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.
Adjustable torque
This drill is equipped with 21
torque settings plus one drill
setting which are controlled
by the torque collar (8). All of
the torque settings are clearly
identified on the torque collar.
To adjust the torque setting you
rotate the torque collar. Rotate
the torque collar clockwise to
increase the torque setting and
rotate it anti-clockwise 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 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.
Inserting and removing bits
This drill has a keyless chuck,
which means that a chuck key
is not needed to secure a bit in
the drill.
1. Open the chuck by holding
the rear section of the chuck
firm and rotating the front
section in a anti-clockwise
direction, sufficiently enough
to allow the drill bit required
to fully enter the jaws of the chuck.
2. Ensure the drill bit is fully inserted, so that the chuck
jaws grip the straight section of the bit.
3. Holding the rear section of the chuck firmly, rotate the
front section of the chuck clock-wise until the jaws tighten
on the drill bit. The front section of the chuck needs to be
tightened firmly to ensure the drill bit is held securely.
4. To remove the drill bit, hold the rear section of the chuck
firmly and rotate sharply the front section of the chuck in
a anti-clockwise direction, sufficiently enough to allow the
drill bit to be removed.
