Special Cuts - Bosch PROFACTOR GCM18V-10SDN14 Operating/Safety Instructions Manual

First-Time Use of the Auxiliary Fence
Be aware of the path of the saw
blade. Make a dry run with the saw
OFF by conducting a simulated cutting cycle, and observe
the projected path of the saw blade. Keep hands at least
six (6) inches (152mm) away from the projected path of
the saw blade.
NOTE: The first time the auxiliary fence is used, it will be cut
through by the saw blade – cutting through creates minimal
clearance which reduces splintering on the workpiece. Set
the miter angle and the bevel angle required before making
the first cut.
Clamp the workpiece, then make cut. Example: compound
cutting large crown molding flat on the table (Fig. 54).
Auxiliary Fence – Using an Auxiliary Fence when cutting
crown molding flat on the table will reduce splintering of your
workpiece and movement of small cut-off pieces. Before at-
taching the auxiliary fence, remove the saw's sliding fences.
See "Sliding Fences" on page 33.
Build auxiliary fence by following pattern in Fig. 58 – Material:
3/4" x 1-1/2" (19x38mm) wood.
Add 4 holes as dimensioned on pattern or add holes fol-
lowing the following steps:
1. Cut wood to the outside dimensions shown and tempo-
rarily attach to saw's stationary fence (Fig. 54, 12) using
two C-clamps.
2. Use 1/4" (6mm) drill bit to drill first through existing
holes in the rear of the stationary fence (12) and then
through the wood.
3. Remove wood, countersink the front of the wood and
permanently attach to saw's fence (12) with hardware
shown in Fig. 58.

when making extreme bevel, miter or compound cuts.
Cutting bowed material and round material are only two ex-
amples of special cuts.
Cutting Bowed Material
If workpiece is bowed or warped, clamp it with the outside
bowed face toward the fence (Fig. 59, 12). Always make cer-
tain that there is no gap between the workpiece, fence and
table (22) along the line of cut. Bent or warped workpieces
can twist or rock and may cause binding on the spinning saw
blade while cutting.
