 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. 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.
INSTALLING/REMOVING BELT CLIP
See Figure 1, page 11.
The belt clip may be installed on either side of the housing.
 Align the holes in the belt clip with the holes in the housing.
 Install the screws to secure the belt clip in place.
 To uninstall, remove the screws, then remove the belt
clip.
INSTALLING/REMOVING BITS
See Figure 4, page 11.
 To install bits: Lock the switch trigger and remove the
battery pack.
 Slide the coupler forward and hold in position.
 Insert bit straight into coupler.
 Slide the coupler back slowly and release.
NOTE: Use only impact quality bits with a locking groove,
minimum length of 2 in.
OPERATION
P277 DRILL/DRIVER
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 drill-
ing action.
 Maintain a speed and pressure which allows cutting with-
out 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.
P235 IMPACT DRIVER
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.
 Slide the coupler forward and hold in position.
 Pull the bit straight out of the coupler.
