Improper Fence Location and Workpiece Feed
Do not feed the workpiece where
the majority of the workpiece is
between the fence and the bit. This creates a "fence
trap" which is dangerous for two reasons:
The front of the bit is exposed during the cutting
operation (Fig. A).
•
The bit can "Climb-cut," where the bit enters the
workpiece in the same direction as the feed direction.
•
This is likely to cause the workpiece to "climb" away
from the tabletop and may lead to loss of control
during operation (Fig. A).
Feed the workpiece only against
the rotation of the bit. Do not
"back feed" the work into the bit. The bit rotates
counterclockwise as viewed from the top of the table.
"Back feeding" the work is dangerous for two reasons:
It will cause climb-cutting where the workpiece can
"climb" off the tabletop in the direction of the bit
•
rotation, pulling the workpiece and possibly your
hands into the rotating bit (Fig. B).
It is difficult to keep the workpiece against the fence
face as the bit rotation will push the workpiece away
•
from the fence.
Important Information About Extension Cords
An extension cord with adequate
size conductors that is capable of
carrying the current for your tool must be used.
This will prevent excessive voltage drop, loss of power,
or overheating. Grounded tools must use 3-wire
extension cords that have 3-prong plugs and
receptacles.
NOTE: The smaller the gauge number, the heavier
the cord.
