Adjusting Torque; Led Light - Ryobi PSBCK01K Manual Del Operador

ADJUSTING TORQUE

See Figure 6, page 11 (PSBDD01).
Rotate the adjustment ring to the proper torque setting for
the type of material and size of screw you are using.
• 1 - 4 For driving small screws
• 5 - 8 For driving screws into soft material
• 9 - 12 For driving screws into soft and hard
materials
• 13 - 16 For driving screws into hard wood
• 17 - 23 For driving large screws
• For heavy drilling

LED LIGHT

See Figure 7, page 11 (PSBDD01).
The LED light, located on the front of the tool base, illuminates
when the switch trigger is depressed.
If the drill is not in use, the time-out feature will cause the
light to start fading and then shut off.
The LED light illuminates only when there is a charged battery
pack in the tool.
DRILLING/DRIVING SCREWS
See Figure 7, page 11 (PSBDD01).
 Check the direction of rotation selector for the correct
setting (forward or reverse).
 Use low (1) speed for high torque applications and
high (2) speed for fast drilling or driving applications.
Refer to Two-Speed Gear Train and Adjusting Torque.
 Secure the workpiece in a vise or with clamps to keep it
from turning as the bit rotates.
 Hold the drill firmly and place the bit at the point to be
drilled, or where the screw is to be driven.
WARNING:
Do not drive a screw where there is likely to be hidden
wiring behind the surface. Contact with a "live" wire will
make exposed metal parts of the tool "live" and possibly
shock the operator. If you must drive a screw where hid-
den wire may be present, always hold tool by insulated
gripping surfaces (handle) when performing the operation
to prevent a shock to the operator.
 Depress the switch trigger to start the drill.
OPERATION
 Move the bit into the workpiece, applying only enough
pressure to keep the bit cutting or driving the screw. Do
not force the drill or apply side pressure to elongate a
hole. Let the tool do the work.
WARNING:
When drilling, be prepared for binding at 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 control when breaking through material. If
not prepared, this loss of control can result in possible
serious injury.
 With hard, smooth surfaces, use a center punch to mark
the desired hole location. This will prevent the bit from
slipping off-center as the hole is started.
 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.
WOOD AND METAL DRILLING
For maximum performance, use high speed steel bits for
wood or metal drilling. Select drilling mode. Begin drilling
at a very low speed to prevent the bit from slipping off the
starting point.
Wood Drilling
 Increase the speed as the drill bit bites into the material.
 When drilling through-holes, place a block of wood behind
the workpiece to prevent ragged or splintered edges on
the back side of the hole.
Metal and Steel Drilling
 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.
 Maintain a speed and pressure which allows cutting
without overheating the bit. Applying too much pressure
will:
• Overheat the drill;
• Wear the bearings;
• Bend or burn bits; and
• Produce off-center or irregular-shaped holes.
 When drilling large holes in metal, start with a small bit,
then finish with a larger bit.
