Never hold the workpiece in place with your
hand!
When drilling, the workpiece should be able to travel
on the drill table (4) for self-centering purposes.
Ensure that the workpiece cannot rotate. This is best
achieved by placing the workpiece/machine vice on a
sturdy block.
Caution! Sheet metal parts must be clamped in to
prevent them from being torn up. Properly set the
height and angle of the drill table for each workpiece.
There must be enough distance between the upper
edge of the workpiece and the tip of the drill bit.
7.9. Drilling wood
Please note that sawdust must be properly
evacuated when working with wood, as it can pose a
health hazard. Ensure that you wear a suitable dust
mask when performing work that generates dust.
7.10. Working speeds
Ensure that you drill at the proper speed. Drill speed
is dependent on the diameter of the drill bit and the
material in question.
The table below acts as a guide for selecting the
proper speed for various materials.
Note: The drill speeds specified are merely
suggested values.

7.11. Countersinking and center-drilling
With this table drill, you can also countersink and
center-drill. Please observe that countersinking
should be performed at the lowest speed, while a
high speed is required for center-drilling.
8.0. Care and maintenance
The table drill is to a large extent maintenance-free.
Keep the device clean.
Pull out the mains plug before doing any cleaning
and maintenance work on the machine.
Do not use any harsh, abrasive cleaning solvents.
Ensure that no liquid seeps into the device.
Regrease all bare parts when the work is finished.
The drill pillar, blank parts of the column, and the drill
table especially should be regreased at regular
intervals. Use a standard, acid-free lubricating
grease to do this.
Caution: Do not use your household refuse bin as a
receptacle for oil and grease-soaked cleaning rags or
grease and oil sludge. Dispose of these toxic
materials in an environmentally-friendly fashion.
Regularly check and clean the ventilation holes.
Store the device in a dry room. Should the device
become damaged, do not try to repair it yourself;
leave this work to the hands of a qualified electrical
technician.
