Chuck installation (FIG. G)
Screw the chuck on by hand as far as it will go and insert screw 
(left-hand thread). Tighten screw securely. Tighten the chuck 
around the shorter end of a 6.35 mm (1/4") or larger hex key 
(not supplied) strike the longer end in the clockwise direction 
with a wooden mallet, as shown. Tighten the screw once again 
by turning in a counterclockwise direction.
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.
  •   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.
  • 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.
  •   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.
  •   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 
DAMAG
E THE DRILL.
  • To minimize stalling or breaking through the material, 
reduce pressure on drill and ease the bit through the last 
fractional part of the hole.
 
•
Keep the motor running when pulling the bit back out of a 
drilled hole. This will help prevent jamming.
 
•
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.
 
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 power 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.
 
 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.
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 dust mask 
when performing this procedure.
