Hose keeps disconnecting from the vacuum or tools during use.

Safety first: Remove the battery before inspecting hose connections.

• Inspect hose ends: Check the hose cuffs for cracks, wear, or missing locking tabs.
• Check inlet collar: Inspect the vacuum’s hose inlet for damage or deformation.
• Use correct hose: Ensure you are using a Hilti hose compatible with your vacuum model.
• Replace worn parts: Replace the hose or cuff if it no longer locks securely.
