MAINTENANCE
Maintenance
Perform the scheduled maintenance procedures as defi ned
by Table 8 and below:
Engine Oil
Every 100 hours: Change engine oil after the fi rst 50 hours
of operation and 100 hours thereafter. Always check the
crankcase oil level prior to each use, or when the fuel tank
is fi lled. Insuffi cient oil may cause severe engine damage.
Make sure generator is level when checking oil level. The
oil level must be between the two notches on the dipstick
as shown in Figure 8.
1. Remove engine oil drain plug located at the bottom of
the generator enclosure (Figure 29) and drain oil from
crankcase.For best results drain oil while engine is
warm. Reinstall oil drain plug, and add engine oil as
specifi ed in Table 5. Crankcase oil capacity is 2.64 qts.
(2.5 liters).
Figure 29. Engine Oil Drain Plug
Oil Filter Cartridge
Every 200 hours: Replace the engine oil fi lter cartridge
after every 200 hours of operation.
1. Clean oil fi lter mounting base, and coat oil fi lter seal
(Figure 30) with clean engine oil.
Figure 30. Oil Filter Cartridge
2. Screw on new oil fi lter by hand until seal contacts the
fi lter mounting base. Install drain bolt with sealing
washer and hand tighten.
3. Replace engine oil with recommended type oil as listed
in Table 5. For engine oil capacity, see Table 2 (engine
specifi cations). Fill to upper limit as shown in Figure 8.
Engine Air Cleaner
Every 50 hours: The air cleaner employed on the
KUBOTA Z482 series engines is a dry type, NEVER
apply oil to it. If generator is used in severe dusty areas
service air cleaner element more frequently.
1. Release the air cleaner retaining clamps (Figure 31)
and remove the air cleaner element.
Figure 31. Air Cleaner
2. Wipe the inside of the air cleaner with a clamp cloth and
remove all dust and debris that may have accumulated
inside air cleaner body.
3. Tap the edge of element lightly to allow heavy dust
build-up to fall off.
4. Tap the paper fi lter element (Figure 31) several times on
a hard surface to remove dirt, or blow compressed air
[not exceeding 99 psi (686 kPa, 2.1 kgf/cm2)] through
the fi lter element from from the inside while turning
the element. NEVER brush off dirt. Brushing will force
dirt into the fi bers.
5. Replace the fi lter element once a year or every six
cleanings or if it is excessively dirty
NOTICE
When installing the oil fi lter, coat rubber seal with a
small amount of lubricant (motor oil). DO NOT over-
tighten cartridge. Hand tighten only.
