There are two techniques to changing this switch. Technique 1 is faster but carries slight risk of 
damaging the front silver case (while bending the case down as shown in step 5) and is only 
recommended for technicians who are comfortable running the risk of causing damage. 
Technique 2 requires more disassembly and is longer, but is less likely to cause damage to the 
silver case. Please read both techniques to see which one is best for your skill level. 

 

Technique 1 (faster but more difficult) 

*** Unplug the grinder from power supply *** 

 

1.  Remove the case 
2.  -WARNING- Although the capacitor will be discharged unless there are 

extenuating circumstances, exercise caution as it potentially has a high voltage 
charge that can shock you if the contacts are touched.
