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.
