Fill up fuel tank
With the machine cold:
1. Pour fuel (fuel oil EL,
or Diesel oil DIN 51 603)
into the fuel tank.
Bio-Diesel can be used, see
notes in chapter 1).
The fuel must be free from con-
tamination.
Tank capacity see chapter 9.4
Technical data.
NOTE!
At temperatures below 8° C, the fuel
oil begins to solidify (paraffin precip-
itation). This can lead to difficulties
in starting the burner. Before the
winter period either add a solidifica-
tion point / flow improver (available
from the fuel oil trade) to the fuel or
use winter diesel fuel.

3.7 Antiscale
The Nilfisk Alto Antiscale dosing
system is set by the factory.
To adjust the water hardness we
recommend that the inlet water
is tested accordingly.
Use the schematic to find the
right dosage of No Scale/anti
stone and water, and add the
mixture to the antiscale tank.
