Trigger Switch & Forward/Reverse Button - Figure D
• The drill is turned ON and OFF by pulling and
releasing the trigger switch (1) shown in Figure
D. 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.
• To select reverse, depress the forward/reverse
control button on the left side of the tool.
• The center position of the control button locks
the tool in the off position. When changing the
position of the control button, be sure the trigger is released.
Adjusting Torque Control - Figure E
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 workpiece
materials require a higher torque setting than small
screws and soft workpiece 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.
Dual Range Gearing - Figure F
The dual range feature of your drill allows you to
shift gears for greater versatility.
• To select low speed, high torque setting (position
1), turn tool off and permit to stop. Slide gear
shifter button (4) away from the chuck.
• To select the high speed, low torque setting
(position 2), turn tool off and permit to stop.
Slide
gear shifter button back toward the chuck.
NOTE: Do not change gears when tool is running. If
you are having trouble changing gears, make sure
that the dual range gear button is either completely
pushed forward or completely pushed back.
Keyless Chuck - Figure G

removed to prevent tool actuation before installing or

counterclockwise direction, as viewed from the
