GENERAL LUBRICATION PROCEDURES
Recommended intervals are based on normal conditions of operation, temperature, and humidity. When
operating under extreme conditions, such as high or low temperatures, fording in water over 20 Inches deep, or exposure
to sand or dust, lubricants should always be changed more frequently. Lubricants that have become contaminated will be
changed regardless of interval. When in doubt, notify your supervisor.
