HATZ Diesel 1B50W - Manual (Page 25)

5.4. Maintenance every 500
operating hours
5.4.1. Renewing fuel filter
The maintenance intervals for the fuel pump
filter are dependent upon the purity of the diesel
oil being used and, if necessary, may have to be
reduced to 250 hours.
When working on the fuel system, do
not expose it to naked flames; do not
smoke.
Important !
Keep the entire area clean so that no dirt
reaches the fuel. Fuel particles may damage
the injection system.
