ADJUSTMENTS
GENERAL REMARKS
® Before adjustment, wipe the tape contacting surfaces clean
as well as the contacting surfaces of the driving parts with a
soft cloth soaked in alcohol. |
Trouble may occur because of oil and grease stains.
® Carefully handle the belt because grease easily attaches to
it. Then, check the used rubber parts. lf the rubber has
deteriorated or is scratched, replace the parts with new ones.
