Strimmer Maintenance

Before You Start: Important Points

Grass trimmers use a rotating mowing line to quickly cut long grass and get it under control; brushcutters function similarly and may use blades for tougher undergrowth. Always read the operating instructions to understand key maintenance tasks.

Only perform maintenance as advised in your operating instructions. For all other repairs, visit Gustharts.

Choosing the Right Fuel for Your Petrol Grass Trimmer

Use the right fuel for your petrol trimmer or brushcutter: we recommend STIHL MotoMix. Ready-mixed, low emissions, high performance, and long-term storage. The STIHL filling system prevents fuel spillage.

Checking the Cutting Tool

Regularly check your mowing heads or blades as part of your maintenance routine:

1. Line mowing heads: Ensure line is wound correctly, no crossover. Replace with genuine STIHL line if necessary.
2. PolyCut blades: Inspect for cracks and replace all three blades together.
3. Metal cutting tools: Sharpen if needed, replace if bent or broken.

Why Won't My Brushcutter or Grass Trimmer Start?
