LUBRICATION INSTRUCTIONS
General
Keep all lubricants in closed containers and store in a clean, dry place, away from external heat.
Keep container covers clean and allow no dust, dirt, or other foreign material to mix with the
lubricants. Keep all lubrication equipment clean and ready for use.
Cleaning
Keep all external parts not requiring lubrication free of lubricants. Before lubricating the equipment,
wipe all lubrication points free of dirt and grease. Clean all lubrication points after servicing to
prevent accumulation of foreign matter. Lubrication Interval
Service the lubrication points at the proper intervals as specified in the lubrication chart. The
intervals specified are based on operation under normal conditions. Modification of the
recommended intervals may be required under unusual operating conditions.
