MAINTENANCE SCHEDULE
Read through the manual before carrying out any
maintenance operations. Proper care of the roller is essential
to ensure satisfactory operation.
Keep the machine clean so that any leakage, loose bolts or
loose connections can be easily detected. Make a habit of
checking around the roller and also on the ground. This is
usually the easiest way to detect any leakage at an early
stage.
