Note: Personnel must use protective devices, garments and tools in compliance with current standards with regard to the
location and the use of the pump both during work as well as during maintenance operations.
ATTENTION: The warnings about the risks involved in using a pump for lubricants must be read. The user must
understand its operation using the user and maintenance manual.
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
Before each operation, make sure there in every branch of the lubrication circuit that there is no residual pressure that could
cause oil to spray when disassembling fittings or components.
After long periods of inactivity, check the seal of all the parts subject to pressure.
Do not subject the fittings, pipes and pressurised parts to violent impacts.
Damaged flexible pipes or fittings are DANGEROUS and must be replaced.
Only original spare parts should be used.
Noise
Under normal operating conditions, noise emission does not exceed 70 dB "A" at a distance of 1 metre (39.3 inches) from the
pump.
NOTE:
The pump has been designed to operate with Sealant.
Always use sealants compatible with NBR (Buna) Rubber seals.
Any residual sealants found on new units is residual sealant during the testing and assembly of the pump.
A comparison table is provided between the classification of NLGI lubricants (National
Lubricating Grease Institute) and the ASTM classification (American Society for Testing and
Materials) for greases for the values that concern the pump.
For further information about the technical specifications and the safety measures to adopt,
refer to the product safety sheet (Directive 93/112/EEC) relative to the type of lubricant
selected and supplied by the manufacturer.
14. CLEANING
It is necessary to remove periodically dust from pump avoiding the spread in the air. For this operation refers to Safety Officer.
15. TRAINING
Personnel assigned to installation, electrical connections and ordinary and special maintenance of the pump, must have at least
8 hours of specific training by an appropriate organism on equipment for explosive atmospheres caused by the inflammable
gases and combustible dusts.
