Cat. No. 2403-20, 2404-20
This tool is equipped with a spindle lock. The chuck
can be tightened with one hand, creating higher grip
strengths on the bit.
1. To open the chuck jaws, turn the sleeve in the
counterclockwise direction.
When using drill bits, allow the bit to strike the
bottom of the chuck. Center the bit in the chuck
jaws and lift it about 1/16” off of the bottom.
When using screwdriver bits, insert the bit far
enough for the chuck jaws to grip the hex of the
bit.
2. To close the chuck jaws, turn the sleeve in the
clockwise direction. The bit is secure when the
chuck makes a ratcheting sound and the sleeve
can not be rotated any further.
3. To remove the bit, turn the sleeve in the coun-
terclockwise direction.
NOTE: A ratcheting sound may be heard when the
chuck is opened or closed. This noise is part of the
locking feature, and does not indicate a problem
with the chuck’s operation.
