Model T1243 (Mfd. Since 02/18)
SECTION 3: OPERATIONS
Operation Overview
The purpose of this overview is to provide the nov-
ice machine operator with a basic understanding
of how the machine is used during operation, so
the machine controls/components discussed later
in this manual are easier to understand.
Due to the generic nature of this overview, it is
not intended to be an instructional guide. To learn
more about specific operations, read this entire
manual, seek additional training from experienced
machine operators, and do additional research
outside of this manual by reading "how-to" books,
trade magazines, or websites.
To reduce your risk of
serious injury, read this
entire manual BEFORE
using machine.
To reduce risk of eye injury from flying
chips or lung damage from breathing dust,
always wear safety glasses and a respirator
when operating this machine.
If you are not experienced with this type
of machine, WE STRONGLY RECOMMEND
that you seek additional training outside of
this manual. Read books/magazines or get
formal training before beginning any proj-
ects. Regardless of the content in this sec-
tion, Grizzly Industrial will not be held liable
for accidents caused by lack of training.
The T1243 rotary table rotates by turning the
3" handwheel, which is attached to a precision
worm gear engaged with a worm wheel. The ratio
between these gears is 90:1, which means one
complete turn of the handwheel rotates the table
4° (see
Figure 5).
To maximize rigidity during operation, the rota-
ry table has two table locks (see
Figure 6).
Tightening the levers locks the table in place.

To minimize finish problems associated with gear
backlash when cutting circular slots, lightly tighten
the locks to create extra drag.
