Out-of-Service Protection
Protect an engine to be out-of-service for
more than 30 days as folio tvs:
1. Run unit until thoroughly warm.
2. Turn off fuel supply.
3. Drain oil from oil base while still warm.
Refill and attach a warning tag stating oil
viscosity used.
4. Service air cleaner and cover with plastic.
5. Wipe entire unit. Coat rustable parts with a
light film of grease or oil.
6. Cover air inlet and outlet openings.
7. Disconnect battery and follow standard
storage procedures.
Service and Maintenance
Regularly scheduled maintenance is the key
to lower operating costs and longer service life
for the unit. However, actual operating condi¬
tions under which a unit is run should be the
determining factor in establishing a main¬
tenance schedule. When operating in very
dusty or dirty conditions, some of the service
periods
may
have
to
be
reduced.
The
schedules are divided into two categories:
Owner Maintenance Schedule — performed by
the owner, and Critical Maintenance Schedule
— performed by qualified service personnel.
For any abnormalities in operation, unusual
noises from engine
or generator, loss of
power, overheating, etc., contact your dealer
or factory.
Crankcase Oil
Check the oil level every 4 hours of operating
or before each time the unit is used. Change
oil every 25 hours but more often if operated
in extremely dusty or dirty conditions. For
the first fill of oil on a new unit, change oil
after two hours operation.
The oil capacity of the engine is 21 ounces.
Fill to the oil level which is 1/8 inch below
the top of the oil fill opening (C). Pour slowly
to prevent trapping air.
When adding oil between changes, alwaysuse
the same brand that is in the crankcase.
Various brands of oil may not be compatible
when mixed. Ambient temperatures must be
the guide for selection of the proper weight
oil. Following are recommendations:
Above 32 F — use SAE 30
Below 32 F - use SAE 10W
For L.P.G. fuel operation, use an ashless or
low ash detergent oil specifically made for
gaseous-fueled (L.P.G.) engines. If not avail¬
able, use an oil with the A.P.I. designation SE
or SE/CC. Don't use an oil with the designa¬
tion CD unless it is also designated SE and the
oil manufacturer certifies it will perform
satisfactorily in gasoline engines.
Note: If oils with these designations are not
yet available, use an oil with the API designa¬
tion MS, MS/DG or MS/DM which has passed
all the Automotive Manufacturer's Sequence
Tests and the MIL-L-2104B Tests.
Air Cleaner
The polyurethane type air cleaner (B) must
normally be cleaned every 25 hours, more
often if the engine runs rich and emits black,
smoky exhaust due to clogged air cleaner
element. To service the air cleaner, remove
the air cleaner cover. Then remove the poly¬
urethane element and wash in a detergent and
water
solution
as you would a sponge.
Squeeze out the cleaning solution and re-oil
the element by applying generous amounts of
oil to the sides and open ends. Squeeze to
distribute the oil and remove excess oil.
Reinstall the element and air cleaner cover.
Crankcase Breather
To remove the crankcase breather assembly
(located behind cylinder intake pipe), take
out the fastening screws and lift off the
breather assembly. The breather has the filter¬
ing element held in the cover by a small barb.
Depress the element with a blade between the
element and
cover.
Once the element is
loosened from the barb, the element can be
removed from the cover.
Clean the element with a suitable solvent or
household detergent. Blow out the solvent or
cleanser used with low pressure air. When
re-installing the breather assembly, the drain
hole or rectangular opening is at the bottom.
Note: The filtering element doesn't have to be
lubricated before re-installing because it's
lubricated by crankcase vapors during opera¬
tion.
Ignition
Every 100 hours, remove, inspect, clean and
regap the spark plug to .020". If the plug
looks discolored or has fouled, replace it.
Because the plug used is a special length plug
for installation, use the same plug type as the
original or equivalent.
