Reassemble the accessory and perform a short pressure test to verify there are no leaks.

Regularly inspect O-rings and safety plugs for signs of wear, cracking or deformation. Replace seals at the first sign of damage and keep a spare set to minimise downtime. Use manufacturer-recommended lubricants if needed and ensure parts are compatible with your Kärcher model.
