2 OPERATION
– 64 – – 65 –
WARNING
• DEF on the skin may cause inflammation in some people, so contaminated
clothes, shoes, etc., should be taken off and washed in cold or warm water. If
there are any changes in appearance or pain, promptly seek medical help.
• If the DEF is accidentally swallowed, rinse out your mouth well with water, and
promptly seek medical help.
• If the DEF gets in your eyes, rinse it out immediately in clean water for several
minutes, then promptly seek medical help.
• Wear protective glasses when there is a danger of the DEF splattering. Wear
rubber gloves if work requires you to come into contact with the DEF.
• Do not put anything other than DEF into the DEF tank. Diesel, gasoline, etc., in
particular may cause fires. Moreover, putting additives in the tank may lead to
generation of toxic gases.
• Opening the DEF tank cap may release toxic ammonia gas. When opening the
cap or filling the tank, keep your face away from the filler port.
• If the DEF is spilled, promptly wipe it clean and wash with water. Neglecting
to do so may lead to toxic gases or corrosive substances being given off.
CAUTION
• Put AUS32 or ISO (International Organization for Standardization) ISO22241-1
certified DEF in the DEF tank.
Using anything else may cause breakdowns in the DEF SCR system.
• Never modify the DEF SCR system.
• The machine will not be able to function properly, and it will not satisfy exhaust
gas emissions standards. It may also damage the machine.
• The machine will continue running for several minutes after the engine starter
switch has been turned off, but this is to pump the DEF left in the pipes, injector,
and supply pump back into the DEF tank, and it is not abnormal.
Moreover, do not pull out the battery cord while the system is still running.
• Keep the DEF tank topped up by refilling it at the right time.
• If the engine has not been turned on for one year or more, replace the DEF before
starting it. Starting the engine without doing so may cause the SCR system to
break down.
• Check the DEF SCR system to make sure there are no abnormalities after
starting the engine.
If there is something wrong with the DEF SCR system, stop the engine and
restart it.
