Stihl MS 500i Petrol Chainsaw

STIHL MS 500i Petrol Chainsaw – Available to Buy in Dublin

The STIHL MS 500i petrol chainsaw is an exceptionally powerful professional forestry chainsaw designed for felling, cross-cutting and processing large timber.

Featuring STIHL’s electronically controlled fuel-injection technology, the MS 500i delivers extremely fast acceleration, outstanding cutting performance and excellent power for its relatively low weight.

This professional STIHL chainsaw is available to purchase from A-Z Hire in Walkinstown, Dublin 12.

Professional Fuel-Injected STIHL Chainsaw

The STIHL MS 500i was the world’s first production chainsaw equipped with electronically controlled fuel injection.

Its intelligent injection system continuously monitors operating conditions and calculates the correct fuel supply and ignition timing. This allows the engine to respond quickly while maintaining consistent performance during demanding cutting work.

There is no conventional choke starting position. The simplified starting procedure makes the saw easier to start in a wide range of working and weather conditions.

Exceptional Power-to-Weight Performance

Powered by a high-performance 79.2 cm³ STIHL 2-MIX engine, the MS 500i produces an impressive 5.0 kW or 6.8 hp.

The powerhead weighs just 6.3 kg without the guide bar, chain or fuel, giving the MS 500i an exceptional power-to-weight ratio of approximately 1.24 kg/kW.

This combination of high power, low weight and rapid acceleration makes the MS 500i particularly suitable for professional forestry contractors, tree surgeons, arborists and experienced chainsaw operators working with large hardwood and mature timber.

STIHL Ematic Chain Lubrication System

The STIHL Ematic system directs chain oil to the areas where lubrication is required most.

When used with the appropriate STIHL Ematic guide bar and STIHL Oilomatic saw chain, the system can considerably reduce unnecessary chain-oil consumption while maintaining effective bar and chain lubrication.

The adjustable oil pump also allows the operator to increase oil delivery when working with longer guide bars or in particularly dusty conditions.

Additional STIHL MS 500i Features

Side-Mounted Chain Tensioning

The chain tensioning screw is conveniently positioned on the side of the chainsaw. This allows the chain to be adjusted without working close to the sharp cutting teeth.

Captive Bar Nuts

The nuts remain attached to the sprocket cover when it is removed, reducing the chance of losing them during chain replacement or maintenance.

Optimised Sprocket Cover

The narrow sprocket cover supports efficient chip clearance and makes it easier to guide the saw close to the timber during delimbing.

Optimised Bumper Spikes

The shaped bumper spikes provide a secure grip against the timber, improving control when felling or cross-cutting large logs.

Manual Decompression Valve

The decompression valve reduces cylinder compression during starting, lowering the pulling force required on the starter cord.

STIHL Anti-Vibration System

Special spring and buffer elements reduce the amount of engine vibration transferred to the handles. This improves operator comfort during extended periods of professional cutting.

Tool-Free Fuel and Oil Caps

The bayonet-style caps can be opened and securely closed without additional tools, making refuelling and chain-oil filling quicker.
