Stay away from rotating parts during
operation.
* Otherwise you may get caught in the rotating
parts and seriously injured.
Adjust the belt tension properly in
accordance with the procedures
recommended by MHIET.
* Otherwise, the service life of the alternator,
bearing, or belt may be shortened.
* After you replaced the belt with a new one,
check the tension again after the initial stretch
of the belt is settled.
Keep the belt for the crankshaft
pulley or alternator free from oil and
grease.
* Otherwise, a slip may occur, which shortens the
service life of the belt.
