Ryobi PSBRA02 Manual Del Operador página 7

NOTE: You might hear a whistling or ringing noise from the
switch during use. Do not be concerned; this is a normal
part of the switch function.
DIRECTION OF ROTATION SELECTOR
(FORWARD/REVERSE/CENTER LOCK)
See Figure 2, page 10.
The direction of bit rotation is reversible and is controlled
by a selector located above the switch trigger. With the drill
held in normal operating position, the direction of rotation
selector should be positioned to the left of the switch trigger
for forward drilling. The drilling direction is reversed when
the selector is to the right of the switch trigger.
Setting the direction of rotation selector in the OFF (center
lock) position helps reduce the possibility of accidental start-
ing when not in use.
CAUTION:
To prevent gear damage, always allow chuck to come
to a complete stop before changing the direction of
rotation.
To stop the drill, release switch trigger and allow the chuck
to come to a complete stop.
NOTE: The drill will not run unless the direction of rotation
selector is pushed fully to the left or right.
Avoid running the drill at low speeds for extended periods
of time. Running at low speeds under constant usage may
cause the drill to become overheated. If this occurs, cool the
drill by running it without a load and at full speed.
INSTALLING/REMOVING BITS
See Figures 3 - 4, page 10.
The arrows on the keyless chuck indicate which direction
to rotate the chuck sleeve to tighten or release the drill bit.
Do not use a wrench to tighten or loosen the chuck jaws.
 To install bits, lock the switch trigger.
 Open or close the chuck jaws until the opening is slightly
larger than the bit size you intend to use.
 Raise the front of the drill slightly and insert 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. This could cause the drill bit to be
thrown from the drill, resulting in possible serious per-
sonal injury or damage to the chuck.
 Rotate the chuck sleeve to close and tighten the chuck
jaws.
OPERATION
WARNING:
Do not hold the chuck sleeve with one hand and use the
power of the drill to tighten the chuck jaws on the drill
bit. The chuck sleeve could slip in your hand, or your
hand could slip and come in contact with the rotating
drill bit. This could cause an accident resulting in serious
personal injury.
 To remove bits, lock the switch trigger and open the
chuck jaws.
INSTALLING/REMOVING BELT HOOK OR BIT
HOLDER
See Figure 5, page 11
The belt hook and bit holder are interchangeable. They may
be installed on either side of the base.
 Align hole in belt hook or bit holder with hole in tool's
base.
 Install screw to secure belt hook or bit holder in place.
 To uninstall, remove screw and then belt hook or bit
holder.
TWO-SPEED GEAR TRAIN
See Figure 6, page 11.
 Select low speed (1) for applications requiring higher
power and torque, such as driving screws and drilling in
metal.
 Select high speed (2) for fast drilling or driving applica-
tions, for drilling in wood or masonry.
NOTICE:
Never change speeds while the tool is running. Failure
to obey this caution could result in serious damage to
the drill.
NOTE: If you have difficulty changing from one speed range
to the other, turn the chuck by hand until the gears engage.
DRILLING/DRIVING SCREWS
See Figure 7, page 11.
 Check the direction of rotation selector for the correct
setting (forward or reverse).
 Secure the workpiece in a vise or with clamps to keep it
from turning as the bit rotates.
 Hold the drill firmly as shown and place the bit at the
point to be drilled, or where the screw is to be driven. If
necessary, use other hand to help brace the tool.
WARNING:
Brace the tool properly before use. This tool produces a
high output torque and without properly bracing the tool
during operation, loss of control may occur resulting in
personal injury.
