tion of the drill using the forward/reverse switch
when the trigger is NOT depressed.
FORWARD / REVERSE SWITCH
This switch (4) will allow you to change the direc-
tion of the motor while the trigger switch is not de-
pressed.
7
Drilling uses the forward mode. The reverse mode
is intended for the removal of screws.
DRILLING POSITIONS
This symbol indicates the “DRILLING
MODE”. Used for all normal drilling (Wood,
Aluminium, and Steel) in this mode the
clutch is deactivated.
This symbol indicates the “HAMMER
MODE”. This mode will activate hammer
action, whilst drilling. For best results in
hammer mode, set the gear selector to
high gear.
TORQUE ADJUSTMENT / HAMMER
SELECTION COLLAR
By rotating the torque adjustment / hammer selec-
tion collar (2) behind the chuck, it is possible to
adjust the torque to each of 20 settings, or select
hammer action or the drill setting.
The range of 20 torque settings allows better con-
trol when using the drill as a screwdriver as it pre-
vents over-tightening of the screws.
The symbols circling the collar are used to indi-
cate the level of torque. The larger the symbol
on the collar, the higher torque and the larger the
fastener which can be driven. To select any of
the symbols, rotate the collar (2) until the desired
symbol aligns with the arrow head indicator on the
housing.
2 SPEED GEARBOX
The 2 Speed Gearbox allows you to select a gear
with the optimum speed and torque to suit the ap-
plication.
NOTE. When changing the gear selector ensure
the drill is not operating.
1. To select the LOW gear (low speed, high torque
setting), push the gear selector (13) forward,
towards the chuck. The word LOW will be dis-
played.
8
2. To select the HIGH gear (high speed, low torque
setting), push the gear selector (13) back, away
from the chuck. The word HIGH will be dis-
played.
INSERTING AND REMOVING BITS
The drill is fittedwithautospindlelockwhichmeans
if you try and rotate the chuck by hand the spindle
of the drill will automatically lock. This means you
only need to grasp the chuck and rotate the chuck
housing to remove or fit accessories.
This drill has a keyless chuck, hence a chuck key
is not needed to secure a bit in the drill. Always set
the forward/reverse switch (4) to the locked ‘OFF’
position when installing and removing bits. It is
also recommended to remove the battery pack to
avoid unintentional starting.
1. Open the chuck jaws by firmly holding the
chuck housing and rotating the housing in an
anti-clockwise direction. Open the jaws suffi-
ciently so as to fit the desired accessory. 9
2. Ensure the accessory is fully inserted, so that
the jaws of the chuck grip onto the flat section
of the accessory.
3. To firmly clamp the accessory in the chuck,
grasp the chuck housing and rotate the chuck
housing in a clockwise direction. Ensure the bit
is retained firmly or damage to the chuck jaws
can result.
4. To remove the accessory, open the chuck jaws
by firmly holding the chuck housing and rotat-
ing the housing in an anti clockwise direction.
Open the jaws sufficiently so as to remove the
specific accessory.
ADJUSTABLE SIDE HANDLE
1. Turn the side handle clamp knob (6) anti-clock-
wise to loosen the collar fully and slip it over the
chuck (1) onto the drill.
10
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.
DRILLING
Drilling metals
▪ For maximum performance, use high speed
steel bits for metal or steel drilling.
▪ Ensure that the torque adjustment / hammer se-
lection collar (2) is in normal drilling mode.
▪ Begin drilling at a very low speed to prevent the
bit from slipping off the starting point.
▪ Always clamp sheet metal.
▪ Support thin metal with a block of wood to avoid
distorting it.
▪ Use a punch to mark the centre of the hole.
▪ Use a suitable lubricant for the material you are
working on.
