NOTICE
i
As the corrosion and antifreeze concentration reduces with time,
carry out an annual check with a commercially available an-
tifreeze tester.
If the concentration is too low, either:
▪
drain part of the coolant and bring to the required frost
safety level by adding radiator protective fluid, or
▪
replace the entire filling of coolant (see section
).

Fuel
Fuel type
All types of diesel fuel that meet the minimum requirements of the following
specifications are suitable:
▪
Europe: EN 590
▪
UK: BS 2869 A1 / A2
▪
USA: ASTM D 975-09a 1-D S15
or
2-D S15
▪
USA: ASTM D 975-09a 1-D

(with a maximum HFRR value of 520 µm)
CAUTION
Danger of engine damage from low quality fuel.
The use of fuel that does not meet the specifications can lead to
engine damage.
▪
The use of fuel that does not meet specifications requires
approval by Motorenfabrik HATZ (main plant).
CAUTION
Danger of malfunctions due to old fuel.
When diesel fuel is stored in a fuel tank or canister for lengthy
periods, deposits may form on account of fuel aging. These de-
posits result in malfunctions due to clogged fuel filters and dam-
age to the injection system.
▪
Perform the prescribed storage steps in machines that will
be out of use for more than three months (see section
).
▪
Only refuel with fresh diesel fuel such as can be obtained
from filling stations.
