6.1.2 Cleaning the motor fan sieve
The motor fan sieve must be cleaned with a compressed air piston
once a month. In the case of very fluffy material to be sewn, the
motor fan sieve must be cleaned more frequently.

Cleaning steps:
1. Switch off the power supply at the main switch.
2. Remove any sewing dust and thread remains using a com-
pressed-air pistol or a brush.
Risk of injury due to flying particles.
Switch off the machine at the main power switch
before cleaning the motor fan sieve.
Flying dirt particles can get in the eyes, causing
injury.
Hold the compressed-air pistol in such a way that
no particles fly near persons.
Take care that no particles fly into the oil pan.
