MACHINE OPERATIONS AND CONTROLS
NOTICE
•
Do not add DEF more than line F of sight gauge (4). DEF may leak through the breather. When the
ambient temperature is low and DEF may freeze, do not add it more than line (9) of sight gauge (4).
Be careful of the DEF line to be added when performing operations on a slope or travelling 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 unspecified container, foreign material may mix in it and toxic gas or corrosive
substance may be produced by chemical reactions. When adding DEF, do not transfer it to another
container.
•
Do not use a funnel when to add DEF. The strainer may be broken.
•
When using a portable DEF refill container, use up DEF each time. If any of DEF is left, remove for-
eign material, if there is any.
•
Do not wash the adding 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 audible alert sounds to warn the abnormality. In this case, ask your Komatsu
distributor for draining of the wrong fluid and for inspection. DEF injector and/or DEF pump may
need to be replaced.
