Dusty Environments
Clean the following components:
•
Engine air filter: Clean the dust evacuator frequently.
•
Radiator: Clean the radiator core frequently to prevent blockage.
•
Fuel equipment: Clean the filter parts frequently.
•
Fresh air and recirculation filters: Clean the filters frequently.
Rocky Ground Surface
Tracks should be set slightly loose from what is required for other environments. While track tension is normally
0.75 - 1.75 in. (20 - 45 mm), SANY recommends that you loosen the track track tension to 1.75
in. (45 mm) for
rocky ground surfaces. Inspect the tracks for damage, such as cracks, or loose or missing bolts or nuts.
NOTE:
This applies to metal track only, SANY does not recommend using rubber track on rocky ground
surface.
Cold Environments
In extremely cold environments (below 32° F (0° C)), lubricate only with the oils shown in “Engine Oil Viscosity/
Temperature Data” on page 5-9. SANY recommends the use of fuels identified in “Fluids and Lubricants” on
page 5-8 for extremely cold environments. Prior to starting the engine, ensure that the battery is fully charged and
that 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 past experience and suggestions by lubricating oil suppliers, the lubricating intervals listed in the
following tables apply only to normal operating conditions. In harsh environments, including dusty and corrosive
air, abnormal external temperature, extremely heavy overload, frequent operating times, long time duty cycle, etc.,
lubricating intervals should be shortened.
