Two-Speed Gearbox; Installing And Removing Bits - 909 T12 Series Manual

Two-speed gearbox

The high/low speed range selector allows you to
select the gear with the optimum speed and torque to
suit the application.
To select the LOW gear, 0-440 RPM (low
speed, high torque setting), push the gear
selector downward (toward the battery).
The word LO will be displayed.
To select the HIGH gear, 0-1450 RPM (high
speed, low torque setting), push the gear
selector upward (toward to the top of the
drill). The word HI will be displayed.
CAUTION!
Do not change between LO gear and
HI gear while the tool is running. Failure to obey this
caution could result in serious damage to the drill.
Adjustable torque control
This drill is equipped with 17
torque clutch positions plus one
drill mode which are controlled
by the torque clutch.
All of the torque
settings are clearly identified on the torque
collar. To adjust the torque setting you rotate
the torque collar. The higher the number, the
(fig. H)
higher the torque setting.
Controlling the torque allows for better control when using the
drill on specific screwing tasks and prevents over-fastening and
over-tightening.
For drilling, always use the drill mode by aligning the
drill icon with the triangular indicator on the front
face of the drill near the torque collar.
The proper setting will depend on the type of material and the size of
the screw that is being used. Select the option that best matches the
type of bit, the fastener, and the type of material.
Drill mode
Select the drill mode for drilling and other heavy-duty
applications, especially for hard wood and metal.

To select the drill mode, rotate the torque clutch until the drill icon is
aligned with the triangular indicator on the front face of the drill near
the torque clutch.
Keyless chuck
WARNING!
Do not hold the body of the chuck with
one hand while using the power of the drill to tighten the
jaws of the chuck on the drill bit. The body of the chuck
could slip in your hand, or your hand could slip and come
into contact with the rotating bit. This could cause an
accident and result in serious
personal injury.
The arrows on the chuck indicate
G
the direction of rotation of the
body of the chuck to GRIP (tighten)
or RELEASE the jaws of the chuck
on the drill bit. (fig. I)

Installing and removing bits

Do not insert and remove bits while the tool is
•
activated.
Make sure the battery pack is removed or the tool is
in the sleep mode when inserting and remove bits.
Open the chuck by unscrewing it in a counter-
•
clockwise direction while holding the drill.
sufficiently enough to allow the drill bit to enter the jaws of the
chuck.
H
• Ensure the drill bit is fully inserted, so that the
chuck jaws grip the straight section of the bit.
• Rotate the chuck clockwise until the jaws tighten on
the drill bit.
The collar of the chuck needs to be tightened firmly
to ensure the drill bit is held securely.
• To remove the drill bit, rotate the chuck in a counter-
clockwise direction, sufficiently enough to allow the
drill bit to be removed.
Note:
This device is fitted with a spindle lock and the chuck is a
one-handed operation.
WARNING:
Be sure to insert the drill bit straight into
the jaws of the chuck. Do not tighten the jaws of the chuck
with the drill bit inserted at an angle. Doing so could cause
the drill bit to be thrown from the drill, which could result
in serious personal injury or damage to the chuck.
