Stihl BG 50 Pull Start Rope Replacement

はじめに

Use this guide to replace a broken or worn-down pull start rope from a Stihl BG 50 gas-powered leaf blower.

The purpose of the pull start rope is to start the combustion engine. The rope can become brittle if it is not used frequently or it may begin to tear after extensive use. If the rope is only dirty it is not necessary to replace it. If the rope has already broken, Step 2 can be skipped.

Be sure to removing the fuel from the blower’s fuel tank to prevent a fire hazard.

The old rope should be disposed of, but the pull start handle can be kept as a spare part.
