Changing
Cutter Rotation
IMPORTANT: Always verify the direction of the
cutter rotation before any shaping operation. The
cutting operation should feed AGAINST direction
of cutter rotation.
The G0900 is equipped with a FOR/REV
(forward/reverse) switch, as shown in Figure 23.
In most cases, the shaper should be run in the
FOR direction.

In some instances, it will be necessary to flip the
cutter over and reverse the cutter rotation.
Whenever possible, mount the cutter so the stock
is milled on the bottom side (the side away from
the operator). This does a better job and it is safer
for the operator. Refer to Using Rub Collars,
Page 30.
