If the engine doesn’t turn, the main switch is moved to ON, then pull starter recoil; low oil light may blink for a few seconds, and engine oil is inadequate lubricant retry.

Overload ALARM (RED)

TVs AC output indication (Green) the red overload alarm light stays on, and the cromtech 2400w inverter generator will not stop. The overload alarm light blinks when the full power of proximity to electrical devices rating hp. When it detects a power surge to all linked devices, the circuit breaker protects the generator by starting and stopping it.

In case of overload, proceed with caution:

1. Disconnect all gadgets activate the reset button

2. Minimize the total wattage of electric gadgets.

3. Verify intake and control for obstructions. Clear a blockage.

 4. After that, start the engine.

STORAGE of your Cromtech 2400w Inverter Generator

Follow these precautions to protect your machine against deterioration when placed away for storage for an extended period.


  1. Remove the cap from the petrol tank. Using a hand syphon, drain the petrol from the fuel tank into an appropriate petrol container. Hand syphons are readily available on the market. After that, secure the fuel tank cap.
  2. Remove the carburettor drain cover, remove the drain screw on the carburettor float chamber, and drain the fuel into a petrol container that the manufacturer has approved.
  3. Install the carburettor drain cover after tightening the carburettor drain screw.
  4. Allow it to run, start the engine, and come to a complete halt (As it has used all remaining fuel in the carburettor).

Cromtech 2400w Inverter GeneratorPRESERVE THE ENGINE’S PERFORMANCE

Please follow the instructions below to protect the engine, the interior of the cylinder, the piston rings, and other components:

  1. Remove the spark plug and fill the spark plug hole with around 5ml SAE10W30 or 20W40 engine oil. Replace the spark plug and repeat the process. Make numerous pulls on the recoil starter, so that engine oil achieves distribution throughout the cylinder wall, piston rings, and other components.
  2. When you sense compression, stop pulling the recoil starter (this prevents rust in the cylinder and valves).


  1. Thoroughly clean the exterior of the generator. 
  2. Only moist towels should be used ( with a bit of detergent) – over wetting should be avoided.
  3. Cover the generator with a clean cloth and store it in a dry, well-ventilated area away from children and pets.
  4. When being stored, transported, and operated. Generators should be upright to help avoid leaks.


When transferring the generator, remember to: 

  1. Overfilling the tanks should be avoided (there should be no fuel in the filler neck); and 
  2. Do not overload the trailer.
  3. Never operate a generator when it is attached to a vehicle. It is necessary to run the generator in a well-ventilated location.
  4. Avoid installing the generator on a vehicle in areas that may expose it to direct sunlight. After being left in an enclosed vehicle for an extended period, the high temperatures inside the vehicle could cause the gasoline to evaporate, resulting in a possible explosion if the generator is not moved.
  5. Using a generator while driving on a rough road for a long time is not a good idea. If you have to transport the generator on a bumpy road, drain the fuel from the generator before you start the vehicle.
  6. Make sure that the Vent knob is in the OFF position.
