Many tampers on the market are designed for sand ramming only and therefore lack the full power necessary for contracting operations.
CP 0003 is well equipped to handle light to medium contracting applications while CP 0004 is designed for heavier contracting jobs.
They are both light-weight, well balanced and easy to use first class compaction tools. The butt is secured to the lower end of the piston rod. A valve in the back head assembly controls the reciprocating movement of the piston.
The hand valve (trigger) controls the air flow.
