the switch when not in use or carrying at your side,
when installing or removing the battery pack, and when

QUICK-CHANGE COLLET
See Figures 4 - 5, page 12.
NOTE: The tool ships with a preinstalled collet that is
machined to precision tolerances to fit accessories with
1/8 in. diameter shanks. When installed, the quick change
collet allows the user to change accessories without tools
and without removing the collet from the shaft. The quick
change collet is not compatible with 1/16 in. shanks.
To remove/install the quick change collet:
 Remove the battery pack from the tool.
 Lift the pen away from the pen holder.
 Slide the spindle lock lever forward and rotate the shaft by
hand until the spindle lock engages the shaft, preventing
further rotation.
 With the spindle lock engaged, place the included 3/8 in.
wrench on the bottom threaded end of the quick-change
collet and turn counterclockwise to loosen. Continue
turning counterclockwise to remove the collet from the
tool.
 Remove the quick-change collet.
 To install, engage the spindle lock. Place the quick-
change collet on the shaft and begin threading on by
hand until there is resistance. Then use the included 3/8
in. wrench on the bottom threaded end of the collet and
rotate clockwise until tightly secured.
WARNING:
Always use the collet which matches the shank size of the
accessory you plan to use. Never force a large diameter
shank into a collet. The accessory should fit smoothly
into the collet, but you should be able to tighten the ac-
cessory firmly and securely with the quick-change collet.
