Caution should be used when dispensing DEF near
an engine that has recently been running. Spilling
DEF onto hot components may cause the release of
ammonia vapors. Do not breathe ammonia vapors.
Do not clean up any spills with bleach.
Ensure that the DEF tank is full before starting work.
1.
Before filling the DEF tank, ensure that the DEF
lines have been purged. Purging of the DEF lines
will take place, after the engine has stopped. Only
after purging the DEF lines should the DEF tank
be filled. For more information on the time taken
for purging the DEF lines, refer to this Operation
and Maintenance Manual, “Battery Disconnect
Switch”.
2.
Ensure that the DEF cap (1) and the surrounding
area is clean and free from dirt. Ensure that all
equipment use in filling the tank is clean and free
from dirt.
3.
Remove the DEF cap from the tank.
4.
Fill the tank with the required amount of DEF.
Ensure that dirt is not introduced into the tank
during filling. Do not over fill the tank. The DEF will
require room for expansion.
Note:
Always fill the DEF tank on level ground. Cold
weather can affect DEF, refer to this Operation and
Maintenance Manual, “Diesel Exhaust Fluid in cold
Weather” for more information.
5.
The opening on the DEF tank (2) is a special
diameter. Ensure that the correct nozzle is used
when filling the DEF tank.
Note:
At key on the DEF level gauge will show the
last known DEF level and will transition to the new
DEF level value.
6.
Install the DEF cap. Check visually the DEF tank
for leakage.
