Observance of all environmental protection regulations is required. Use high-pressure equipment as follows:

Caution: EYE INJURY

To avoid injury from flying debris, wear a face shield or goggles.

Notice: To prevent damage to engine components, keep the water moving at all times while cleaning. Never direct water onto electrical components, plug connectors, seals or flexible hoses.

Information on suitable cleaning and protective products is available from any authorized dealer. Note the equipment manufacturer's operating instructions.

Use the following minimum working distance between the high-pressure nozzle and the surface being cleaned:

  • Approximately 28 in. (700 mm) for circular pattern jets
  • Approximately 12 in. (300 mm) for 25-degree flat jets and dirt cutters

Power clean the engine as follows:

  1. Allow engine to cool down to room temperature before spraying the engine.
    2. Notice: Avoid all of the electrical connections with direct water or steam spray or damage can result.
  2. Thoroughly clean the entire engine using a steam cleaner or high pressure washer with mild soap and warm water.

    3. Warning: EYE INJURY

    To avoid injury from flying debris when using compressed air, wear adequate eye protection (face shield or safety goggles) and do not exceed 276 kPa (40 psi) air pressure.

    Note: Do not use compressed air or pressurized water to clean or dry the engine if any part of the engine is disassembled.
  3. Once the engine is clean, blow the electrical connectors dry with compressed air to remove most of the standing water.
  4. Allow the engine to dry completely before making any kind of repair.
  5. When reassembling, ensure that there is no standing water in any electrical connectors before seating the plug.
