REFILLING THE STIHL AUTOCUT C 3-2 MOWING HEAD

Easily replace the trimmer line in your AutoCut C 3-2 by simply swapping out the spool with a pre-wound replacement. While more experienced users can opt to manually restring the line, replacing the entire spool is the most straightforward method.

IS YOUR NYLON LINE BRITTLE AND HARD TO WORK WITH?

When Nylon Line is stored it can become brittle and difficult to work with, we recommend soaking the new mowing line in water for at least 24 hours before loading it in your Grass Trimmer. Hydrating the nylon line increases its elasticity. You can keep the mowing line wrapped around the reel and place it directly into the water.

SUMMARY: HOW TO REFILL AUTOCUT 3-2 WITH NYLON?

• Replace spool with a new pre-wound spool. Simply pop out and swap.
• You can replace only the line, but this is more difficult and requires practise
• Use max 8m of 1.6mm or 5m of 2.0mm line.
• Soak new nylon line in water 24+ hours before loading to increase elasticity.
• You can soak the line while wrapped on the reel.
