TEUPEN LEO 15 GT, Translation Of The Original Operating Instructions

Page: 193 / 208

5.4. Maintenance every 500
operating hours
5.4.1. Renewing fuel filter
The maintenance intervals for the fuel 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.
Model with double fuel filter system
49
This system consists of a maintenance-free
external filter „1“ (Fig. 49) and a replaceable-
cartridge filter which is installed in the tank
(Fig. 50). The advantage of this system consists
in retaining dirt particles which might get into
the fuel system on filter replacement, upstream
of the following external filter, so that they can-
not endanger the injection system.
Important !
This external filter must not be replaced. Only
replace the fuel filter installed in the tank !
