Operating Instructions
Trigger Switch & Forward/Reverse Button - Figure F
The drill is turned ON and OFF by pulling
and releasing the trigger switch (1) shown in
figure F. The farther the trigger is
depressed, the higher the speed of the drill.
A forward/reverse control button (2)
determines the 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.
To select reverse, depress the
forward/reverse control button in the opposite
direction. 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 G
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.
Hammer Action
Your drill has hammer action which is engaged by twisting the torque collar to the
hammer symbol . Use hammer action when drilling in masonry.
Dual Range Gearing - Figure H
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 (towards 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.
