OPERATION
CUTTING AIDS
See Figure 41.
Push sticks are devices that may be used for pushing a
workpiece through the blade in any rip cut. When making
non-through cuts or ripping narrow stock, always use a
push stick, push block, and/or featherboard so your hands
do not come within 3 inches of the saw blade. They can be
made in various sizes and shapes from scrap wood and
used in a specific project. The stick must be narrower than
the workpiece, with a 90˚ notch in one end and shaping for
a grip on the other end.
A push block has a handle fastened by recessed screws
from the underside. Use push blocks for narrow cuts and
all non-through cuts.
CAUTION:
Be sure the screws in a push block are recessed to
avoid damaging the saw or workpiece.
AUXILIARY FENCE
An auxiliary fence is a device used to close the gap between
the rip fence and the saw table. Always make and use an
auxiliary fence when ripping material 1/8 in. or thinner.
HOW TO MAKE AND ATTACH AN AUXILIARY
FENCE (FOR RIP CUTTING THIN WORKPIECE)
See Figure 42.
An auxiliary fence may be made for the saw by cutting a
piece of wood to 3/4 in. thick, 3-1/2 in. wide, and 31 in. long.
To attach the auxiliary fence to the rip fence:
 Drill two countersunk holes in the locations shown.
WARNING:
When mounting an auxiliary fence face, position
mounting hardware beyond arrows at right and left.
Keep fasteners away from blade.
 Slide two T-bolts (not included) into the rip fence groove
beyond the arrows at right and left of the label on the rip
fence.
 Match the T-bolts to the holes in the auxiliary fence and
secure it to the rip fence with a washer and nut.
 Ensure that the auxiliary fence is securely attached before
use.
HOW TO MAKE A JIG (FOR RIP CUTTING
NARROW WORKPIECE)
See Figure 43.
If ripping a narrow workpiece places the hands too close to
the blade, it may be necessary to make and use a jig.
