Section VI Maintenance
Periodically clean the drive rolls of dirt and chips. Occasionally check the wear of liners,
tips, and guides.
Periodically check, and replace if necessary, the carbon brushes on the motor. Failure to
replace worn brushes could cause severe damage to motor control.
Maintenance and electrical work must be performed by experienced and trained
personnel.
Whenever repairs are required, always turn all power controls off and disconnect all
electrical cables from power supply.
