This manual provides critical safety instructions on the proper setup,
operation, maintenance, and service of this machine/tool. Save this
document, refer to it often, and use it to instruct other operators.

Failure to read, understand and follow the instructions in this manual
may result in fire or serious personal injury—including amputation,
electrocution, or death.

The owner of this machine/tool is solely responsible for its safe use.
This responsibility includes but is not limited to proper installation in
a safe environment, personnel training and usage authorization,
proper inspection and maintenance, manual availability and compre­hension, application of safety devices, cutting/sanding/grinding tool
integrity, and the usage of personal protective equipment.

The manufacturer will not be held liable for injury or property damage
from negligence, improper training, machine modifications or misuse.

Some dust created by power sanding, sawing, grinding, drilling, and
other construction activities contains chemicals known to the State
of California to cause cancer, birth defects or other reproductive
harm. Some examples of these chemicals are:

• Lead from lead-based paints.

• Crystalline silica from bricks, cement and other masonry products.

• Arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies, depending on how often you
do this type of work. To reduce your exposure to these chemicals:
Work in a well ventilated area, and work with approved safety equip­ment, such as those dust masks that are specially designed to filter
out microscopic particles.

Machine Description

The T1243 Cross-Slide Rotary Table allows users
to perform milling operations up to 360° around a
fixed axis, as well as move up to 4" along both the
X and Y axes. Three handwheels control rotation
and table movement.

The T1243 can be mounted horizontally or verti­cally on a mill-drill table. The supplied T-bolts and
hold-down clamps are designed to work with mill­ing machine tables that have

7

⁄16" or 1⁄2 " T-slots.

Refer to the following figures and descriptions to
become familiar with the basic controls and com­ponents of this machine. Understanding these
items and how they work will help you understand
the rest of the manual and minimize your risk of
injury when operating this machine.

A. Y-Axis Handwheel w/Graduated Scale:

Moves table forward and backward when
handwheel is perpendicular to rotary table
handwheel (F) as shown; moves table side
to side on X-axis when handwheel is parallel
with rotary table handwheel. One full turn of
the handwheel moves the table 0.1".

on Y-axis when handwheel is perpendicular
to rotary table handwheel. One full turn of the
handwheel moves the table 0.1".

E. Ball Oilers: Are used to lubricate the rotary

table leadscrew and worm gear.

F. Rotary Table Handwheel w/Graduated

Scale: Rotates the table through a full 360°

rotation. One full rotation of the handwheel
turns the table 4°.

G. Rotary Table Locks: Lock the table in place.

This reduces the stress on the worm and
spur gear interface and helps ensure the
table does not change position during heavy
machining operations.

H. Rotary Table Degree Scale: Graduated in

whole degrees for rotational table positioning.

I. Horizontal Mounting Slot: Use to attach

T1243 to milling machine table with T-bolt.

J. Table Gib Adjustment Screws: Provide

adjustment for play in the table without caus­ing the slides to bind.

K. Cross Slide Gib Adjustment Screw (1 of

slide without causing the slides to bind.

SECTION 1: SAFETY

For Your Own Safety, Read Instruction

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

proper operation of the machine.

Safety Instructions for Machinery

OWNER’S MANUAL. Read and understand this

owner’s manual BEFORE using machine.

TRAINED OPERATORS ONLY. Untrained oper­ators have a higher risk of being hurt or killed.
Only allow trained/supervised people to use this
machine. When machine is not being used, dis­connect power, remove switch keys, or lock-out
machine to prevent unauthorized use—especially
around children. Make your workshop kid proof!

DANGEROUS ENVIRONMENTS. Do not use
machinery in areas that are wet, cluttered, or have
poor lighting. Operating machinery in these areas
greatly increases the risk of accidents and injury.

MENTAL ALERTNESS REQUIRED. Full mental
alertness is required for safe operation of machin­ery. Never operate under the influence of drugs or
alcohol, when tired, or when distracted.

ELECTRICAL EQUIPMENT INJURY RISKS. You
can be shocked, burned, or killed by touching live
electrical components or improperly grounded
machinery. To reduce this risk, only allow qualified
service personnel to do electrical installation or
repair work, and always disconnect power before
accessing or exposing electrical equipment.

DISCONNECT POWER FIRST.
nect machine from power supply BEFORE making
adjustments, changing tooling, or servicing machine.
This prevents an injury risk from unintended startup
or contact with live electrical components.

EYE PROTECTION. Always wear ANSI-approved
safety glasses or a face shield when operating or
observing machinery to reduce the risk of eye
injury or blindness from flying particles. Everyday
eyeglasses are NOT approved safety glasses.

Always discon-
