WARNINGS
Failure to properly follow maintenance instructions and
precautions can cause serious injuries or death. Always
follow the inspection and maintenance recommendations
and schedules in this owner’s manual.
Safety Precautions:
Make sure the engine is off before you begin any maintenance
or repairs. This will eliminate several potential hazards:
Carbon monoxide poisoning from engine exhaust.
Be sure there is adequate ventilation whenever you
operate the engine.
Burns from hot parts.
Let the engine and exhaust system cool before touch-
ing.
Injury from moving parts.
Do not run the engine unless instructed to do so.
In the State of California a spark arrestor is required by law.
Other states may have similar laws. Federal laws apply on all
federal lands. If you equip the muffler with a spark arrestor, it
must be maintained in effective working order. See page 11.
Rapid retraction of the recoil starter cord can pull the
starter cord back faster than you can let go. When starting
the engine, pull the cord slowly until resistance is felt then
pull rapidly to avoid kickback.
AC Applications
Before connecting an appliance or power cord to the generator:
1. Make sure that appliances are in good working order.
Faulty appliances or power cords can create a potential for
electrical shock. If an appliance begins to operate abnor-
mally, becomes sluggish or stops suddenly, turn it off imme-
diately.
2. Disconnect the appliance, and determine whether the prob-
lem is the appliance, or if the rated load capacity of the gen-
erator has been exceeded.
3. Make sure that the electrical rating of the tool or appliance
does not exceed that of the generator. Never exceed the
maximum power rating of the generator. Power levels be-
tween rated and maximum may be used for no more than
30 minutes.
Substantial overloading will open the circuit breaker. Ex-
ceeding the time limit for maximum power operation or
slightly overloading the generator may not switch the
circuit breaker or circuit protector OFF, but will shorten the
service life of the generator.
Limit operation requiring maximum power to 30 minutes. For
continuous operation (longer than 30 minutes), do not exceed
80% of the rated power balanced equally on the A&B sides of
the Alternator.
The total power requirements (VA) of all appliances connected
must be considered. Appliance and power tool manufacturers
usually list rating information near the model number or serial
number.
Changing the speed of the generator by adjusting the governor can cause damage to the gen-
erator, devices attached to the generator, and may result in bodily injury. Do not adjust or
tamper with the engine speed setting.
