Bosch GCM12SD - Dry Run

Use sliding base extensions, sliding fence, and ad-
ditional workpiece supports (see page 34) to
properly support the workpiece and hold or
clamp it outside of the “No Hands Zone”.
Workpiece can be held against table and fence by
hand only outside of the “No Hands Zone”.
•Hold workpiece firmly against table and fence
to prevent movement.
•Keep hands in position until trigger has been
released and blade has completely stopped.
•Never place hands on mechanism components.
•Keep feet firmly on the floor and maintain
proper balance.
•Follow the miter arm when mitering left or
right. Stand slightly to the side of the saw
blade.
Be aware of the path of the
saw blade. Make a DRY
RUN with the saw “OFF” by conducting a simu-
lated cutting cycle, and observe the projected
path of the saw blade. Keep hands out of the
path of saw blade.
DRY RUN – It is important to know where the
blade will intersect with the workpiece during
cutting operations. Always perform the simulated
cutting sequence with the power tool switched
“OFF” to gain an understanding of the projected
path of the saw blade. Mentally note where the
path of the saw blade will fall and set up your
work to keep your hands and arms out of the path
of the spinning blade. Adjust your clamps and
fences so that the smooth lower guard and cut-
ting action is not interfered with during cutting
operation.
The lower guard may not
automatically open under
certain cutting conditions; for example, when
trying to cut workpieces that are near the max-
imum cutting height capacity. Under these
conditions or during the blade travel motion of
cut, the workpiece can stop the lower guard
movement before the downward motion of the
arm could pre-open the lower guard.
If this occurs:
Workpiece must be securely clamped. This
frees a hand to raise the guard by the lip just
enough to clear the workpiece (see Fig. 32).
Start the saw and begin your cut. Once you
have cleared the position where the lower guard
may bind, release the guard and it will continue
to operate automatically as you cut.
