User Friendly
The M57 offers a wide array of features that make it very user-friendly. Units come standard with an easy to read control panel including a push-to-load switch. The large fuel tank provides extended operation and has a large filler neck with overflow protection for safe, easy filling. The lifting eye and height adjustable hitch and rigid tow bar also make transporting the M57 easy. A torsion bar suspension system and oversized tires provide superior road handling. The canopy is also super-soundproofed and provides extremely low decibel levels. Maximum sound level measured at 23 feet is 76 dbA.

Efficient and Reliable
A heavy-duty 4-cylinder engine combined with energy saving Sigma Profile airend produces more air with less horsepower. A high capacity cold start battery ensures reliable operation even under extreme conditions and a proprietary anti-frost thermostatic valve eliminates tool freeze up. The M57's heavy-duty steel chassis and powder coated canopy ensure smooth operation even when subjected to the harshest conditions. Both the canopy and solid steel flooring protect the motor, airend, and critical components from dirt, water, and other contaminants. Engine and compressor inlets are filtered with maintenance indicators. This protection, combined with a high efficiency cooling system allows the M57 to operate in ambient temperatures up to 122°F.
