OPERATION
REMARK
•
It is recommended to use a nozzle having a diameter and
a length specified by ISO 22241-4 and an auto stop func-
tion to add DEF. When the specified nozzle is used, the
magnet installed inside the filler port of the tank cancels
the wrong fluid addition prevention device, and you can
add DEF. This mechanism prevents addition of DEF into
the fuel tank, addition of fuel into DEF tank, and spill of
DEF from the filler port.
•
When using a nozzle which is not conformed to ISO
22241-4, hold it in your hand and add DEF carefully while
checking the sight gauge.
•
Add only DEF in clearly marked DEF tanks that have the blue cap.
•
When the key is turned to ON position soon after the DEF is added, the DEF level gauge (1) on the ma-
chine monitor may not follow promptly.
