15.2 Filling the DEF Tank
Requirements
■ Machine level with the ground
■ Remote switch disconnected from the remote run terminal
■ Fresh Diesel Exhaust Fluid (DEF)—also known as Aqueous Urea Solution 32%
(AUS32)—manufactured to the standards of ISO 22241.
Background
The DEF refilling interface on this machine meets ISO 22241-4. The inlet includes
a magnetic ring that opens filler nozzles that meet the ISO 22241-4 standard. This
system also allows for automatic shut-off.
Notices
■ Do not put Diesel fuel or any other liquid besides DEF into the DEF tank.
■ The DEF freezes (crystallizes) at 11°F (-12°C). Do not overfill the DEF tank.
DEF expands when frozen. Expanding DEF can cause machine damage.
■ DEF may be corrosive on certain materials (copper, brass). Clean up any spilled
DEF immediately.
