4.12 Carbon brushes
This machine is equipped with carbon brushes with two protection features. The purpose of both
features is to schedule timely service and avoid additional costs by unexpected downtime or
unnecessary part replacement.
Carbon brush wear indicator
On top of the motor housing you will find an integrated LED light. Under normal circumstances this
light is off. The LED light will start burning red when the carbon brushes are worn to a level where it
is advised to replace them.
Actual remaining operating time depends on the use of the machine, but can be at least twelve
operating hours. This makes it possible to schedule service of the machine and avoid unexpected
downtime.
Automatic shut-off
As additional protection, when the carbon brushes are actually worn to a level where replacement is
needed, the motor will shut off automatically. This prevents the armature from being damaged.
During automatic shut-off, the carbon brush wear indicator is not lit.
For replacement of carbon brushes, see chapter 6. Maintenance.
4.13 Tool lubrication
In horizontal applications
In order to use the lubrication system, the tank must be filled with a cutting lubricant.
1.
Make sure the flow regulator is closed;
2.
Unscrew the cap;
3.
Fill the container with cutting lubricant;
4.
Screw the cap back on.
•
Adjust the fluid flow as required using the flow regulator;
•
Add more cutting lubricant when the shavings (metal chips) become blue.
Vertical and overhead applications
Dip the cutter in cutting paste or apply an appropriate spray.
WARNING:
Do not use the lubrication system in vertical or overhead drilling applications.
Instead use Euroboor cutting paste.
Make sure to use only suitable cutting lubricants. Euroboor offers a wide range of cutting lubricants
for all tool and material combinations. Proper lubrication will help you create better and faster
results, and extend the lifetime of your tools.
