Determine the soot rating with a soot pump (1)
and soot rating reference scale. The figure
should not exceed "1". Otherwise, open the air
flap (Fig.G.07) a little and repeat the measure-
ment. Repeat the procedure until the specified
value is obtained.

The CO2 content in the exhaust, the intake
and exhaust temperature are determined.
This can be done with conventional meters
or, as in Fig. G.08, with an electronic meter
like the TESTO 325 (4), which measures
and displays all relevant data.
If the measured value is too low, close the
air flap (Fig.G.06) a little and check the soot
rating and Co2 content again.

Service time setting:
Switch off machine with S1. install a jumper on X5 between pin 3 and 5. Switch on machine
(cold water mode). With the temperature setting knob it is now possible to set a new service
interval. The reading is done by the LED’s (4,5,6,7 and 8), where (4) is 100 hours, 4+5 is 200
hours and so on, up to 500 hours when all LED’s are on. If setting is not changed for 3 sec.,
the setting is saved. This can be seen when the chosen LED’s are flashing. Machine must now
be switched off, and the jumper removed from X5. Default service setting from factory is 200
hours.
