Operation - RIDGID R7121 Manuel D'utilisation

OPERATION

WARNING:
Do not allow familiarity with products to make you
careless. Remember that a careless fraction of a
second is sufficient to inflict severe injury.
WARNING:
Always wear safety goggles or safety glasses with
side shields when operating products. Failure to
do so could result in objects being thrown inot your
eyes resulting in possible serious injury
APPLICATIONS
You may use the product for the purposes listed below:
 Drilling in wood
 Drilling in both hard and soft metals
 Mixing paints and drywall compounds
SWITCH
See Figure 6, page 14.
To turn the drill ON, depress the switch trigger. Release
the switch trigger to turn the drill OFF.
REVERSIbLE
See Figure 6, page 14.
The direction of chuck rotation is controlled by the rocker-
type switch trigger. For clockwise drilling, depress the lower
half of the switch trigger.
To reverse the direction to counterclockwise (for removing
screws), depress the upper half of the switch trigger.
Release the switch trigger and allow the drill to stop before
changing its direction.
CAUTION:
To prevent gear and motor damage, always allow
the chuck to come to a complete stop before
changing the direction of rotation.
LOCk-ON bUTTON
See Figure 7, page 14.
This tool is equipped with a lock-on feature, which allows
continuous operation for extended periods of time. To
lock-on, depress the switch trigger. Push in and hold the
lock-on button, located beneath the switch trigger, then
release switch trigger. Release lock-on button and the drill
will continue running.
NOTE: This feature applies only to operation in the forward
direction.
To release the lock, depress the switch trigger and
release.
If you have the lock-on feature engaged during use and the
drill becomes disconnected from power supply, disengage
the lock-on feature immediately.
WARNING:
To avoid loss of control or serious personal injury,
when drilling in lock-on mode, keep your hand
positioned on the switch. This will allow you to to
stop the drill immediately in case binding occurs.
DRILLING
See Figures 8 - 9, page 15.
 Attach auxiliary handle (except for very light duty jobs)
 Depress and release the switch trigger to be sure the
drill is in the OFF position before connecting it to power
supply.
 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 source.
 Hold the drill firmly and place the bit at the point to be
drilled.
 Depress the switch trigger to start the drill. Do not lock
the switch ON for jobs where the drill may need to be
stopped suddenly.
 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 drill and
bit 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
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.
