OPERATION
NOTICE
•
Do not add DEF more than the line F of sight gauge (4). DEF may leak through the breather. When
DEF may freeze in cold weather, do not add it more than the line (9) of sight gauge (4).
Be careful of the DEF line when performing operations on a slope or traveling on a rough ground.
When the remaining DEF level is low, it may become the warning level if DEF pump sucks air or if
DEF level suddenly drops.
•
If DEF is stored in another container, foreign material may be mixed in it and toxic gas or corrosive
substance may be produced by chemical reactions. When adding DEF, do not transfer it to another
container.
•
If you use a funnel to add DEF, the strainer may be broken. Do not use a funnel.
•
When using a portable refill container, use it up each time. If any of it is left, completely seal it up.
Remove foreign material, if there is any.
•
Do not wash the supply nozzle in city water. Minerals may clog the devices.
•
Do not dilute DEF with water.
•
If you add fluid other than DEF (diesel fuel, low concentration DEF, etc.) by mistake, the caution
lamp lights up and the alarm buzzer sounds to warn the abnormality. In this case, ask your Komatsu
distributor for draining of the wrong fluid and inspection. DEF injector and/or DEF pump may need
to be replaced.
