ATTENTION
Danger of machine damage!
Even filling in small amounts of other liquids leads to great damage to the SCR
exhaust after-treatment system. No accommodation will be granted for such damage.
– Utmost cleanliness must be ensured when filling up AdBlue®.
– The AdBlue® tank may be filled with AdBlue® only, do not fill in water or other
liquids. A sensor in AdBlue® tank permanently measures the quality (urea con-
centration). If the quality is not sufficient, the diesel engine reduces its output, the
machine is no longer ready for operation.
