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 fi rmly on spark plug. If
this happens reform the terminal to fi t fi rmly on spark
plug tip.
5. Carbon Canister: Designed to collect, store,
and dispose of fuel vapors created in the fuel tank /
fuel system. Remove and clean or replace the fi lter
on the canister when maintaining your air fi lter. The
canister will last the life of the unit.
GENERATOR CARE
Proper care and maintenance of the generator is nec-
essary 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 suffi cient to
warm the unit up and to dry out any moisture that has
accumulated in the windings. If left, this moisture can
cause corrosion in the winding. 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
service including the installation or replacement of
parts should be performed only by a qualifi ed electri-
cal service technician. USE ONLY FACTORY AP-
PROVED 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 dam-
aged or cracked receptacles can be both dan-
gerous 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 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 fi ns and fl ywheel. Clean more often
if necessary. Failure to keep these areas clean may
cause overheating and permanent damage to the
unit.
2. Periodically clean muffl er area to remove all
grass, dirt and combustible debris to prevent a fi re.
3. On engine muffl ers equipped with spark arrest-
ers, the spark arrester must be removed every 50
hours for cleaning and inspection. Replace if dam-
aged.
