RIDGID R7001 Manual Del Operador página 9

OPERATION
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 5. This
could cause the drill bit to be thrown from the drill,
resulting in possible serious personal injury or dam-
age to the chuck.
 Tighten the chuck jaws securely on the bit.
NOTE: Rotate the chuck body in the direction of the ar-
row marked GRIP to close the chuck jaws. Do not use a
wrench to tighten or loosen the chuck jaws.
TO REMOVE BITS
 Unplug the drill.
 Open the chuck jaws.
NOTE: Rotate the chuck body in the direction of the ar-
row marked RELEASE 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 6, page 13.
This drill is equipped with a lock-on feature, which is conve-
nient 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.
DRILLING
See Figures 7 - 8, page 13.
 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, drill has a tendency to grab
and kick opposite to the direction of rotation and
could cause loss of control when breaking through
materials. 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.
WOOD DRILLING
For maximum performance, use high speed steel bits for
wood drilling.
 Begin drilling at a very low speed to prevent the bit from
slipping off the starting point. 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.
