SECTION V MAINTENANCE
Assemble the new parts or those disassembled reversing the order of
disassembly.
Checking the pump’s normal operation
Rotate ignition key to position 1 and make sure by way of listening the
pump is fuctioning properly. The pump will stop pulsating if the supply
pressure exceeds the prescribed limits.
In addition, check for any fuel leaks.
Air bleeding
Air-bleeding of the fuel pump should be done with the engine on and
ignition key in position 1.
This operation must be performed before bleeding the air out of the fuel
filter and the injection pump.

Fuel
We recommend that you use only commercial brands of diesel fuel which
have a sulphur content of 0.5% or less.
If you use a fuel with a sulphur content that exceeds 0.5%, the oil change intervals
indicated in this manual must be halved.
