7. NOTE ANY UNUSUAL NOISE
Operators familiar with daily engine operation
soon become alert to any noise not normally present.
This is very valuable in correcting defects in
the early stages and preventing expensive repairs
or delays.
I. REPEAT DALLY OPERATIONS OUTLINED
Follow previous instructions.
CHECK FAN BELT TENSION
Inspect wear con-
"~~ dition of fan belt;
note alignment and
check belt tension
which should allow
not over ~" deflection
on long span on
narrow belts. (On
wide belts the deflection
should be
between ~/_r"-l". )
2. CHANGE CRANKCASE OIL
Engine life is dependent upon clean oil being
circulated to all moving parts; therefore, the frequency
of oil changes and oil filter replacement is
very important and should be made at regular,
scheduled periods.
The schedui!e for changing oil is directly dependent
upon the operational environment: an extremely
clean operation could go 150 hours while
a dirty operx!ion (foundry or cement factory)
could be 50 hours or less.
Replace the oil filter element every 150 hours
unless extremely unfavorable operating conditions
indicate that filter replacements should be made
at every oil change period.
Thoroughly clean the filter, cover and sealing
surfaces, before replacing new element and gasket.

5. CHECK BATTERY
Check specific gravity of each cell -- which
should be at least 1.250. Add distilled water, if required,
to raise level ~/8" above the separators.
Particular attention should be given battery
during cold weather. The cranking power of a fully
charged battery @ 80 ° F. is reduced 60% @ 0 ° F.
-- yet the power required to crank the engine is
2~/2 times greater @ 0 ° F. than @ 80 ° F.
3. SERVICE AIR CLEANER
If oil-bath air cleaner is used, remove bottom
half of air cleaner-- clean thoroughly and fill with
engine oil to oil level mark on cup, avoid overfilling.
Replace cup and check all connections to manifold.
Be sure that no unfiltered air can enter the
engine intake ~.anifold.
If a dry type air cleaner is used, clean element
with compressed air.

6. LUBRICATE GENERATOR AND STARTER
Apply 3-5 drops of engine oil to each cup on the
generator and if required on the starter (Many
starters have sealed bearings).
