REMARK
• White smoke may be discharged for a short time im-
mediately after the engine is started or during the af-
tertreatment devices regeneration in cold season, but
this is not a failure.
• The smell of the exhaust gas is different from that of
the conventional diesel engine because of the exhaust
gas filtering function.

After the engine starts, wait for the engine oil pressure caution lamp to go out. Do not perform the work
equipment operation or travel while the engine oil pressure caution lamp is lit.
REMARK
If the engine oil pressure caution lamp does not go out in 4 to 5 seconds, stop the engine immediately.
Check the oil level, oil leakage, etc. and take proper measures.
