How to Start a Gas Weed Eater

By Lisa Larsen ; Updated September 21, 2017
A perfect-looking lawn requires a weed eater.

Gas weed eaters, also known as string trimmers or weed whackers, are an invaluable tool when it comes to lawn maintenance. Their long shaft allows you to reach small places and areas that are difficult to navigate with a lawn mower. They are lightweight, making them easy to operate no matter your size or strength. The convenience of running on gas allows you to take them anywhere. Starting a gas weed eater is easy if you follow some simple steps.

Weed eaters make lawn care easy.

Check the weed eater’s gas reservoir and, if necessary, add gas. It is best to use a high-quality gas with a high octane level.

Always wear eye protection.

Put on eye protection. Slide the on-off switch to the “on” position. This switch is located on the shaft, three or four inches below the engine.

Many lawn tools make lawn care easy.

Locate the primer bulb, which will be on the side of the engine. Depress the bulb three to five times, observing the fuel’s progression out of the tank and into the fuel line. When the fuel line is completely full, stop pumping the primer bulb.

Make sure the choke is on.

Locate the choke lever, which is usually just above the primer bulb. Slide the choke to the "on" position.

No need to hire a goat!

Depress the throttle trigger, which is located on the shaft near the on-off switch.

Weed eaters replace many tools.

Using a rapid motion, tug the starter cord, then allow it to rewind. Tug it again, still keeping the throttle depressed. If the engine is cold, tug the starter cord a third time.

Keep your lawn beautiful.

Slide the choke lever to the "off" position. With the throttle still depressed, again pull the starter cord.

Enjoy your beautfiul lawn.

Rev up the engine several times until it runs smoothly when the throttle is released.
