the fence and/or
workpiece are improperly located
anytime, it would result in:
• The front of the bit is exposed during the
actual cutting (Fig. A).
The bit must not enter
the workpiece in the same direction as
the feed direction, which is likely to
cause the workpiece to "climb" and may
lead to loss of control during operation
"Fence Traps': One type of improper fence
location warrants special attention: "Fence
traps" happen when the fence is positioned
so far back that front side (power switch
side) of the workpiece would be behind the
Fence traps are
dangerous for two reasons:
• Exposure of the bit on the front side
(power switch side) of the workpiece.
• Likelihood of climb cut, which can cause
loss of control.
Fig. A shows a fence trap.
Do not feed the workpiece from left to right:
• It would cause climb-cutting.
• It would be difficult to keep the
workpiece against the fence faces
because the bit rotation would push
the workpiece away from the fence.
