A white cap is used to protect the machine from splashes of concrete when poured on the worksite. This alleviates the burden of after-project maintenance.

Exen lightweight generators are fully-enclosed, external fan types that protect against the ingress of foreign matter. They are equipped externally with a wind-inducing cover, and a powerful fan is used to realize an even more efficient cooling system.

The frame structures of various models are stackable and easy to manage for different models, and particularly helpful in storage in cramped warehouses.

The models are protected from burns due to vibrator overload and burns on the generator side by installing a no-fuse breaker (NFB) inside the wall outlet box.

The engine incorporates an oil sensor mechanism (a seizure-prevention automatic engine stopper). If engine oil runs out during operation, the engine stops automatically. *If oil is available to a specified level but the machine is tilted, then the oil sensor mechanism may be activated to stop the engine.
