ACS 546 (18)"

The 46.5cc ACS 546 weighs only 6.8kg and features a 2kW two-stroke engine. Supplied with a 45cm guide-bar.
  • check Powerful but clean-burning and efficient 46.5cc/2kW air-cooled two-stroke engine
  • check 45cm guide-bar – suitable for larger cuts
  • check Lightweight design – just 6.8kg
  • check Capacious oil/fuel tanks keep downtime to a minimum (0.26L/0.47L)
This premium-range petrol chainsaw offers a desirable combination of powerful performance, lightweight handling and simplicity of use, all at an affordable price-point!
At the heart of the Alpina ACS 546 is a 46.5cc two-stroke air-cooled engine that’s rated at a sizeable 2kW (2.7hp); and which features an auto-choke system for fast, no-hassle starting.
Brand-new combustion technology ensures efficient, low-emission operation with 20% less fuel-consumption and a 60% cut in unburnt hydrocarbons.
The ACS 546 ticks all the boxes in terms of user-safety, with its quick-stop chain brake – triggered either manually or by inertia – bringing the chain to a halt in a split second when activated.
A weight-reducing magnesium crankcase works to minimise running temperature and extend component life; while a soft-touch grip combines with the machine’s low-weight build, anti-vibration system and ergonomic handle configuration to confer excellent operator comfort.
Easy to maintain, the ACS benefits from straightforward side chain-tensioning and features an easy-fill chain-oil tank (the automatic oil-pump can be adjusted to suit the timber-type).
Other desirable features include a convenient multi-function handle and a handy fuel-tank vision window.
This model’s lengthy 45cm guide-bar makes it suitable for tackling larger logs and timbers.
