OPERATING INSTRUCTIONS

the

Assembly Diagram on page 14.

WARNING! Remove the Battery (4) from the tool and set the Rotation

2. To install a drill/screwdriver bit, hold the Chuck Sleeve firmly in place and turn the

Chuck (12)

. Insert the shank of the bit all the way into the Chuck

(12). While holding the Chuck Sleeve in place, turn the Chuck

clockwise

to lock the

bit in place. The Chuck (12) accepts up to

” diameter bits. Insert the appropriate

bit for your application and tighten the Chuck (12) firmly. (See Figure E, above.)

3. Secure the workpiece in place, using a vise or clamps (not included).

4. The Torque Setting Ring (8) allows you to select 16 different driving torque settings,

depending on the job required.

Torque Settings (1-8):

The different numbers on the Ring are an indication of how much torque the

screwdriver will apply to the bit before the clutch slips, allowing the bit to stop

and helping to prevent damage to the screw, bit, or workpiece. The higher the

number, the more torque is applied before the clutch slips. Unless you are

drilling, always start with a lower number to help prevent damage. This drill also

has torque settings between the numbers to allow a greater range of control.
