Turn the engine OFF before cleaning.
Preparation:
1. Switch off the engine
2. Remove the engine covers (replace them after cleaning)
3. Cover the electrical / electronic components and connectors (e.g. alternator,
starter, governor and solenoid)
4. Clean with compressed air to dislodge loose particles
Cleaning with a cold-cleaning solution:
1. Spray the engine with a commercial cold-cleaning solution and allow it to react
for approximately 10 minutes.
2. Spray the engine clean with a strong water jet, repeat if necessary.
3. Allow the engine to run warm so the remaining water can evaporate.
Cleaning with a high-pressure devise:
1. Clean the engine with a jet stream (max spray pressure of 60 bar or 870 psi), max
temperature of 90°C or 194°F).
2. Allow the engine to run warm so that remaining water evaporates.
