Keyless Single Sleeve Chuck (fig. F)
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 19 mm (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.
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.

The dual range feature of your drill allows you to shift speed
for greater versatility. To select low speed, high torque setting
(position 1), turn tool off and permit to stop. Slide gear shifter
button (9) towards the chuck. To select the high speed, low
torque setting (position 2), turn tool off and permit to stop.

If you are having trouble changing gears, make sure that the
dual range gear button is either completely pushed forward or
completely pushed back.
