OPERATION
R86116 HAMMER DRILL
 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. When the brake is
functioning properly, sparks will be visible through the vent
slots on the housing. This is normal and is the action of the
brake.
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.
R86037 IMPACT DRIVER
TRI-BEAM LED LIGHTS
See Figure 4, page 12.
The LED lights around the coupler illuminate when either the
switch trigger or LED grip light switch 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 lights illuminate only when there is a charged bat-
tery pack in the tool.
INSTALLING/REMOVING BITS
See Figure 5, page 12.
 To install bits: Lock the switch trigger and remove the
battery pack.
 Push the bit into the coupler until it clicks into place.
 Pull on the bit to make sure it is secured in the coupler.
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 coupler before
using the impact driver. Failure to do so could
cause serious personal injury.
 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.
 To remove bits: Lock the switch trigger and remove the
battery pack. Point the nose of the tool away from you.
 Pull the coupler away from the driver to eject the bit.
NOTICE:
The impact driver is not designed to be used as
a drill.
SPEED / TORQUE SELECTOR
See Figure 6, page 13.
The speed and torque of the impact driver can be changed
for various applications.
 LOW (1) Speed/Torque (0-750 RPM/450 in. lbs)
 MEDIUM (2) Speed/Torque (0-2000 RPM/1500 in. lbs)
 HIGH (3) Speed/Torque (0-2750 RPM/2250 in. lbs)
NOTICE:
Never change speeds while the tool is running.
Failure to obey this caution could result in serious
damage to the tool.
