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.

We are proud to offer this manual with your new

machine! We've made every effort to be exact

with the instructions, specifications, drawings, and

photographs of the machine we used when writ-

ing this manual. However, sometimes errors do

happen and we apologize for them.

Also, owing to our policy of continuous improve-

ment, your machine may not exactly match

the manual. If you find this to be the case, and

the difference between the manual and machine

leaves you in doubt, immediately call our techni-

For your convenience, we always keep current

Grizzly manuals and most updates available on

our website at www.grizzly.com. Any updates to

your machine will be reflected in these documents

as soon as they are complete. Visit our site often

to check for the latest updates!

The vertical mill is used to remove material from

metal workpieces to form shapes. Tooling is

inserted into the spindle of the head, which can

be positioned in nearly any configuration above

the table and workpiece.

During most operations, the tooling rotates in the

spindle above the workpiece while the operator

moves the workpiece, which is clamped to the

table, in any combination of three paths of table

movement—longitudinal (X-axis), cross (Y-axis),

and vertical (Z-axis). The range of vertical move-

ment for the table is greater than that of the head

and spindle. However some operations, such as

drilling or tapping, are better accomplished with

vertical spindle movement using the coarse or

fine downfeed controls.

The operator selects available spindle speeds by

configuring the two V-belts across the motor, idler,

and spindle pulleys.

The Model G3103 has a longitudinal power

feed for consistent powered table movement

with adjustable limit stops for a preset range of

motion.
