Flashing codes
The indicator (5) only flashes during operation if a problem arises in connec-
tion with the exhaust gas return system. This includes a dirty air filter. This
can be identified by the following flash code of the indicator (5):
▪ 7 times short flash (approx. 0.5seconds) and 1 long flash (approx.
1.5seconds).
▪ The flash code indicates that the air filter must be cleaned or changed
(see chapter 8.2.12 Checking and cleaning the air filter cartridge, page
81).
▪ If a different flash code appears, please contact the nearest Hatz service.
NOTICE
If the electronics indicate a problem continuously for more than
15 minutes without interruption (flash code - indicator 5), the en-
gine switches off automatically.
▪ If the problem persists, the engine can be started but only
for another 15 minutes.
▪ If necessary, contact your nearest HATZ service station.
