Drilling
When drilling, the following points should be observed:
1
Always use sharp, good quality drill bits. The performance of your drill
depends on the quality of the bits used.
2
Reduce the pressure on the drill bit when it is about to break through.
This will prevent the drill from jamming.
3
If the drill bit does jam on breakthrough, release the trigger switch and
when the motor has come to a complete standstill, reverse the direction
of rotation and slowly operate the trigger switch.
4
If drilling a large hole, first drill a pilot hole using a smaller drill bit.
5
Always apply pressure to your drill bit in a straight line and, where
possible, at right angles to the workpiece.
6
When drilling holes or driving screws into walls, floors etc., always make
sure that there are no live electrical wires in the path of the bit.
7
When drilling in metal, the materials being drilled can become hot. To
reduce overheating use a suitable cooling lubricant. No cooling lubricant
is necessary when drilling cast iron or brass as they should be drilled
dry.
8
To prevent the drill bit from slipping when starting to drill a hole in metal,
use a center punch to make an indentation at the start point.
WARNING!
WHEN THE TRIGGER IS RELEASED, THE DRILL
WILL CONTINUE TO ROTATE FOR A SHORT TIME
