2.1 Application
Rammers are designed to compact loose soils and gravel to prevent settling and
to provide a firm, solid base for the placement of footings, concrete slabs,
foundations, gas piping works, water pipe works and cable backfill works, etc.
Please do not use in such as following cases. It may cause damage
because machine is likely to be unbalanced.
Pile foundation
Hard soil excessively compacted over normal condition
Steep bank slope
The maximum compaction depth of the soil depends on several factors relating to the
nature of the soil, such as water content, grain-size distribution, etc. It is therefore not
possible to specify a given layer depth.
2.2 Structure
The upper part is made up of Power source, Clutch, Connecting Rod and
Operating Handle, Fuel Tank that connected via Shock Absorbing Rubber to body.
Bottom end is made up of Spring Cylinder (Sliding part), Foot Plate that ramps
body, Foot and Bellows that covers sliding part.
2.3 Before Starting
Check the oil level through a window at rear end of the foot. Replenish oil if oil is not
visible at the window. For lubrication, use automobile engine oil of 10W-30 SE, SF
or better grade. Capacity is 830cc. Low lubrication oil level may result in engine
seizure due to consumption during operation.
Check every bolt, nut or screwed area for tightness.
Loosened due to vibration
may result in unexpectedly serious trouble. Be sure to tighten any screwed
area.
Remove dirt and dust. Particularly clean the vicinity of recoil starter and foot.
Place rammer on loose soil or gravel. DO NOT start rammer on hard surfaces such
as asphalt or concrete.
