REMARK
• If the breather hole in the cap is clogged, the pressure inside the tank will go down and this may cause fuel
to stop flowing. To prevent this, clean the breather hole from time to time.
• To prevent air from being sucked into the engine, always pay careful attention to the fuel level in the tank.
• If fuel is added too much, the fuel may leak due to the expansion caused by temperature increase.
When adding fuel, be careful not to add it too much.
METHOD FOR CHECKING DEF LEVEL AND ADDING DEF

WARNING
• Do not put any 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 entered in DEF system or urea deposit by urea separation may disturb the opera-
tion of the system. 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 off and clean 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 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.
