OPERATION
R86008 DRILL-DRIVER
 With 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.
R86034 IMPACT DRIVER
INSTALLING/REMOVING BITS
See Figure 4, page 15.
 To install bits: Lock the switch trigger.
 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.
 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.
CAUTION:
The impact driver is not designed to be used as
a drill.
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.
DRIVING/REMOVING SCREWS
See Figures 5 - 6, page 15.
 Place the direction of rotation selector in the correct posi-
tion for the operation.
 Hold the impact driver with one hand.
 Place the bit on the screw head and slowly depress the
switch trigger. Start the bit slowly for more control.
 As screw is driven, impacting will begin.
NOTE: Operating at low speeds under constant usage may
cause the tool to become overheated. If this occurs, cool
the tool by running it without a load and at full speed.
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 may be present,
always hold tool by insulated gripping surfaces
(handle) when performing the operation to prevent
a shock to the operator.
