The APT M160A, Airgo-Line® Paving Breaker is a 60 lb class tool. The ergonomically designed handle helps reduce harmful vibration to the hands and arms of the operator. The versatile tool is based on the standard Model 160, the tool being easily converted to the standard handle or ergonomic handle or vise-versa. No power is lost from the standard tool but does increase efficiency and output due to the reduction in operator fatigue

Air Pressure

The recommended air requirement for the operation of APT tools is 90 psi (6.2 bar). Lower air pressure will decrease power, too high a pressure will increase unwanted stresses in the tool. For proper CFM ratings, please refer to the specification charts shown for each tool in this catalog.

Hose Size

APT recommends the use of at least 1⁄2” inside diameter or larger hoses to assure sufficient air flow to the tool. For portable compressor hose and longer lengths, 3⁄4 “ hose is recommended. Keep the overall length of the hose to a minimum to prevent pressure loss at the tool.

Connecting Hoses

Hoses should be rated for a minimum of 250 psi (17.2 bar). Before connecting the air hose to the tool, check the tool inlet connector to be sure it is clean and free of dirt or debris. Keeping dirt and debris from entering the tool will assure long and satisfactory operation.
