DRO Components

Model G0768Z features a magnetically mounted

DRO (see Figure 1) for X-axis (cross slide) and

Z-axis (carriage) travel.

Note: When placing the DRO, locate all cables so

they do not interfere with machine operation and

cannot be pinched by moving components.

Figure 1. DRO magnetically mounted on lathe

headstock.

The X-axis and Z-axis scales are attached to

the cross slide and bed (respectively). Shielded

cables run from each sensor to plugs on the back

of the DRO (see Figure 2). The DRO connects

to a regular 110V power supply with a dedicated

power cord using a NEMA 1-15 plug.

Digital Readout

A. DRO displays current position of X-axis and

Z-axis in hundredths of a millimeter or thou-

sandths of an inch. (Included Y-axis display

line is not used on G0768Z.)

B. "X" value displays total X-axis travel from

zero along cross slide.

C. "Z" value displays total Z-axis travel from

zero along lathe bed.

D. In/MM button allows users to toggle

measurement display in either inches or

millimeters.

E. ZERO buttons reset values at any point along

the axis to 0.00.

F. Green light indicates inches or millimeters.

G. Magnetic mount.

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 compre-

hension, 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 equip-

ment, such as those dust masks that are specially designed to filter

out microscopic particles.
