MACHINE OPERATIONS AND CONTROLS
METHOD FOR CHECKING DEF LEVEL, 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 during opening or refilling.
•
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.
•
BIB container (10 ℓ) weighs 11 kg.
Before putting it on the DEF tank filler port cover, put BIB container onto the step behind the DEF
tank first. Then, climb on the top of the track from the front of machine, and move BIB container to
the top of the DEF tank filler port cover.
•
The DEF supply hose is installed to this machine.
The hose is in a plastic bag. After using the hose, put it into the bag and close it to store.
It prevents dust from sticking to the hose. In addition, it also prevents the machine from getting
dirty and being corroded by the fluid from the hose.
•
When the DEF supply hose gets dirty, wash it in distilled water, deionized water or DEF.
NOTICE
•
Do not add DEF more than line F of sight gauge (3). DEF may leak through the cap or the breather.
When the ambient temperature is low and DEF may freeze, do not add it more than line (8) of sight
gauge (3).
Be careful of the DEF line to be added when performing operations on a slope or traveling on a
rough ground. When the remaining DEF level is low, a warning may be displayed or the engine pow-
er is limited 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, seal it, and
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 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.
