DRILLING
See Figure 11. OVERLOAD
Yourdrill has a built-inoverload protsctor to protect
the motor during overloading or prolonged use. The
overloed protector automatically activates to break the
circuit.When this occurs, allow your drillto cool a few
seconds before resuming operation.
CHUCK REMOVAL
See Figures 12, 13, and 14.
The chuck must be removed inorder to use some
accessories. To remove:
•Lock switch trigger on your drill by placing the
direction of rotation selector in center position.
See Figure 2.
•Inserta 5/16 inch or larger hex key wrench intothe
chuckof yourdrilland tightenthe chuck jaws
securely.
•Tap the hex key wrench sharply with a mallet in a
clockwise direction. See Figure 13. This will
loosen the screw in the chuck for easy removal.

When ddllinghard smooth surfaces use a canter punch
to mark desired hole location.This will prevent the ddll
bitfrom slippingoff center as the hole is started. How-
ever, the lowspeed feature allows startingholes without
center punching if desired. To accomplish this,simply
operateyour drill at a lowspeed untilthe hole is started.
The matedal to be ddlledshould be secured in avise or
withclamps tokeep itfrom tuming as the ddllbit rotates.
Holdtool firmly and place thebit at the point to be ddlled.
Depressthe switchtrigger to start tool.
Move the ddnbit into the workpisce applying only
enough pressure to keep the bit cutting. Do not force or
applyside pressureto elongate a hole.
WARNING: Be prepared for binding or bit
breakthrough. When these situations occur, drill
has a tendency to grab and kick opposite to the
direction of rotation and could cause loss of
controlwhen breakingthrough material. If not
prepared, this loss of control can result in
possible serious injury.
When drilling metals, use a light oil on the ddll bit to
keep it from overheating. The oil will prolong the life of
the bitand increase the drilling action.
If the bitjams in workpiece or if the drill stalls, release
switchtrigger immediately. Remove the bit from the
workpiece and determine the reason forjamming.
