Improper Fence Location And Workpiece Feed - Bosch RA1141 Operating/Safety Instructions Manual

Additional Safety Warnings for Router Tables
Use auxiliary infeed and outfeed supports
for long or wide workpieces. Oversize
workpieces without adequate support can flip
off the table or cause the table to tip.
Use push stick, vertically and horizontally
mounted featherboards (spring sticks), and
other jigs to hold down the workpiece.
Push sticks, featherboards, and jigs eliminate
the need to hold the workpiece near the
spinning bit.
Never let go of the workpiece when routing
until the cut has been completed and the
workpiece is completely clear of the bit.
Such precautionary safety measures reduce
the risk of injury and property damage.
Featherboards aid in holding the workpiece in
position when routing on a router table. They
are not intended to hold the workpiece in place
alone when the workpiece is in contact with
the bit, or at any other time when the bit is
turning.
Always hold the workpiece against the
router table fence when routing. Such
precautionary measures increase accuracy in
routing and improve control of the workpiece,
reducing the risk of injury.
Never leave the router unattended while it
is running or before it comes to a complete
stop. Such precautionary safety measures
reduce the risk of injury and property damage.

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.
Do not use the table as a workbench or
work surface. Using it for purposes other
than routing may cause damage and make it
unsafe to use in routing.
Never stand on the table or use as a ladder
or scaffolding. The table could tip or the
cutting tool could be accidentally contacted.
When servicing the tool, use only

Follow instructions in the Maintenance
section of this manual. Use of unauthorized
parts or failure to follow maintenance
instructions can result in personal injury.
Some dust created by power sanding,
sawing, grinding, drilling, and other
construction activities contains chemicals
known to cause cancer, birth defects, or
other reproductive harm. Some examples
of these chemicals are:
•
Lead from lead-based paints
•
Crystalline silica from bricks, cement,
and other masonry products
•
Arsenic and chromium from chemically
treated lumber
Your risk from these exposures varies,
depending on how often you do this type of
work. To reduce your exposure to these
chemicals, work in a well-ventilated area, and
work with approved safety equipment, such as
those dust masks that are specially designed
to filter out microscopic particles.
