4.5 Periodic inspection and cleaning (approx. 1,000 hrs)
For fuels with a low ash content, cleaning and inspection after approx. 1,000 service
hours is usually sufficient (under normal use conditions, approximately every quarter).
For less efficient fuels and fuels with a high ash content (indicated by short emptying
intervals for the ash container), the work should be carried out more frequently
accordingly.
