Why does the arm system on my Husqvarna Construction Equipment make irregular movements?
- VVictor WhiteSep 10, 2025
If the arm system of your Husqvarna Construction Equipment makes irregular movements, it could be because the product or hydraulic oil is too cold; allow the product to warm up. Another cause could be air in the pilot control valve; operate the product with no load until the air and oil separate. If these steps don't resolve the issue, the pilot control valve or its spool may be defective due to contamination, requiring assistance from an approved service agent.
