Operation Principle

Vibrating for ground compacting is accomplished occurred by a vibrator (A) that is installed on the
bottom plate (B) for tamping. There are two shafts in the vibrator for forward and reverse. One shaft
has two centrifugal vibrators. One of these two shafts receives hydraulic force and changes the angle
of the centrifugal vibrator. It makes the compactor move forward and reverse,
The air-cooled 4-stroke engine engine (C) is attached to the engine plate which interacts with the vi-
brator. Torque is delivered through the V - belt (E) that connects the Pulley (D) and the centrifugal
clutch that is attached to the engine.
When the engine operates at low speed, the centrifugal clutch cuts off power to the vibrator. The
speed of the engine is changes by the throttle control lever on the left-side of the handle (A14 in the
parts list).
Four shock absorbers (F) are between the engine plate (A24) and the vibrator plate (A01). This de-
creases the system vibration delivered with the engine plate.
