If the running time does not reach 1000 hours after 12 months, the required maintenance procedure of this period must be carried out during this period.

 

 

Overhaul

The reliability of the Deutz engine might be affected because of abrasion and corrosion. In order to avoid any working abmormity of the engine, we recommend the following overhaul. The first overhaul should be proceeded after the engine has runned for 2000 hours or after two years (running time less than 2000 hours).

5.2 maintenance procedure


5.2.1 cleaning up dry air filter


When the maintenance indicator of the filter shows a red signal or the engine performance is affected because of the resistance of the filter, clean the filter or change the filter element.

1. Dismount the main filter element.

2. Lay the end surface downwards and flap the filter element carefully. Or the filter element on clean ground and roll it to shake the dust off. Do not beat it forcibly.

3. Blow from the inside and outside the surface of the filter element with compressed air (less than 500kPa).

4. Clean up the sealing packing. It should be changed if there is any damage.

5. Check the dust outlet in the dust -discharging valve.

6. Reinstall. If the filter is mounted horizontally, place the dust-discharging valve vertically downward when mounting the cover.

 

Notice: The main filter element of a filter can only be cleaned up for at most 5 times. It must be changed after a year, and should be immediately changed if there is a damage. Mark the number of times which the main filter element has been cleaned or changed for in the exclusive marking column of the safe filter element. The safe filter element must be changed under following circumstance:

 

1) Main filter element has been maintained for 5 times

2) It has been used for 2 years.

3) As soon as the main filter element is maintained, the maintenance indicator will show immediately.

4) After the operation with a defective main filter element.

5) Safety filter element is not allowed to be cleaned.
