OPERATION
BIT STORAGE
See Figure 8.
When not in use, bits provided with the drill can be placed in
the storage area located on the top of motor housing.
MAG TRAY™
See Figure 9.
The magnetic tray conveniently stores screws or other
small parts.
INSTALLING BITS
See Figure 10 - 11.
n
Lock the switch trigger by placing the direction of rota-
tion selector in the center position.
n
Open or close the chuck jaws to a point where the
opening is slightly larger than the bit size you intend
to use. Also, raise the front of the drill slightly to keep
the bit from falling out of the chuck jaws.
n
Insert the drill bit.
n
Tighten the chuck jaws on the drill bit.
WARNING
Make sure to insert the drill bit straight into the
chuck jaws. Do not insert the drill bit into the chuck
jaws at an angle then tighten, as shown in fi gure
12. This could cause the drill bit to be thrown from
the drill, resulting in possible serious personal injury
or damage to the chuck.
n
Rotate the chuck clockwise to tighten the chuck jaws
securely on the bit.
NOTE:
Rotate the chuck body in the direction of the
arrow
marked
LOCK
to tighten the chuck jaws. Do not
use a wrench to tighten or loosen the chuck jaws.
REMOVING BITS
See Figure 10.
n
Lock the switch trigger by placing the direction of rota-
tion selector in the center position.
n
Rotate the chuck sleeve clockwise to open the chuck
jaws.
NOTE:
Rotate the chuck body in the direction of the
arrow marked
UNLOCK
to loosen the chuck jaws.
Do not use a wrench to tighten or loosen the chuck
jaws.
n
Remove the drill bit.
DRILLING
See Figure 12 - 13.
Levels are located on the top and end of the motor housing
to help keep the drill bit level during use.
n
Check the direction of rotation selector for the correct
setting (forward or reverse).
n
Secure the material to be drilled in a vise or with clamps
to keep it from turning as the drill bit rotates.
n
Hold the drill fi rmly and place the bit at the point to be
drilled.
n
Depress the switch trigger to start the drill.
n
Move the drill bit into the workpiece, applying only
enough pressure to keep the bit cutting. Do not force
the drill or apply side pressure to elongate a hole. Let
the tool do the work.
WARNING
Be prepared for binding at bit breakthrough. When
these situations occur, the drill has a tendency to
grab and kick in the opposite direction and could
cause loss of control when breaking through mate-
rial. If not prepared, this loss of control can result
in possible serious injury.
n
When drilling hard, smooth surfaces, use a center
punch to mark the desired hole location. This will
prevent the drill bit from slipping off-center as the hole
is started.
n
When drilling metals, use a light oil on the drill bit to
keep it from overheating. The oil will prolong the life
of the bit and increase the drilling action.
n
If the bit jams in the workpiece or if the drill stalls,
stop the tool immediately. Remove the bit from the
workpiece and determine the reason for jamming.
NOTE:
This drill has an electric brake. When the switch
trigger is released, the chuck stops turning. When the
brake is functioning properly, sparks will be visible through
the vent slots on the housing. This is normal and is the
action of the brake.
MAINTENANCE
WARNING
When servicing, use only identical Ryobi replace-
ment parts. Use of any other parts may create a
hazard or cause product damage.
