BASE CLAMP
If additional clamping force is desired: use a
2.5 mm Allen wrench and turn the set screw
clockwise SLIGHTLY (1/8 turn or less), then
test clamp. Do not over-tighten.
COLLET CHUCK CARE
With the router bit removed, continue to turn
the collet chuck counter-clockwise until it is
free of the shaft. To assure a firm grip,
occasionally blow out the collet chuck with
compressed air, and clean the taper in the
armature assembly shaft with a tissue or fine
brush. The collet chuck is made up of two
component parts as illustrated (Fig. 30); check
to see that the collet is properly seated in the
collet chuck nut and lightly thread the collet
chuck back onto the armature shaft. Replace
worn or damaged collet chucks immediately.
