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 which are 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.
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.
Indicates a potentially hazardous situation which, if not avoided,
COULD result in death or serious injury.
Indicates an imminently hazardous situation which, if not avoided,
WILL result in death or serious injury.
This symbol is used to alert the user to useful information about
proper operation of the machine.

Additional Safety Instructions for Mini Mill
No list of safety guidelines can be complete.
Every shop environment is different. Always
consider safety first, as it applies to your
individual working conditions. Use this and
other machinery with caution and respect.
Failure to do so could result in serious per-
sonal injury, damage to equipment, or poor
work results.
Like all machines there is danger associ-
ated with the Model G8689. Accidents are
frequently caused by lack of familiarity or
failure to pay attention. Use this machine
with respect and caution to lessen the pos-
sibility of operator injury. If normal safety
precautions are overlooked or ignored, seri-
ous personal injury may occur.
