OPERATION
4.
After operations are completed, fill the fuel tank fully by
adding fuel through oil filler port (F) on the rear right side of
the machine.
Once the tank is filled up, do not try to supply additional
fuel.
For the cap opening and closing procedure, see "METH-
OD FOR OPENING AND CLOSING CAP WITH LOCK
(3-220)".
5.
After adding, tighten the fuel filler cap securely.
Fuel tank capacity: 300 ℓ
METHOD FOR CHECKING DEF LEVEL AND 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.
•
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.
NOTICE
•
Do not add DEF more than line F of sight gauge (5). 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 (5).
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, 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.
