14. OPERATING HAZARDS
It is necessary to read and understand the possible hazards and risks involved when using a lubrication pump.
The operator must fully understand the hazards explained in this manual.
Electrical Power
No maintenance must be performed on the unit without having detached and isolated the power supply
and ensuring that it cannot be reconnected for the duration of the maintenance task. Always remember
to ensure that equipment is properly earthed.
Flammable substances.
Mineral oils generally used in lubrication systems are not normally flammable. However, it is desirable to
avoid contact with extremely hot substances or naked flames. Ensure that the machine that the
lubrication system is installed onto contains the necessary fire extinguishing devices.
Pneumatic & Hydraulic Pressure
Before any maintenance or connection task, ensure that all pressure has been properly bled from the
system. Residual pneumatic or hydraulic pressure can cause the release of undesired spurts of liquid,
which may hit the operator. Always wear safety glasses and glove when working with pneumatic and
hydraulic systems.
Noise and Vibration
The Locopump pump does not produce excessive vibration or noise (less than 70 dB(A) )
15. PRECAUTIONS
Verification of compliance with essential safety requirements and machine Directive dispositions has been
carried out filling in checking lists provided and contained in the technical file.
Dropsa used two kind of checking lists:
•
The list of hazards (according to the EN 1050 as it refers to EN 292).
•
Enforcement of the essential safety requests (machine Directive – annex 1, part 1).
Residual but acceptable hazards are described below:
•
During maintenance operations, spurts of lubricant at low pressure could occur. (Said operations have to
be carried out using the proper health and safety regulations).
•
Contact with lubricant. See dispositions for proper health and safety regulations.
•
Pre-loaded springs positioned inside the control cylinder and reservoir.
•
Use of incompatible/non-permissible fluids. Compatible lubricant characteristics has been shown in this
manual and can be found on the label stick onto the machine. In the event of doubts, contact the Dropsa
technical centre.
•
Electrical and hydraulic protection should be provided by users.
•
Monitor electric contacts to ensure the pump is working during machine operations. In case of short-
circuits the machine can be reset and restart by user whilst the lubrication pump restarts automatically.
•
Do not use alcohol for machine cleaning.
Examples of incompatible/non-permissible Fluids.
