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 and seek additional training from expe-
rienced 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
using machine.
Eye injury hazard! Always
wear safety glasses when
using 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

Table Movement
& Lock Lever
The rotary table rotates by turning the handwheel,
which is attached to a precision worm gear
engaged with a worm wheel. The ratio between
these gears is 1:90, which means one complete
turn of the handwheel rotates the table 4°.
Besides rotating the table in precise increments,
the worm gear and wheel can be disengaged
and the table can be rotated by hand. To do this,
loosen the backlash adjustment lock and rotate
the backlash adjustment lever clockwise (see
Figure 5). This is the quickest way to use the
dividing plates provided with the rotary table when
speed of operation is important (refer to Page 16
for more information).

Figure 5. Worm gear controls.
To help maximize rigidity during operation, the
rotary table has two table lock levers. Tightening
the levers locks the table in place.
To minimize finish problems associated with gear
backlash when cutting circular slots, lightly tighten
the lock levers to create extra drag.
