Adjusting Torque - Craftsman 315.DD2100 Manual Del Operador

Setting the direction of rotation selector in the OFF (center
lock) position helps reduce the possibility of accidental
starting when not in use.
NOTICE:
To prevent gear damage, always allow the
chuck to come to a complete stop before changing
the direction of rotation.
To stop the drill, release the switch trigger and allow the
chuck to come to a complete stop.
nOTE: The drill will not run unless the direction of rotation
selector is pushed fully to the left or right.
Avoid running the drill at low speeds for extended periods
of time. Running at low speeds under constant usage may
cause the drill to become overheated. If this occurs, cool
the drill by running it without a load and at full speed.
kEYLESS cHuck
See Figure 4, page i.
The drill has a keyless chuck to tighten or release bits in
the chuck jaws. The arrows on the chuck indicate which
direction to rotate the chuck body in order to LOck
(tighten) or unLOck (release) the bit.
WARnIng:
Do not hold the chuck with one hand
and use the power of the drill to tighten the chuck
jaws on the bit. The chuck body could slip in your
hand, or your hand could slip and come in contact
with the rotating bit. This could cause an accident
resulting in serious personal injury.
TWO-SPEED gEAR TRAIn (HI-LO)
See Figure 5, page i.
The drill has a two-speed gear train designed for drilling
or driving at LO (1) or HI (2) speeds. A slide switch is
located on top of the drill to select either LO (1) or HI (2)
speed. When using drill in the LO (1) speed range, speed
will decrease and unit will have more torque. When using
drill in the HI (2) speed range, speed will increase and unit
will have less torque. Use LO (1) speed for high torque
applications and HI (2) speed for fast drilling or driving
applications.
NOTICE:
Never change speeds while the tool is
running. Failure to obey this caution could result in
serious damage to the drill.
OPERATIOn
ADJuSTABLE TORQuE cLuTcH
This product is equipped with an adjustable torque
clutch for driving different types of screws into different
materials. The proper setting depends on the type of
material and the size of screw you are using.

ADJuSTIng TORQuE

See Figure 6, page i.
There are twenty-four torque indicator settings located on
the front of the drill.
 Rotate the adjusting ring to the desired setting.
• 1 - 4
• 5 - 8
• 9 - 12 For driving screws into soft and hard
• 13 - 16 For driving screws into hard wood
• 17 - 20 For driving large screws

InSTALLIng/REmOVIng BITS
See Figures 7 - 9, page ii.
To install:
 Lock the switch trigger by placing the direction of
rotation selector in the center position.
 Open or close the chuck jaws to a point where the
opening is slightly larger than the bit size you intend to
use. Also, raise the front of the drill slightly to keep the
bit from falling out of the chuck jaws.
 Insert the bit.
WARnIng:
the chuck jaws. Do not insert the bit into the chuck
jaws at an angle then tighten, as shown in
figure 8. This could cause the bit to be thrown from
the drill, resulting in possible serious personal injury
or damage to the chuck.
 Tighten the chuck jaws securely on the bit.
nOTE: Rotate the chuck body in the direction of the
arrow marked LOck to close the chuck jaws. Do not
use a wrench to tighten or loosen the chuck jaws.
To remove:
 Lock the switch trigger by placing the direction of
rotation selector in the center position.
 Open the chuck jaws.
nOTE: Rotate the chuck body in the direction of the
arrow marked unLOck to open the chuck jaws. Do
not use a wrench to tighten or loosen the chuck jaws.
 Remove the bit.
 Bits can be placed in the storage area, located on the
base of the drill.
