SY155U Excavator OMM
Dusty Environments
Clean the following components:
• Engine air filter: Clean the dust valve frequently.
• 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 extremely cold environments, 32°F (0°C) or below,
lubricate only with the oils as shown in “Engine Oil
Viscosity/Temperature Data” on page 5-9. SANY
recommends the use of fuels identified in “Fuel” on
page 5-8 for extremely cold environments. Prior to
starting the engine, make sure the battery is fully charged
and the cables have not cracked.
Contact a SANY dealer for assistance if the machine will
be operated in freezing temperatures where the aid of an
auxiliary heating device is needed.
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 5-12 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 5-12 until enough
experience is obtained to establish a new schedule.
Check the Maintenance Log
Check the maintenance log if all tasks have been
completed before 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.
