FAQs: RedMax Hedge Trimmer HT230 Won’t Start

Why won’t my RedMax hedge trimmer start?

There are a few possible reasons why your RedMax hedge trimmer won’t start. Here are some of the most common:

The engine is flooded: If the engine is flooded, it means that too much fuel has been added to the carburetor. This can prevent the engine from starting because the spark plug will not be able to ignite the fuel. To fix this problem, you will need to drain the excess fuel from the carburetor.

The spark plug is fouled: A fouled spark plug can also prevent the engine from starting. This is because the spark plug will not be able to create a spark strong enough to ignite the fuel. To fix this problem, you will need to clean or replace the spark plug.

The air filter is dirty: A dirty air filter can restrict the flow of air to the carburetor, which can cause the engine to run lean and not start. To fix this problem, you will need to clean or replace the air filter.

The fuel filter is clogged: A clogged fuel filter can prevent the engine from getting enough fuel to start. To fix this problem, you will need to clean or replace the fuel filter.

The carburetor is out of adjustment: The carburetor is responsible for mixing the fuel and air in the correct proportions. If the carburetor is out of adjustment, it can cause the engine to run lean or rich, which can prevent it from starting. To fix this problem, you will need to adjust the carburetor.
