Before shipment, the pumps are carefully packed inside a cardboard box. During transport and storage of the equipment, pay
attention to the direction indicated on the box. Upon receipt, check that the packaging is not damaged and store the pump in
a dry place.
14. PRECAUTIONS FOR USE
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).
ATTENTION: The warnings on risks using a lubricant pump implies must be carefully read. The user must be
familiar with operation through the Operation and Maintenance Manual.
14.1. LUBRICANTS
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 OmegaPUMP 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.
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 0 grade.
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 (2006/42 CE - 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 change of the cartridge. → Protection from direct or indirect contact with the
lubricant must be ensured by the user of the machine. (See the PPE regulation on proper use according to regulations in force).
•
Preload springs in the control cylinder and any in the reservoir.
•
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).
