Introduction

Keep your chainsaw in tip-top shape during the winter off-season by following these steps.

Tools Required

  • chip brush
  • Scrench
  • shop towels

Materials Required

  • Air filter
  • Fuel stabilizer
  • funnel
  • gas can
  • Spark plug
  • Two-stroke engine oil

Chainsaws, like all tools with small gas engines, must be put away for the winter properly. Winterizing your chainsaw before it sits for two or three months will save you lots of time and money in repairs. And it only takes about 15 minutes to ensure it’s ready to go in the spring.

Project step-by-step (7)

Step 1

Stabilize the Gas and the Engine

  • Add a fuel stabilizer to your two-stroke gas mixture and fill the chainsaw’s gas tank.
  • Run the engine until the machine is warm to coat the entire engine with the stabilized mix.

Step 2

Drain the Gas

  • Dump the gas back into your tank
    • Note: because the gas is stabilized, you can use it next season.
  • Pump your primer bulb while emptying the gas to flush all the gas out.
