Installing Drill Bits and Chisels 
NOTE: Only use accessories with SDS or SDS Plus shanks.
Be sure that the shank of the bit is clean. Dirt particles may cause the bit to line up improperly. Do not use bits larger than the maximum recommended capacity of the drill because gear damage or motor overloading may result. For best performance, be sure that the bit is properly sharpened and the shank is lightly greased before use.
1.Insert the bit or chisel into the nose of the tool.
2.Rotate bit slowly until it aligns with the locking mechanism.
3.Push bit into tool until it locks.
4.Check that the bit is locked properly; it should be possible to pull the bit back and forth slightly (about 1/4”).
5.To remove bits and chisels, pull bit holder release collar toward the rear of tool and remove bit.
NOTE: Use caution when handling hot bits and chisels.
