Mud, Rain, or Snow Conditions
Before operating the machine, inspect each connector for looseness.
After operating the machine, clean the machine and inspect for missing or loose fasteners. Add oil and lubricating
grease as needed.
Near Ocean (Salt Air) Environments
Before operating the machine, inspect for any signs of corrosion. Apply grease where rust is found.
After operating the machine, thoroughly wash away the salt residue, apply grease where rust is found, and perform
maintenance carefully on the electrical components to prevent corrosion.
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 the Engine Primary Air Filter System” on page 5-34
•
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 shown in “Engine Oil Viscosity/
Temperature Data” on page 5-13. SANY recommends fuels identified in“Fuel” on page 5-11 for extremely cold
environments. 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 5-15 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 5-15 until enough experience is obtained to establish a new schedule.
Maintenance Log
Check the maintenance log if all tasks have been completed before and after servicing or operating the machine.
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.
