Forward/Reverse Control Button (Fig. 2)
A forward/reverse control button (B) 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 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.
NOTE: The first time the tool is run after changing the direction of rotation,
you may hear a click on start up. This is normal and does not indicate a
problem.
Worklights (Fig. 2)
There are three worklights (H) located around the chuck collar (D). The
worklight will be activated when the trigger switch is squeezed.
NOTE: The worklight is for lighting the immediate work surface and is
not intended to be used as a flashlight.
Torque Adjustment Collar (Fig. 2)
The torque adjustment collar (C) is clearly marked with numbers and
the max position.The collar should be rotated until the desired setting is
located at the top of the tool (Fig. 2). Locators are provided in the collar
to eliminate the guess work when selecting fastening torque. The higher
the number on the collar, the higher the torque and the larger the fastener
which can be driven. To lock the clutch for drilling operations, move to
the max position.
Quick-Release Chuck (Fig. 2, 4)
NOTE: The chuck accepts 1/4" (6.35mm) hex accessories and 1"
(25.4 mm) bit tips only.
Place the forward/reverse button (B) in the locked off (center) position
or remove battery pack before changing accessories.
The bit shown in Figure 4 is typical of the bits for use in the quick-
release chuck with a groove (J) which is required to hold the bit firmly.
To install an accessory, fully insert the accessory. The accessory is
locked into place.
To remove an accessory, pull the chuck collar (D) away from the front
of the tool. Remove the accessory and release the collar.
Screwdriver Mode
Select the desired torque number using the torque
adjustment collar (C) on the top of tool.
Insert the desired fastener accessory into the chuck
(D) as you would any screwdriver bit. Make a few
practice runs in scrap or unseen areas to determine
the proper position of the torque adjustment collar (C).
Drilling Mode
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.
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 (C) to the max position symbol for drilling.
1. Use hex shank drill bits only.
2. Always apply pressure in a straight line with the bit. Use enough
pressure to keep the bit biting, but do not push hard enough to
stall the motor or deflect the bit.
