the surrounding air temperature is approximately 65°F
- 75°F (18°- 24°C). d. If charging problems persist, take
the tool, battery pack and charger to your local Stanley
Fat Max service center.

desire with no adverse affect on the battery pack.
Installing and Removing the Battery Pack
from the tool
Warning!
Make certain the lock-off button is engaged to

• Depress the battery release button (7) as shown in figure
B and pull battery pack out of tool.
Trigger switch & forward/reverse button -
figure C
• The drill is turned ON and OFF by pulling and releasing
the trigger switch (1) shown in figure C. The farther the
trigger is depressed, the higher the speed of the drill.
• A forward/reverse control button (2) determines the
rotational direction of the tool and also serves as a lock
off button.
• To select forward rotation, release the trigger switch and
depress the forward/reverse control button on the right
side of the tool.

This tool is fitted with a torque adjustment collar (3) to select
the operating mode and to set the torque for tightening
screws. Large screws and hard work piece materials require
a higher torque setting than small screws and soft work piece
materials.

• For drilling in wood, metal and plastics, set the collar to
the drilling position symbol.
• For screwdriving, set the collar to the desired setting. If
you do not yet know the appropriate setting, proceed as
follows:
• Set the collar to the lowest torque setting.
• Tighten the first screw.
• If the clutch ratchets before the desired result is
achieved, increase the collar setting and continue
tightening the screw.
• Repeat until you reach the correct setting.
• Use this setting for the remaining screws.
