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.

Operating Instructions

PROTECTION AGAINST DEEP

DISCHARGING

The lithium ion battery is protected against deep discharging by the “Electronic Cell Protection (ECP)”. When the battery is empty, the tool is switched off by means of a protective circuit.

VARIABLE SPEED CONTROLLED

TRIGGER SWITCH

Your tool is equipped with a variable speed trigger switch. The tool can be turned "ON" or "OFF" by squeezing or releasing the trigger. The speed can be adjusted from the minimum to maximum nameplate RPM by the pressure you apply to the trigger. Apply more pressure to increase the speed and release pressure to decrease speed (Fig. 1).

FORWARD/REVERSING

LEVER & TRIGGER LOCK

After tool use, lock trigger in “OFF” position to help prevent

accidental starts and accidental discharge.

Your tool is equipped with a forward/ reversing lever and trigger lock located above the trigger (Fig. 3). This lever was designed for changing rotation of the bit, and for locking the trigger in an “OFF” position.

For forward rotation, (with chuck pointed away from you) move the lever to the far left.

For reverse rotation move the lever to the far right. To activate trigger lock move lever to the center off position.

Do not change direction of ! CAUTION rotation until the tool

comes to a complete stop. Shifting during rotation of the chuck can cause damage to the tool.
