Drilling metals
• For maximum performance, use high speed steel bits for metal or
steel drilling.
• Ensure that the torque selection collar (4) 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.
Drilling plastics and plastic coated chipboard
• Use high speed drill bits.
• See drilling wood below
Drilling masonry
• For maximum performance use carbide-tipped masonry impact
bits when drilling holes in brick, tile, concrete etc.
• Turn the torque selector (4) to the drill position.
• Apply light pressure and medium speed for best results in brick.
• Apply additional pressure and high speed for hard materials such
as concrete.
• When drilling holes in tile, practice on a scrap piece to determine
the best speed and pressure.
Drilling wood
• For maximum performance, use high speed steel bits for wood
drilling.
• Ensure that the torque selector (4) is in normal drilling mode.
• Begin drilling at a very low speed to prevent the bit from slipping
off the starting point. Increase the speed as the drill bites into the
material.
• When drilling through holes, place a block of wood behind the
work piece to prevent ragged or splintered edges on the back of
the hole.
WARNING: Never attempt to lock the trigger switch in the on
position, do not lock the trigger on jobs where your hammer
drill may need to be stopped suddenly.
All drilling operations
• Mark off the centre of the hole using a centre punch
or nail.
Use:
For:
Oil
Steel
Turpentine or paraffin
Aluminium
Do not lubricate
Brass, copper or cast iron

Battery charging
Make sure power circuit voltage is the same as that shown on the
charger specification plate. Connect charger to power source. The
green light (A) should light up. This indicates the charger is ready to
begin charging.
Slide battery pack onto the charger adaptor (Fig.2).
Plug the battery and adaptor into the charger unit (Fig.3).
The red light (B) should begin to glow continuously, indicating that
the battery pack is receiving a "fast charge".
After approximately one hour, the "fast charge" indicator red light
(B) should go out indicating that the battery pack is fully charged
and that the charger is now in a "maintenance charge" mode, this is
confirmed by the green light (A) coming on.
Depending on room temperature, line voltage and existing charge
level, initial battery charging may take longer than one hour.
Disconnect charger from power source when not in use.
To obtain the best life for the battery
Never allow the drill to come to a complete stand still before
recharging. The battery should be placed on charge whenever the
battery is noticeably running down or the drill no longer perform a
task it previously performed satisfactorily.
Avoid conducting short charges. Make sure that the battery is fully
charged every time by allowing the charger to complete its full
charging cycle.
Avoid allowing loose items like screws or nails etc. to be stored with
battery packs as these or similar items can short battery packs and
cause a fire or explosion.
Always unplug the charger when not in use and store in a dry
secure place.
Avoid charging or storing your battery in temperatures below 0°C
and above 40°C.
Trigger switch
To start the drill, depress the trigger switch.
Use the forward/
reverse control (3) to select the direction of rotation, then
squeeze the trigger switch (1). 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. The
switch is equipped with a brake, the chuck will stop as soon a trigger
switch is fully released.
To stop the drill, release the trigger switch.
OPERATING INSTRUCTIONS
Forward/reverse control
The forward/reverse control (3) allows you to change the direction of
the tool while the variable speed trigger is not depressed.
To select the forward rotation depress the control (3) toward the left
side of the tool. To select reverse depress the control (3) to the right
side of the tool.
Drilling uses the forward mode.
The reverse mode is intended for the removal of screws or
removal of drill bits from wall.
The centre position of the control button locks the tool in the
off position.
Variable speed
The variable speed feature is particularly useful when driving
screws.
It also enables you to select the best speed for a particular
application. The further you squeeze the trigger, the faster the tool
will operate.
Use lower speeds for starting holes without a centre punch, drilling
metals or plastic, driving screws and drilling ceramics, or in any
application requiring high torque. Higher speeds are better for drilling
in wood, wood compositions and for using abrasive and polishing
accessories. For maximum tool life, use variable speed only for
starting holes or fasteners.
NOTE: It is best to use the variable speed feature for a short
time only. Do not continuously operate the drill in variable
speed mode, this may damage the switch.
Drilling positions
This symbol indicates the DRILL POSITION. Use this mode
for high speed drilling, screwdriving (wood, aluminium and
steel) and the clutch will be locked.
Torque adjustment / selection collar (4)
By rotating the torque adjustment collar behind the chuck, it is
possible to adjust the torque to each of fifteen settings.
The range of fifteen settings allows better control when using the
drill as a screwdriver as it prevents over-tightening of the screws.
The numbers circling the collar are used to indicate the level of
torque. The higher number on the collar, the higher torque and
the larger the fastener which can be driven. To select any of the
numbers, rotate the collar (4) until the desired number 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 application.
To select the first gear (low speed, high torque setting), turn the tool
off and wait until it stops. Push the gear selector (5) back, away from
the chuck, so the number 1 is displayed.
To select the second gear (medium speed, medium torque setting),
turn the tool off and wait till it stops. Slide the gear selector forward
towards the chuck, so the number 2 is displayed.
NOTE: Do not change gears when the tool is running.
