10.3 Metal drilling
For maximum performance, use high speed steel bits for metal or steel drilling. Turn the
torque adjustment ring on the drill to desired torque setting. Begin drilling at a very low speed
to prevent the bit from slipping off the starting point. Maintain a speed and pressure which
allows cutting without overheating the bit.
Applying too much pressure will:
▪ Overheat the drill
▪ Wear the bearings
▪ Bend or burn bits
▪ Produce off-center or irregular shaped holes
When drilling large holes in metal, it is recommended that you drill with a small bit at first, then
finish with a large bit. Also, lubricate the bit with oil to improve drilling action and increase bit
life.
11 CLEANING AND MAINTENANCE
11.1 Cleaning
▪ Keep the ventilation slots of the machine clean to prevent overheating of the engine.
▪ Regularly clean the machine housing with a soft cloth, preferably after each use.
▪ Keep the ventilation slots free from dust and dirt.
▪ If the dirt does not come off use a soft cloth moistened with soapy water.
▪ Never use solvents such as petrol, alcohol, ammonia water, etc. These solvents may
damage the plastic parts.
11.2 Maintenance
▪ Our machines have been designed to operate over a long period of time with a minimum
of maintenance. Continuous satisfactory operation depends upon proper machine care
and regular cleaning.
