METHOD FOR CHECKING DEF LEVEL AND ADDING DEF
• Do not put fluid other than DEF into DEF tank.
• When opening the cap of DEF tank of the machine, the ammonia vapor may escape. Keep your face
away from the filler port.
• Foreign materials in the DEF system or urea deposits caused by precipitation of urea may hinder
operation of the devices. Before removing the filler cap, wipe off the dirt from around the filler port.
Before inserting the filler nozzle into the filler port, wipe off dirt from it.
• If DEF is spilled, immediately wipe and wash the area with water. If spilled DEF is left unattended
and the area is not washed and cleaned, it can cause corrosion to the contaminated area and emit
toxic gas.
