Operating Instructions

INTENDED USE

This tool is intended for the fastening and loosening of bolts, nuts and various threaded fasteners. This tool is not intended for use as a drill.

The Bosch model PS41 Cordless Impact Driver has a collet that accepts only standard 1/4” hexagonal shank accessories with power groove. 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 and release locking sleeve (Fig. 2).

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

Do not use this tool as a drill. Tools equipped with shut-off clutches are not designed for drilling applications. The clutch can shut off automatically and without warning. Attempting to restart drilling after shut-off has been reached can cause the tool to twist out of your hand until the clutch again reaches shut-off. Do not attempt to insert quick-change type drill bits into this chuck.

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).

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

!WARNING 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.
