FIRE SAFETY NOTICE
Keep multi-class ABC fire extinguishers handy. Class A fires involve ordinary combustible materials such
as wood and cloth. Class B fires involve combustible and flammable liquid fuels and gaseous fuels. Class C
fires involve live electrical equipment.
WARNING
The "WARNING" symbol above is a sign that a procedure has a safety risk involved and may cause death or
serious personal injury if not performed safely and within the parameters set forth in this manual.
●Failure to follow instructions provided in this manual may result in death, serious
personal injury and/or severe product and property damage, including voiding all
or portions of the warranty.

●Do not operate equipment when mentally or physically fatigued or after
consuming alcohol or drugs.
●Do not use starting fluids which can cause an explosion and may result in death,
serious personal injury and/or severe product and property damage. Do not use
evaporative starting fluids. They are highly explosive.
●Installing or maintaining a generator can cause severe personal injury. Wear
personal protective equipment including safety glasses, hard hats, steel-toed
shoes and protective clothing when working on equipment.
●Benzene, found in some fuels, and used engine oils have been identified by some
state and federal authorities to cause cancer or reproductive toxicity. Do not
ingest, breathe fumes or come into contact with gas or oil when checking,
draining or adding gas and oil.
●Hot, moving and electrically-live parts can result in death, serious personal injury
and/or severe product and property damage. Only trained and experienced
personnel should make adjustments while the generator is running. Otherwise,
adjustments should be made only when the generator is not running.
●Moving parts can catch on loose clothing items or jewelry. Do not wear loose
clothing or jewelry near moving parts including shafts, fans, belts and pulleys.
●Moving parts can seriously injure body appendages, including fingers. Keep
hands away from moving parts. Keep protective guards in place over fans, belts,
pulleys and other moving parts.
●Improperly installed electrical connections may result in death, serious personal
injury and/ or severe product and property damage. Electrical connections must
be made by trained and experienced electricians in accordance with applicable
codes.
●Back-feeding to shore power may result in death, serious personal injury and/or
severe product and property damage. The generator must not be connected to
shorepower or any other source of electrical power. An approved switching
3

device must be used to prevent interconnections and serious damage to the
generator.
●Operating, servicing and maintaining and maintaining this equipment can expose
you to chemicals, including engine exhaust, carbon monoxide, phthalates and
lead, which are known to the State of California to cause cancer and birth defects
or other reproductive harm. To minimize exposure, avoid breathing exhaust, do
not idle the engine except as necessary, service your equipment in a
well-ventilated area and wear gloves or wash your hands.
●Do not install generator on a watercraft or boat. Such an installation might violate
U.S. Coast Guard regulations and may lead to damage, fire, injury, or death.
CAUTION
The "CAUTION" symbol above is a sign that a procedure has a safety risk involved and may cause personal
injury, product or property damage if not performed safely and within parameters set forth in this manual.
●Always wear eye protection when performing service, maintenance or installation
procedures. Other safety equipment to consider would be hearing protection,
gloves and possibly a full face shield, depending on the nature of the task.

3.1 HANGING FRAME DIMENSIONS

4.0 LIFTING AND HANDLING GENERATOR
When lifting a generator without a mounting frame, the generator should only be lifted from the
bottom. The generator should never be lifted by the housing. A solid surface, a pair of forks, or a pair of
straps can be placed underneath the generator to properly lift from the bottom. Care should be taken to
ensure that the generator is held horizontally during handling and is not tipped which could spill oil. Care
should also be taken to ensure that no fork or strap contacts the exhaust outlet on the bottom of the
generator, as this contact during lifting/moving could bend or break connections in the muffler and
exhaust system. Further care should be taken during handling to ensure that fuel/LP lines are not
pinched or crushed.
When lifting a generator with a mounting frame, the generator can be lifted either by A) the upper
frame where the mounting holes are located or (B) from the bottom.

5.0 LOCATION, MOUNTING, AND VENTILATION
This generator is designed to be installed into or onto a vehicle and must be securely mounted to the
vehicle. It has to be installed in an area safe from road debris and must be guarded in such a way that
the vehicle cannot be damaged by heat or vapors. The generator has to have exhaust, fuel, and
electrical all installed correctly to safely function. A proper location must include all of the following:
●Enough space based on the generator dimensions shown above.
●Enough space to connect and disconnect fuel lines, a remote control wiring harness, and AC
power output lines.
●Enough space to access the front control panel for starting/stopping the generator and
performing all periodic maintenance.
●Separation from any flammable vapors or liquids, including fuel tanks and batteries, to prevent
the generator from igniting these substances.
●Access to the bottom of the generator for draining oil, changing the oil filter, and installing
exhaust.
●Ground clearance of at least 12 inches.
