3/8" DRILL
When drilling metals, use light oil on the drill bit to keep
it from overheating. The oil will prolong the life of the drill
bit and improve the cutting action. If the bit jams in the
workpiece, or if the drill stalls, release the trigger switch
immediately. Remove the bit from the workpiece and
determine the reason for jamming.
REMOVING THE CHUCK
To remove the chuck:
1. Remove the drill plug from the power source.
2. Insert a 5/16"(8 mm) or larger hex key (1) into the chuck
(2) and tighten the chuck jaws securely (Fig. 7). Make
sure each of the chuck jaws (3) is seated on the flat
surfaces of the hex key.
3. Tap the hex key sharply with a mallet (4) in a clockwise
direction. This action will loosen the screw in the chuck
for easy removal.
4. Open chuck jaws and remove the hex key.
5. Open the chuck jaws as far as possible.
6. Remove the chuck screw using a #2 screwdriver
(Fig. 8)
NOTE: Turn the screw CLOCKWISE to remove it.
This screw has a left-handed thread. Insert the hex
key into the chuck and tighten jaws of chuck securely
(Fig. 9). Tap the hex key sharply with a mallet in a
COUNTERCLOCKWISE direction. This will loosen the
chuck on the spindle. The chuck can now be unscrewed
and removed from the spindle by hand.
Insert the hex key into the chuck and tighten jaws of
chuck securely (Fig. 9). Tap the hex key sharply with a
mallet in a COUNTERCLOCKWISE direction. This will
loosen the chuck on the spindle. The chuck can now be
unscrewed and removed from the spindle by hand.
RETIGHTENING A LOOSE CHUCK
After installing a chuck that has previously been removed,
the chuck may become loose on the spindle and develop
a wobble. Also, the chuck screw may become loose,
causing the chuck jaws to bind and prevent them from
closing. To tighten the chuck, follow these steps:
1. Insert the hex key into the chuck and tighten the chuck
securely.
2. Tap the hex key sharply with a mallet in a CLOCKWISE
direction (Fig. 10). This will tighten the chuck on the
spindle.
3. Open the chuck jaws and remove the hex key.
4. Tighten the chuck screw using a #2 screwdriver.
NOTE: Turn the screw COUNTERCLOCKWISE to tighten
it. This screw has a left-handed thread.
