Cleaning Cooling Fins

CAUTION: Avoid injury! Compressed air can cause debris to fly a long distance.

  • Clear work area of bystanders.
  • Wear eye protection when using compressed air for cleaning purposes.
  • Reduce compressed air pressure to 210 kPa (2.1 bar) (30 psi).

IMPORTANT: Avoid damage! Reduced air intake can cause overheating. Keep radiator cooling fins clean.

Do not use pressure washers to clean radiator and cooling fins. The force produced by pressure washers can damage the radiator and cooling fins.

Reduce compressed air pressure to 210 kPa (2.1 bar) (30 psi) when cleaning radiator and cooling fins. Spray compressed air straight into radiator. Do not spray radiator on an angle or cooling fins can be bent.

  1. Park machine safely. (See Parking Safely in the Safety section.)

  2. Allow engine to cool.

  3. Raise hood.
