for the screw to grip! If restarting a screw in
a hole, locate and make the first few turns by
hand. If the screw is still difficult (as when us-
ing very hard woods) try using a lubricant such
as soap; liquid soap is usually best.
Keep sufficient pressures on the drill to prevent
the bit turning out of the screw head. The screw
head can easily become damaged making it dif-
ficult to drive it home or even remove it.
HOLE DRILLING
ATTENTION: When attempting to drill a
large diameter hole, it is sometimes best to
start with a smaller drill bit then work up to
the required size. This prevents overloading
the drill.
• Set the tool to the DRILL mode and push the
dual range gear selector to the position "Lo"
to choose low speed.
NOTE: Remember to use a "wood-pecker" ac-
tion on deep holes to allow the swarf to be
ejected from the hole.
If the drill bit snags, switch off immediately to
prevent permanent damage to the drill. Try to
run the drill in reverse to remove the bit.
• Keep the drill in line with the hole. Ideally,
the drill bit should enter at right angles to the
work. If the angle is changed during drilling,
this could cause the bit to snap off blocking the
hole and perhaps causing injury.
• Reduce pressure as the drill is about to break
through the item being drilled.
• Don't force the drill, let it work at its own
pace.
• Keep the drill bit sharp.
