Replacing
Spindle Bearings
Should a bearing fail, your shaper will develop
a noticeable rumble, worse so when the machine
is put under load. If the bad bearing is not
replaced, it will eventually seize—possibly doing
damage to the machine. Bearings are standard
sizes and can be replaced through our exclusive
dealer, Grizzly Industrial, Inc.

pressure is applied in the next step.

Adjusting
Table Inserts
The two inner table inserts are held in place by a
large, outer insert ring, which should be adjusted
level with the table top. This is necessary to
avoid the workpiece catching on the insert rings
during operation, causing an unsafe condition
and poor cutting results.
