Variable Speed Switch (Fig. 2)
To turn the tool on, squeeze the trigger switch (A). To turn the tool off,
release the trigger switch. Your tool is equipped with a brake. The
chuck will stop as soon as the trigger switch is fully released.
The variable speed switch enables you to select the best speed for a
particular application. The farther you squeeze the trigger, the faster
the tool will operate. Use lower speeds for starting holes without a cen-
terpunch, drilling in metals or plastics, driving screws and drilling
ceramics, or in any application requiring high torque. Higher speeds
are better for drilling in wood, wood compositions and for using abra-
sive and polishing accessories. For maximum tool life, use variable
speed only for starting holes or fasteners.
NOTE: Continuous use in variable speed range is not recommended.
It may damage the switch and should be avoided.
Forward/Reverse Control Button (Fig. 2)
A forward/reverse control button (B) determines the direction the tool
will spin 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 rota-
B
tion, you may hear a click on start up. This is normal and does not indi-
cate a problem.
Torque Adjustment Collar (Fig. 3)
Your tool has an adjustable torque screwdriver mechanism for driving
and removing a wide array of fastener shapes and sizes and in some
models, a hammer mechanism for
drilling into masonry. Circling the collar
A
(C) are numbers, a drill bit symbol, and
in some models, and a hammer symbol.
These numbers are used to set the
clutch to deliver a torque range. The
higher the number on the collar, the
higher the torque and the larger the fas-
tener which can be driven. To select any
of the numbers, rotate until the desired
number aligns with the arrow.
Three Speed Gearing (Fig. 3)
The three speed feature of your tool allows you to shift gears for greater
versatility. To select speed 1 (highest torque setting), turn the tool off and
permit it to stop. Slide the gear shifter (D) all the way to the left. Speed 2
(middle torque and speed setting) is in the middle position. Speed 3
(highest speed setting) is to the right. NOTE: Do not change gears when
the tool is running. Always allow the drill to come to a complete stop
before changing gears. If you have trouble changing gears, make sure
that the gear shifter is engaged in one of the three speed settings.
Keyless Single Sleeve Chuck (Fig. 4)
Your tool features a keyless chuck with one rotating sleeve for one-
handed operation of the chuck. To insert a drill bit or other accessory,
follow these steps.
1. Lock the trigger in the OFF position as previously described.
2. Grasp the black sleeve of the chuck with one hand and use the
other hand to secure the tool as shown in Figure 4. Rotate the
