3. OPERATING INSTRUCTIONS
3.1.
PREPARING DRILL FOR USE.
3.1.1. Ensure the drill is switched off and unplugged from the mains power supply.
3.1.2. Fit supplementary handle grip (fig 1 item 8) by placing over chuck
head and onto the drill grip collar. Secure with the retention screw (9).
This grip is used to improve control over the drill. The handle may be
angled, affording a more stable grip for various drilling tasks.
The handle grip further allows the attachment of a depth gauge. To fit the
gauge loosen screw 9 and slide the gauge through the corresponding hole.
Re-tighten screw 9.
3.2.
DRILL SPEED.
The required speed (or rpm). will depend on the material and task, and can be determined by testing. The following may be used as a guide.
3.2.1. Low speeds are recommended for hard materials such as stone, ceramic, glass, concrete and high tensile steel and tasks such
as starting holes without centre punch, driving screws, mixing paint etc.
3.2.2. Medium speeds are suitable for plastics and laminates.
3.2.3. High speeds recommended for soft materials such as wood, aluminium, copper, bronze and brass.
3.2.4. Your drill has a variable speed control on/off trigger (fig 2 item 1) which increases the speed the more
the trigger is depressed.
3.2.5. The trigger has a speed control selector Incorporated (fig 2 item 4) designed to allow control
and adjustment of speed and torque limits. The speed and torque of your drill can be increased or decreased
by rotating the variable speed control selector in the direction of the arrows on the switch, (-) decreases speed
and torque and (+) will increase speed and torque.
3.2.6. To pre-set and lock the trigger at a given speed, set the selector (4) to the required speed, depress the trigger (1) fully and
press the trigger lock-on button (5), also see 3.5. Release the trigger and the speed will drop to that pre-set. Note: if the variable
speed control selector is fully turned in the low speed (-) direction your drill may not operate on some tasks as the torque will be very
low. To achieve such a low speed performance you may have to use the variable trigger (1) only. Familurise yourself by practicing variable
speed adjustments. If you do not wish to use variable speed control selector (4) turn the selector to full (+) speed, and control
drill speeds by the trigger only.
s CAUTION: DO NOT run your drill at low to medium speeds for extended periods of time as this may cause drill to overheat. If this occurs, cool
your drill buy running it without a load at full speed for approximately 3 minutes.
3.3.
DEPTH STOP GAUGE.
If you require to drill a precise depth you can set the depth gauge (fig 1 item 7). Ensure the workpiece has a flat
surface and is wide enough for the gauge to butt up against once the required depth has been reached.
Measure back from the tip of the drill bit to the point at which the drill must stop. Slacken the retaining screw
(fig1 item 9) and extend the depth gauge to the point at which you wish to stop the drill penetrating further (fig 3)
and tighten (9). Once drill has reach correct depth the gauge will butt up against the workpiece and stop
further inward progress.
3.4.
DRILL OR TOOL BIT FITTING.
p WARNING! Unplug from the mains power supply before placing bit into chuck.
Open or close the chuck jaws to a point where the opening is slightly larger than the drill or tool bit (fig 4 A) to be used.
Also raise the front of the drill slightly to prevent bit from falling out of the chuck jaws. Insert the drill bit into the chuck
as far as it will go. Place the chuck key in one of the chuck holes and tighten the chuck securely.
p WARNING! Ensure you remove the chuck key before starting the drill.
3.5.
TRIGGER LOCK.
3.5.1. Your drill is equipped with a lock-on button (fig 1 item 5) which is convenient when continuous drilling for extended
periods is required. To lock-on, depress the trigger, push in and hold the lock-on button then release trigger. Release the lock-on
button and the drill will continue running accordingly.
3.5.2. To release the lock depress the trigger and release it.
3.5.3. Power failure. If you have the lock-on feature engaged during use and your drill becomes disconnected from the power supply,
disengage the lock-on feature immediately.
p WARNING! Before connecting your drill to power supply, ensure it is not in the lock-on position as this may result in damage
and/or personal injury. Depress the trigger to ensure release.
DO NOT use the lock-on facility for jobs where your drill may need to be stopped suddenly.
3.6.
FORWARD & REVERSE SWITCHING.
The chuck rotation direction is controlled by the direction lever (fig 2 item 2). With drill held in normal operation position, the direction lever must
be positioned to the right of the on/off trigger (see symbol on drill body at side of lever marked FWD (forward) this is the correct direction for
normal drilling tasks. To reverse chuck rotation direction turn the lever to the left REV (reverse) position. The reverse direction is used for
unscrewing, for insertion of left hand threaded screws, and in some cases for the release of jammed drills.
p WARNING! Do not change direction whilst the drill is running. Release trigger and allow drill to stop before changing direction.
