Wood drilling
▪
For maximum performance, use high speed steel bits for wood 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. Increase the speed as the drill bit bites
into the material. When drilling through holes, place a block of wood behind the workpiece
to prevent ragged or shintered edges on the back side of the hole.

Metal drilling
▪
For maximum performance, use high speed steel bits for metal or steel drilling. 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.

Screw driving
▪
Set the torque setting low enough to allow a safety margin. Start with a low torque setting
when first driving screws into a material. Then adjust the setting as the proper force
required is determined.
▪
The size of the screw in combination with the hardness of the material will determine the
torque setting.
▪
The torque starts at setting "1" (lowest torque) to setting "21" (highest torque).
10 CLEANING AND MAINTENANCE
10.1
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.
10.2
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.
