Product details and specs

One of the largest and most powerful homeowner-use petrol chainsaws available, the high-performance Alpina ACS 552 is ideal for heavier-duty felling and log preparation applications!
The brand-new 52cc two-stroke air-cooled engine on the ACS 552 might be powerful – it develops a huge 2.3kW (3.1hp) – but, thanks to cutting-edge combustion technology, it runs around 60% cleaner and 20% more efficiently than lower-specification units of comparable size.
Also featured on the engine is a decompression valve that drastically reduces the pulling-force required to get started (auto-choke contributes further to ease of starting).
The ACS 552 has a magnesium crankcase that not only serves to minimise machine-weight, but also reduces running temperature for a longer component life.
Despite its sizeable engine, the ACS 552 excels when it comes to user comfort, with its lightweight build, ergonomic handle configuration, anti-vibration system and sift-touch grips all combining to make it a pleasure to work with.
As simple to maintain as it is comfortable to use, the ACS 552 features straightforward side chain-tensioning, a tool-free air-filter cover and an easy-fill oil tank.
Other attractive features include a quick-stop, dual-action chain break that confers excellent operator safety; and a practical fuel-tank vision window for at-a-glance level checking.
This model is supplied with an expansive 50cm guide-bar from high-end US manufacturers Oregon.
