Installation And Removal Of The Blade

Disconnect plug from power source before performing any assembly,

adjustment or repair to avoid possible injury.

1.The miter saw is equipped with a lock pin used to lock the miter saw in the lower position. To release, push the handle down slightly and pull the lock pin to its full out position and rotate 90°.

NOTE:If the lock pin is stuck and will not pull out when the handle is pushed down slightly, you may have to adjust the depth stop bolt (see Depth Adjustment, page 16) slightly so the handle can be pushed down and the lock pin can be pulled out.

2.Rotate the lower guard by hand. Loosen front cover screw to a point that cover plate can be lift- ed (Figure 1).

3.Rotate the cover plate counterclockwise so the blade bolt is exposed (Figure 1).

4.Press and hold the arbor lock (See figure on page page 9). Use the multi purpose tool to remove the blade bolt by turning wrench clockwise. NOTE: The blade bolt has left hand threading.
