Though compact and lightweight, this rammer creates a strong impact and you may expect a large tamping effect on the
ground.
It will compact nearly all types of soil, except soft soil that contains too much moisture.
Use this rammer to tamp the ground for creating roads, embankments, and to prepare the surface to support buildings. It
can also be used when burying gas or water lines, and electric cables.
Do not use this machine on ground that is harder than the machine can handle, or for driving pilings or tamping rock beds.
Furthermore, use of the machine on sloping ground such as the side of an embankment, may be make the machine
unstable and can cause an accident. It can also result in premature machine wear due to uneven loads on the machine.
Use the machine with confidence for tamping earth and sand, soil, sand, gravel, and asphalt. Do not use the machine for
other type of jobs.
The upper section of the machine functions as a weight and consists of an engine section guide, a gear reducer section,
and reciprocating section. It also accommodates the handle and the fuel tank sections, which are connected by rubber
dampers.
The lower section of the machine which hits the ground, consists of a spring case to engage sliding motion, a sloping section
to allow the machine to tilt toward the front, a dust sleeve to cover sliding section,foot to hitting the ground.
Power is provided by an air-cooled, 4-cycle, single-cylinder gasoline engine. The output end of the engine crankshaft is
equipped with a centrifugal clutch.
As the engine speed increases, the centrifugal clutch expands and a pinion gear that is a part of the clutch drum engages
a gear in the crank shaft on the main frame. The engine speed is decreased in order to produce the required force for tamp-
ing.
The rotating motion of the main frame crankshaft is converted to a reciprocating motion through a connecting rod. This
reciprocating motion causes the foot to go up and down through a strong coil spring. The weight of the main body and the
strong force from the engine compress the spring and the foot moves up and down, striking the ground forcefully.
