ADJUSTMENTS WARNING: To prevent accidental starting that could cause serious personal injury, always remove the battery pack from the tool when assembling parts. The compound miter saw has been adjusted at the factory for making very accurate cuts. However, some of the components might have been jarred out of alignment during shipping. Also, over a period of time, readjustment will probably become necessary due to wear. After unpacking the saw, check the following adjustments before you begin using the saw. Make any readjustments that are necessary and periodically check the parts alignment to make sure that the saw is cutting accurately. CAUTION: Do not start the compound miter saw without checking for interference between the blade and the throat plate. Damage could result to the blade if it strikes the throat plate during operation of the saw. POSITIVE STOP ADJUSTMENTS See Figure 36. Note: These adjustments were made at the factory and normally do not require readjustment. To adjust:  Remove the battery pack from the tool.  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.  If the blade is out of square, adjust by tightening or loosening the positive stop adjustment screw.  Retighten bevel lock knob. 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 two scale indicators, one 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. PIVOT ADJUSTMENTS Note: These adjustments were made at the factory and normally do not require readjustment. TRAVEL PIVOT ADJUSTMENT  The saw arm should rise completely to the up position by itself.  If the saw arm does not raise by itself or if there is play in the pivot joints, have saw repaired by at your nearest authorized service center. Bevel Pivot Adjustment  The compound miter saw should bevel easily by loosening the bevel lock knob and tilting the saw arm to the left.  If movement is tight or if there is play in the pivot, have saw repaired by at your nearest authorized service center.
