Bosch RA1180 Operating/Safety Instructions Manual page 27

Make certain that the router is not
plugged into a power outlet when installing into the
table, removing from table, making adjustments or
changing accessories. Router could accidentally start.
In the event of a power failure,
blown fuse, tripped circuit breaker, or router "stall
out" while routing, turn off the switch and unplug
the switch from the power outlet until the cause of
the problem has been found and corrected.
JOINTING (FULL EDGE CUTTING)
Using a router table for jointing has several advantages
over other methods, such as using a freestanding
power jointer, though it cannot completely replace a
power jointer.
• Small and short pieces of wood can be safely and
successfully routed because the opening between
the faces can be adjusted down to a minimum.
• Because routers spin much faster than typical joint-
ers, the cut quality is much better. This is especially
useful on types of woods that are prone to tear-out.
NOTE: Jointing is the only routing operation using the
fence in which the left lower fence is offset from the
right lower fence. For all other routing operations,
both lower fences are always aligned.
For maximum strength and accuracy, boards that
are to be joined together should be smooth and true.
The edges should be true to the workpiece surface.
Install 1/2" straight bit or spiral bit in the router,
because they are the strongest bits with the least
potential for deflecting. To further minimize the
potential for deflecting, use a bit with the shortest
possible cutter height sufficient to do the job.
1. Remove the left lower fence from the upper fence
and assemble it to the upper fence as shown in
Fig. 32. The small identifying grooves in the lower
fence should face outward as shown. This will
offset the left side lower fence from the right fence.
The two clamping knobs should be loose while
doing this.
2. Install the feather board on the left side of the
table as shown in Fig. 33. See "POSITIONING
THE TABLE TOP FEATHER BOARD".
3. Install a straight bit in the router.
4 Position both lower fences from SIDE-TO-SIDE so
that they clear the bit by 1/4".
5. Tighten the four clamping knobs holding the fences
in place.
6. Place a straight edge or a straight piece of wood
on the table so that it rests against the left fence,
as shown in Detail 33.
