RIDGID R862311 Operator's Manual page 9

OPERATION
 Depress the switch trigger to start the drill.
 Move the bit into the workpiece, applying only enough
pressure to keep the bit cutting or driving the screw. Do
not force the drill or apply side pressure to elongate a
hole. Let the tool do the work.
WARNING:
When drilling, 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 bit
from slipping off-center as the hole is started.
 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.
NOTE: This drill has an electric brake. When the switch trig-
ger is released, the chuck stops turning.
WOOD AND METAL DRILLING
For maximum performance, use high speed steel bits for
wood or metal drilling. Select drilling mode. Begin drilling
at a very low speed to prevent the bit from slipping off the
starting point.
Wood Drilling
 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.
Metal and Steel Drilling
 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.
 Maintain a speed and pressure which allows cutting
without overheating the bit. Applying too much pressure
will:
• Overheat the drill;
• Wear the bearings;
• Bend or burn bits; and
• Produce off-center or irregular-shaped holes.
 When drilling large holes in metal, start with a small bit,
then finish with a larger bit.
MASONRY DRILLING
For maximum performance, use carbide-tipped masonry
impact bits or designated hammer drill bits when drilling
holes in brick, tile, concrete, etc. Select hammer mode.
 Apply light pressure at medium speed for best results in
brick.
 Apply additional pressure for hard materials such as
concrete.
 When drilling holes in tile, practice on a scrap piece to
determine the best speed and pressure. Begin drilling at
a very low speed to prevent the bit from slipping off the
starting point.
R862311 IMPACT DRIVER
INSTALLING / REMOVING BITS
See Figure 4, page 13 (R862311).
 To install bits, remove the battery pack from the tool.
 Push the bit into the chuck until it clicks into place.
NOTE: If the bit does not insert easily into the chuck, pull
the chuck forward and reinsert the bit.
 Pull on the bit to make sure it is secured in the chuck.
There may be some play in the installed bit; this is normal.
NOTE: Use only impact quality bits with a locking groove.
WARNING:
Make sure the bit is secured in the chuck before
using the impact driver. Failure to do so could
cause serious personal injury.
 To remove bits, remove the battery pack from the tool.
 With the nose of the tool pointed away from you, pull the
chuck away from the driver.
 The bit will eject from the chuck.
SPEED/TORQUE SELECTOR
See Figure 5, page 13 (R862311).
The speed and torque of the impact driver can be changed
for various applications. Press the speed/torque selector
to cycle between LOW (1) speed, MEDIUM (2) speed, and
HIGH (3) speed.
NOTICE:
Never change modes while the tool is running.
Doing so may result in serious damage to the tool.
LED LIGHT
The LED light located on the front of the tool base illuminates
when the switch trigger is depressed.
If the tool is not in use, the time-out feature will cause the
lights to start fading and then shut off.
The LED light illuminates only when there is a charged battery
pack in the tool.
