shutting the engine down.

CAUTION

0000002en

NEVER permit anyone to operate the
engine or driven machine without proper
training.

• Read and understand this Operation

Manual before you operate the
machine to ensure that you follow safe
operating practices and maintenance
procedures.

• Machine safety signs and labels are

additional reminders for safe operating
and maintenance techniques.

• See your authorized Yanmar industrial

additional training.

DANGER

0000002en

SCALD HAZARD!

• NEVER remove the radiator cap if the

engine is hot. Steam and hot engine
coolant will spurt out and seriously
burn you. Allow the engine to cool
down before you attempt to remove
the radiator cap.

• Securely tighten the radiator cap after

you check the radiator. Steam can
spurt out during engine operation if
the cap is loose.

• ALWAYS check the level of engine

coolant by observing the reserve tank.

• Failure to comply will result in death or

serious injury.
