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.

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.
ADJUSTABLE CLUTCH
Your tool features 10 clutch settings. Output torque will increase as the clutch ring, is
rotated from 1 to 10. The Drill “
” position will lock up the clutch to permit drilling and driving heavyduty work (Fig. 4).
BUILT IN WORK LIGHT
Your tool is also equipped with a light that turns on automatically when the switch is activated, for better visibility when drilling/driving (Fig. 4).
