The Mitox 455CSX Premium is a superior chainsaw for all round general domestic use featuring a quality 45cm (18") Oregon guide bar and chain. A built-in side tensioner is neatly located between the chain cover bolts.

The 45.4cc engine is easy to start thanks to the spring damper recoil assist system and produces an impressive power output of 1.95kW for effective cutting. 

Comfort during operation is enhanced via the anti-vibration front and rear handles. Large durable triggers make the machine easier than ever to use and its integrated soft grip is comfortable and practical. The extra wide rear handle base provides protection for the rear hand and also houses an integrated tool for spark plug and chain cover removal. Maintenance access is quick and easy as the cover can be removed without tools.

A lighweight magnesium crankcase has numerous benefits including better heat dissipation properties than traditional aluminium. 

Safety when using a chainsaw is paramount, and the 455CSX features a completely redesigned chain brake system on board, with twin mounting point for durability and strong and positive engagement.

The rear-mounted fuel tank features an integrated window so you can clearly see the fuel level in use.

A well-balanced chainsaw weighing 5.7kg, the Mitox 455CSX Premium is backed by a comprehensive five year manufacturer's warranty for domestic use.

Quality Oregon Cutting Gear

As with all Mitox Premium petrol chainsaws, the 455CSX comes equipped with a high quality Oregon guide bar and saw chain offer maximum cutting performance and durability.

Quick and Easy Maintenance Access

The quick access cover for the air filter and spark plug can be removed without tools enabling basic maintenance to be completed in a few minutes.

Chain Brake System

To reduce the chance of injury, the safety chain brake stops the chain within 0.15 seconds. The chain brake can be activated manually, or by inertia in the event of a kick-back. The new chain brake features twin mounting points for improved strength and durability.

Fuel Tank Window

The rear-mounted fuel tank features an integrated window which enables the user to see the fuel level clearly.

Wide Rear Handle with Integrated Tools

The extra wide base of the rear handle not only provides protection for your hand but also houses an integrated tool for spark plug and chain cover removal.

Simple Starting
