Case 2050M Operator's Manual page 166

Hour meter
The hour meter enables service operations to be sched-
uled. Its hourly indications are the same as those of a
clock when the engine is running.
Servicing intervals are carefully calculated to guarantee
safe and efficient machine operation.
Be sure to carry out all the servicing operations properly
as defined in this manual.
Variable periodic maintenance
Some working environments require that maintenance be performed more frequently. Dust, dirt, moisture, extreme hot
or cold, and many other factors should be taken into consideration when servicing the machine. Certain equipment or
auxiliary tools may cause more stress on hydraulics, drivetrain, engines, or filters. The following maintenance should
be performed on regular schedules, but often need special attention when conditions require.
Engine air filter
Replace the primary element if the air filter indicator lamp
illuminates.
Inspect the filter for damage. Wipe off the filter seal, and
clean all dust from air cleaner housing. Never use water
to clean the primary filter. For complete information see
the maintenance chart on page 7-25 and air filter replace-
ment on page7-83.
Track
Clean the tracks and undercarriage as required or at the
end of the work shift. Park the machine on a level sur-
face to prevent distortion of the track seals. If the tem-
perature is cold, park the machine on a surface that will
not freeze to the track shoes. Check the track tension fre-
quently when you operate. Check the track tension more
often when working in extreme conditions. When material
packs and collects on the undercarriage, the tracks may
become too tight. Correct track adjustment is the most
important factor that helps to control undercarriage wear.
7 - MAINTENANCE
Radiator
Check the machine for debris, especially around the en-
gine area and radiator. Make sure these areas are clean.
Check the level of the coolant tank.
Fuel prefilter
Check for water in the fuel system. Cold temperatures
can cause water to collect in the fuel tank. Check the first
stage fuel filter for water. Drain any sediment and/or water
that collects in the fuel system. This should be a periodic
maintenance procedure dependent upon climate and use
conditions.
Fuses
If a fuse is defective, an indicator light will illuminate. Al-
ways replace fuses with a fuse of the correct amperage.
NOTE: If a fuse blows, replace it at once. Locate the
problem and if it reoccurs, have it checked by a service
technician.
