Working Instructions - PFERD UGER 15/60 SI 120 V Originalbetriebsanleitung

Grinding tool:
Use only grinding tools whose admissible maximum speed is equal
to or higher than the no-load speed of the machine.
Dust Warning:
Use of the tools in this instructions may create dust and other par-
ticles. To avoid any risk of adverse health effects, the operator must
use appropriate protective measures, including a respirator, during
and after tool operation. Refer to our Material Safety Data Sheet
(MSDS) for further information regarding the product to be used.
Furthermore, additional health hazards may result from dust in the
surrounding environment and from dust generated from the work
piece material. PROTECTIVE MEASURES FOR THE OPERATOR MUST
ADDRESS DUST AND OTHER PARTICULATES ARISING FROM ALL
SOURCES. Always use our products in a well-ventilated workspace.
Changing/fitting the grinding tool.
Use only clean tools!
1) Hold working spindle against turning at wrench flats with fork
spanner SW 22 mm.
2) Release the clamping nut with fork spanner SW 22 mm.
Insert the clamping shaft of the abrasive wheel all the way into the
collet chuck.
1) 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!

Working instructions:

• T o achieve an optimum grinding result, move grinding wheel
uniformly back and forth with light pressure.
• T he electronic constant control maintains the speed nearly constant
during idling and work under load and assures a uniform result.
• E xcessive pressure lessens the working capability of the machine,
as well as the life of the grinding wheel.
• T he machine is equipped with an electronic control and integrated
overload protection.
• I f the machine is overloaded, the speed will drop drastically. Im-
mediately take the load of the machine and allow to run for a
short time without load.
Preventive maintenance:
• T o work effectively and surely keep the machine and the ventila-
tion slots clean at all times.
• W hen working on metal under extreme working conditions
conductive dust deposits can occur inside the machine thereby
impairing the protective insulation of the tool. In such cases the
use of a stationary vacuuming system, frequent blowing out of
the ventilation slots and protection by a fault current protection
switch are advisable.
1)
Changing the carbon brushes:
The Automatic-Stop feature protects the machine from defects due
to excessively consumed carbon 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:
2)
Unscrew four screws and remove the handle halves.
1)
1) Lift spring with screwdriver and remove brush. Install new brushes.
Clean carbon brush holders, making absolutely sure not to change
the arrangement of the elements of the carbon brush assembly.
Fit handle halves and fasten with four screws.
Repeat this change on the opposite side, making absolutely sure
to avold both handle halves from being opened at the same time.
