hand on the chuck sleeve and one hand holding the tool for 
maximum tightness.
Chuck removal (Fig. F)
Turn the adjustment collar to the “drill” position and gear 
shifter to position 1 (low speed). Tighten the chuck around 
the shorter end of a hex key (not supplied) of 6.35mm (1/4”) 
or greater size. Using a wooden mallet or similar object, 
strike the longer end in the clockwise direction, as shown. 
This will loosen the screw inside the chuck.
Open chuck jaws fully, insert screwdriver (or Torx tool if 
required) into front of chuck between jaws to engage screw 
head. Remove screw by turning clockwise (left-hand-thread). 
Place hex key in chuck and tighten, as shown in Fig. F. 
Using a wooden mallet or similar object, strike key sharply 
in the counterclockwise direction. This will loosen the chuck 
so that it can be unscrewed by hand.
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 6.35mm (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.
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.
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 dust mask 
when performing this procedure.
 Warning! Never use solvents or other harsh 
chemicals for cleaning the non-metallic parts of
