Maintenance

Dusty Environments

Clean the following components:
• Engine air filter: Clean the dust evacuator frequently. Immediately service the air filter and housing if an
air filter restriction indicator is displayed. See "Check and Replace the Engine Air Filters" on page 5-36.
• Radiator: Clean the radiator core frequently to prevent blockage.
• Fuel equipment: Drain sediment frequently.
• Fresh-air and recirculation filters: Clean the filters frequently.

Cold Environments

In cold environments (32°F [0°C] or below), lubricate only with the oils and fuel shown in "Recommended
Lubricants, Fuels, and Engine Coolant" on page 5-10. Prior to starting the engine, make sure the battery is fully
charged and the battery case and the cables have not cracked.

Other Weather Environments

NOTE: If there is evidence of overheating of bearings or bushings, loose parts, or rust during regular
inspection, increase the frequency of lubrication.
Based on experience and suggestions by lubricating oil suppliers, the lubricating intervals listed in the
"Maintenance Schedule" on page 5-14 apply only to normal operating conditions. In harsh environments, including
those with dusty and corrosive air, abnormal external temperature, extremely heavy overload, frequent operating
times, longtime duty cycle, etc., lubricating intervals should be shortened. Always follow the "Maintenance
Schedule" on page 5-14 until enough experience is obtained to establish a new schedule.

Check the Maintenance Log

The maintenance log lists regularly scheduled maintenance that should be performed by the operator or service
personnel. All maintenance performed on the machine must be recorded in the maintenance log.
