Why Your Hedge Trimmer is Smoking? Fixing Guide

Why Your Hedge Trimmer is Smoking?

Have you ever noticed that your hedge trimmer is smoking? If so, then you may have an issue with it emitting oil or gas. This can be a sign of a faulty carburetor or it’s an indication that you need to have your carburetor repaired. The motor is overworked, the blade is overheated, oil leaking, and/or the engine is under-protected from debris.

When your hedge trimmer starts to smoke, problems are bound to arise. No matter what the reason is though you will have to figure out its cause before it becomes permanent damage and you’ll then know what you need to do or replace to keep your hedge trimmer running smoothly again.

Types of Hedge Trimmers

In terms of power, both electric and gas models are pretty much similar. The difference is due to the availability of their power sources. The electric hedge trimmers get their power from an AC outlet or an extension cord. You plug it in, press the starter button and you’re ready to go.

The gas powered hedge trimmers run on gasoline and the only thing you need to start it is a match. The gas model is also slightly more powerful. However, it’s slightly more dangerous to use, due to its gas-powered engine.

What caused the Hedge Trimmer to Smoke?

The cause of smoke coming from a hedge trimmer is a problem in the fuel line. The fuel line is the metal tube from the gas tank to the carburetor. If the gas line is porous, the gasoline seeps out and evaporates into the air. If this happens, the carburetor can’t transfer the fuel to the engine. The excess vapor clogs the carburetor and causes smoke to come out of the exhaust pipe.

One of the biggest clues to determining the problem is the color of smoke.

Black Smoke in Hedge Trimmer

Gasoline powered hedge trimmers are very convenient, but they do have their quirks. If you have an issue with black smoke coming from the exhaust port, it most likely is a spark plug issue. Depending on the make and model of the trimmer you have, there may be an easy fix or a more complicated one. If the oil, fuel, and spark plug are okay, then you may need to clean or replace the spark plug.

However, the spark plug may not be the only possible culprit. So, check the air filter as well. If the air filter is clogged with debris, then it is definitely time to replace it.

White Smoke in Hedge Trimmer

White smoke is the sign of an engine burning the oil. This can be due to two reasons.

  • If you use the machine for a long time without oiling it, this will cause the engine to burn the oil.
  • If you oil it too much, then also the engine will burn the provided oil.

So, each time you oil your trimmer, start it and let it run for a couple of minutes and then stop it. This will increase the oiling and will do the trick.

What are the Reasons for White Smoke in Cordless Hedge Trimmer?

A battery’s connection to a motor may cause white smoke. Damage, such as corrosion from water, might be the cause. But, it’s usually the fault of component failure resulting in excess power transfer into components and eroding plastic casings.

What are the Health Hazards of Hedge Trimmer Smoke?

We’re not certain exactly what health problems you’re worried about, but we’d guess that the biggest single problem is that inhaling smoke is harmful to your lungs. Smoke is bad. If you are frequently using the trimmer, you may also be exposing yourself to chemicals and other products released by the trimmer that aren’t good for you, such as carbon monoxide. However, the risk is likely to be small.
