RIDGID R82008 Manual Del Operador página 8

OPERATION
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.
kEYLESS CHUCk
See Figure 4, page 11.
The drill has a keyless chuck to tighten or release drill bits
in the chuck jaws. Grasp and hold the collar of the chuck
with one hand. Rotate the chuck body with your other hand.
The arrows on the chuck indicate which direction to rotate
the chuck body in order to LOCk (tighten) or UNLOCk
(release) the drill bit.
wARNING:
Do not hold the chuck body with one hand and use
the power of the drill to tighten the chuck jaws on
the drill bit. The chuck body 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.
TwO-SPEED GEAR TRAIN
See Figure 5, page 11.
The drill has a two-speed gear train designed for drilling or
driving at LO (1) or HI (2) speeds. A slide switch is located on
top of the drill to select either LO (1) or HI (2) speed. When
using drill in the LO (1) speed range, speed will decrease
and unit will have more power and torque. When using drill
in the HI (2) speed range, speed will increase and unit will
have less power and torque. Use LO (1) speed for high power
and torque applications and HI (2) speed for fast drilling or
driving applications.
NOTE: If you have difficulty changing from one gear range to
the other, turn the chuck by hand until the gears engage.
CAUTION:
Never change gears while the tool is running.
Failure to obey this caution could result in serious
damage to the drill.
ADjUSTAbLE TORqUE CLUTCH
This product is equipped with an adjustable torque clutch
for driving different types of screws into different materials.
The proper setting depends on the type of material and the
size of screw you are using.
ADjUSTING TORqUE
See Figure 5, page 11.
There are eighteen torque indicator settings located on the
front of the drill.
 Rotate the adjusting ring to the desired setting.
• 1 - 3 For driving small screws
• 4 - 7 For driving screws into soft material
• 8 - 11 For driving screws into soft and hard
materials
• 12 - 14 For driving screws into hard wood
• 15 - 18 For driving large screws
INSTALLING bITS
See Figures 4 and 6, page 11.
 Lock the switch trigger by placing the direction of rotation
selector in the center position.
 Open or close the chuck jaws to a point where the opening
is slightly larger than the bit size you intend to use. Also,
raise the front of the drill slightly to keep the bit from falling
out of the chuck jaws.
 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, as shown in figure 8.
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 4, page 11.
 Lock the switch trigger by placing the direction of rotation
selector in the center position.
 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.
CAUTION:
Do not operate switch trigger with middle finger
and index finger extended. This could cause
fingers to contact moving chuck and may result
in a minor injury.
DRILLING
See Figures 7 - 8, page 11.
 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.
 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.
