Compound Cuts - Bosch GCM18V-12SD Operating/Safety Instructions Manual

Compound Cuts

For compound cutting, ad-
just sliding fence (Fig. 54,
12) clear of blade path and guard system.
Before
check that there is no inter-
ference between moving and stationary parts
of the saw. These miter and bevel combinations
may result in interference between the sliding
and stationary parts of the saw or between the
sliding parts and the work piece.

What's a Compound Cut?
• A "compound cut" is a single cross-cut
made with the saw blade preset at two
angles combining a miter angle (relative to
the vertical fence) with a bevel angle (rela-
tive to the horizontal table).
• Miter angles will be with the table rotated
away from 0° and within this saw's range
from 52° left to 60° right.
• A bevel angle is when the blade is tilted
away from 0°. This saw's range is from 47°
left to 47° right.
• A compound cut can be made as a chop cut
or a slide cut. (See "Chop Cuts" on page
37 or "Slide Cuts" on page 38.)

Making a Compound Cut
Use clamping position that
does not interfere with op-
eration. Before switching ON, lower head as-
sembly to make sure clamp clears guard and
head assembly.
Be aware of the path of the
saw blade. Make a dry run
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.
Follow these instructions for making your com-
pound cut:
1. Extend the fence (Fig. 54, 12).
2. Properly position workpiece. Make sure
workpiece is clamped firmly against the ta-
ble (22) or the fence (12).
3. Set miter angles for miter cuts according
to the instructions in "Miter Cuts" on page
39, and set bevel angles for bevel cuts ac-
cording to the instructions in "Bevel Cuts"
on page 41.
4. Follow the procedures "Chop Cuts" on page
37 or "Slide Cuts" on page 38.
5. Wait until saw blade comes to a complete
stop before returning head assembly (Fig.
49, 28) to the raised position and then re-
move workpiece.
Cutting crown molding flat on the table (22)
requires compound cuts. See "Cutting Crown
Molding" on page 45.
