Special Cuts - Bosch GCM18V-12SD 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 – cut-
ting 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. 57).
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 attach-
ing the auxiliary fence, remove the saw's sliding
fences. See "Sliding Fences" on page 32.
Build auxiliary fence by following pattern in Fig.
61 – Material: 3/4" x 1-1/2" (19x38mm) wood.
Add 4 holes as dimensioned on pattern or add
holes following the following steps:
1. Cut wood to the outside dimensions shown
and temporarily attach to saw's stationary
fence (Fig. 57, 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. 61.

with the battery pack disconnected and the
saw switched 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.
from hand to saw blade, extend the sliding
fence and base extensions when making ex-
treme bevel, miter or compound cuts.
Cutting bowed material and round material are
only two examples of special cuts.
Cutting Bowed Material
If workpiece is bowed or warped, clamp it with
the outside bowed face toward the fence (Fig.
62, 12). Always make certain that there is no
gap between the workpiece, fence and table
(22) along the line of cut. Bent or warped work-
pieces can twist or rock and may cause binding
on the spinning saw blade while cutting.
