13. HANDLING AND TRANSPORTATION
Prior to shipping, the equipment is carefully packed in cardboard package. During transportation and storage, always
maintain the pump the right way up as indicated on the box. On receipt check that package has not been damaged.
Then, storage the machine in a dry location.
No particular precautions are required except as noted on the package itself.
Handling must be effected by at least two persons.
!
Lift the unit with taking account of the right way up indicated on the cardboard carton
!
The machine components can withstand temperatures, during storage, from -20 to +50°C; however, in order
to avoid damage, starting of the machine should occur at a minimum temperature of -5°C.
14. OPERATING HAZARDS
It is necessary to read and understand the possible hazards and risks involved when using centralized
lubrication systems. The operator must fully understand the hazards explained in this manual.
An improper use of centralized lubrication systems may cause damages due to an excessive or
inadequate lubrication of the points to which it is connected.
It is always necessary to comply with the accident prevention laws and the environmental regulations in
force in the area where the centralized lubrication system is used.
Power supply
Any type of intervention must not be carried out before unplugging the machine from power supply. Make sure that
no one can start it up again during the intervention.
All the installed electric and electronic equipment, reservoirs and basic components must be grounded.
Flammability
The lubricant generally used in lubrication systems is not normally flammable. However, it is advised to avoid contact
with extremely hot substances or naked flames.
Pressure
Prior to any intervention, check the absence of residual pressure in any branch of the lubricant circuit as it may cause
oil sprays when disassembling components or fittings.
Noise
Pump does not produce excessive noise, less than 70 dB(A) .
