INSTALLING MITER FENCES
See Figure 12.
 Turn the fence lock knob counterclockwise, to clear fixed
fence slots.
 Install the sliding miter fence. Lower fence into fence
slots. Be sure side of fence lines up flush with side of
fixed fence.

DUST BAG AND FRAME ASSEMBLY
See Figure 13.
To install the dust bag and frame assembly, slide the open
end of the frame onto the exhaust port.
For efficient operation, empty the dust bag before it is half
full. This will permit better air flow through the bag.
NOTE: The exhaust port also accepts a 1-1/4 in. vacuum
hose and 1-1/4 in. wet/dry vacuum adaptors.
