Engine starts and runs smoothly, but no power output at sockets
Loss of residual field magnetism, worn carbon brushes, or failed AVR module.
Rotor/stator resistance testing, excitation circuit re-flashing, and brush/AVR replacement.
Preventative servicing, load testing, AVR voltage regulation, and mechanical overhauls for petrol and diesel generators
Generators are critical safeguards during power outages or on remote job sites without grid connection. If an aggregate fails to start or outputs erratic voltage, equipment damage and costly work stoppages follow.
AVEMAK delivers qualified mechanical overhauls, electrical frequency and voltage testing, and regular maintenance for portable and stationary generators. We inspect AVR regulators, service fuel systems, and test machines under simulated electrical load.

Verifying stable 50 Hz and precise 230V / 400V outputs.
Removing storage varnish and replacing fuel filters on petrol and diesel units.
Sustained load runs to diagnose power drop under heavy draw.
Routine health checks for standby and construction power units.
Independent engineering expertise for compact construction, forestry, and municipal plant
Compact units for sensitive electronics; inverter module and throttle servo diagnostics.
Job site power units; carburetor service, tank flushing, shock mounts, and capacitors.
Continuous heavy-duty sets; fuel bleeding, glow plugs, injector spray testing, and alternators.
Servicing integrated power plants for night-time civil construction works.
Typical mechanical, electrical, and hydraulic issues diagnosed and resolved at our Berlin workshop
Loss of residual field magnetism, worn carbon brushes, or failed AVR module.
Rotor/stator resistance testing, excitation circuit re-flashing, and brush/AVR replacement.
Governor linkage out of adjustment, fuel restriction, or engine power shortfall.
Speed governor recalibration, fuel filter renewal, and carburetor/injector cleaning.
Gummed jets from aged fuel or water condensation in the fuel tank.
Tank drain, ultrasonic carburetor cleaning, spark plug renewal, and fresh fuel charge.
Preventative care to prevent catastrophic failure and reduce expensive downtime
Manufacturer-independent servicing for commercial petrol and diesel units:
Notice: AVEMAK operates as an independent service specialist. All mentioned brands are used purely to indicate technical compatibility.
Transparent stages from initial booking to certified load testing
Record unit rating (kVA), fuel type, and reported failure symptom.
Separate testing of internal combustion engine and alternator stages.
Precision replacement of electrical or mechanical components.
Proof testing under resistive load to verify stability.
Key answers regarding diagnostics, replacement parts, and logistics
Modern fuels degrade within months, absorbing humidity and gumming carburetor jets. For standby generators, we recommend fuel stabilizers or alkylate fuels.
Only if the unit features inverter technology or high-precision AVR regulation. Standard generators produce voltage spikes. We can verify your unit's stability.
At least once annually with a full load test and oil change to ensure immediate start-up during emergencies.
