Handle at the rear of the saw. To do this, press
in the Lock Button and rotate the Handle 1/2 turn counterclockwise. Move the Blade
Assembly left to the desired angle. You can read the angle on the Bevel Angle Indicator.
Lock the Blade Assembly into position by pressing in the Lock Button and rotating the Bevel
Lock Handle clockwise. Tighten firmly but not over-tight.
4. Make a sample cut in a piece of scrap and check to be sure the bevel angle is correct. If it is
not, correct the angle before cutting your work piece.
Depth Stop Use
1. If you want to make a Kerfing or rabbet cut which does not cut through the work piece, you
can use the Depth Stop Screw to control the depth of the cut.
2. To limit Blade Assembly travel, turn the Depth Stop Screw clockwise. The further you screw
down the Depth Stop Screw, the shallower the cut will be.
3. After the desired cut has been made, return the Depth Stop Screw to its open position by
turning it counterclockwise.

6. Check that the edge of the square and the Saw Blade are parallel along the entire length of
the square's edge.
7. If the front or back portion of the blade angles away from
the squarer's edge, adjusting the Guide Fence is necessary.
8. Using the Allen wrench, loosen the two hex bolts (Fig. 3)
that secure the Guide Fence to the saw's stationary table.
9. While holding one leg of the square against the Guide
Fence, slowly move the Guide Fence to the left or right
until the Saw Blade is parallel with square's other leg.
10. Carefully tighten the two hex bolts and recheck the blade
alignment as in steps 5 and 6.
0º and 45º Bevel Stop Adjustments
NOTE: This is factory set and usually does not require adjusting. (This saw may not come with

points. The edge of the square and blade should be parallel; however, if the top or bottom of
the blade angles away from the square's edge, an adjustment is needed.
6. Using a wrench, loosen the Lock Nut (securing the positive bevel stop adjustment bolt in
place). The 0º bevel adjustment bolt (Fig. 5) is
located on the rear right side of the Miter Table.
7. Use another wrench to turn the adjustment
screw and so that the blade is in alignment with
the square.
8. Retighten the bevel adjustment lock nut.
Retighten the Bevel Lock Handle. Recheck the
blade to table alignment as in steps 4 and 5.
Making a Cut
1. Observe all safety and planning items discussed in this manual. Detailed instructions on each
of the following steps are discussed in this manual. Do not make any cuts until you have read
this entire manual and are familiar with the operation of this tool.
2. Release the Locking Pin to allow the Blade Assembly to come up. Check to be sure the Table
is fixed in place at the desired miter angle.
3. Blow any sawdust or debris away from the Guide Fence. Place the work piece against the
Guide Fence.
4. Make any necessary miter or bevel adjustments.
5. Align the marked location of the cut on the work piece with the Saw Blade. Be aware that the
Saw Blade will remove material from the cut equal to the width of the blade. This is the
“Kerf”. To prevent your work piece from being cut too short, align the edge of the blade with
your measured mark, keeping the Kerf on the waste side of the cut.
6. Hold the work piece in place using the Hold Down Clamp. Never use more than one hold
down clamp. Ensure that the work piece is level and supported securely, using saw horses or
supports if necessary.
7. Grip the Saw Handle and squeeze the Trigger to start the Blade turning.
8. Pressing down lightly, move the Blade smoothly across the work piece to cut it. With narrow
material, you can press straight down “chopping” the material. With wider material you must
move the blade across the material to cut it. Do not bear down on the material, use light
downward pressure. If the material binds the blade, release the trigger. Keep your hands and
fingers away from the blade.
ITEM 70712 OPERATOR’S MANUAL 18
9. When the cut is completed, raise the Blade Assembly, wait for the blade to stop turning,
release the Hold Down Clamp and remove the work piece from the saw.
Avoid Injury from Jams, Sips or Thrown Pieces
1. Use the correct 12" blade for the material and type of cut. Do not cut materials that may
shatter, grab the blade or cause other danger.
2. Only use a blade that is sharp and in good condition. Check alignment of the blade after it is
installed. Unplug the saw and carefully spin the blade using your hand. The blade should not
contact any components of the saw. If so, correct the problem before operating the saw.
3. Be sure the blade and blade flanges are clean.
4. Make sure the blade flanges are properly installed.
5. Be sure the arbor bolt and washer are properly installed and tightened.
6. Ensure all clamps and locks are tight. Verify there is no excessive play in any parts.
7. Allow the blade to reach full speed before cutting.
Do Not Cut Freehand
1. The work piece should be tight against the Guide Fence. Verify the work piece will not rock
or twist when it’s being cut. The area between the work piece and the saw must be free from
debris.
2. Make sure there is no gap between the work piece, Guide Fence and base of the saw. A gap
could allow the work piece to move when it’s being cut.
3. Use clamps, fixtures or other devices to hold an unstable work piece.
4. Do not cut more than one work piece at a time.
5. Allow room so the cut-off work piece can move after it’s cut. It could create a hazard by
becoming wedged against the blade.
ITEM 70712 OPERATOR’S MANUAL 19
Cutting Odd Shapes, Oversize or Small Pieces
1. Plan your work so an odd shaped work piece cannot slip or pinch the blade. When cutting
material like molding, it must lie flat or be held by a fixture. Do not allow the material to
rock, twist or slip.
2. Secure sagging work pieces with sawhorses, tables or other additional supports.
3. Do not cut small work pieces that you must hold closer than 4 inches from the blade.
4. Properly support round material when cutting. Dowel rods and tubing have a tendency to roll
while being cut. This could allow the blade to “bite” into the material causing a hazardous
condition. Hold round material in place using clamps or other fixtures.
5. Inspect the work piece for nails or other foreign objects before it is cut.
6. Do not allow anyone to stand behind the saw or close to the work piece where debris can be
thrown.
7. Operate your saw in a clear, safe environment.
8. Avoid contact with the rotating blade. Do not wear gloves, loose clothing or jewelry. Tie
back long hair and roll long sleeves above the elbow.
9. Unplug the power cord from the electrical outlet to avoid injury from accidental starting of
your Miter Saw. Make sure the power cord is unplugged during blade installation,
performing maintenance or making adjustments.
10. Avoid electrical shock. Do not touch the metal blades on the power cord plug when removing
or installing the plug into an electrical outlet.
11. Prevent fire hazards. Do not operate the saw near flammable liquids, vapors or gases.
12. To avoid injury from unexpected saw movement when operating your Miter Saw, use the
saw on a firm level surface with adequate space for handling and supporting the work piece.
Be sure the saw cannot move when operated. Secure the saw to a workbench or table with
wood screws, or bolts, washers and nuts.
13. To move your Miter Saw, unplug the power cord from the electrical outlet. Lock the Handle
in the down position using the Handle Latch.
14. Avoid back injuries. Obtain help when it is necessary to raise the saw more than 10 inches.
Bend your knees when lifting the saw.
15. Carry your saw by the carrying Handle or base. Do not carry your saw by the power cord or
the trigger handle. Carrying the saw by the power cord could cause damage to the insulation
or the wire connections resulting in electric shock or fire.
16. Do not make a careless error. Just because you operate the saw frequently, a neglectful
moment can cause a severe injury.
17. Do not lubricate the blade while your Miter Saw is running.
ITEM 70712 OPERATOR’S MANUAL 20
18. Test the operation of your saw prior to cutting a work piece. If you feel excessive vibration or
hear an unusual noise, immediately stop operating the saw. Correct the problem before
continued use.
19. Allow movement of the waste portion of the work piece. Do not hold it, clamp it, touch it or
use a length stop against it. The cut-off waste portion must be free to move. It could become
wedged against the blade causing a hazard.
20. Avoid awkward hand positions. It is important to position your hand no closer than four (4)
inches from the blade.
21. Do not cross your arms in front of the blade while operating the saw.
22. Do not force the blade through the work piece. Lower the blade through the work piece fast
enough to allow the blade to cut without binding or bogging down.
23. Before removing obstructed material, release the trigger switch/start button, wait for the
blade to stop moving and unplug the power cord from the electrical outlet.
24. After completing a cut, keep the Handle in the down position. Release the trigger switch/start
button and wait for the blade to stop moving.
MAINTENANCE AND SERVICE
Cleaning, Maintenance and Lubrication
1. Before each use inspect the general condition of the tool. Check for loose screws,
misalignment or binding of moving parts, cracked or broken parts, damaged electrical wiring,
and any other condition that may affect its safe operation.
2. After use clean external surfaces of the tool with clean, moist cloth. To prevent accidents,
turn OFF the tool and disconnect its power supply after use. Clean, then store the tool indoors
out of children’s reach.
3. If the blade has become dirty, use a blade cleaner (not included) to clean it. Dirty blades will
bind easily, and will often overheat and burn the wood as it cuts. Overheated blades dull
more easily.
4. If the blade has become dull, replace it. Dull blades will cause increased tear-out and ragged
edges on the cuts.
5. Occasionally clean the Slides, rotating Table components and other moving parts. Use a good
quality dry lubricant (not included) which will not attract dust.
WARNING: If the supply cord of this power tool is damaged, it must be replaced only
by a qualified service technician.
ITEM 70712 OPERATOR’S MANUAL 21
Blade Replacement
Fig. 6
Fig. 7
Fig. 8
1. Unplug the tool from its power source.
2. Lock the Blade Assembly in the raised position by twisting
in the Locking Pin.
3. Use the supplied wrench to remove the Center Cover Fixing
Bolt holding the Center Cover in place by turning it
counterclockwise (Fig. 6).
4. Raise the Blade Guard and Center Cover (Fig. 7).
5. While holding in the arbor lock button (see page 13), use the
wrenches to loosen the Arbor Bolt by turning it clockwise.
(Fig. 8)
NOTE: The Arbor Bolt has a left hand thread, so it loosens by
turning clockwise.
6. Remove the Arbor Bolt, Outer Flange and Saw Blade by
pulling them straight off the Arbor.
7. Reinstall a new blade on the Arbor. Be sure to match the
direction marked on the new blade with the direction marked
on the Saw Blade Housing.
8. Replace the Outer Flange and Arbor Bolt. Tighten the Arbor
Bolt securely using the Wrench by turning it counterclockwise.
9. Rotate the Center Cover back into place and tighten the
Center Cover Fixing Bolt using the Wrench by turning it
clockwise.
10. Release the Locking Pin.
Guide Fence Adjustment
1. The Guide holds the work piece in a fixed position while the Table and or the Blade
Assembly are adjusted in a miter or bevel angle.
2. To make accurate cuts, the Guide Fence must be perpendicular (at a 90º angle) to the Saw
Blade.
3. Before beginning work, make a test cut on scrap material with the Table set at 90º.
4. Check the cut with an accurate square. You can also reverse the two pieces, hold the cut ends
together, and hold a good straight edge along the side of the pieces.
ITEM 70712 OPERATOR’S MANUAL 22
5. If either test reveals that the cut is not a true 90º angle, you must adjust the Guide Fence
before beginning work.
6. To adjust the Guide Fence, first unplug the tool.
7. Lower the Blade Assembly and lock it in place using the Locking Pin.
8. Lay a reliable carpenter’s square on the Table with one edge along the blade and the other
along the Guide Fence. Any inaccuracy should be visible.
NOTE: The square must contact the surface of the blade, not the teeth, for an accurate reading.
9. The Guide Fence is held in place with bolts at each end. Loosen the bolts slightly, and gently
tap the Guide Fence into position using a soft mallet. Retighten the bolts and make another
test cut. Repeat the process until the Guide Fence is adjusted accurately.
10. Once the Guide Fence is accurately adjusted, tighten the bolts firmly in place. Recheck one
last time, then proceed to work.
Bevel Angle Adjustment
1. For making accurate cuts, the saw blade must be adjusted to be exactly vertical to the Table.
2. To check the angle, have the Blade Assembly in its normal upright position. Make a cut on a
piece of flat sided, fairly thick scrap material.
3. Check the cut with an accurate square. The cut should be at exactly 90º. You can also check
by rotating one cut-off piece 180º and hold the cut ends together. If the cut is not exactly
vertical, the two pieces will form a slight angle.
4. If necessary, the bevel angle can be corrected by adjusting the Bevel Adjustment Screw on
the right side under the Bevel Locking Lever.
5. Once the bevel angle is adjusted, adjust the Bevel Angle Indicator to read 0º when the saw
blade is in the vertical position. Loosen the screw holding the Indicator in place, adjust it to
be exactly over the 0º mark, then retighten the screw.
Kerf Board Adjustment or Replacement
1. If the Kerf Board becomes damaged it must be replaced.
2. Remove the four screws holding the Kerf Board in place.®
3. Install a new Kerf Board. Replace the four screws and tighten them slightly.
4. To adjust the Kerf Board, lower the Saw Blade and lock it down with the Locking Pin.
Adjust the Kerf Board so the right side of the blade slightly clears the edge of the Kerf Board.
Loosen the Bevel Lock and set the Bevel Angle at 45º left. Ensure that the left side of the
blade clears the Kerf Board. Tighten the four screws holding the Kerf Board in place.
ITEM 70712 OPERATOR’S MANUAL 23
Miter Saw Cleaning and Lubricating
1. Observe the Dust Bag while using the saw. Empty the sawdust into an appropriate container
when the bag is full.
2. Occasionally wipe or blow off sawdust that accumulates on the saw. Saw dust on the Guide
Fence can cause you to make inaccurate cuts.
3. Keep the Slides free of sawdust. Wipe or blow them off as required. Use a dry lubricant on
the slides. Do not use oil or grease lubricant, as this will attract dust.
4. Occasionally lubricate the pivot point of the Table as well as other moving parts with a dry
lubricant.
