How To Set Up and Fuel Your Chainsaw


A chainsaw can be a powerful and versatile addition to your garden tool collection. Here at SGS we’ve designed three incredibly user friendly domestic chainsaws, perfect for keeping the garden in check.

We’ve put together this comprehensive video guide to help you get your new SGS chainsaw ready for lopping down unruly branches or cutting logs for an open fire. Every tool you need to get started is included in the handy SGS toolkit provided with every chainsaw we ship. This video shows you the simple assembly for first time use, fuelling and priming the saw and starting your chainsaw for the first time.

In this video we’ve use the SCS5800, but this guide will work with the SCS2600 and SCS6200. You can see our full range of chainsaws here.

What You'll Need

  • A pair of tough gloves
  • The tool kit provided
  • The fuel mixing jug provided
  • 2-stoke oil
  • Unleaded petrol

Staying Safe When Using a Chainsaw

Wear strong safety footwear, snug fitting clothes and eye and hearing protection. A pair work gloves will help combat the chainsaws vibration. You can purchase a safety kit for your chainsaw here.

Never use a chainsaw if you’re unwell, tired or under the influence or medication or alcohol.

Keep your chainsaw chain sharp and the teeth even all way round the chain. You can see our chain sharpening guide here.

Mop up any fuel spillages as you go. Never use fuel around an open flame or while smoking.

Never start cutting until you have a clear work area, secure footing, and a retreat path from falling trees.

Never start a chainsaw in high wind, bad weather or when visibility is low.

Only ever start a chainsaw in a well ventilated area. Exhaust fumes contain dangerous carbon monoxide, and can kill easily.

Regular Inspection

Always inspect the chain saw before each use for worn, Ioose, or damaged parts. Never operate a chainsaw that is damaged, improperly adjusted, or is not completely and securely assembled. Be sure that the saw chain stops moving when the throttle control trigger is released.

We provide a list of spare for all our chainsaws and garden products, which you can find here.
