Most Common Chainsaw Problems and How to Solve Them

 

Chain Won’t Move

Possible Causes:

  1. Chain tension too loose. If the chain is too loose, it won’t move when the saw is in use. This can happen if the chain stretches or isn't tightened correctly.
  2. Chain tension too tight. If the chain is too tight, it may bind and not move at all.
  3. Bar oil system clogged.The bar oil system lubricates the chain and bar. If it's clogged, the chain might not move properly.

Step-by-step guide to fixing a chain that won’t move:

  1. Check chain tension:Lift the chain away from the bar. If it lifts more than 1/8 inch, it's too loose. If it doesn't lift at all, it's too tight.
  2. Adjust chain tension:Use the tensioning screw to adjust the chain. Turn it in the direction indicated in the manual until the tension is correct.
  3. Clean bar oil system:Remove the bar and chain, then clean the oil system with a cloth. Check the reservoir and make sure it's free of debris.

 

Engine Won’t Start

Possible Causes:

Dirty air filter. A dirty air filter can block airflow to the engine and prevent it from starting.

Fuel system clogged.A clogged fuel system can stop the engine from getting the fuel it needs to start.

Spark plug issue.A faulty spark plug can prevent the engine from igniting the fuel, making it impossible to start.

Step-by-step guide to fixing an engine that won’t start:

  1. Check air filter:Remove the air filter and inspect it for dirt. Clean or replace it if necessary.
  2. Clean fuel system: Drain the fuel and replace it with fresh fuel. Clean the fuel lines and filter with a cloth.
  3. Replace spark plug:Remove the old spark plug and install a new one. Ensure the gap is set correctly before tightening.

 

Chain Slipping Off

Possible Causes:

  1. Worn sprocket nose.Over time, the sprocket nose can wear down, causing the chain to slip off.
  2. Dull or damaged chain. A dull or broken chain is more likely to slip off during cutting.
  3. Loose bar nuts.If the bar nuts are loose, the bar may shift, causing the chain to slip off.

Step-by-step guide to fixing a chain slipping off:

  1. Check sprocket nose:Remove the chain and inspect the sprocket nose for wear. Replace it if needed.
  2. Sharpen or replace chain:Use a file to sharpen the chain, or replace it if it's damaged beyond repair.
  3. Tighten bar nuts:Use a wrench to tighten the bar nuts evenly. This prevents the bar from shifting and keeps the chain secure.

 

Chain Overheating

Possible Causes:

  1. Dull or damaged chain.A dull or damaged chain can cause excessive friction, leading to overheating.
  2. Chain tension too tight.If the chain is too tight, it can create extra friction and cause overheating.
  3. Insufficient chain lubrication.Without proper lubrication, the chain can overheat due to friction.

Step-by-step guide to fixing a chain overheating:

  1. Sharpen or replace the chain:If the chain is worn out, sharpen it or replace it with a new one.
  2. Adjust chain tension:Loosen the bar nuts and adjust the chain tension according to the manufacturer’s instructions.
  3. Lubricate the chain:Apply bar and chain oil to the moving parts of the chain. Distribute the oil evenly to avoid over-lubrication.

 

Engine Overheating:

Possible Causes:

  1. Dirty air filter.A dirty air filter restricts airflow, which can lead to engine overheating.
  2. Fuel system clogged. A clogged fuel system can prevent the engine from running efficiently, leading to overheating.
  3. Spark plug issue. A dirty or worn spark plug can cause the engine to run inefficiently and overheat.

Step-by-step guide to fixing an engine overheating:

  1. Clean air filter: Remove the air filter and wash it with soap and water. Dry it completely before reinstalling.
  2. Clean fuel system: Drain the fuel tank and carburetor, then clean the fuel lines and filter. Refill with fresh fuel afterward.
  3. Replace spark plug:Remove the old spark plug and install a new one that matches the manufacturer’s specifications.
