DRILLING – cont’d
NOTE: Make sure the hand placed on the body
of the drill does not cover the air vents. Covering
these air vents will reduce 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.
Squeeze the switch trigger to start the drill.
NOTES: 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 the 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 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.
HORIZONTAL DRILLING SPIRIT LEVEL
When drilling in a horizontal position, you can
use the horizontal spirit level (1) that is located
on the rear of the drill housing (Fig. 13). The drill
bit will be in the horizontal position then the spirit
level bubble (2) is centered between the lines
(3).
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.
