Bosch Power Tools PS20 manual Operating Instructions

The Bosch model PS20 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

!WARNING 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.

One inch bits should only be used along with a bit holder as shown in figure 2.

TRIGGER CONTROLLED VARIABLE SPEED Your tool is equipped with a variable speed trigger switch. The tool speed can be controlled from minimum to maximum nameplate rated RPM by the pressure you apply to the trigger. Apply more pressure to increase the speed and release pressure to decrease speed (Fig. 1).

BRAKE

When the trigger switch is released it activates the brake to stop the chuck quickly. This is especially useful in the repetitive driving and removal of screws.

FORWARD/REVERSING LEVER

& TRIGGER LOCK

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 chuck, and for locking the trigger in an “OFF” position to help prevent accidental starts and accidental battery discharge. 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.
