SAFETY PRECAUTIONS

WARNING

Do not attempt to use this equipment until you have thoroughly read all the operation and maintenance manuals supplied with your machine. They include important safety precautions; detailed engine starting, operating, and maintenance instructions; and parts lists.

ELECTRIC SHOCK can kill.

• Do not touch electrically live parts or electrodes with your skin or wet clothing.

Insulate yourself from the work and ground.

Always wear dry insulating gloves.

ENGINE EXHAUST can kill.

Use in open, well ventilated areas or vent exhaust to the out-

side.

• Do not stack anything on or near the engine.

MOVING PARTS can injure.

Do not operate this equipment with any of its doors open or guards off.

• Stop the engine before servicing it.

• Keep away from moving parts.

Only qualified personnel should install, use, or ser- vice this equipment.

LOCATION AND VENTILATION

Whenever you use the WELDANPOWER 125, be sure that clean cooling air can flow through the machine’s gasoline engine and the generator. Avoid dusty, dirty areas. Also, keep the machine away from heat sources. Do not place the back end of the generator anywhere near hot engine exhaust from another machine. And of course, make sure that engine exhaust is ventilated to an open, outside area.

The WELDANPOWER 125 may be used outdoors. Do not set the machine in puddles or otherwise submerge it in water. Such practices pose safety hazards and cause improper operation and corrosion of parts.

Always operate the WELDANPOWER 125 with the case roof on and all machine components completely assembled. This will protect you from the dangers of moving parts, hot metal surfaces, and live electrical devices.

STORING

1.Store the machine in a cool, dry place when it’s not in use. Protect it from dust and dirt. Keep it where it can’t be accidentally damaged from con- struction activities, moving vehicles, and other hazards.

2.If you will be storing the machine for over 30 days, you should drain the fuel to protect fuel system and carburetor parts from gum deposits. Empty all fuel from the tank and run the engine until it stops from lack of fuel.

3.You can store the machine for up to 24 months if you use Briggs & Stratton Gasoline Additive, Part No. 5041 (available from any Authorized Briggs & Stratton Service Center), in the fuel system. Mix the additive with the fuel in the tank and run the engine for a short time to circulate the additive through the carburetor.

4.While the engine is still warm, drain the oil and refill with fresh 10W30 oil.

5.Remove the spark plug and pour approximately 1/2 ounce (15 ml) of engine oil into the cylinder. Replace the spark plug and crank the engine slow- ly to distribute the oil.

6.Clean any dirt and debris from the cylinder and cylinder head fins and housing, rotating screen, and muffler areas.

7.Store in a clean, dry area.
