An integrated mechanical fuel pump employs a unique system that maintains constant pressure to the regulator without electricity. The PROi is designed with a custom electronic fuel injection system that uses just 3 psi, 40 psi less than standard EFI systems.
Hand-arm low vibration levels on 3 axes is below 4 m/s2 to minimize operator fatigue. The light, compact machine weighs just 53 pounds, so users can easily move and transport it in a car’s trunk. The 2-stroke, 90cc engine delivers as much as 44 foot-pounds of breaking force due to the arrangement of the gearbox percussion system, this force is equivalent to 793 pounds hitting the chisel every second.
Rather than having the trigger with the kill switch on the left handle, Atlas Copco moved it to the right and made it a button not a lever. The button also automatically presses back out, eliminating the risk of remaining in the ‘off’ position, which would prevent the operator from starting the unit.
