Stihl MSA 300 R cordless rescue chainsaw – 50 cm / 20″

The STIHL MSA 300 R cordless rescue chainsaw is built for professionals in fire, emergency, and rescue work who need instant power without the drawbacks of petrol. Supplied as a tool-only unit, it’s fitted with a 50cm Rollomatic ES Rescue guide bar and a Rapid Duro Rescue chain to cut through wood, roofing, composites, aluminium, and even glass.

Running on the AP 500 S battery, it delivers a full 3.0 kW output with three selectable operating modes for precise control in demanding conditions. Low maintenance, heat-resistant housing and all-weather IPX4 protection make it a dependable choice for crews who can’t afford downtime.

For those who prefer petrol power, there’s also the STIHL MS 462 C-M R 50 cm (20″) petrol rescue chainsaw—compatible with the same cutting attachments as the MSA 300 R and popular among professional rescue teams. View it here.

Built for Demanding Rescue Operations

The MSA 300 R combines the cutting performance emergency teams expect from STIHL with the advantages of battery power. There’s no cold start delay, no exhaust fumes, and minimal upkeep — all critical when seconds count. Its reinforced, heat-resistant housing is made to withstand high temperatures and rough handling on site.

Key Strengths

• Three operating modes – Eco for extended runtime, Felling for maximum torque, and Delimbing for high-speed precision cuts.
• Rapid Duro Rescue chain – Carbide-tipped teeth stay sharp cutting abrasive materials that would blunt a standard chain.
• Rollomatic ES Rescue guide bar – Built to handle high stress, fitted with a depth limiter for safer plunge cuts.
• 3.0 kW electrical power – Matches petrol rescue saw performance when paired with the AP 500 S battery.
• All-weather capability – IPX4 splash protection means reliable operation in heavy rain.

Who It’s For

Designed for professional rescue crews, fire brigades, and specialist emergency teams who need to cut through varied materials quickly and safely. Ideal for teams already invested in the STIHL AP System who want a dedicated rescue tool without running petrol equipment.

Compatible Accessories

• STIHL AP 500 S battery – required for full power output
• AL 500 quick charger or other AP System chargers
• Spare Rapid Duro Rescue chains
• STIHL Varioclean for air filter maintenance

What Pros Use: Batteries & Charging Gear

Experts on rescue and emergency teams don’t compromise on runtime or reliability. They pair the MSA 300 R with the high-capacity AP 500 S battery (sold separately) to pull full 3 kW and up to 44 minutes runtime. To keep multiple batteries charged between jobs or overnight, they use modular charging setups built for vehicles and workshops.

Essential Battery & Charger Setup

• AP 500 S battery – required for full saw output and longest runtime.
• AL 301-4 multi-battery charger – sequentially charges up to four AP batteries; wall, shelf or vehicle-mountable, with active cooling and LED indicators. :contentReference[oaicite:1]{index=1}
• CB 1 charging box – mobile, lockable aluminium box mounts under vehicle or on trailer. Holds up to eight AP batteries and two AL 301-4 chargers, IPX4-rated. :contentReference[oaicite:2]{index=2}
• AL 501 Hi-Speed charger – for very fast single-battery recharge (not tabled)—kept on base for emergencies.

Runtime & Charge Times (AP System)

Why This Setup Works for Pros

• Mobile charging and storage. CB 1 cuts downtime by letting teams drive off with fully charged batteries—for continuous operations.
