START-UP

Before commissioning:
- Make sure you have read and understood all the rules and warnings in the "user and maintenance"
document for each type of diesel pump.
- Read the chapter and rules on safety in this manual (page 6)!
The first commissioning operations must be performed by specialized technicians. Unauthorized
ATTENTION
operations on the engine could lead to the forfeiture of the warranty.
Do not start up the motor if the system where the diesel pump is installed has not been completed and is not fully up to
standard.
5.1 Preliminary operations and checks before commissioning
Always follow all the instructions below before commissioning in any of these situations:
- After installation
- After a complete overhaul.
- When supplementary maintenance has been carried out on any of the systems and/or circuits of the diesel pump.
- when the diesel pump has been inactive for a long period.
The various systems should be checked for leaks and/or faults before commissioning and after initial start-up:
- water cooling circuit (when the engine is fitted with one).
- lubricating oil circuit.
- fuel circuit.
- Check the hydraulic system.
- Perform a general inspection of the motor.
- Check the cabling of the motor and electric panel.
- check the battery.
During all the required checks described in the following paragraphs, make sure that the engine cannot
start up accidentally. Set the key-operated selector switch to the "0" position and make sure the batteries
are disconnected ( see the "Batteries" section for the correct procedure).
5.1.1 Cooling water circuit (for water-cooled engines only)
- If necessary, fill up the cooling circuit (for engines with this feature), adding the correct quantity of antifreeze fluid to the water
according to the instructions contained in the relevant engine documentation.
- When filling up with cooling water for the first time, open the air bleed valves found on the engine until all the air has been bled
from the circuit. Fill the circuit (engine and radiator) slowly to prevent the formation of air pockets.
- Check the circuit carefully to make sure that there are no leaks anywhere.
- After running the system for a short while, check to see whether the water level in the radiator has dropped, since air pockets
may have remained in the system during the first fill-up. Top up with water as necessary.
5.1.2 Lubricating oil circuit
The engine comes fully charged with oil; if you need to change the oil proceed as follows:
- As regards the type of oil used, which depends also on the ambient temperature, and the amount of oil needed by the engine,
refer to the instructions provided in the relevant engine documentation.
- Drain any previous oil residues from the sump.
- Make sure the filters are clean; if necessary, replace the filters together with the related gaskets.
- Fill the lubricating oil sump up to the top notch on the dipstick, without exceeding it.
- While the engine is still cool after running for a short while, check the oil level again and top up as needed.
- Check the circuit carefully to make sure that there are no leaks anywhere.
Dispose of used oil and any rags soaked with oil in compliance with the regulations in force!
5.1.3 Fuel circuit
- Make sure the filters are clean and, if necessary, replace them.
- Fill the fuel tank with automotive diesel engine gas oil in compliance with the directions contained in the engine operator's
handbook.
- Check the circuit carefully to make sure that there are no leaks anywhere.
- Check the position of the fuel on-off valves.
For EN12845:2004 compliant fire pumps, the tanks must be kept full to ensure continuous operation for a minimum
number of hours in relation to the class of risk of the system.
