What is the STIHL GS 461 ROCK BOSS?
The STIHL GS 461 ROCK BOSS is a professional gas-powered concrete cutter that uses a diamond abrasive chain to cut concrete, masonry, asphalt and soft stone.

Who is the STIHL GS 461 best suited for?
It is designed for construction crews, concrete contractors, masons, utility workers and professionals who need deep, precise cuts in hard materials.

What materials can the STIHL GS 461 cut?
It can cut concrete, reinforced concrete, cinder blocks, masonry bricks, asphalt and soft stone.

Can the STIHL GS 461 cut reinforced concrete?
Yes. It can cut reinforced concrete containing rebar up to approximately 1/2 inch.

How deep can the STIHL GS 461 cut?
It can cut to a maximum depth of approximately 15.7 inches when equipped with the recommended cutting setup.

What guide bar length is recommended for the GS 461?
The recommended guide bar length is 16 inches.

What type of chain does the STIHL GS 461 use?
It uses a specialized STIHL 3/8-inch 36 GBM Diamond Abrasive Chain.

Can a regular chainsaw chain be used on the GS 461?
No. It requires the correct diamond abrasive chain and compatible guide bar designed for concrete cutting.

What is the advantage of a diamond abrasive chain?
It allows the cutter to make deep, controlled cuts and work into corners where some circular cut-off machines may be limited.

What type of engine does the STIHL GS 461 use?
It uses a 76.5cc gas-powered STIHL engine.

How much power does the GS 461 produce?
The engine produces approximately 5.8 bhp.

How much does the STIHL GS 461 weigh?
The listed powerhead weight is approximately 16.8 lb without the guide bar, chain, fuel or water supply.

Is the STIHL GS 461 easy to maneuver?
Its compact handheld design provides more maneuverability than many larger concrete-cutting machines, although it remains a powerful professional tool.

Does the STIHL GS 461 require water while cutting?
Yes. Water should be supplied through the integrated connection during cutting to cool the chain and help control dust.

What type of water connection does it use?
It includes a quick-connect water fitting with a shut-off valve.

Why is water important when using the GS 461?
Water cools and lubricates the cutting system, reduces abrasive wear and helps suppress hazardous silica dust.

Can the GS 461 be used for dry cutting?
It is designed for wet cutting. It should not be operated without the required water supply unless specifically permitted by STIHL instructions.

Does the STIHL GS 461 have an anti-vibration system?
Yes. The anti-vibration system helps reduce the amount of vibration transferred to the operator.

Why is reduced vibration important?
It can improve comfort and control while helping reduce fatigue during demanding cutting work.

What is STIHL ElastoStart?
STIHL ElastoStart uses a shock-absorbing starter grip to reduce the sudden forces felt while pulling the starter cord.

Does the GS 461 have a decompression valve?
Yes. The decompression valve reduces cylinder pressure during starting, making the starter rope easier to pull.

What is the IntelliCarb compensating carburetor?
IntelliCarb automatically adjusts the fuel mixture as the air filter becomes restricted, helping maintain engine performance.

What is the HD2 filter system?
The HD2 system uses a long-life pleated air filter and a secondary filter to provide improved protection in dusty construction environments.

Can the HD2 filter be cleaned?
The filter can be serviced according to STIHL instructions. It should be inspected regularly and replaced if damaged or excessively worn.

What is the upright filter cap?
It is designed to help keep dust away from the fuel opening while allowing the machine to be refuelled in an upright position.

What is the bayonet-style filler cap?
It is a tool-free fuel cap designed for easy opening and closing, even while wearing gloves.

What is the rubber bumper used for?
The bumper helps protect the front of the engine housing when the cutter is positioned against the workpiece.

What is the fuel capacity of the STIHL GS 461?
The fuel tank holds approximately 26.4 oz.

Does the STIHL GS 461 require mixed fuel?
Yes. It uses gasoline mixed with approved two-stroke engine oil according to STIHL specifications.

Can straight gasoline be used in the GS 461?
No. Straight gasoline can cause serious engine damage.

Does the STIHL GS 461 produce exhaust emissions?
Yes. It is gas powered, although it uses a low exhaust emission engine design.

Can the STIHL GS 461 be used indoors?
Gas-powered equipment should not be operated in enclosed spaces without an approved ventilation and exhaust-control plan.

What safety equipment should be worn?
Operators should use eye, hearing and respiratory protection, a hard hat, gloves, protective footwear and suitable cut-resistant work clothing.

Is silica dust a hazard when cutting concrete?
Yes. Concrete and masonry cutting can release respirable crystalline silica, so wet-cutting methods and appropriate respiratory protection are essential.

Should the cutting area be inspected before work begins?
Yes. Confirm the location of electrical wiring, plumbing, gas lines, structural reinforcement and other hidden hazards before cutting.

Can the STIHL GS 461 be used for plunge cuts?
Its chain-based design can perform controlled plunge and corner cuts when used by a trained operator following STIHL procedures.

Can the GS 461 cut square openings?
Yes. Its guide-bar design makes it useful for creating rectangular openings and cutting into corners.

What maintenance does the STIHL GS 461 require?
Routine care includes inspecting the diamond chain, guide bar, sprocket, water system, air filters, starter, spark plug and fuel system.

How should the diamond chain be maintained?
Keep it properly tensioned, ensure the water supply is functioning and inspect the diamond segments and drive links for wear or damage.

Should the machine be cleaned after cutting?
Yes. Concrete slurry and abrasive residue should be removed before they harden around the bar, chain, sprocket and water fittings.

Are the listed dimensions complete?
No. The secondary table lists zero values for width, height and length. Those values should be removed or confirmed before publishing.

What are the main benefits of the STIHL GS 461 ROCK BOSS?
Its main benefits include a 15.7-inch cutting depth, diamond-chain precision, the ability to cut reinforced concrete and a compact professional design.
