SAFETY WARNINGS

♦

Place protective covers and guards over the rotating parts, if rotating parts such as the drive shaft, pulley,
belt, etc. are left exposed, they are potentially hazardous.

♦ When cleaning, repairing or inspecting, make sure all moving parts have stopped.

♦ Prior to working on the generator set, disconnect the spark plug and battery to prevent accidental starting.

♦ Use only original equipment or authorized replacement parts. Use of correct parts will assure the operator of

the safety integrity that was designed into the unit.

♦ Unauthorized modifications to the generator set may impair the function and/or safety of the unit.

♦ Do not operate the generator set without a muffler. Inspect periodically and replace if necessary.

♦ Do not touch the hot exhaust components or the high voltage spark plug and coil terminals. While Spark Plug

Voltages are not normally lethal, an involuntary jerk of the hand caused by a hot surface or by an electrical
shock can result in injury.

♦ Repair of electrical generating equipment requires specialized skills. Repair personnel must have a

thorough understanding of generator and small engine repair procedures.

♦ Never inhale exhaust gases. They contain carbon monoxide; a colorless, odorless and extremely

dangerous gas that can cause unconsciousness or death. Symptoms of carbon monoxide poisoning
can include: dizziness, nausea, headaches, sleepiness, vomiting or incoherency. If you or anyone else
experiences any of these symptoms, get out into the fresh air immediately. Shut the unit down and
do not operate it until it has been inspected and, if necessary, repaired.

♦ Never Operate the generator set indoors or in a poorly ventilated area such as a tunnel or cave.

♦ CALIFORNIA PROPOSITION 65 WARNING: engine exhaust from this product contains chemicals known to

the state of California to cause cancer, birth defects or other reproductive harm.

♦ Know how to stop the engine quickly and understand the operation of all controls.

- ii -

SAFETY WARNINGS

♦ Never permit anyone to operate the generator set without proper instructions.

♦ Never allow children to operate the generator set.

♦ Children and pets must be kept away from the area of operation due to the possibility of burns from hot

engine components or injury from any equipment the generator set is powering.

♦ Always wear eye protection and Hearing protection when working near the generator set.

♦ Operate the generator set only with the guards, shields and other safety items in place and working

properly.

♦ Do not put hands, feet, tools or other objects near rotating parts.

♦ Use reasonable care when moving or lifting the unit. The generator set may move around inside the wrap

frame creating "Pinch Points".

♦ Do not run the generator set while it is being moved.

♦ Do not support the generator set from the top of the wrap frame.

♦ Do not operate the generator set while under the influence of alcohol, drugs or medication.

♦ When transporting or using a generator set with the wheel option, secure the unit to prevent it from moving

around.

♦ Do not tamper with or change the engine speed as it has been preset at the factory for proper operation.

♦ Keep hands and face away from the carburetor when the air cleaner is being moved. A sudden backfire can

cause serious burns.

♦ Be careful of hot parts. The muffler and other generator parts become very hot while the engine is running.

♦ Do not "jump start" the generator set.

♦ Sulfuric acid can cause severe injury and can give off gases, which are corrosive and potentially explosive.

Avoid contact with skin, eyes, and clothing. In case of contact, flush area immediately with water.

♦ When transporting a generator set, secure it to prevent it from moving or shifting.

♦ Know how to stop the engine quickly and understand the operation of all controls.

♦ Do not operate electrical equipment while standing in water, on wet ground or with wet hands or shoes.

♦ Use extreme caution when working on electrical components. Potentially dangerous voltage is present

when the engine is running.

- iii -

SAFETY WARNINGS

○ ○ ○ ○ FOR GASOLINE OR DIESEL POWERED GENERATOR SETS ○ ○ ○ ○

♦ Operate the generator set on a level surface. If the generator set is tilted, fuel spillage may result.

♦ Handle fuel with care. It is highly flammable. Use only clean, properly marked and approved safety

containers for refueling and storing fuel.

♦ Stop the engine and allow it to cool before refueling.

♦ Do not overfill the fuel tank. Only fill the tank to within 1/2" of the top of the tank to allow space for fuel

expansion.

♦ If fuel is spilled, wipe it up carefully and wait until the fuel has dried before starting the engine.

♦ Make sure the fuel cap is properly closed after refueling.

♦ Never operate the generator set while smoking.

♦ Never operate the generator set near an open flame.
