OPERATOR CARE AND MAINTENANCE
ENGINE CARE
-
If major engine service or repair is re-
quired contact an Authorized Engine Service Center.
-
The manufacturer of these engines has established an
excellent world-wide engine service organization. En-
gine service is very likely available from a nearby author-
ized dealer or distributor. Check the yellow pages of
your local telephone directory under
"Engines-
Gasoline" for the closest engine repair center or ask
the dealer from whom you purchased the power plant.
1.
Oil Changes
Change the oil after the first 20 hours of operation
and every 100 hours thereafter under normal oper-
ating conditions. Change engine oil every 50 hours
of operation if the engine is operated under heavy
load, or in high ambient temperatures.
A. Remove oil drain plug at base of the engine and
drain the oil with the engine warm.
B. Replace oil drain plug.
C .Remove oil filler plug and refill with new oil. Refer
to the table in the engine manual for the proper
grade of oil based on your operating temperature.
D.
Replace filler plug.
2.Checking the Oil Level. The oil level must always be
checked before the engine is started. Take care to
remove any dirt or debris from around the oil fill plug
before removing. Be sure the oil level is maintained.
FILLTO POINT OF OVERFLOWING or on units with
the extended oil fill to the "FULL" mark on the
dipstick.
-
If the engine generator should fail to start and run,
check to be sure that the low oil protection system
has not been activated by a low oil condition.
3.
Servicing Air Cleaners
A
.Cleaning Air Cleaner Element
-
clean and re-oil
foam air cleaner at three month intervals or every
50 hours, which ever occurs first. Service more
often under dusty conditions.
1. Remove air cleaner cover and take the element
out.
2.
Wash element in kerosene or liquid detergent
and water.
3. Wrap foam pre-cleaner in cloth and squeeze
dry-
4.
Saturate in engine oil. Squeeze to remove ex-
cess oil.
5. Install element in the air cleaner body. Be sure
to install with the surface marked "inside" fac-
ing toward the carburetor.
4.
Spark Plug
-
Clean and reset gap at .030" every 100
hours of operation. Do not blast clean spark plug.
Clean by scraping or wire brushing and washing with
a commercial solvent. Poor spark will occur if ter-
minal does not fit firmly on spark plug. If this hap-
pens re-form the terminal to fit firmly on spark plug
tip.
GENERATOR CARE
-
Proper care and maintenance of
the generator is necessary to insure a long trouble free
life.
1.
Exercising The Generator
-
The generator should be
operated every three to four weeks. It should be op-
erated for a period of time sufficient to warm the unit
up and to dry out any moisture that has accumulated
in the winds. If left this moisture can cause corro-
sion in the winding and on the slip rings. Frequent
operation of the engine generator set will also insure
that the set is operating properly should it be needed
in an emergency.
2. Generator Maintenance
-
Any major generator ser-
vice including the installation or replacement of
parts should be performed only by a qualified elec-
trical service man. USE ONLY FACTORY APPROVED
REPAIR PARTS.
A.
Bearing
-
The bearing when used in these gener-
ators is heavy duty double sealed ball bearing. It
requires no maintenance or lubrication.
B. Brushes
-
Under ordinary circumstances brushes
will operate for long periods without requiring re-
placement. They should be inspected after
1000
hours of operation and every 100 hours thereafter.
When operating in dusty conditions check more
often to insure the slip ring and brush contact
area is clean and not wearing excessively.
C. Receptacles
-
Quality receptacles have been util-
ized. If a receptacle should become cracked or
otherwise damaged, replace it. Using damaged or
cracked receptacles can be dangerous both to the
operator and to the equipment.
CLEANING
-
Remove dirt and debris with a cloth or
brush. DO NOT use high pressure spray to clean either
the engine or the generator. This high pressure spray
could contaminate the fuel system and the generator
components.
1. Keep the air inlet screen on both the engine and
generator free of any dirt or debris to insure proper
cooling. At least yearly remove the blower housing
on the engine and clean the chaff and dirt out of the
engine cooling fins and flywheel. Clean more often
if necessary, failure to keep these areas clean may
cause overheating and permanent damage to the
unit.
2.
Periodically clean muffler area to remove all grass,
dirt and combustible debris to prevent a fire.
3.
On engine mufflers equipped with spark arresters, the
spark arrester must be removed every 50 hours for
cleaning and inspection. Replace if damaged.
