The variable speed switch enables you to select the best
speed for a particular application. The further you squeeze
the trigger, the faster the tool will operate. 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. A)
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 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.
Worklight (Fig. A)
There is a worklight (8) located under the torque
adjustment collar (3). 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. A)
Turn (11) to screw symbol. The torque adjustment collar (3)
is clearly marked with numbers and a drill bit symbol.The
collar should be rotated until the desired setting is located
at the top of the tool. 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 function collar (11)
to drill bit position.
Note: When using the drill/driver for drilling holes, be sure that
the function collar is set so the figure of the drill is aligned with
the center line on the top ofthe tool. Failure to do this will allow
the clutch to slip while attempting to drill.
Dual range gearing (Fig. A and D)
The dual range feature of your driver/drill allows you to
shift gears for greater versatility.
To select the low speed, high torque setting, turn the tool
off and permit to stop. Slide the gear shifter (4) forward
(towards the chuck). To select the high speed, low torque
setting, turn the tool off and permit to stop. Slide the gear
shifter back (away from chuck).
Note: Do not change gears when the tool is running. If you
are having trouble changing gears, make sure that the dual
range gear shifter is either completely pushed forward
or completely pushed back.
Keyless single sleeve chuck (Fig. E)
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. Rotate
the sleeve counterclockwise far enough to accept
the desired accessory.
3. Insert the accessory about 19mm (3/4") into the chuck
and tighten securely by rotating the chuck sleeve
clockwise with one hand while holding the tool with
the other. Your tool is equipped with an automatic
spindle lock mechanism. This allows you to open
and close the chuck with one hand.
4. To release the accessory, repeat step 2 above.
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 result. Always lock
off trigger switch when changing accessories. Be sure to
tighten chuck with one hand on the chuck sleeve and one
hand holding the tool for maximum tightness.
Chuck removal (Fig. F)
Turn the adjustment collar to the "drill" position and gear
shifter to position 1 (low speed). Tighten the chuck around
the shorter end of a hex key (not supplied) of 6.35mm
(1/4") or greater size. Using a wooden mallet or similar
object, strike the longer end in the clockwise direction,
as shown. This will loosen the screw inside the chuck.
Open chuck jaws fully, insert screwdriver (or Torx tool if
required) into front of chuck between jaws to engage screw
head. Remove screw by turning clockwise (left-hand-thread).
Place hex key in chuck and tighten, as shown in Fig. F.
Using a wooden mallet or similar object, strike key sharply
in the counterclockwise direction. This will loosen the
chuck so that it can be unscrewed by hand.
Chuck installation (Fig. G)
Screw the chuck on by hand as far as it will go and insert
screw (left-hand thread). Tighten screw securely. Tighten the
chuck around the shorter end of a 6.35mm (1/4") or larger
hex key (not supplied) strike the longer end in the clockwise
direction with a wooden mallet, as shown. Tighten the screw
once again by turning in a counterclockwise direction.
