16 ASSEMBL Y NOTE: Many of the illustrations in this manual show only portions of the compound miter saw . This is intentional so that we can clearly show points being made in the illustrations. Never operate the saw without all guards securely in place and in good operating condition.
17 WARNING: Make sure the spindle lock button is not engaged before reconnecting saw to power sour ce. Never engage spindle lock button when blade is r otating. INST ALLING THE BLADE See Figure 12. WARNING: A 12 in. blade is the maximum blade capacity of the saw .
18 18 ASSEMBL Y CUTTING A SLOT IN THE ZERO CLEARANCE THROA T PLA TE In order to use your compound miter saw , you must cut a slot through the zero clearance throat plate to allow for blade clearance.
19 ADJUSTING THE MITER LOCK LEVER See Figures 14 - 15. Prior to squaring the saw blade to the fence, check the miter lock lever for proper adjustment. The blade must be set at an “unindexed” miter position other than 0˚, 15˚, 22.5˚, 31.6˚, and 45˚ to test.

21 ASSEMBL Y ADJUSTING THE BEVEL LOCK LEVER See Figures 21 - 23. Prior to squaring the saw blade to the miter table, check the bevel lock lever for proper adjustment. The blade must be set at an “unindexed” bevel position other than 0 ° , 22.5 ° , 33.
22 SCALE INDICA TOR INDICA TOR SCREW SQUARING THE BLADE TO THE MITER T ABLE See Figures 24 - 27. Unplug the saw . Pull the saw arm all the way down and lock in transport position. Lift the miter lock lever to unlock. Rotate the miter table and set the saw at 0 ° miter .
23 OPERA TION WARNING: Do not allow familiarity with tools to make you careless. Remember that a careless fraction of a second is sufficient to inflict sever e injury . WARNING: Always wear safety goggles or safety glasses with side shields when operating tools.
24 Fig. 28 OPERA TION WORK CLAMP CROSS CUT MITER THUMBWHEEL The miter thumbwheel, when used with the miter lock lever lifted (unlocked), can release the miter table from pre-set index points. T o align with miter scale: Lift the miter lock lever to unlock.
25 TO BEVEL CUT See Figures 30 - 32. A bev el c u t is mad e by cu tt in g acro ss t he gra in o f th e workp iece with the blade angled to the workpiec e. A stra ight bevel cut is made with the miter table set at the zero degree position and the blade set at an angle.
26 TO COMPOUND MITER CUT See Figure 33. 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.
27 SUPPORTING LONG WORKPIECES See Figures 34 - 35. Long workpieces need extra supports. Supports should be placed along the workpiece so it does not sag. The support should let the workpiece lay flat on the base of the saw and miter table during the cutting operation.
28 OPERA TION MAKING AN AUXILIAR Y FENCE See Figure 37. Certain unusual cuts may benefit from a thicker miter fence (au xil iary fe nce) due to the siz e an d po siti on of the wor kpie ce. The holes provided in the miter fence are ther e for just this pu rp os e.
29 CUTTING COMPOUND MITERS T o 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 your requir ed cut.
30 OPERA TION CUTTING CROWN MOLDING The following chart illustrates the miter and bevel angle settings of the miter saw for both 52˚/38˚ and 45˚/45˚ crown molding, when the angle between the walls run from 67˚ to 146˚.
31 When cutting cro wn mold ing by this method, the bev el angle should be set at 33.85 ° . The miter angle should be set at 31.6 ° either right or left, depending on the desired cut for the application. See the chart below for correct angle settings and correct positioning of cr own molding on miter table.
32 OPERA TION MAKING A CROWN MOLDING JIG See Figure 39. A crown molding jig will need to be made when cutting crown molding with no required bevel setting. The jig holds the crown molding in place during the cutting operation. When using this method, the saw can be quickly adjusted for corners that are not 90 ° square.
33 CUTTING WARPED MA TERIAL See Figures 40 - 41. When cutting warped material, always make sure it is positioned on the miter table with the convex side against the fence as shown in figure 40. If the warped materia l is positione d the wro ng way as shown in figure 40, it will pinch the blade near the completion of the cut.
34 WARNING: When servicing, use only identical replacement parts. Use of any other part may create a hazard or cause product damage. WARNING: Always wear safety goggles or safety glasses with side shields during power tool operation or when blowing dust.
35 BRUSH REPLACEMENT See Figure 43. The saw has exter nally accessible brush assemblies that should be periodically checked for wear . Proceed as follows when r eplacement is requir ed: Unplug the saw . WARNING: Failure to unplug the saw could resul t in accidental starting causing serious injury .
