3-14 Urea(SCR) System (C60-80D, Doosan Engine)
Do not add urea solution if the tank is full(recommended
amount is 20 L). Overfilling the tank may cause frosting in
winter and the urea solution will expand and damage the
tank as well as the SCR system.
Make sure that there is NO foreign substance while filling
the urea solution tank, including any additive and water.
Such foreign substance will gravely affect the forklift per-
formance and may cause a malfunction.
Make sure that the urea solution meets the specifications
of ISO 22241. Urea solution of poor quality will gravely
affect the forklift performance and may cause a malfunc-
tion.
• Turn the cap of the tank clockwise and close it completely. Wipe
the area around the cap with a clean cloth after filling the tank.
Any remaining urea solution will contaminate the forklift.
(Consumption of urea solution may vary per driving practices and
conditions.)
