The Oleo-Mac GST 250 is a professional chainsaw characterised by an excellent combination of power, lightweight construction, balanced geometry and easy handling. Combined, these elements make this the perfect tool for professional pruning and maintenance services on trees over extended operating periods. 

Engineering improvements combined with new features make it well worth taking a second look at this lightweight pruning saw. For instance, newly-designed handles, fuel pipelines and inlet manifold allow easy operation at any angle. The new geometry of the brake-band housing in the chain guard means clogged sawdust needs to be removed less frequently. And an automatic aluminium oil pump, with adjustable flow, allows variation of lubricant flow to match conditions. It is driven by the clutch housing, so delivers zero oil flow with the engine idling.

Powered by a 1.3hp / 25.4cc engine, the GST 250 top handle saw features Oleo-Mac's 'EasyOn' starting system which ensures a smooth pick-up of the engine with no kickback and a limited number of pulls. Equipped with a 25cm (10") guide bar, the lateral chain tensioner allows the operator to adjust the chain tension swiftly, even in tricky positions. The metal oil pump with adjustable flow rate lets the flow rate of the lubricant be adapted based on the different types of use (type of wood, weather conditions, type of oil). The filter is removable without tools for easy maintenance.

The Oleo-Mac GST 250 features a specific hook which allows the operator to hang the chainsaw from a belt for unimpeded access to branches which are hard to reach. The cushioned operating handle means the carburetor is not subject to vibrations, ensuring a high degree of carburation so the job can be performed comfortably in all work positions.

This chainsaw must be used only for tree surgery by certified tree surgeons.
