caution. When carrying out the operation, observe the safety Standards in force with regard
to safety at work.
DANGER Do not disassemble, transport or re-assemble the head with tools fitted in

4 Safety rules
4 SAFETY RULES
• Before starting the tool machine, make sure that the head is correctly connected to the
machine and, consequently, that there is no risk of it releasing and falling off.
• Wear always industrial safety gloves when handling. Be sure that no cutting tools are
in the spindles. Don’t power up the head while carrying out service. Disassemble the
multispindle head, as the sharp parts may cut or injure the personnel.
• Don’t touch the head when it is moving. Any adjustments and interventions must be carried
out when the machine is inactive and in absolute safe conditions for the operator.
• The operating machine on which the MPA head is fitted, must be manufactured in
compliance with current safety Standards. All operator safety guards must be correctly fitted
and efficient and approved according to Machinery Directive 2006/42/EC (ex 98/37/EC).
The design of these safety guards is under the sole responsibility of the Manufacturer of
the machine on which the head is fitted; safety parameters must be cheched exclusively
by the factory manager where the head is used.
• Suitable clothing for workshop jobs must always be worn when using the MPA head.
It is therefore forbidden to wear ties, necklaces and any other non-adhering clothes or
accessories that may create a hazard.
The safety at work Standard in force must be complied with.
• During cleaning operations, especially when compressed air is being used, proceed with
caution and wear safety goggles or other suitable means of protection.
• The maximum rotation speed or the maximum spindle torque must not be exceeded (see
data published on the official website www.m-p-a.it).
Keep always transmission and rotation direction ratio under control; the values are shown
both on the nameplate and on the attached technical drawing.
• The use manual must always be kept handly where the head is being used. You also
must comply with the precautions in this manual, the general and local Standards in force
regarding accident prevention, and environmental protection.
DANGER If tools involving consistent rotating cams are used, operate at rotation speeds
such to prevent the centrifugal force created by the cams from compromising the
integrity of the spindle.
MPA engineering department is always at your complete disposal for any
advice on ideal operating conditions.

ADJUSTABLE MULTISPINDLE HEADS
4 Safety rules
• The forward movement speed of the tool must be adjusted so that no excessive axial
force is put on the tool, which could cause it to collapse with the consequent hazardous
cast-off of chips of material.
• Check the conditions and state signs of wear on the tool.
• Any anomalies on the head may cause serious damages and reduce significantly the life-
time and precision of the head. When in doubt, always contact MPA.
• The normal temperature of the head while it is working must not tendentiously exceed
60°C. Only during the first 100 hours of use the temperature can increase its maximum
value by about 25%.
