GENERAL MAINTENANCE
A well-maintained machine is a productive machine. If not properly maintained, it could be unsafe or break down. Schedule regular maintenance
check-ups to ensure efcient performance and a long life. The following maintenance should be performed by a service center:
• Mechanical inspection and cleaning (pulleys, belts, bearings, nuts, bolts, housing, labels, etc.).
• Replacing worn or damaged parts (switches, guards, belts, etc.).
• Electrical inspection (switch, cord, plugs, etc.).
• Testing to assure proper mechanical and electrical operation.
• Replacing labeling.
Keep machine in good repair by adopting a regular maintenance program. Before use, examine the general condition. If abnormal noise or
vibration occurs, turn the grinder off immediately and have the problem corrected before further use.
Cleaning
• Clean dust and debris from wheels and housing.
• Keep the grinder handle clean, dry, and free of oil or grease.
• Use only mild soap and a damp cloth to clean machine, as some cleaning agents and solvents are harmful to plastics and other insulated
parts. Some of these include: gasoline, turpentine, lacquer thinner, paint thinner, chlorinated cleaning solvents, ammonia and household
detergents containing ammonia. Never use ammable or combustible solvents around machinery.
• Do not pressure-wash grinder. Getting motor or control box wet could cause electric shock or damage the grinders electrical components.
WARNING: BEFORE PERFORMING ANY MAINTENANCE WORK, DISCONNECT THE TOOL FROM THE POWER SOURCE.
WARNING: NEVER DISASSEMBLE THE MACHINE OR TRY TO DO ANY REWIRING ON THE MACHINE’S ELECTRICAL SYSTEM.
