Operating Instructions .
The Chuck has been adjusted
too far down causing the adjust-
ment threads to be disengaged.
Re-adjust to a lower position
which may require you to use

while in the down position.
Push up on the Chuck and rotate
slowly while holding the Spindle

into a locked position.
The Needle Bearings on the Idler
Pulley(s) are not lubricated.
Lubricate the Needle Bearings as

The Chuck adjustment is designed for a 1/4” total move-
ment up and down. Once you have sharpened the drill bit
down more than a 1/4” from its original length you must
replace it. Any drill bits that are longer than approx 2-1/4”
or shorter than approx 2” may cause Chuck adjustment
problems.
