DRILL/DRIVER OPERATION (cont.)
General Hints for Drilling in all Materials
•
Always use sharp drill bits.
•
Mark the place where you would like the hole to be drilled.
•
Commence with a slow speed to start the hole (see section "Variable Speed
Switch" for directions on how to do this).
•
Reduce pressure on the drill when the drill bit is about to break through the material.
Metal Drilling
•
Support thin material with a piece of scrap wood.
•
Use a centre punch to mark the position of the hole.
•
If drilling a large hole, use a small size drill bit first to establish a pilot hole then
use the required large size drill bit.
•
Use only HSS (high speed steel) drill bits or those recommended for metal use.
•
When drilling into iron or steel, use a cooling lubricant such as thin oil. With
aluminium, use turpentine or paraffin. With brass, copper and cast iron, use no
lubricant but withdraw the drill regularly to assist cooling.
Wood Drilling
•
Mark the place where you want to drill with a punch or a nail.
•
To avoid splintering on breakthrough, either clamp a piece of scrap wood to the
back of your workpiece or continue the hole from the back of the wood when the
drill bit first breaks through.
Battery Charge Indicator
•
The drill is equipped with a battery charge indicator (7) to show the state of the
battery charge.
•
Press the Variable speed switch (9).
•
Look to see which LED lights (see Fig. 9).
•
A red LED indicates that the battery (5) requires
immediate charging.
•
An orange LED indicates that the battery (5) has only a
low charge and requires charging soon.
•
A green LED indicates that the battery (5) is fully
charged and ready to use.
LED Lights
•
The drill has 1 built-in LED light (8). The LED is located
above the battery charge indicator (7) (see Fig. 10).
•
The LED light (8) illuminates automatically when you
depress the variable speed switch (9).
•
The LED light is used to illuminate dark areas in tight
corners to assist with drilling and screw driving. This
helps you see the work piece to achieve more
accurate results.
