Change the oil
after the first month or 20 hours of op-
eration and every 6 months or 100 hours thereafter un-
der normal operating conditions. Change engine oil
every 25 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. Fill
to the “
FULL
” mark on the dipstick.

Dual Element Air Filter:
Clean and or replace foam
pre-cleaner and air filter every 6 months or 100 hours.
Service more often under dusty conditions.
a. Loosen screws and remove cover and air cleaner
assembly from base.
b. Remove foam pre-cleaner by sliding it off the
paper cartridge.
c. Wash foam pre-cleaner in liquid detergent and
Water.
d. Wrap foam pre-cleaner in cloth and squeeze dry.
e. Saturate foam pre-cleaner in engine oil. Squeeze
to remove excess oil.
f.
Clean Air filter using compressed air.
g. Install foam pre-cleaner over air filter.
h. Re-install the Air Filter assembly. Reassemble
cover and screw down tight.
Do not use petroleum solvents, such as kerosene, to
attempt to clean the cartridge. They may cause
deterioration of the cartridge. DO NOT OIL
CARTRIDGE. DO NOT USE PRESSURIZED AIR TO
CLEAN OR DRY CARTRIDGE.
4.
Spark Plug:
Clean and reset gap at .030” every 6
months or 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 terminal does not fi t firmly on spark plug. If this
happens reform the terminal to fi t firmly on spark plug
tip.
5.
Carbon Canister:
Designed to collect, store, and dis-
pose of fuel vapors created in the fuel tank / fuel sys-
tem. Remove and clean or replace the filter on the
canister when maintaining your air filter. The canister
will last the life of the unit.
GENERATOR CARE
Proper care and maintenance of the generator is neces-
sary to ensure a long trouble free life.
1.
Exercising The Generator -
The generator should
be operated every three to four weeks. It should be
operated for a period of time sufficient to warm the
unit up and to dry out any moisture that has accumu-
lated in the windings. If left, this moisture can cause
corrosion in the winding. Frequent operation of the
generator/engine set will also insure that the set is
operating properly should it be needed in an emer-
gency.
2.
Generator Maintenance -
Any major generator ser-
vice including the installation or replacement of parts
should be performed only by a qualified electrical
service
technician.
USE
ONLY
FACTORY
APPROVED REPAIR PARTS.
a. Bearing - The bearing used in these generators is a
heavy duty double sealed ball bearing. They require
no maintenance or lubrication.
b. Receptacles - Quality receptacles have been utilized.
If a receptacle should become cracked or otherwise
damaged, replace it. Using damaged or cracked re-
ceptacles can be both dangerous to the operator and
destructive 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 contami-
nate the fuel system and the generator components.
1. Keep the air inlet screen on both the engine and gen-
erator free of any dirt or debris to insure proper cool-
ing. At least yearly remove the blower housing on the
engine and clean the chaff and dirt out of the engine
cooling fins and fly wheel. Clean more often if neces-
sary. 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.
