Drill Operation
Warning! To reduce the risk of serious personal
injury, turn tool off and disconnect tool from power source
before making any adjustments or removing/installing
attachments or accessories.
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.
Turn the collar to the drill bit symbol for drilling. Select the
desired speed/torque range using the gear shifter to match
the speed and torque to the planned operation.
1. Use sharp drill bits only. For WOOD, use twist drill
bits, spade bits, or hole saws. For METAL, use
high-speed steel (HHS) twist drill bits or hole saws.
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.
Warning! The drill may stall if overloaded causing a
sudden twist. Always expect the stall. Grip the drill firmly
with both hands to control the twisting action and avoid
injury.
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 — 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.
7. With variable speed drills there is no need to center
punch the point to be drilled. Use a slow speed to start
the hole and accelerate by squeezing the trigger
harder when the hole is deep enough to drill without
the bit skipping out.
Hammerdrill operation (Fig. D)
1. Turn the collar (11) to the hammerdrill symbol.
2. Select the high speed setting by sliding the selector
forward (towards the chuck).
Important! Use carbidetipped or masonry bits only.
3. Drill with just enough force on the hammer to keep it
from bouncing excessively or "rising" off the bit.
Too much force will cause slower drilling speeds,
overheating and lower drilling rate.
4. Drill straight, keeping the bit at a right angle to
the work. Do not exert side pressure on the bit when
drillling as this will cause clogging of the bit flutes
and a slower drilling speed.
5. When drilling deep holes, if the hammer speed starts
to drop off, pull the bit partially out of the hole with tool
stil running to help clear debris from the hole.
Note: A smooth, even flow of dust from the hole
indicates proper drilling rate.
Operation as a screwdriver
Select the desired speed/torque range using the dual
range gear shifter on the top of tool to match the speed
and torque to the planned operation.
Insert the desired fastener accessory into the chuck as
you would any drill bit. Make a few practice runs in scrap
or unseen areas to determine the proper position of the
clutch collar.

MAINTENANCE
Your STANLEY tool has been designed to operate over
a long period of time with a minimum of maintenance.
Continuous satisfactory operation depends upon proper
tool care and regular cleaning. Your charger does not
require any maintenance apart from regular cleaning.
Warning! To reduce the risk of serious personal
injury, place the forward/reverse button in the lock-off
position or turn tool off and disconnect battery pack
before making any adjustments or removing/installing
attachments or accessories. An accidental start-up can
cause injury.
f Regularly clean the ventilation slots in your tool and
charger using a soft brush or dry cloth.
f Regularly clean the motor housing using a damp
cloth. Do not use any abrasive or solvent-based
cleaner.
f Regularly open the chuck and tap it to remove any
dust from the interior.
f The charger and battery pack are not serviceable.
There are no serviceable parts inside.
Lubrication
Your power tool requires no additional lubrication.
Cleaning
Warning! Blow dirt and dust out of the main housing
with dry air as often as dirt is seen collecting in and around
the air vents. Wear approved eye protection and approved
