INTRODUCTION
The GraverMach AT is designed to assist the metal,
jewelry, stone, wood, or ivory artisans in creating their
unique masterpiece(s).
The GraverMach AT coupled with a GRS handpiece creates an
air-powered hammer system. The machine creates the air pulses
and the handpiece turns those air pulses into a mechanical
hammer action. How the handpiece hammers is dependent upon
the settings of the GraverMach AT. Settings include: strokes
per minute, air pressure, bias, handpiece, and range of power
control by hand or foot. These settings allow the artisan an
efficient means to fine tune the system to their needs. In addition,
the GraverMach AT offers an auxiliary air system for a rotary
handpiece or other air tools.
The GraverMach AT Operation and Maintenance Manual has
been prepared for you so that you can familiarize yourself with
this machine. Please read this document thoroughly before use.

IMPORTANT NOTICE
When you unpack your new GraverMach AT notice the screw
protruding from the bottom of the machine (Fig. 1-V). This screw
is holding the motor mount assembly to protect it from damage
during shipping. You will need to remove the
screw with a 7/16" wrench or socket, or an adjustable
end wrench before placement and use.
Store the screw and washer by inserting
them into the rubber grommet located on
the back of the machine (Fig. 1-R).
Shown in the illustration to the right.
Please note, if you are going to
transport this machine OR ship it,
YOU MUST replace and tighten the screw to
prevent damage to the motor mount assembly.
Never lay the machine on its side and turn it on. ALWAYS
use the machine in a vertical position. The rotary valve
is lubricated by air passing through it. DO NOT the run
electrical system unless the air supply is turned on and
adequate air pressure is present.
