TROUBLESHOOTING
Danger due to electrical voltage! Manipulating the machine with the voltage
source connected upright can result in serious injury or death. Disconnect the
machine from the power source before you begin work to eliminate defects!
Fault
Motor does not start
Motor overheated
Engine stuck
Machine becomes slow
during operation
Machine vibrates
Wavy surface of the
workpiece
Scratches on the surface
of the workpiece
Spraying sparks or cracks
in the workpiece
Grinding wheel quickly
becomes blunt, grain falls
out
Grinding wheel "clogged",
workpiece has
combustion markings

Possible Cause
Low voltage
Open circuit in motor or loose
connections
Short-circuit in cable or plug
Motor overloaded
Short circuit in motor or loose
connections
Low voltage
Incorrect fuse or circuit breaker in
circuit
Motor overloaded
Pressure too high
Dirt on rotating parts
Unequal wear of the grinding
wheel
Machine not mounted on a solid
surface.
To hard grinding wheel or to high
feed speed
Contamination on the surface of
the pane
Workpiece is not sufficiently held
in place
Incorrect grinding wheel
Incorrect delivery
No or too little) Coolant required
Cutting depth too large
grinding wheel is too soft for the
material to be machined
Grinding wheel diameter too small
Poor post-treatment of the
grinding wheel
Defective grinding wheel bond
Grinding wheel is too hard
Coolant required.

WARNING
TROUBLESHOOTING
Correction
Check mains voltage
Check line connections on the
motor for loose or open
connections.
Check plug for damaged
insulation and short-circuited
wires.
Reduce motor load
Check motor connections for
loose or short-circuited
terminals or burnt-out
insulation.
Correct low voltage
Install the correct fuse or
circuit breaker.
Reduce motor load
Decrease pressure
Cleaning
Dressing the wheel
Check whether the machine
has been securely mounted
on a solid surface and/or use
a holder to hold the
workpiece securely in place.
Use softer grinding wheel or
reduce feed speed
Clean the surface of the
grinding wheel
Use a holder to hold the
workpiece securely in place.
Use softer grinding wheel or
grinding wheel with coarser
grain size
Reduce the infeed of the
workpiece into the grinding
wheel.
Add coolant system or add
coolant manually
Reduce the infeed of the
workpiece into the grinding
wheel.
Select a softer bond
Replace grinding wheel
Treating the surface of the
grinding wheel
Contact the manufacturer of
the grinding wheel.
Choose a softer bond
Add coolant system or add
coolant manually
