MACHINE OPERATIONS AND CONTROLS
4.
Open up the cover (2) at the right side of the machine, turn
the cap of filler port (3) counterclockwise.
The cap of filler port is opened.
The cap of DEF tank is blue as required by the emission
regulations.
5.
While watching the sight gauge (4), add DEF through the
filler port until float (5) reaches the line F (6).
Line (7) in the sight gauge indicates approximately 10 ℓ be-
low the line F, and the line (8) indicates approximately 20 ℓ
below the line F.
Line (9) is the upper limit line for adding when DEF may
freeze in cold weather.

After adding, align the claw (10) of the cap with groove (11)
of the filler port and close the cap securely by turning it
clockwise by 90 °.
REMARK
• It is recommended to use a nozzle having a diameter and a length specified by ISO 22241-4 and an auto
stop function 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 DEF to the DEF tank indicated by blue cap.
