SAFETY WARNINGS AND INSTRUCTIONS
DRILLS
1. Hold drill firmly with one hand on the grip and the
other hand on the bottom of the tool.
2. When attaching accessories in the drill chuck, hand
tighten the keyless chuck firmly.
Warning! Drill may stall (if overloaded or improperly
used) causing a twist. Always expect the stall. Grip the drill
firmly with both hands to control the twisting action and
prevent loss of control which could cause personal injury.
If a stall does occur, release the trigger immediately and
determine the reason for the stall before re-starting.
INSTALLING AND REMOVING THE BATTERY
PACK FROM THE TOOL
Warning! Make certain the lock-off button is engaged
to prevent switch actuation before removing or installing
battery.
To install battery pack
Insert battery pack into tool, until an audible click is heard
(Fig. C).
To remove battery pack
Depress the battery release button as shown in Fig. D
and pull battery pack out of tool.
OPERATING INSTRUCTIONS
Trigger switch and reversing button (Fig. E)
f The drill is turned ON and OFF by pulling and
releasing the trigger switch (1). The farther the trigger
is depressed, the higher the speed of the drill.
f A forward/reverse control button (2) determines
the direction of the tool and also serves as
a lock off button.
f To select forward rotation, release the trigger switch
and depress the forward/reverse control button
to the left.
f To select reverse, depress the forward/reverse
control button the opposite direction.
Note: 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.
Torque control (Fig. F)
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.
f For drilling in wood, metal and plastics, set the collar
to the drilling position symbol .
f For screwdriving, set the collar to the desired setting.
If you do not yet know the appropriate setting, proceed
as follows:
a. Set the collar to the lowest torque setting.
b. Tighten the first screw.
c. 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.
Keyless chuck (Fig. G)
Warning! Make certain the lock-off button is engaged
to prevent switch actuation before installing or removing
accessories.
To insert a drill bit or other accessory:
1. Grasp the rear half of the chuck (4) with one hand and
use your other hand to rotate the front half (4a) in
the counterclockwise direction, as viewed from
the chuck end.
2. Insert the bit or other accessory fully into the chuck,
and tighten securely by holding the rear half of the
chuck and rotating the front portion in the clockwise
direction as viewed from the chuck end.
Warning! Do not attempt to tighten drill bits (or any
other accessory) by gripping the front part of the chuck
and turning the tool on. Damage to the chuck and personal
injury may occur when changing accessories.
SCREWDRIVING
For driving fasteners, the reversing button should be
pushed to the left. Use reverse (button pushed to the right)
for removing fasteners. When moving from forward to
reverse, or vice versa, always release the trigger switch first.
On board bit storage
A bit storage slot (8) is built-in to the area just behind the
battery pack.
DRILLING
f Use sharp drill bits only.
f Support and secure work properly, as instructed in the
"Safety Instructions".
f Use appropriate and required safety equipment, as
instructed in the "Safety Instructions".
f Secure and maintain work area, as instructed in the
"Safety Instructions".
f Run the drill very slowly, using light pressure, until
the hole is started enough to keep the drill bit from
slipping out of it.
f Apply pressure in a straight line with the bit. Use
enough pressure to keep the bit biting but not so much
as to stall the motor or deflect the bit.
