Using The Drill; Speed Gearbox - 909 12V2BLI Instruction Manual

Using the drill

Trigger switch
Use the forward/reverse switch
(4) to select the direction of
rotation, then pull the trigger
(3). This trigger switch is an
electronic variable speed control
which enables the user to
vary the speed continuously.
The speed varies according
to how far the trigger switch is
depressed. The further it is depressed the faster the chuck
will rotate and the lighter it is depressed, the slower it will
rotate.
To stop the drill, release the trigger switch.
Note. The variable Speed control fitted to this drill is NOT
intended to be used for long periods of time during the
operation of the task being performed. Use the variable
speed to start drilling and screwing tasks, and then fully
depress the trigger once the task has started.
CAUTION. Extended use of the variable speed under load will
overload and then permanently damage the speed control.
Adjustable torque
This drill is equipped with 24
torque settings, plus one drill
setting which are controlled
by the torque collar (2). All of
the torque settings are clearly
identified on the torque collar. To
adjust the torque setting, rotate
the torque collar. Rotate the
torque collar to a higher number
to increase the torque setting and rotate it to a lower
number to decrease the torque setting.
Controlling the torque allows for better control when using
the drill on specific tasks and prevents over-fastening and
over-tightening.
For drilling, always use the
Drill position by aligning the
Drill symbol with the triangular
indicator on the front face of the
drill near the torque collar.
For setting the torque position,
select a low setting on the torque
collar and align the selected
symbol with the triangular
indicator on the top of the drill. Increase gradually to set the
correct torque. It is better to use a scrap piece of material if
possible to set the torque.
Forward/reverse switch
Note. You can only change
the direction of rotation of the
drill using the forward/reverse
switch when the trigger is NOT
depressed.
This switch (4) will allow you to
change the direction of the motor
while the trigger switch is not depressed.
Drilling uses the forward mode. The reverse mode is
intended for the removal of screws and assisting to remove
jammed drill bits.

2 Speed gearbox

The 2 Speed Gearbox allows you
to select a gear with the optimum
speed and torque to suit the
application.
Note. When changing the drill
selector, ensure the drill is not
operating.
To select the LOW gear (low speed, high torque setting),
push the gear selector (9) backward, towards the back of
the drill. The symbol I will be displayed.
