g.1

4.1. preparing drill for use.

4.1.1. ensure the drill is switched off and unplugged from the power supply.

4.1.2. fitting the side handle. (fig.1.8) fit side handle grip by placing the handle assembly over the chuck and onto the machine neck.
secure by rotating the handle clockwise until it is tight and the handle can no longer be moved. to ensure a good grip in all

circumstances, the angle of the handle may be changed by rotating the handle grip anticlockwise until the handle assembly is loose.

Rotate the handle to the desired angle and re-tighten.

4.1.3. fitting the depth gauge. (fig.1.7) to fit the depth gauge loosen the side handle and pass the gauge through the handle clamp to the

required depth. rotate the handle to the required angle. As the handle is tightened the depth gauge will also be gripped firmly.

4.2. drill controls

4.2.1. ON/OFF Variable speed trigger. The drill has a variable speed control On/Off trigger (fig.1.2) speed increases as the trigger is

depressed. Adjacent to the trigger is a button that can be used to lock the trigger in the ‘ON’ position for continuous drilling.

4.2.2. Trigger lock. (fig.1.1) To lock ‘ON’, depress the trigger, push in and hold the button then release the trigger. Release the lock-on button

and the drill will continue running.

4.2.3. to release the lock, depress the trigger and the lock releases.

4.2.4. Power failure. If you have the lock-on feature engaged during use and the drill becomes disconnected from the power supply,

make sure that the lock is released, before reconnecting to the power supply.

 WarNiNG! Before connecting the drill to a power supply, ensure it is not in the lock-on position as this may result in damage and

personal injury. depress the trigger to ensure release. dO NOt use the lock-on facility for jobs where the drill may need to be stopped
suddenly. ,

4.2.5. Maximum speed setting control. The variable speed trigger has a small rotating knob incorporated into it (figs.1.3) which can

be used to control the maximum speed of the drill. When the knob is set to the maximum or + setting the trigger can be fully
depressed allowing the drill to turn at its maximum speed. As the knob is turned towards the minimum or - setting, the movement of
the trigger is restricted so that the drill will turn at a lower pre-set speed when the trigger is depressed. This facility is useful when

working with materials that should be drilled at a constant, lower speed.

4.2.6. the required speed will depend on the material and task in hand. the following may be used as a general guide.

a) low speeds are recommended for hard materials, i.e. stone, ceramic, concrete, high tensile steel, and tasks such as starting
holes without centre punch, driving screws, mixing paint etc.

b) medium speeds are suitable for plastics and laminates.

sD750 | Issue 1 15/09/16

c) High speeds recommended for soft materials such as wood, aluminium, copper, bronze and brass.

 WarNiNG!: dO NOt run the drill at low to medium speeds for extended periods of time as this may cause drill to overheat.

to cool drill, run it without a load, at full speed, for a few seconds.

4.2.7. direction of rotation. select either forward or reverse rotation using the lever mounted directly above the trigger (figs.1.4).

Select reverse by moving the lever towards the ‘L’ symbol and forward by moving the lever adjacent to the ’R’ symbol and the trigger

lock button.

 WarNiNG! dO NOt attempt to change direction of rotation whilst the drill is still running.

4.2.8. Selection of hammer action / drilling. When using a masonry drill bit, the hammer action can be used to assist penetration into

concrete, stone and masonry. The hammer action selector is a large sliding ‘switch’ situated on top of the drill.

to select hammer action slide the selector to the left so that it is adjacent to the hammer symbol moulded on the side of the case.

to disable the hammer action slide the switch in the other direction to be adjacent to the drill symbol moulded on the casing.

4.3. drill or tool Bit fitting.
 WarNiNG! unplug from the mains power supply before placing bit into chuck.

Adjust the chuck jaws to a point where the opening is slightly larger than the drill/tool bit to be used. Also raise the front of the drill

slightly to stop the bit from falling out of the chuck jaws. Insert the drill/tool bit into the chuck. Place the chuck key in one of the chuck

holes and tighten the chuck fully by turning the chuck key clockwise.

4.4. depth Stop Gauge.

ensure the work piece has a flat surface and is wide enough for the gauge to butt up against it when the required depth has been reached.

Measure back from the tip of the drill bit to the point at which the drill must stop. Release clamp/handle and extend the depth gauge to the
point at which you wish to stop drill penetrating further and righten the handle/clamp. Once the drill has reached the correct depth, the

gauge will butt up against the work piece and stop further inward progress.

4.5. Standard drilling instructions.
 WarNiNG! ensure you wear approved safety goggles and any other safety item required for the job. remove the chuck

key before using the drill, and ensure the trigger button lock is not locked in position which would result in accidental
starting of the drill.

ensure drill is unplugged from the mains power supply.

4.5.1. if the material to be drilled is free standing it should be secured in a vice or with clamps to keep it from turning as the drill bit

rotates.

4.5.2. When drilling metals, use a light oil on the drill bit to keep it from overheating. Oil will prolong life of the drill bit and improve the

drilling action.

4.5.3. for hard smooth surfaces use a centre punch to mark desired hole location. this will prevent bit from slipping as drilling is started.

4.5.4. A pilot hole may be necessary to assist the nal drill size through the work piece. Lock a pilot drill (smaller size drill than the nished

hole size) into the chuck. Follow steps 4.5.5 to 4.5.7. below and drill a pilot hole in the middle of the centre punch mark where nal
hole is to be drilled. Insert the nal sized bit. Hold drill rmly and place the bit at the entrance of the pilot hole and depress the

trigger.

4.5.5. Plug drill into mains power supply.

4.5.6. Hold tool rmly and place the drill bit tip to the point to be drilled.

4.5.7. depress the trigger to start drill. move the drill bit into the work piece, applying only enough pressure to keep the bit cutting.

8 dO NOt force or apply side pressure, which will elongate the hole.

 WarNiNG! Be prepared for drill binding or break through. When these situations occur the drill has a tendency to grab and

kick in the opposite direction and could cause loss of control. if you are not prepared, this loss of control could result in damage

and/or personal injury.

4.5.8. if the drill bit jams in the work piece or if the drill stalls, release the trigger switch immediately. remove the drill bit from the

work piece and determine the reason for jamming, before recommencing drilling.

4.5.9. for continuous operation, depress the trigger lock.

4.5.10. the depth gauge may be used to pre-determine the depth of hole.

4.5.11. After working for a lengthy period of time at low speed setting, run drill for a few seconds with no load, at high speed.
 WarNiNG! drill bits become very hot during use. Allow to cool or hold with a cloth for removal.

4.5.12. When work is complete, unplug from the mains power supply, remove the drill bit / tool bit from the chuck, clean drill, clean and if

necessary sharpen the tool bit, and store drill in a safe, dry childproof location. ,

5. maiNteNaNce

5.1. changing the drill chuck.

To remove the drill chuck, open the chuck fully. Locate the internal screw head and undo by turning the screw CLOCKWISE (left handed
thread). stop the chuck from moving by securing the nut at the base of the chuck with a spanner. to replace the chuck reverse the
above procedure.

5.2. cleaning the drill.

Keep the drill ventilation slots clean and free from obstructions. if available, blow compressed air into the vents to clear any internal
dust (safety goggles must be worn when undertaking this process). Keep the outer case of the drill clean and free from grease

8 dO NOt wash with water, use solvents or abrasives.
