DRILLING
– cont’d
1. Check drill bit to make sure it is firmly
locked into the drill chuck and the
forward/reverse switch is in the forward
position.
2. Set torque clutch to highest setting.
3. Hold the drill firmly with both hands
whenever possible. Use one hand to
grasp the handle and switch and the
other to grasp the body of the drill.
NOTE:
Make sure the hand placed on
the body of the drill does not cover the
air vents. Covering these air vents will
reduce the motor cooling and possibly
lead to overheating the motor.
4. While holding the drill firmly, place the
point of the drill bit at the point to be
drilled. Depress the switch trigger to
start the drill.
NOTE:
Always use a higher drill speed
when drilling small holes. Use a slower
drill speed when drilling large holes.
5. Move the drill bit into the workpiece
applying only enough pressure to keep
the bit cutting. Do not force the drill bit
or apply sideways pressure to elongate
the hole.
WARNING:
Be prepared for
binding and bit breakthrough. When
these situations occur, the drill bit has a
tendency to grab the workpiece. This
action will kick the drill opposite to the
direction of drill bit rotation and could
cause loss of control when breaking
through material as you complete
drilling the hole. If you are not prepared,
this loss of control can result in serious
injury.
When drilling metals, use a light oil on the
drill bit to keep it from overheating. The oil
will prolong the life of the drill bit and
improve the drill 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.
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 flats of the bit
are gripped by the chuck jaws.
3. Set the torque clutch to the appropriate
setting based on the chart shown on
Page 13.
NOTE:
If material is particularly soft or
porous, set the torque clutch at 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 at a
higher setting.
NOTE:
Do not continue to drive the
screw once the clutch has released.
This will damage the clutch.
CHUCK REMOVAL
The drill chuck must be removed in order to
use some accessories. To remove the
chuck:
