CHAPTER 1
INTRODUCTION
1.1 PURPOSE AND CONTENT OF THE
MANUAL
The purpose of this manual is to provide the User with all
necessary information to use the machine properly in a
safe and autonomous way. It contains information about

Technicians qualified for the machine maintenance. The
operators must not carry out operations assigned to
qualified technicians. Minuteman declines liability for
any damage arising from notobserving this prohibition.
1.3 HOW TO KEEP THIS MANUAL
The User and Maintenance Manual must be kept near the
machine, inside an adequate case, far from liquids and
other substances that can cause damage to it.

1-2
1.4 IDENTIFICATION DATA
The Machine Model and Serial Number are marked on the
plate on the frame (battery side) and can be read from
the outside (1,Figure 1-1).
This information is useful when requiring machine
replacement parts. Use the following table to write down
the machine identification data for any further
reference.
1.5 OTHER REFERENCE MANUALS

CHAPTER 2
SAFETY - ACCIDENT PREVENTION
The following symbols indicate potentially dangerous
situations. Always read carefully this information and take
the necessary precautions to protect people and objects.
Cooperation between the Operator and the machine is
critical. No accident prevention program is effective
without the total cooperation of the person responsible for
the machine operation. Most of the accidents that may
occur in a factory, while working or transferring, are
caused by the failure to comply with the simplest prudence
rules. A careful and prudent user is the best guarantee
against accidents and is the prerequisite to carry out the
prevention program.
2.1 SYMBOLS
