Committed to Your Safety: Protective Equipment
Stay safe, confident, and in control — follow STIHL’s essential safety and technique tips for working with your grass trimmer or brushcutter.
Why Safety Equipment Matters
Working with powerful tools is rewarding, but only when done safely. Always wear personal protective equipment (PPE) when using your chainsaw, trimmer, or brushcutter — including a helmet, safety glasses, gloves, cut protection trousers, and boots.
Your product’s instruction manual outlines specific PPE requirements. Before every use, check your tool is in perfect condition. Your local STIHL dealer can help set up your machine and recommend suitable protective clothing that fits comfortably.
Note: Personal protective equipment is essential but does not replace safe working practices.

Before trimming, make sure your harness fits correctly. A properly adjusted harness balances the tool’s weight evenly across your shoulders and back, reducing fatigue and improving control.
Incorrect harness adjustment can make the trimmer unstable and increase strain. Ask your dealer for help fitting it correctly the first time.
Basic Grass Trimming Technique
Even for first-time users, trimming grass with a STIHL trimmer is simple and effective. The basic motion is a smooth semicircular sweep from right to left while moving forward slowly. This method ensures that cuttings fall onto the mown area, keeping your workspace tidy.
How to Use a Grass Trimmer in Tall Grass
For tall grass or dense weeds, use a two-stage technique:
- First, sweep from left to right at a higher level to cut the tops.
- Then, sweep back right to left near the ground to finish the cut.
This method reduces strain on the motor and helps distribute clippings evenly.
Working on Large, Level Areas
When tackling large, flat areas, use the quadrant method:
- Divide the area into smaller sections.
- Work methodically from the outer edges toward the centre.
This approach improves consistency and ensures no patches are missed.
Using a Grass Trimmer on Hills and Slopes
Always trim across slopes, not down them. Work in horizontal strips from one side to the other. When you reach the end of a strip, move up and cut another strip above it.
This method is safer, reduces slipping hazards, and keeps cuttings contained in the mown area.
Dealing with Obstacles and Borders
A string trimmer is ideal for cutting close to trees, fences, and shrubs. To protect bark and surfaces, use the trimmer guard as a guide and keep the line slightly angled.
For trees planted close together, trim a border around each trunk before mowing. Use the same technique for neat lawn edges along fences and flower beds.
