LOOSE PARTS LIST

UNPACKING

This product requires assembly.

• Carefully lift the saw from the carton by the carrying handle and the saw base, and place it on a level work surface.
  NOTE: This product is heavy. To avoid back injury, lift with your legs, not your back, and get help when needed.
• This saw has been shipped with the saw arm secured in the down position. To release the saw arm, push down on the “D” handle, cut the tie-wrap, and pull out on the lock pin.
• Lift the saw arm by the handle. Hand pressure should remain on the “D” handle to prevent sudden rise upon release of the tie wrap.
• Inspect the product carefully to make sure no breakage or damage occurred during shipping.
• Do not discard the packing material until you have carefully inspected and satisfactorily operated the tool.
• The saw is factory-set for accurate cutting. After assembling it, check for accuracy. If shipping has influenced the settings, refer to specific procedures explained in this manual.

Mounting Holes

See Figure 7.

• The compound miter saw should be mounted to a firm supporting surface such as a workbench. Four bolt holes have been provided in the saw base for this purpose. Each of the four mounting holes should be bolted securely using 3/8 in. machine bolts, lock washers, and hex nuts (not included). Bolts should be of sufficient length to accommodate the saw base, lock washers, hex nuts, and the thickness of the workbench. Tighten all four bolts securely.
• The hole pattern for mounting to a workbench is shown in figure 7. Carefully check the workbench after mounting to make sure that no movement can occur during use. If any tipping, sliding, or walking is noted, secure the workbench to the floor before operating.

OPERATION

CUTTING WITH YOUR COMPOUND MITER SAW

To Miter Crosscut /Straight crosscut

• See Figures 32 – 33.
• A crosscut is made by cutting across the grain of the workpiece. A straight cross-cut is made with the miter table set at the 0° position. Miter cross-cuts are made with the miter table set at some angle other than zero.
• Pull out the lock pin and lift the saw arm to its full height.
• Loosen the miter lock handle. Rotate the miter lock handle approximately one-half turn to the left to loosen.
• Press the miter lock plate down with your thumb and hold.
• Rotate the control arm until the pointer aligns with the desired angle on the miter scale
• Release the miter lock plate.
• Note: You can quickly locate 0°, 22 -1/2° left or right, and 45° left or right by releasing the lock plate as you rotate the control arm. The lock plate will seat itself in one of the positive stop notches, located in the miter table frame.
• Tighten the miter lock handle securely.
• Place the workpiece flat on the miter table with one edge securely against the fence. If the board is warped, place the convex side against the fence. If the concave edge of a board is placed against the fence, the board could collapse on the blade at the end of the cut, jamming the blade.
• When cutting long pieces of lumber or molding, support the opposite end of the stock with a roller stand or with a work surface level with the saw table. See Figure 38.
• Align the cutting line on the workpiece with the edge of the saw blade.
• Grasp the stock firmly with one hand and secure it against the fence. Use the optional work clamp or a C-clamp to secure the workpiece when possible.
• Before turning on the saw, perform a dry run of the cutting operation just to make sure that no problems will occur when the cut is made.
• Grasp the saw handle firmly then squeeze the switch trigger. Allow several seconds for the blade to reach maximum speed.
• Slowly lower the blade into and through the workpiece.
• Release the switch trigger and allow the blade to stop rotating before raising the blade out of the workpiece. Wait until the electric brake stops the blade from turning before removing the workpiece from the miter table.

TO Bevel Cut

• See Figures 34 – 35.
• A bevel cut is made by cutting across the grain of the workpiece with the blade angled to the workpiece. A straight bevel cut is made with the miter table set at the zero-degree position and the blade set at an angle between 0° and 45°.
  • NOTE: It may be necessary to adjust or remove the sliding miter fence to ensure proper clearance prior to making the cut.
• Pull out the lock pin and lift the saw arm to its full height.
• Loosen the miter lock handle. Rotate the miter lock handle approximately one-half turn to the left to loosen.
• Press the miter lock plate down with your thumb and hold.
• Rotate the control arm until the pointer aligns with zero on the miter scale.
• Release the miter lock plate.
• Note: You can quickly locate zero by releasing the lock plate as you rotate the control arm. The lock plate will seat itself in one of the built-in positive stop notches, located in the miter table frame.
• Tighten the miter lock handle securely.
• Adjustments of the miter fence must be made to correspond to the desired angle of the bevel cut prior to tilting the saw arm. The bevel scale is marked for 15°,
  30°, and 45°. Loosen the fence screw on the miter fence, slide the fence to the desired position, and retighten the fence screw.
• The 45° triangle on the miter fence provides for the maximum clearance required for adjusting the miter saw’s angle when making a bevel or compound cut.
• Loosen the bevel lock knob and move the saw arm to the left to the desired bevel angle.
• Bevel angles can be set from 0° to 45°.
• Align the indicator point for the desired angle.
• Once the saw arm has been set at the desired angle, securely tighten the bevel lock knob.
• Place the workpiece flat on the miter table with one edge securely against the fence. If the board is warped, place the convex side against the fence. If the concave edge of a board is placed against the fence, the board could collapse on the blade at the end of the cut, jamming the blade. See Figures 40 – 41.

To Compound Miter Cut

• See Figure 37.
• A compound miter cut is a cut made using a miter angle and a bevel angle at the same time. This type of cut is used to make picture frames, cut molding, make boxes with sloping sides, and for certain roof framing cuts.
  NOTE: It may be necessary to adjust or remove the sliding miter fence to ensure proper clearance prior to making the cut. To make this type of cut the control arm on the miter table must be rotated to the correct angle and the saw arm must be tilted to the correct bevel angle. Care should always be taken when making compound miter setups due to the interaction of the two angle settings.
• Adjustments of miter and bevel settings are interdependent with one another. Each time you adjust the miter setting you change the effect of the bevel setting. Also, each time you adjust the bevel setting you change the effect of the miter setting. It may take several settings to obtain the desired cut. The first angle setting should be checked after setting the second angle, since adjusting the second angle affects the first. Once the two correct settings for a particular cut have been obtained, always make a test cut in scrap material before making a finish cut in good material.
• Place the workpiece flat on the miter table with one edge securely against the fence. If the board is warped, place the convex side against the fence. If the concave edge of a board could collapse on the blade at the end of the cut, jamming the blade. See Figures 40 – 41.
• When cutting long pieces of lumber or molding, support the opposite end of the stock with a roller stand or with a work surface level with the saw table. See Figure 38.
• Align the cutting line on the workpiece with the edge of the saw blade.
• Grasp the stock firmly with one hand and secure it against the fence. Use the optional work clamp or a C-clamp to secure the workpiece when possible.
• Before turning on the saw, perform a dry run of the cutting operation just to make sure that no problems will occur when the cut is made.
• Grasp the saw handle firmly then squeeze the switch trigger. Allow several seconds for the blade to reach maximum speed.
• Slowly lower the blade into and through the workpiece. See Figures 36 – 37.

CUTTING COMPOUND MITERS

• To aid in making the correct settings, the compound angle setting chart below has been provided. Since compound cuts are the most difficult to accurately obtain, trial cuts should be made in scrap material, and much thought and planning made, prior to making the required cut

ADJUSTMENTS

DEPTH STOP ADJUSTMENTS

• See Figure 43.
• Unplug the saw.
• To adjust the depth stop use a 10 mm wrench and loosen the hex nut located on the side of the miter saw housing.
• Use a 5 mm hex key wrench to adjust the depth stop adjustment screw. The saw blade is lowered by turning the screw counterclockwise and raised by turning the screw clockwise.
• Lower the blade into the miter table. Check blade clearance and maximum cutting distance (distance from the fence where the blade enters) to the front of the miter table slot.
• Readjust if necessary.
• Tighten the hex nut with a 10 mm wrench or adjustable wrench.
• To prevent the depth stop adjustment screw from turning while tightening the hex nut, carefully hold it with the hex key wrench while tightening the hex nut

POSITIVE STOP ADJUSTMENTS

• See Figure 44.
• Note: These adjustments were made at the factory and normally do not require readjustment.
• To adjust:
  • Unplug the saw.
  • Using two wrenches (one on the lock nut and one for the positive stop adjustment screw), loosen the lock nut securing the positive stop adjustment screw.
  • Loosen the bevel lock knob by turning the knob counterclockwise.
  • Square the blade to the miter table as described in the Assembly section of this manual.
  • Retighten bevel lock knob. Next, retighten lock nut securing the positive stop adjustment screw. Recheck blade-to-table alignment.
• Note: The above procedure can be used to check blade squareness of the saw blade to the miter table at both 0° and 45° angles.
• The saw has three scale indicators, two on the bevel scale and one on the miter scale. After squaring adjustments have been made, it may be necessary to loosen the indicator screws and reset them to zero.

MAINTENANCE

LUBRICATION

• All of the bearings in this product are lubricated with a sufficient amount of high-grade lubricant for the life of the unit under normal operating conditions. Therefore, no further lubrication is required.

Brush REPLACEMENT

• See Figure 46.
• The saw has externally accessible brush assemblies that should be periodically checked for wear. Proceed as follows when replacement is required:
• Unplug the saw.
• Remove the brush cap with a screwdriver. The brush assembly is spring-loaded and will pop out when you remove brush cap.
  • Remove brush assembly.
  • Check for wear. Replace both brushes when either has less than 1/4 in. length of carbon remaining. Do not replace one side without replacing the other.
  • Reassemble using new brush assemblies. Make sure the curvature of the brush matches the curvature of the motor and that brush moves freely in the brush tube.
  • Make sure the brush cap is oriented correctly (straight) and replace it.
  • Tighten the brush cap securely. Do not over-tighten.

Changing the Batteries

• See Figure 47.
• Unplug the saw.
•  Rotate and hold the lower blade guard up.
• Using the hex key (1/16 in.) provided, loosen the screw then separate the cover from the laser guide.
• Lower the blade guard.
• Remove the three-button cell batteries.
  • Note: Replace the batteries with button cell batteries that have a rating of 1.5 volts and 100 mAh (milliampere-hour) minimum (number 76 series or equivalent).
• When replacing the batteries, the laser guide should be thoroughly cleaned. Use a soft paintbrush, or similar device, to remove all sawdust and debris.
• After cleaning the laser guide and replacing the batteries, secure the battery cover to the laser guide using the screw. Tighten the screw securely.
