Maintenance Procedures
Oil and Oil Filter
When possible, drain the oil while it is warm.
1.
Before working on the generator set or connected
equipment, disable the generator set as follows:
a.
Press the OFF button on the generator set controller.
b.
Disconnect the power to the battery charger.
c.
Remove the battery cables, negative (--) lead first.
2.
For most models [except 8/10/12RESV(L)],
a
drain plug is located on the service side of the
generator set, opposite the starter. If you have
difficulty locating the drain plug, see the service
view in your generator set operation manual. For
8/10/12RESV(L)
, proceed to step 3.
a. Remove one oil drain plug and the oil fill cap/
dipstick. Aim the drain tube into catch basin
and open the valve near the oil sump. Allow
ample time for complete drainage.
b. Close the valve and place the tube back in the
clip on the bulkhead wall.
c. Remove the old filter and wipe off the
adapter/base on the engine.
d. Proceed to step 4.
3.
For 8/10/12RESV(L) models,
use the following
procedure to avoid spilling oil into the alternator.
a. To prevent oil from spilling into the alternator,
cover the alternator with rags around the areas
near the oil drain valve and oil filter.
b. Place a drain tube (3/8 in. inside diameter) onto
the oil drain valve and place the end of the tube
into a drain pan. The tube will reduce the
potential for spilled oil.
c. Open the oil drain valve on the engine.
d. Remove the dipstick and oil fill cap. Allow time
for the engine oil to drain completely.
e. Close the oil drain valve and remove the oil
drain tube.
f. Tilt the filter upward to prevent spilling as you
remove the oil filter. Remove the old filter and
wipe off the adapter/base on the engine.
4. Place a new replacement filter in a shallow pan with
the open end up. Pour new oil (provided) through
the threaded center hole. Stop pouring when the oil
reaches the bottom of threads. Allow a minute or
two for the oil to be absorbed by the filter material.
5. Apply a thin film of clean oil to the rubber gasket on
the new oil filter.
6. Install new oil filter. Hand tighten filter clockwise
until the rubber gasket contacts the adapter, then
tighten the filter an additional 3/4--1 turn.
7. Fill the crankcase with the new oil to the
F
or
FULL
mark on the dipstick. Use a funnel to prevent
spilling. Always check the level with the dipstick
before adding more oil. Never operate the engine
with the oil level below the
L
or
ADD
mark, or above
the
F
or
FULL
mark. See Figure 2.
8.
For 8/10/12RESV(L) models,
remove the rags
that were used to cover the alternator.
