Inspection, Maintenance and Adjustment
Maintenance Required
Perform a walk around inspection to check for any loose
fittings, obvious damage to the machine or any fluid leakage.
After completing operations, clean mud, rocks or debris from
the machine. Inspect for damage, cracked welds or loosened
parts.
Perform all daily lubrication and service.
If the operations were in salt water or other corrosive materials,
make sure to flush the affected equipment with fresh water.
Clean the air intake filters on a more frequent basis.
Clean the radiator and oil cooler fins to remove embedded dirt
and dust.
Clean the fuel system intake strainer and fuel filter more
frequently.
Inspect and clean as required the starter and alternator.
Check the undercarriage and track assemblies for damage or
excessive wear.
Inspect for loose or damaged fittings or bolts.
Relax track tension.
On a more frequent basis, inspect the front end attachments for
damage or excessive wear.
Install a top guard and front guard as required for protection
against falling rock.
Use the proper fuel for the temperature conditions.
Using a hydrometer, check the antifreeze to make sure that it is
providing the proper cold weather freeze protection.
Verify the condition of the batteries. In extremely cold weather
remove the batteries at night and store them in a warmer area.
Remove mud buildup as soon as possible to prevent it from
freezing to the undercarriage and causing damage.
