RIDGID R8611504 Manual Del Operador página 7

OPERATION
 Rotate the chuck body to close and tighten the chuck
jaws.
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.
 To remove bits, lock the switch trigger and open the
chuck jaws.
 The bit provided with the drill can be placed in the storage
area, located on the rear base of the drill.
LED LIGHT
See Figure 7, page 11.
The LED light, located on the front of the tool base,
illuminates when either the switch trigger or grip light switch
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.
TWO-SPEED GEAR TRAIN
See Figure 8, page 11.
 Select LO (1) speed for applications requiring higher
power and torque.
 Select HI (2) speed for fast drilling or driving applications.
NOTE: 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.
NOTICE:
Never change speeds while the tool is running.
Failure to obey this caution may result in serious
damage to the drill.
ADJUSTING TORQUE
See Figure 9, page 11.
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 - 24 For driving large screws
SELECTING DRILL, DRIVE, OR HAMMER MODE
See Figure 10, page 12.
The mode selector allows you to quickly switch from drill
mode to drive or hammer mode.
Drill mode should be used for drilling and other heavy duty
applications. Drive mode should be used for driving screws.
Hammer mode should be used for hammer drilling.
Select the option that best matches the type of bit, fastener,
and material you will be using.
 Choose your application.
 Choose the correct speed: LO (1) or HI (2).
 Choose the correct mode: drill, drive or hammer.
NOTE: The hammer drill has not been designed for reverse
hammering.
Use carbide-tipped bits and select hammer mode when
drilling in hard materials such as brick, tile, concrete, etc.
Select drill mode when drilling with twist drills, hole saws,
etc., in soft materials.
NOTE: When drilling in hammer mode, it is advisable to use
LO (1) speed.
DRILLING/DRIVING SCREWS
See Figure 11, page 12.
WARNING:
Always use the auxiliary handle when using this
tool to help resist torque reactions. Binding or
stalling of this product could lead to serious
personal injury.
 Install the auxiliary handle.
 Check the direction of rotation selector for the correct
setting (forward or reverse).
 Use LO (1) speed for high torque applications and
HI (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 hidden wire could be
present, always hold tool by insulated gripping
surfaces (handle) when performing the operation
to prevent a shock to the operator.
