How to Tension the Chain on a Chainsaw

In the video below, a Weingartz expert demonstrates how to tension the chain on a chainsaw. Please refer to your owner’s manual for detailed safety procedures.

  • Locate the nuts that hold the bar to the saw
  • Loosen the nuts
  • Locate the adjusting screw for the chain rate in center of the two nuts
  • Tighten the screw to adjust the chain
  • Use slight pressure while adjusting chain so that the drive links slightly come out of the bar and groove itself
  • Hold the bar up and tighten the nuts
  • Make sure the chain spins freely
  • Check the braking mechanism
