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.
3. Remove the adjustment assembly, unplug the red and black motor leads,
remove the (4) screws indicated below, and lift out to remove the gearbox/motor
assembly
5. Gently but firmly bent the silver down and away from the black. Use a wedge to
keep a gap between the silver and black portions of the case
6. Pry up the microswitch off the two posts it rests on by using a pick
Burr being used
as a wedge
7. Unplug the leads
8. Plug leads on to new switch
9. Install new switch on posts, taking care to orient the spring steel arm properly
(reference photo above)
10. Remove wedge
11. Replace 2 small screws (do not overtighten)
12. Install gearbox/motor assembly
13. Install case
Mounting posts
Spade connection
electrical leads

Technique 2 (longer but easier)
*** 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.
3. Remove the adjustment assembly, unplug the red and black motor leads, remove
the (4) screws indicated below, and lift out to remove the gearbox/motor assembly
4. Unplug the two cables from the display (indicated with yellow arrows)
5. Remove the (2) short screws behind the screen (indicated with red arrows)
6. Remove the (4) screws of the capacitor/PCB bracket (indicated with red)
7. Unplug the 2 pin and 3 pin Molex connectors from the PCB (not indicated – see
step 19 for picture of these connectors)
8. You can lift out the felt rings (indicated with white arrows), or leave them in place.
9. Lift up and remove the capacitor/PCB mount bracket
-continued below-
10. Remove the (10) screws indicated below
11. Remove the front two feet and the screws beneath
12. Partially remove the convertible arm assembly by pulling it towards the rear of
the unit. The hook may need to be adjusted for clearance.
13. Remove the silver front casing. If the silver front casing does not easily remove,
double check that all 14 screws securing it have been removed (2 under front feet,
10 in the back, 2 small screws right behind display)
14. Pry the interlock switch straight up and off the mounting posts
15. Pull the spade clip connectors to remove from the old switch. Push to insert
connectors on to new switch. Install new switch on mounting posts, taking care to
match the orientation of the spring-steel arm with the photo below.
16. Put the silver front case back in position and check that no wires are pinched.
Install the (2) screws under the front feet, and insert the front feet. Continue to
follow these instructions before installing more screws.
17. Route the brown and black interlock switch wires and green display wire (*which
is only on the 270Wi) exactly as shown below.
18. Plug both of the Molex connectors into the PCB, it is much easier to do it before
installing the capacitor/PCB bracket
19. Place the capacitor/PCB bracket in position and inspect wires for routing issues
20. Install (10) screws in back of grinder (reference step 9, will need to slightly lift
capacitor/PCB bracket to access top 2 screws)
Route wires to the
outside of the studs
Route wires to the
outside of the studs
The capacitor/PCB bracket is removed in this
photo and is being held vertically
3 pin Molex
connector plugged in
2 pin Molex
connector plugged in
21. Install (4) capacitor/PCB bracket screws, (2) short screws behind display, plug in
(2) wires into PCB noting that the power board to display wire inserts into the top
port (reference step 7)
22. 270W and 270Wi have felt dampening rings between the gearbox/motor
assembly and the chassis. Position as shown in step 8, then install the
gearbox/motor assembly
23. Install case
