TROUBLE SHOOTING
Fault Symptom Possible Cause Troubleshooting
Out of service at switch-on Shortcircuit in electric machine
winding
Replace stator and rotor by repairer
Disconnection between plug and
power socket
Insert plug in power socket
No voltage in power socket Check and repair power supply
Wearout of carbon brush Replace carbon brush
Loose switching contact Check and replace switch by repairer
Loose contact between carbon
brush and cummutator
Check connection between carbon
brush and commutator by repairer
Excessive sparkling during running Underpressure in carbon brush
spring
Replace carbon brush subassembly
by reparier
Excessive wearout of carbon brush Replace carbon brush subassembly
by reparier
Overvoltage in supply power Regulate supply voltage
Disconnection between carbon
brush and commutator
Replace carbon brush
Ring fire caused by shortcircuit in
rotor winding
Check or replace rotor by repairer
Ring fire caused by shortcircuit in
commutator segment
Check or replace rotor by repairer
Running speed drop Supply voltage decline Check power supply
Damage in mechanical part Replace mechanical part by repairer
Low-speed at starting Regulate speed governor at high-
speed
Partial shortcircuit in rotor Check or replace rotor by repairer
Excessive noise Damage in winding or breakdown
in motor
Check electric motor by repairer
Excessive axial thrust or overload
percussion drilling
Decrease thrust force
Drilling bit stuck during drilling
metal part
Stop drilling
Stuck at transmission gear Check mechanical part
Insufficient or unclean lubricating
oil in gear box
Replenish or replace lubricating oil
Bearing wearout or stator/rotor
deviating friction during running
Regulate bearing
Electric motor failed to reach full
power
Electrocircuit overload due to
lighting device, public utility or
other electric appliances
No use of public utility or other
electric appliances on machine-
connected electrocircuit
Overheating in percussion drill Overload in electric motor or
insufficient cooling in electric
motor
Prevent electric motor from
overload running or dedust electric
motor to ensure best cooling effect
Insufficient/excessive-thick
lubricating oil or greasy bearing
Replenish/replace lubricating oil or
clean up bearing
B e a r i n g i n e x c e s s i v e t i g h t
positioning
Regulate bearing fastening clearance
or replace bearing
Rotor shaft gear tooth bending Calibrate or replace rotor shaft or
gear shaft
Drilling bit wearout Replace drilling bit
Overheating in reduction gearbox:
insufficient/greasy lubricating oil
or excessive tight gear engagement
or stuck by foreign body
Replenish/replace lubricating oil or
clean up gear
