REMOVING FIELD

1) Remove Motor housing cover set. Fan 100 secured with Hex nut M8 will be now visible.

2) Remove the assembly of Rear cover and Handle (switch side), then Brush holder caps and Carbon brushes.

Important:

When unscrewing Brush holder caps, be careful not to break the screwdriver insertion slot because the adhesive-applied

Brush holder caps are secured tight.

3) Remove hex nut M8 by turning counterclockwise with Socket bit 13-55 (No.784408-3) and Impact driver.

Now Fan 100 can be separated from Armature shaft. (Fig. 3)

Gear extractor, large (No.1R045). (Fig. 4)
