Insert the clamping shaft of the abrasive wheel all the way
into the collet chuck.
Tighten down tensioning nut.
The abrasive wheels must run true. Do not use
abrasive wheels which have gotten out of round.
Trial run!
Check grinding tools before use. The grinding tool must
be correctly mounted and must rotate freely. Perform a
trial run a minimum over a period of 30 seconds without
load. Do not used grinding tools which are damaged,
which do not run true or which vibrate!

To achieve an optimum grinding result, move grinding
wheel uniformly back and forth with light pressure. The
electronic constant control maintains the speed nearly
constant during idling and work under load and assures
a uniform result. Excessive pressure lessens the working
capability of the machine, as well as the life of the grind-
ing wheel. The machine is equipped with an electronic
control and integrated overload protection. If the machine
is overloaded, the speed will drop drastically. Immediately
take the load off the machine and allow to run for a short
time without load.

all times. When machining metal under extreme working
conditions conductive dust can deposit inside the ma-
chine, which can deteriorate the insulation of the tool. In
such cases the use of a stationary vacuuming system,
frequent blowing out of the ventilation slots and protection
with a fault-current protection switch are advisable.

hAnging the cArBon Brushes
The Automatic-Stop feature protects the machine
from defects due to excessively consumed car-
bon brushes. The machine is equipped with two
carbon brushes, i.e. one is installed in each handle half.
The carbon brushes must be changed as follows:
Unscrew four screws and remove the handle halves.
Lift spring with screwdriver and remove brush. Install new
brushes. Clean carbon brush holders, making absolutely
sure not to change the carbon brush arrangement of the
carbon brush assembly. Fit handle halves and fasten with
four screws.
Repeat this change on the opposite side, making
absolutely sure to avoid both handle halves from
being opened at the same time.
