Installing and Removing the Battery Pack

(Fig. G)
nOTE: For best results, make sure your battery pack is
fully charged.
To install the battery pack
1
battery pack with the rails inside the tool's handle and slide
it into the handle until the battery pack is firmly seated in
the tool and ensure that it does not disengage.
To remove the battery pack from the tool, press the release
button 2 and firmly pull the battery pack out of the tool
handle. Insert it into the charger as described in the charger
section of this manual.

Proper Hand Position (Fig. H)

WARNING: To reduce the risk of serious personal
injury, ALWAYS use proper hand position as shown.

WARNING: To reduce the risk of serious personal
injury, ALWAYS hold securely in anticipation of a
sudden reaction.
Proper hand position requires one hand on the main
handle 3 , with the other hand on the top handle
hand on the main handle , with the other hand on the

Drilling

WARNING: TO REDUCE THE RISK OF PERSONAL
INJURY, ALWAYS ensure workpiece is anchored or
clamped firmly. If drilling thin material, use a wood
"back-up" block to prevent damage to the material.
1. Use sharp drill bits only. For WOOD, use twist drill
bits, spade bits, auger bits, self-feed bits, or hole saws.
For METAL, use steel twist drill bits or hole saws. For
CONCRETE, use dry core bits. Do not use water.
2. Always apply pressure in a straight line with the bit. Use
enough pressure to keep drill biting, but do not push
hard enough to stall the motor or deflect the bit.
3. Hold tool firmly with both hands to control the twisting
action of the drill.
4. IF DRILL STALLS, it is usually because it is being
overloaded or improperly used. RELEASE TRIGGER
IMMEDIATELY, remove drill bit from work, and
determine cause of stalling. DO NOT CLICK TRIGGER ON
AND OFF IN AN ATTEMPT TO START A STALLED DRILL
1
— THIS CAN DAMAGE THE DRILL.
5. To minimize stalling or breaking through the material,
reduce pressure on drill and ease the bit through the
last fractional part of the hole.
6. Keep the motor running when pulling the bit back out
of a drilled hole. This will help prevent jamming.
Drilling in Metal
Start drilling with slow speed and increase to full power
while applying firm pressure on the tool. A smooth even
flow of metal chips indicates the proper drilling rate. Use a
cutting lubricant when drilling metals. The exceptions are
cast iron and brass which should be drilled dry.
nOTE: Large [5/16" (8 mm) to 1/2" (13 mm)] holes in steel
can be made easier if a pilot hole [5/32" (4 mm) to 3/16"
(5 mm)] is drilled first.
nOTE: When using a cutting lubricant, be sure not to get
the lubricant on the tool.
Drilling in Wood
Start drilling with slow speed and increase to full power
while applying firm pressure on the tool. Holes in wood can
be made with the same twist drills used for metal. These
bits may overheat unless pulled out frequently to clear chips
from the flutes. Work that is apt to splinter should be backed
up with a block of wood.
Drilling in Masonry

WARNING: Never drill into masonry which is
reinforced such as rebar reinforced concrete.

WARNING: For applications which produce a
considerable amount of dust such as core drilling,
always use an auxiliary dust attachment with an M
Class rated dust extractor such as DWV902M.
Use dry core bits. Keep even force on the drill but not so
much that you crack the brittle material. A smooth, even
flow of dust indicates the proper drilling rate.
Use sharp drill bits only. For masonry, such as brick, cement,
cinder block, etc., use dry diamond core bits
