Use And Care Manual

DRILLING – cont’d
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/driver stalls, release the trigger switch
immediately. Remove the bit from the workpiece
and determine the reason for jamming.
DRIVING SCREWS
When driving screws, care must be taken to use
the bit that correctly fits the screw being driven.
Make sure you use the largest bit size that will
properly fit into the head of the screw.
1. Select the correct screwdriver bit for the
screw being driven.
2. Fasten the screwdriver bit into the chuck,
making sure the flat sides of the bit are
gripped by the chuck jaws.
3. Set the torque clutch to the appropriate
setting, based on the chart on Page 12.
NOTE:
If the workpiece material is particularly
soft or porous, set the torque clutch to a lower
setting to avoid overdriving the screw.
4. If the screw is driven too far into the
workpiece before the clutch releases, set
the clutch to a lower setting, and do not pull
the trigger switch fully back. If the screw is
not driven far enough into the workpiece,
set the clutch to a higher setting.
NOTE: Do not continue to drive the screw once
the clutch has released. This causes
unnecessary wear of the clutch.
RETIGHTENING A LOOSE CHUCK
1. Remove the battery pack from the
drill/driver.
2. Insert a 5/16” (8 mm) or larger hex key (1)
into the chuck (2) and tighten the chuck
jaws securely (Fig. 12). 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 the chuck jaws and remove the hex
key.
5. Tighten the chuck screw using a
#2 screwdriver (Fig 13).
NOTE: Turn the screw COUNTER-
CLOCKWISE to tighten it. This screw has a left-
handed thread.
