You would not want to be your chainsaw broken or cause problems during any woodwork. Not only can it compromise your project or task, but also your safety. Troubleshooting your saw might be easier than you think. So, how do you fix Husqvarna chainsaw 455 rancher problems? 

Let’s break down the common problems with this chainsaw and how to fix them. 

Common Husqvarna Chainsaw 455 Rancher Issues + Best Solutions

Issue #1: Defective Engine Due to Bad Airflow

Your engine requires good airflow to burn fuel. Improper combustion will wreck the engine’s efficiency. 

Solution: Replace the Air Filter

Check the air filter if there’s a blockage. If so, replace it. Take out the dirty filter, then place a new filter. You can find affordable ones, and filters are easy to install. 

Issue #2: Bad Fuel System or Bad Fuel Mix

A poor fuel mix causes your chainsaw to run lean or rich. Both scenarios can wear out your engine.

Solution #1: Check Fuel Tank Level

Ensure that your engine’s tank has enough fuel. 

Solution #2: Check the Correct Fuel Mix

Ensure your engine is running on a good fuel mix. If you haven’t used your saw for a long time, dispose of the old fuel and replace it with a new fuel mix. 

Solution #3: Refill With Fresh and High-Quality Fuel

Make sure you’re using high-quality, premium fuel. It will help keep the efficiency of your chainsaw.

Solution #4: Inspect the Fuel Lines

The fuel line connects to the fuel tank. Check the fuel lines for cracks or damages. If you find any physical damage, replace it. 

Solution #5: Unclog or Replace Carburetor

Check if the carburetor is clogged. Clean the buildup, or better yet, replace the carburetor entirely for a better running engine.

Issue #3: Ignition Failure Due to Bad Spark Plugs

Spark plugs are critical components in the spark system. A faulty ignition occurs due to bad spark plugs, and that’s harmful to the saw’s engine. 

Solution #1: Inspect the Spark Plugs Closer

Check the spark plugs if they are worn out. This might create a gap between electrodes. So, inspect for gaps or other dirt issues. If any issue persists, our engineers recommend replacing the spark plugs.

How to Check the Spark Plugs?

  1. Locate the spark plugs. 
  2. Remove it and check for dirt buildup. Clean it as needed. 
  3. Attach the spark plug wire. Touch the metal plug head and pull the cord. 
  4. If there are sparks, your system is fine. If not, check the gaps. Ensure the gaps are enough as too much gap causes electrode spark failure or a lesser gap halts air to incite an ignition.
  5. If the gap is too big, spark plugs might be worn out over time. So, we recommend replacing them entirely. 

Issue #4: Husqvarna 455 Rancher Won't Start or Hard to Start

If your Husqvarna chainsaw doesn’t start, you may try the following quick fixes:

Solution #1: Unclog or Replace Dirty Air Filter

Check the air filter for clogs. Clean the filter to let air flow through smoothly. Or, if it’s worn out, replace the dirty air filter.

Solution #2: Check Piston Ring for Damages (High Or Low Compression)

If you’re in low compression, check for leaking pieces and replace them. However, if you’re on high compression, a worn-out or damaged piston ring can cause low compression. Make sure to replace faulty piston rings. 

Solution #3: Replace Damaged and Faulty Spark Plug

Inspect for spark plug damage. If you find any physical damage, we advise replacing the spark plugs.

Solution #4: Work With the Stubborn Starter During Cold Weather Conditions

Cold weather can cause starting issues with your chainsaw. In this case, search for the choke to start the saw. Most chainsaws have a choke position for colder weather. 

This will boost the fuel flow of the chainsaw from the carburetor fuel and air mixture. 

Issue #5: Husqvarna 455 Rancher Loses Tension

When your chainsaw loses tension, it may cause high vibrations, and its chain may lose over time.
