Install and Remove Bits
Your tool is equipped with a one hand collet,
making bit installation and removal easy and
fast.
Lock the variable-speed trigger switch "OFF"
by placing the direction-of-rotation selector in
the center position.
To install the bit:
Insert the bit directly as far as it will go into the
collet. Check to make sure that the bit is firmly
in place. (Fig. 9a)
To remove the bit:
Pull the locking sleeve forward (away from
the tool), pull the bit from the collet, and then
release the sleeve. (Fig. 9b)

that has power groove. Do not use bits that have a damaged shank.
WARNING

Wear protective gloves when removing the bit from the tool, or first
allow the bit to cool down. The bit may be hot after prolonged use.
