4. Attach the tip tool to the grinder
Rotate the collet nut by hand while pressing the
lock button to further depress the lock button.
In this state, the shaft is locked and the collet nut
can be loosened or tightened. (Fig. 8)
To attach the tip tool, insert the tip tool as far as it
will go and tighten the collet nut securely.
To detach the tip tool, the collet nut can usually be
rotated by hand, though occasionally it may be
tight.
If the collet nut is tight, use the provided collet
spanner to loosen it.
Iron powder on the collet nut, collet or shaft
screw may cause the collet nut to be diffi cult
to rotate. (Fig. 9)
Be sure to remove any powder before
attaching or detaching the tip tool.
NOTE
Very occasionally, the tip tool may be diffi cult
to detach from the collet.
If this happens, with the collet nut loosened,
press the end of the tool lightly against a hard
object. (Fig. 10)
