DUST AND SWARF
A correctly fitted dust mask, suitable for the activity
and in accordance to the relevant standard must be
worn. Swarf produced by metal drilling is extremely
sharp. Take precautions when clearing swarf. The
burr left on the hole is also sharp and should be
removed with a suitable tool. Always wear safety
goggles.
WARNING: Drill bit will be hot after use.
INSTALLING AND REMOVING BITS
The drill is fitted with a keyless chuck, this means
that a chuck key is not required to secure the drill
or screwdriver bit.
i. Place the drill bit shoulder into the chuck as far
as it will go.
ii. Tighten the chuck firmly.
Note: Short screwdriver bits need only be inserted
to the depth of the hexagon shank before tighten-
ing chuck by hand.
LED WORK LIGHT
To aid drilling and screwdriving in confined, inade-
quately lit spaces, the LED work light (7) automatically
illuminates when the trigger is activated.
FORWARD/REVERSE SELECTOR
The switch determines the direction of rotation of
the chuck, i.e. clockwise or anticlockwise.
i. Stop the drill and push switch (2) to the left
or right. NOTE: When the direction switch is
pushed to the left, the chuck will rotate clock-
wise. Before operation, check that the switch is
set in the required position. Do not change the
direction of rotation until the chuck comes to a
complete stop.
ii. When the drill is not in use move the direction
switch to the neutral position (the middle set-
ting) to lock the trigger out.
TRIGGER
When the trigger is depressed, the chuck will rotate
(provided the direction switch is set in the forward

or reverse position). This trigger switch is electronic
which enables the user to vary the speed continu-
ously. The speed varies according to how far the
trigger switch is depressed. The further it is de-
pressed, the faster the chuck will rotate. The lighter
it is depressed, the slower it will rotate.
TORQUE SELECTION CONTROL
By turning the collar (4) it is possible to adjust the
amount of torque. Settings 1-21 provide a facility
for setting the torque to the required level. For ex-
ample, this means that repetitive driving of screws
of the same size will be driven into the material
to the same torque, thus giving the same fixing
strength, or in the case of countersunk screws,
these will all be driven to the same depth in the
material. The torque control prevents the heads
of small diameter screws being twisted off when
correctly set. By turning the collar (5) it is possible
to switch between rotary drilling, percussion drill-
ing and screwdriving functions. Set the "twist drill"
setting , for rotary drilling/screwdriving, in the
"hammer drill" setting
will come into action. This is intented for drilling
into masonry, etc. Turn the collar to the
to use the drill for screwdriving.
TWO SPEED GEAR BOX
Select a low gear (1) (slower rotational speed and
higher torque) for screwdriving.
Use a high gear (2) (faster rotational speed and low-
er torque) for drilling holes.
HOLDING THE DRILL (image 1 & 2)
The drill casing is designed to be held comfortably
in two ways,
1. By the handle.
2. Or by the in-line support grip.
DRILLING WOOD AND PLASTIC
To prevent splitting around the drill holes on the re-
verse side, place a piece of scrap timber under the
material to be drilled.
DRILLING METAL
Metals such as sheet steel, aluminium and brass may
be drilled. Mark the point to be drilled with a centre
punch to help the drill bit tip to locate. A drop of oil
on the area will aid cutting and help prolong the life
of the bit.
DRILLING MASONRY
Start drilling at a low speed to prevent the drill bit
from wandering. Once penetration is achieved, fully
depress the trigger to achive maximum speed and
hammer power.
SCREWDRIVING
To prevent slip or damage to the screw head, match
the screwdriver bit to the screw head size. To remove
screws, move the direction switch to the reversing
position and apply pressure to the screw head and
depress the trigger slowly).
Screwdriver bits are a consumable item. Before drill-
ing check that there are no hidden hazards such as
