WORKING HINTS FOR
YOUR TOOL
"
1. Reduce the pressure on the drill bit when it
is about to break through. This will prevent
the drill from jamming.
"
2. When drilling a large hole, first drill a pilot
hole using a smaller drill bit.
3. Always apply pressure to your drill bit in a
straight line, and if possible at right angles
to the workpiece.
4. Never change the operating mode whilst
the drill is running.
5. Do not apply excessive pressure to the tool
when chiseling. Expressive force does not
speed up the work.
