14. PRECAUTIONS FOR USE
:
ATTENTION
familiar with operation through the Operation and Maintenance Manual.
Electrical power supply
No operations must be carried out on the machine before disconnecting it from the electrical power supply and ascertaining that
no-one can reconnect it during the operation. All installed equipment (electric and electronic) must be connected to the earthing
system.
Flammability
The lubricant generally used in the lubrication circuits is not inflammable fluid. However, it is imperative to take all necessary
steps to prevent it from coming into contact with very hot parts or naked flames.
Valve
Before any operation, check for the absence of any residual pressure in all branches of the lubricant circuit, that could cause
spurts of oil in the event that fittings or components are disassembled.
Noise
The equipment does not emit noise exceeding 70 dB (A).
14.1 LUBRICANTS
NOTE: The pump is designed to work with maximum NLGI 2 grade lubricants.
Use NBR gasket compatible lubricants.
Any residual lubricant inside that was used for assembly and testing is NLGI 2 grade.
A table is shown that compares the NLGI (National Lubricating Grease Institute) and ASTM
(American Society for Testing and Materials) categories for greases, limitedly to the values
that involve the PoliPUMP pump.
For further information on the technical characteristics and the safety measures to adopt,
see the Product Safety Data Sheet (Directive 93/112/EEC) related to the type of lubricant
selected and supplied by the manufacturer.
15. CONTRAINDICATIONS OF USE
Compliance with the essential safety requirements and machine directive provisions has been checked through the completion
of check lists already drafted and contained in the technical file
Three types of lists were used:
Compliance with essential safety requirements (Machine Directive).
Risk assessment (EN ISO 12100).
Electrical safety requirements (EN 60204-1).
The hazards that have not been entirely eliminated, but that have been deemed acceptable, are listed below:
During the maintenance phase, low pressure spurts of lubricant are possible. (For this reason, maintenance operations
must be carried out using suitable PPE).
Contact with lubricant during maintenance or filling the reservoir. Protection from direct or indirect contact with the
lubricant must be ensured by the user of the machine. (See the regulation on proper use according to applicable
regulations).
Impact and crushing. Moving parts are all enclosed and the designation of such danger has been indicated at the access
point.
Electrocution. This can occur only in the event of serious negligence by the user who, however, is qualified.
Use of unsuitable lubricant. The characteristics of the lubricant are indicated both on the pump and in this Operation
and maintenance manual (in the event of any doubt, contact the Dropsa S.p.A. Technical Office):
Lubricants with abrasive additives
Lubricants with silicon additives
Petrol – solvents – flammable liquids
Corrosive products
Water
Food substances
