Manual Before Operating This Machine
The purpose of safety symbols is to attract your attention to possible hazardous conditions.
This manual uses a series of symbols and signal words intended to convey the level of importance of the safety messages. The progression of symbols is described below. Remember that
safety messages by themselves do not eliminate danger and are not a substitute for proper
accident prevention measures. Always use common sense and good judgment.
Indicates an imminently hazardous situation which, if not avoided,
WILL result in death or serious injury.
Indicates a potentially hazardous situation which, if not avoided,
COULD result in death or serious injury.
Indicates a potentially hazardous situation which, if not avoided,
MAY result in minor or moderate injury. It may also be used to alert
against unsafe practices.
This symbol is used to alert the user to useful information about
NOTICE

Models T1190-92 (Mfd. Since 3/17)
WEARING PROPER APPAREL. Do not wear
clothing, apparel or jewelry that can become
entangled in moving parts. Always tie back or
cover long hair. Wear non-slip footwear to reduce
risk of slipping and losing control or accidentally
contacting cutting tool or moving parts.
HAZARDOUS DUST. Dust created by machinery
operations may cause cancer, birth defects, or
long-term respiratory damage. Be aware of dust
hazards associated with each workpiece material. Always wear a NIOSH-approved respirator to
reduce your risk.
HEARING PROTECTION. Always wear hearing protection when operating or observing loud
machinery. Extended exposure to this noise
without hearing protection can cause permanent
hearing loss.
REMOVE ADJUSTING TOOLS. Tools left on
machinery can become dangerous projectiles
upon startup. Never leave chuck keys, wrenches,
or any other tools on machine. Always verify
removal before starting!
USE CORRECT TOOL FOR THE JOB. Only use
this tool for its intended purpose—do not force
it or an attachment to do a job for which it was
not designed. Never make unapproved modifications—modifying tool or using it differently than
intended may result in malfunction or mechanical
failure that can lead to personal injury or death!
AWKWARD POSITIONS. Keep proper footing
and balance at all times when operating machine.
Do not overreach! Avoid awkward hand positions
that make workpiece control difficult or increase
the risk of accidental injury.
CHILDREN & BYSTANDERS. Keep children and
bystanders at a safe distance from the work area.
Stop using machine if they become a distraction.
GUARDS & COVERS. Guards and covers reduce
accidental contact with moving parts or flying
debris. Make sure they are properly installed,
undamaged, and working correctly BEFORE
operating machine.
FORCING MACHINERY. Do not force machine.
It will do the job safer and better at the rate for
which it was designed.
NEVER STAND ON MACHINE. Serious injury
may occur if machine is tipped or if the cutting
tool is unintentionally contacted.
STABLE MACHINE. Unexpected movement during operation greatly increases risk of injury or
loss of control. Before starting, verify machine is
stable and mobile base (if used) is locked.
USE RECOMMENDED ACCESSORIES. Consult
this owner’s manual or the manufacturer for recommended accessories. Using improper accessories will increase the risk of serious injury.
UNATTENDED OPERATION. To reduce the
risk of accidental injury, turn machine OFF and
ensure all moving parts completely stop before
walking away. Never leave machine running
while unattended.
MAINTAIN WITH CARE. Follow all maintenance
instructions and lubrication schedules to keep
machine in good working condition. A machine
that is improperly maintained could malfunction,
leading to serious personal injury or death.
DAMAGED PARTS. Regularly inspect machine
for damaged, loose, or mis-adjusted parts—or
any condition that could affect safe operation.
Immediately repair/replace BEFORE operating
machine. For your own safety, DO NOT operate
machine with damaged parts!
MAINTAIN POWER CORDS. When disconnecting cord-connected machines from power, grab
and pull the plug—NOT the cord. Pulling the cord
may damage the wires inside. Do not handle
cord/plug with wet hands. Avoid cord damage by
keeping it away from heated surfaces, high traffic
areas, harsh chemicals, and wet/damp locations.
EXPERIENCING DIFFICULTIES. If at any time
you experience difficulties performing the intended operation, stop using the machine! Contact our
Technical Support at (570) 546-9663.

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 1:72, which means one complete
turn of the handwheel rotates the table 5°.
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 7).
To help maximize rigidity during operation,
the rotary table has two table lock levers (see
Figure 7). Tightening the levers locks the table

DRO Auto & Handle
Settings
There are two different modes for machine operation using the DRO: Auto and Handle. It is important to know the difference between the two for
proper machine operation and safety.
To operate in Auto Mode:
1. Motor starts running after pressing Start
button.
Angular Indexing
Angular indexing is the process used to create
evenly spaced holes in a round workpiece. Always
ensure your rotary table is properly aligned on
the X-axis of the mill before beginning angular
indexing.
Basic Example:
You are making a flange and need to place six
holes 60° apart for the bolt pattern in Figure 22.
2. Motor stops when the Angle value reaches
the same as the preset value.
3. Motor will run again when the Time value
reaches the preset value. It will then run the
same angle as the preset value.
4. After the cycle repeats, rotary table will stop
running when the angle is infinitely near 360°.
To operate in Handle Mode:
1. Rotary table starts running after pressing the
control dial. Hold down the dial to adjust the
angle of the table.
2. Working presets are the same as in Auto
Mode from here.
3. To reset the values, press the Stop button.

1. Rotate handwheel before making first hole to
take up any play in worm gear.
⁄N

2. Make your first hole, then rotate handwheel
12 times.
Note: If you rotate handwheel too far, do not
back up to the number. You must back up
one revolution and dial back to the desired
number, then lock table in place to locate
the second hole. This procedure eliminates
errors due to backlash in worm gear.
Models T1190-92 (Mfd. Since 3/17)
Mounting Tailstock
Models T1190 and T1192 come with a tailstock.
The tailstock supports larger workpieces when
the rotary table is in the vertical position, while
maintaining a high level of accuracy.
1. Ensure chuck is installed on rotary table, then
secure rotary table to mill table in vertical
position.
5. Move table along X-axis and indicate horizontal centerline of workpiece near rotary
table. If there is an offset, adjust position of
tailstock half the distance of the offset and
recheck (see Figure 24).
2. Install tailstock on mill table so dead center of
tailstock is roughly in line with center of rotary
table.
3. Mount center-drilled, parallel workpiece
between chuck and tailstock (see Figure 23).
Note : Workpiece should be checked for par-
allelism and concentricity.
4. Mount a dial indicator in mill spindle and
indicate off of a horizontal center line of
workpiece near tailstock (see Figure 23).
Figure 24. Adjusting tailstock for offset.
6. Continue to make this adjustment until zero
movement is indicated all along the travel.
7. Tighten tailstock mounting bolts and recheck.
To align Z-axis:
1. Repeat Steps 5 –7 from above, only this time
indicate off vertical center line of workpiece.
2. Make your adjustments by slightly loosening adjustment bolt and raising or lowering
tailstock dead center in appropriate direction
(see Figure 25).

power before adjustments,
maintenance, or service.
Oi l Ty pe .... Grizzly T26685 or ISO 32 Equivalent
Oil Amount ......................................1 or 2 Squirts
Lubrication Frequency ................................. Daily
Schedule
For optimum performance from your rotary table,
follow this maintenance schedule and refer to any
specific instructions given in this section.
Daily:
• Clean and lubricate the rotary table.
• Dress the machined surfaces.
• Check/resolve any unsafe condition.
Monthly:
• Disassemble and clean the rotary table.
Cleaning &
Protecting
It is essential that the rotary table be cleaned
after every use, and the surfaces oiled with a light
machine oil to prevent corrosion.
DO NOT use compressed air to clean your
rotary table. Chips or debris may become lodged
between the moving parts, reducing the life and
accuracy of the device. Instead, use a stiff-bristled
brush to remove the chips and swarf, then wipe
down the surfaces with a clean shop rag.
Every 80 hours of use, completely disassemble
the rotary table, then thoroughly clean each part
and relubricate.
-24-
This rotary vise has 2 ball oilers that should be
oiled on a daily basis before beginning operation.
Refer to Figure33 for their locations.
Ball
Oilers
Figure 33. Location of ball oilers.
Ball Oilers
Proper lubrication of ball oilers is done with a
pump-type oil can that has a plastic or rubberized cone tip. We do not recommend using metal
needle or lance tips, as they can push the ball too
far into the oiler, break the spring seat, and lodge
the ball in the oil galley.
Lubricate the ball oilers before and after machine
use, and more frequently under heavy use. When
lubricating ball oilers, first clean the outside surface to remove any dust or grime. Push the rubber or plastic tip of the oil can nozzle against the
ball oiler to create a hydraulic seal, then pump the
oil can once or twice. If you see sludge and contaminants coming out of the lubrication area, keep
pumping the oil can until the oil runs clear. When
finished, wipe away any excess oil.

WARRANTY & RETURNS
Grizzly Industrial, Inc. warrants every product it sells for a period of 1 year to the original purchaser from
the date of purchase. This warranty does not apply to defects due directly or indirectly to misuse, abuse,
negligence, accidents, repairs or alterations or lack of maintenance. This is Grizzly’s sole written warranty
and any and all warranties that may be implied by law, including any merchantability or fitness, for any particular purpose, are hereby limited to the duration of this written warranty. We do not warrant or represent
that the merchandise complies with the provisions of any law or acts unless the manufacturer so warrants.
In no event shall Grizzly’s liability under this warranty exceed the purchase price paid for the product and
any legal actions brought against Grizzly shall be tried in the State of Washington, County of Whatcom.
We shall in no event be liable for death, injuries to persons or property or for incidental, contingent, special,
or consequential damages arising from the use of our products.
To take advantage of this warranty, contact us by mail or phone and give us all the details. We will then issue
you a “Return Number,’’ which must be clearly posted on the outside as well as the inside of the carton. We
will not accept any item back without this number. Proof of purchase must accompany the merchandise.
The manufacturers reserve the right to change specifications at any time because they constantly strive to
