Two-Speed Gearbox - Craftsman NEXTEC 320.30565 Operator's Manual

TWO-SPEED GEARBOX (Fig. 5}
The drill/driver has a two-speed
gearbox for drilling or driving at
LO or HI speeds. A slide switch
is located on the top of the
drill/driver to select either LO or
HI speed.
When using drill/driver in the
LO speed range, the speed will
decrease and the drill/driver will
have more power and torque.
Ann, your question is correct!
I've updated the sentence here.
Use LO speed for high power

and torque applications and HI speed for fast drilling or driving applications.
Use LO speed for starting holes without a center punch, drilling metals or plas-
tic, drilling ceramics, or in applications requiring a higher torque.
HI speed is better for drilling wood and wood composites and for using abrasive
and polishing accessories.
NOTICE: Avoid running the drill/driver at HI speed for extended periods of time.
Running at HI speed under constant usage may cause the drill/driver to become
overheated. If this occurs, cool the drill/driver by running it without a load at LO speed.
_1, CAUTION: Never change gears while the tool is running. Failure to obey this
caution could result in serious damage to the drill/driver.
ADJUSTABLE-TORQUE CLUTCH (Fig. 6)
The Torque clutch can be
adjusted to 17 different set-
tings. The higher the torque drill
setting, the more force the drill/
driver produces to turn an object
in either LO or HI rotation speed.
When using the drill/driver for
different driving applications,
increase or decrease the torque
in order to help prevent dam-
aging screw heads, threads,
workpiece, etc.
Adjust the torque by rotating
the torque-adjustment ring.
The proper setting depends on

the job and the type of bit, fastener, and material you will be using. In general,
use greater torque for larger screws. If the torque is too high, the screws may be
damaged or broken.
