Assembly

The Bosch model PS21 Cordless Drill/Driver has a chuck that accepts any 1/4" hex bit. The low RPM capability of this model is not a deficiency. On the contrary, low speed means high torque and high torque is a definite plus for efficient drilling and driving. The low speed also provides more control to prevent stripout of the screw and damage to the work surface.

INSERTING AND REMOVING ACCESSORIES To avoid loss of control, ensure bit is locked in chuck

by pulling on bit after it has been inserted.

Your tool is equipped with a quick release chuck. To insert an accessory, simply pull locking sleeve forward, insert desired accessory into chuck until the locking sleeve retracts automatically, locking the bit (Fig. 2).

To remove an accessory, pull locking sleeve forward and simply remove it from the chuck.
