GHS 400 has an engine with 2 piston rings, forged and machined steel crankshaft, needle roller bearings, and nickel-plated cylinder to guarantee constant efficiency over time, also in the case of heavy-duty use.
Lateral chain tensioner: simplifies tensioning adjustments while avoiding any risk of contact with the chain.
Adjustable aluminum oil pump: facilitates the operator’s job by allowing the oil feed to be adjusted to suit the workload on the tool and the bar/chain combination.
Zero oil flow with the engine at idling speed ensures lower consumption and reduced environmental impact.
