Perfectly balanced handling combined with rugged build-quality and a top-handle-type configuration make the Italian-engineered Oleo-Mac GST250 Petrol Chainsaw a great choice for the professional arborist.

It comes driven by a powerful 25.4cc two-stroke air-cooled engine that produces a substantial 1.2hp, and which employs Oleo-Mac’s EasyOn technology for a smooth pick-up with no danger of ‘kick back’.

No-tools filter-cover removal makes day-to-day maintenance that much easier; a roomy 0.23-litre fuel tank serves to reduce time lost due to refuelling stops.

The Oleo-Mac GST-250 Top-Handle Petrol Chainsaw’s compact design, optimised centre of gravity and ultra-lightweight build (2.8kg) all work to make it highly manoeuvrable, and therefore ideal for space restricted, in-tree work.

It incorporates a lateral chain tensioner, which makes it quick and simple to adjust the chain if you are in an awkward operation position, and it’s fitted with a belt hook for safe climbing into tree canopies.

So as to ensure varying wood types, oils and weather conditions can be managed, the Oleo-Mac GS-260 Top-Handle Petrol Chainsaw has been equipped with a fully adjustable chain lubrication system.

Also important is the cushioned handle that minimises vibration transfer to the user’s arms and hands.

Shipping Info

Shipping Info

If you’re buying a boxed product, we aim to get your order delivered next working day – UK mainland where possible.

If you’re buying a tractor or ride-on mower – a special order item – it could be slightly longer, as we need to PDI the machine.

We do try and van-deliver these machines if we can, as this gives us a chance to demonstrate the product, and to ensure you’re happy and confident with your purchase.

If we can’t van-deliver your machine, as you’re out of our local delivery area, the tractor will be sent on a pallet via a courage company. They will then contact you directly to book a specific day and time that suits you.
