3. PREVENTIVE MAINTENANCE
3.1 SAFETY INSPECTION GUIDE
The purpose of this inspection guide is to aid you in identifying unsafe conditions.
If any unsafe conditions exist, then find out how serious the hazard could be and if you can
continue before you correct the hazard.
Check the following items:
 Damaged, missing, or altered parts, especially in the area of the On/Off switch and the power
supply
 Damaged, missing, or altered covers, especially in the area of the top cover and the power
supply cover
3.2 LUBRICATION SPECIFICATIONS
FRUs are typically lubricated as needed from the factory. If not, then lubricate only when parts are
replaced or as needed, not on a scheduled basis. Use of lubricants other than those specified can
cause premature failure. Some unauthorized lubricants may chemically attack parts. Lubricate
gears that were lubricated in the original part.
