WARNING!
• The inside of the tension adjusting device of
the rubber track is greased. Grease is under
high pressure associated with the tension of
the rubber track. Failure to follow
precautions stated below when removing
grease may lead to a serious accident due to
the grease valve being popping out.
• Only one full turn of the tension adjusting
grease valve is allowed to loosen. The
grease valve may pop out if disregarded.
• Always stand aside when conducting
tension adjustment of the grease valve to
circumvent potential dangers.
• Ensure that grease is completely removed
from the inside of the rubber track before
rotating the sprocket to remove the rubber
track.
