ADJUSTABLE MULTISPINDLE HEADS

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 006/4/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.
