6 - Trouble Shooting Guide
6.1 - Determining the Cause and Correction to Certain Problems
Problem
Uncommon metallic sounds
from under the shroud.
The Chuck cannot be
adjusted according to the
Operating Instructions.
Cause
The Drive Pulley is loose.
The Needle Bearings on the Idler
Pulley(s) are not lubricated.
The Chuck has been adjusted
too far down causing the adjust-
ment threads to be disengaged.
The Chuck has been rotated
while in the down position.
Note:
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.
Correction
Adjust the Drive Pulley to the
proper height and tighten or
replace the Set Screw.
Lubricate the Needle Bearings as
needed.
Re-adjust to a lower position
which may require you to use
new hollow drill bits.
Push up on the Chuck and rotate
slowly while holding the Spindle
stationary until the Chuck returns
into a locked position.
