OPERATION
CUTTING WITH YOUR SLIDING COMPOUND
MITER SAW
WARNING:
When using a work clamp or C-clamp to secure
your workpiece, clamp workpiece on one side of
the blade only. The workpiece must remain free
on one side of the blade to prevent the blade
from binding in workpiece. The workpiece binding
the blade will cause motor stalling and kickback.
This situation could cause an accident resulting in
possible serious personal injury.
WARNING:
NEVER move the workpiece or make adjustment to
any cutting angle while the saw is running and the
blade is rotating. Any slip can result in contact with
the blade causing serious personal injury.
WARNING:
Do not try to cut narrow pieces using the sliding
feature. Failure to heed this warning could result in
serious personal injury.
LED LIGHTING SYSTEM
See Figure 31.
The LED lighting system casts the shadow of the blade onto
the workpiece. This results in greater accuracy of cuts and
requires no adjustments.
To use this feature, turn the LED switch on.
Bring the saw arm down so that the blade is approximately
1/4 in. from the workpiece. The shadow of the blade will be
projected onto the workpiece, indicating where the blade
teeth will make contact as the cut is made.
