When pressure washing the engine or underbody of your NAS Defender 110, pay special attention not to wash cavities that are prone to rusting. Cavities that do not have an outlet should be washed and cleaned by hand, using none corrosive liquids to avoid trapping water in underbody areas.

Prepare ahead and keep pressurized water away from entering cavities under the body or damaging components under the hood. Simply use plastic bags to block water penetration over and around these areas. Do not aim the pressure nozzle directly on to sensors, wires, or electric connectors when washing the underbody. Securely position plastic pegs over the distributor cap, fuse box, air breather, all sensitive wires, and connectors under the hood as shown above. Keep the pressured water nozzle at a safe distance from these sensitive components. For exposed surfaces and safe areas apply nozzle directly to area as needed to wash away excess grease, dirt, etc. Check with your local municipality to determine if environmental restrictions apply.
