Forward/Reverse Switch; Adjustable Torque; Inserting And Removing Bits; Adjustable Side Handle - GMC BN18SB Instructions Manual

To stop the drill, release the trigger switch.
Note. You can only change the direction of rotation of the
drill using the forward/reverse switch when the trigger is
NOT depressed.

Forward/reverse switch

The Forward/Reverse Switch
(4) enables you to change the
direction of the motor while the
GB
trigger switch is not depressed.
Drilling uses the forward mode.
The reverse mode is intended for
the removal of screws.

Adjustable torque

This drill is equipped with 20
torque settings plus one drill
setting. These are controlled by
the Torque Collar (2). By rotating
the collar, it is possible to adjust
the torque.
This will allow better control
when using the drill as a
screwdriver as it prevents over-
tightening of the screws.
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. Where possible, use a scrap piece
of material to set the torque.

Inserting and removing bits

This drill has a keyless chuck, so a chuck key is not needed
to secure a bit in the drill.
1. To open the chuck, hold the
rear section of the chuck firm
and rotate the front section
in a anti-clockwise direction
sufficient 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 clockwise 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 the front section sharply in an anti-
clockwise direction, sufficient to allow the drill bit to be
removed.

Adjustable side handle

1. Turn the Side Handle Clamp
Knob (6) anti-clockwise to
loosen the collar fully and slip
it over the Chuck (1) onto the
drill.
2. Adjust the position of the
Side Handle (5) to suit the
application and tighten the
Side Handle Clamp Knob (6)
to secure it in place.
