Ballast Hand Tamper


Petrol Tie Tamper BH23

Description of function

The engine, which is flanged to the crankcase and is held in place by 3 screws, drives the percussion system over a gear transmission and a connecting rod.  The engine torque is transmitted by means of a centrifugal clutch.

The centrifugal clutch interrupts the flow of power to the percussion system at low engine speeds, thus allowing for a perfect idling of the engine.

The engine can be switched off with the stop button or the fuel tap.

The drive engine works according to the 2-stroke principle, and is started mechanically by means of a recoil starter.  The engine is air-cooled and the air necessary for combustion is directed through the air filter.
