Originally designed for cutting and forming metal rivets, the Chicago Pneumatic buster is now used for concrete demolition and has become one of the starts of the CP range.
It has a low frequency blow with hitting power equivalent to paving breaker twice its weight. The new CPS includes a stepped piston and step cylinder to prevent accidental ejection of the piston.

The wear indicating groove on the lower sleeve indicates that the bumper is completely worn out and needs to be replaced.
When the bumper is 75% worn out, the bleeding ports are opened due to the outward movement of the upper and lower sleeves, this causes the piston to stop in its lower position and the air to exhaust above the retainer
Continuing to use the buster when the automatic stop function has triggered may cause damage to the sleeves and possibly the cylinder.
