Frequently Asked Questions

Why is the Nilfisk trigger so hard to press?

Stiffness is almost always due to trapped residual pressure in the hose. Switch off the machine, point the gun safely, and press the trigger to vent the pressure before your next use.

How do I unlock the Nilfisk trigger gun safety?

The Nilfisk trigger gun safety is a rotating collar or sliding tab near the trigger. Rotate it away from the trigger or slide it to the open position. Refer to your model's manual for the specific mechanism.

Can I replace the Nilfisk trigger gun myself?

Yes — Nilfisk trigger guns are universal in their fitting thread and are user-replaceable. Compatible trigger guns are available from Nilfisk dealers and online retailers.
