3. Operation
When operating engine on JP-8, F24, JET-A or JP-5 fuel, a load of up to 900W can be applied.
Engine has been de-rated to 750W for 4000 ft and 95°F operation; at sea level a load of up to
900W may be applied continuously without causing the engine to stall and a maximum load of
up to 1000W for brief surge capacity. No other modifications or special operating procedures
are required.
When performing procedures in this Section, it is important to follow steps in their given order.
3.1 Operation Time and Power Rating
•Limit operation requiring maximum power to brief surge capacity.
•Maximum power in parallel operation is: 2.0 kVA.
•Rated power in parallel operation is: 1.8 kVA
•For continuous operation, do not exceed the rated power.
•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.
•It is not recommended to operate at no load conditions for long periods of time
3.2 Pre-operation - Warnings, Cautions, and Checking the Engine
3.2.1 Pre-operation Safety, Warnings, and Cautions
Safety is your responsibility. Understand and abide by all safety warnings stated in this Operation
and Maintenance Manual. Read and understand this manual. Know what the controls do and
how to operate them. Familiarize yourself with the generator and its operation before using it.
Know how to shut off the generator in an emergency. If the generator is being used to power
appliances, be sure they do not exceed the generator’s load rating.
To prevent an injury or damage the equipment, check the condition of the generator before
operating. Be sure to take care of any problems or send the generator back to Novatio to fix any
problems, before operating the generator.
•Improperly maintaining this generator or failing to correct problems before
operation, could cause a malfunction in which could result in serious injuries.
Always perform a pre-operation inspection before each operation, and correct
any problem.
WARNINGS

Ex-Power DEFENDER –Operation and Maintenance Manual
Novatio Engineering Confidential Document
3-2
•Exhaust contains poisonous carbon monoxide gas that can build up to
dangerous levels in closed areas. Breathing carbon monoxide can cause
unconsciousness or death.
•Never run generator in a closed or even partly closed area where people may be
present.
•Use grounded 3-prong extension cords, tools, and appliances, or double-
insulated tools and appliances.
•Inspect cords and plugs, and replace if damaged.
•Make sure that the appliance is in good working order. Faulty appliances or
power cords can create a potential for electric shock.
•Operate generator at least 3 feet (1 meter) away from buildings and other
equipment.
•Do not operate generator in an enclosed structure.
•Keep all cooling holes open and clear of debris, mud, water, etc. Cooling holes
are located on the side panel, the control panel, and the bottom of the
generator. If the cooling holes are blocked, the generator may overheat and
damage the engine, inverter, or windings.
•Do not lay the generator on its side when moving, storing, or operating it. Oil
may leak and damage the engine or property.
•Make sure 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 between rated and maximum may be used for only brief surge
capacity.
3.2.2 Check the Engine before Starting
Check the oil level (see Section 5.2). A low oil level will cause the Oil Level Indicator system to
shut down the engine.
Check the air filter (see Section 5.4). A contaminated air filter will restrict air flow to the
carburetor, reducing engine and generator performance.
Check the fuel level (shown below) by opening cap vent lever (ON position to release internal
pressure), removing fuel tank cap, and checking fuel level. If adding fuel, ensure that JP-8 and
F24 fuels are not mixed. Starting with a full tank, will help to eliminate or reduce operating
interruptions for refueling.
