Stihl 026 Chainsaw: Common Problems and Solutions

The Stihl 026 is a reliable chainsaw, valued for its performance and durability. However, certain issues may arise over time due to wear and tear or improper maintenance. Below are common problems encountered with the Stihl 026 and practical solutions to address them:


1. Starting Issues

Many Stihl 026 owners report challenges with starting, especially after prolonged storage or regular use.

Causes:

  • A clogged or improperly adjusted carburetor.
  • Dirty or damaged spark plug.
  • Old or contaminated fuel in the tank.

Solutions:

  • Clean the carburetor: Disassemble and use a carburetor cleaner to remove debris; adjust settings as per the user manual.
  • Inspect the spark plug: Check for carbon buildup or corrosion. Replace with a new spark plug if cleaning does not restore functionality.
  • Replace old fuel: Always use fresh fuel with the proper fuel-to-oil ratio (usually 50:1). Empty the tank and refill if the chainsaw has been idle.

2. Poor Idle or Stalling

The chainsaw may idle poorly or stall during operation, particularly under load.

Causes:

  • Air leaks in the fuel system or intake manifold.
  • A dirty fuel filter restricting flow.
  • Incorrect carburetor adjustment.

Solutions:

  • Seal air leaks: Check for cracks or loose connections in the fuel lines, intake manifold, or carburetor gaskets. Replace any defective parts.
  • Replace the fuel filter: Inspect the fuel filter at the end of the intake line and clean or replace it if clogged.
  • Adjust the carburetor: Use the adjustment screws (H, L, and Idle) to fine-tune engine performance.

3. Over Revving or High RPMS

The chainsaw revs excessively or becomes difficult to control at high speeds.

Causes:

  • Air leaks in the crankshaft seals or carburetor.
  • A worn throttle linkage or sticking throttle trigger.

Solutions:

  • Check for air leaks: Inspect crankshaft seals and carburetor gaskets for wear or damage. Replace as necessary.
  • Lubricate or replace the throttle linkage: Ensure smooth operation of the throttle trigger and repair or replace the linkage if faulty.

4. Oil Leaks

A frequent observation is oil leaking from the saw, leading to unnecessary mess and waste.

Causes:

  • Defective oil pump or oil seal.
  • Blockages in the oiler system.
  • Improper storage position (laying the saw flat).

Solutions:

  • Inspect the oil pump: Check for damage or blockages in the oil pump assembly. Clean or replace seals as needed.
  • Unclog the oiler system: Clear debris or sawdust from the chain oil ports and clean the bar groove.
  • Correct storage position: Always store the chainsaw upright to prevent oil seepage.

5. Chainsaw Won’t Turn Off

Some users report that the saw continues running even when the kill switch is engaged.

Causes:

  • Faulty or disconnected wiring in the kill switch system.
  • Stuck ignition module.

Solutions:

  • Check kill switch wiring: Inspect connections for damage or disconnection and repair accordingly.
  • Inspect the ignition module: If the ignition remains active, replace the ignition module.

6. Chain Not Moving or Cutting Properly

The chain may not rotate smoothly, or the saw might struggle to cut effectively.

Causes:

  • A dull or improperly tensioned chain.
  • Worn-out sprocket or clutch mechanism.

Solutions:

  • Sharpen or replace the chain: Use a chain sharpening kit or replace it if heavily worn.
  • Check chain tension: Ensure the chain is not too loose or too tight. Adjust the tension according to user manual guidelines.
  • Inspect the sprocket and clutch: Replace worn sprockets or clean the clutch mechanism to ensure proper operation.

Preventive Maintenance Tips for Stihl 026

  1. Clean the air filter regularly to ensure proper airflow to the engine.
  2. Replace the fuel filter and spark plug during routine seasonal maintenance.
  3. Store the chainsaw correctly by emptying fuel and oil tanks to prevent system clogging during long periods of inactivity.
  4. Check the bar and chain oiling system to ensure optimal lubrication.
