Lock-On Button; Adjusting Torque - Ryobi D47C Manuel D'utilisation

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 figure 6. This could
cause the drill bit to be thrown from the drill, resulting in
possible serious personal injury or damage to the
chuck.
 Tighten the chuck jaws securely on the bit.
NOTE: Rotate the chuck body in the direction of the
arrow marked LOCK to close the chuck jaws. Do not use
a wrench to tighten or loosen the chuck jaws.
REMOVING BITS
See Figure 5, page 12.
 Unplug the drill.
 Open the chuck jaws.
NOTE: Rotate the chuck body in the direction of the arrow
marked UNLOCK to open the chuck jaws. Do not use a
wrench to tighten or loosen the chuck jaws.
 Remove the drill bit.

LOCK-ON BUTTON

See Figure 7, page 13.
This drill is equipped with a lock-on feature, which is
convenient for continuous drilling for extended periods of
time. To lock-on:
 Depress the switch trigger.
 Push in and hold the lock-on button, located on the side
of the handle.
 Release the switch trigger.
 Release the lock-on button and the drill will continue
running.
 To release the lock, depress and release the switch trigger.
If the lock-on feature is engaged during use and the drill
becomes disconnected from the power supply, disengage
the lock-on feature immediately.
WARNING:
Before connecting the drill to a power supply source,
always check to be sure it is not in lock-on position
(depress and release the switch trigger). Failure to ensure
that it is not locked-on could result in accidental starting
of the drill resulting in possible serious injury. Do not lock
the switch trigger in applications where the drill may need
to be suddenly stopped.
ADJUSTABLE TORQUE CLUTCH
See Figure 8, page 13.
This product is equipped with an adjustable torque
clutch for driving different types of screws into different
OPERATION
materials. The proper setting depends on the type of material
and the size of screw you are using.

ADJUSTING TORQUE

See Figure 8, page 13.
There are twenty-four torque indicator settings located on
the front of the drill.
 Rotate the adjusting ring to the desired setting.
• 1 - 4
• 5 - 8
• 9 - 12
• 13 - 16 For driving screws into hard wood
• 17 - 23 For driving large screws

DRILLING
See Figure 9, page 13.
A level is located on the top of the motor housing to help
keep the drill bit level during use.
 Depress and release the switch trigger to be sure the drill
is in the OFF position before connecting it to a power
supply.
 Check the direction of rotation selector for the correct
setting (forward or reverse).
 Secure the material to be drilled in a vise or with clamps
to keep it from turning as the drill bit rotates.
 Plug the drill into power supply. Hold the drill firmly and
place the bit at the point to be drilled.
 Depress the switch trigger to start the drill.
 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 material. If not prepared, this loss
of control can result in possible serious injury.
 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.
 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.
 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.
