Husqvarna FS 413: Complete Guide to Specifications, Cutting Depth, Blades, Uses, and Maintenance

The Husqvarna FS 413 is a compact, professional walk-behind floor saw designed for cutting concrete and asphalt on small to medium-sized construction, repair, and maintenance projects. With an 11.7-horsepower gasoline engine, maximum 20-inch blade capacity, and cutting depth of up to 7.6 inches, the FS 413 provides substantial cutting capability without the size and complexity of a larger self-propelled road saw.

The Husqvarna FS 413 is especially well suited for concrete contractors, paving crews, municipalities, rental companies, utility contractors, landscapers, and construction professionals who need a portable floor saw for jobs such as pavement repair, concrete slab cutting, trench work, expansion joints, and asphalt patching.

The current U.S. configuration is a petrol-powered push floor saw featuring a Honda engine. Husqvarna lists the FS 413 at 11.7 hp with a maximum 20-inch blade and 7.6-inch maximum cutting depth.

What Is the Husqvarna FS 413?

The Husqvarna FS 413 is a push walk-behind flat saw, sometimes called a floor saw or concrete saw.

Unlike a handheld power cutter, a floor saw runs on wheels and allows the operator to guide the diamond blade along a predetermined cutting line.

This configuration is useful for creating long, straight cuts in horizontal surfaces.

Typical FS 413 applications include:

  • Concrete slab cutting

  • Asphalt cutting

  • Driveway repair

  • Sidewalk repair

  • Parking lot work

  • Road patching

  • Expansion joints

  • Utility trenches

  • Drain installation

  • Concrete removal

  • Pavement repair

  • Commercial construction

Its compact design makes it particularly useful where a larger floor saw would be unnecessarily difficult to transport or maneuver.

Husqvarna FS 413 Specifications

The current U.S. Husqvarna FS 413 has several important specifications contractors should know.

Power source: Petrol

Engine power: 11.7 hp

Engine: Honda

Maximum blade diameter: 20 inches

Maximum cutting depth: 7.6 inches

Current U.S. article number: 965 15 01-07

The current U.S. configuration is offered without an integrated water tank, although a compatible water tank kit is available as an accessory.

Specifications can vary by market and production year, so buyers looking for replacement parts or accessories should verify the complete product and serial numbers on their individual machine.

How Deep Does the Husqvarna FS 413 Cut?

The Husqvarna FS 413 has a maximum listed cutting depth of 7.6 inches.

That is substantial cutting capacity for a relatively compact push saw.

This depth makes the FS 413 useful for jobs involving:

  • Thick concrete slabs

  • Deep pavement cuts

  • Utility access

  • Concrete removal

  • Asphalt repair

  • Expansion joints

  • Drainage modifications

Maximum depth does not mean every project should be completed in a single pass.

When cutting thick or heavily reinforced concrete, multiple controlled passes can reduce strain on the blade and saw.

What Size Blade Does the Husqvarna FS 413 Use?

The maximum blade diameter for the FS 413 is 20 inches.

The saw may also operate with smaller compatible blades when configured according to manufacturer requirements.

Diamond blade selection should consider more than diameter.

Important factors include:

  • Arbor size

  • Maximum RPM

  • Concrete hardness

  • Aggregate

  • Reinforcement

  • Asphalt abrasiveness

  • Cutting depth

  • Wet or dry operation

  • Required cutting speed

A blade that physically fits the machine is not necessarily the correct blade for the material.

Husqvarna FS 413 Diamond Blades

The FS 413 is designed to work with professional diamond blades selected according to the cutting application.

Husqvarna currently identifies compatible blades across several of its professional blade families for materials including concrete and asphalt.

The blade bond and segment design should match the material being cut.

Concrete Diamond Blades

For cured concrete, blade selection depends heavily on aggregate hardness.

Hard aggregate generally requires a softer blade bond that allows the segment matrix to wear and expose fresh diamonds.

Softer, abrasive material usually requires a harder bond to prevent excessively fast wear.

Asphalt Diamond Blades

Asphalt is highly abrasive.

A dedicated asphalt blade normally uses a harder bond and may incorporate undercut protection around the segment area.

Using the wrong concrete blade repeatedly in asphalt can result in extremely short blade life.

Reinforced Concrete Blades

Concrete containing rebar or wire mesh should be cut with a blade rated for reinforced concrete.

Reinforcement increases the load on the blade and can generate additional heat.

Maintain steady feed pressure rather than forcing the blade through steel.

Cutting Concrete With the FS 413

Concrete cutting is one of the primary applications for the FS 413.

The saw can be used for:

  • Slab removal

  • Concrete repairs

  • Floor modifications

  • Expansion joints

  • Utility trenches

  • Drain installation

  • Demolition preparation

  • Driveway work

  • Sidewalk repair

The wheeled design makes it easier to maintain a straight line than cutting a long section entirely with a handheld saw.

Before cutting, mark the line clearly and align the front pointer with the blade.

Lower the blade gradually into the concrete rather than dropping it aggressively into the surface.

Cutting Asphalt With the FS 413

The FS 413 is also suitable for asphalt cutting when equipped with the correct blade.

Applications include:

  • Parking lot repairs

  • Road patching

  • Utility trenches

  • Asphalt removal

  • Driveway repairs

  • Drainage projects

Asphalt is generally softer than concrete but considerably more abrasive.

Selecting an asphalt-specific blade is important for controlling segment wear.

Push Floor Saw Design

The FS 413 is a push walk-behind saw, not a self-propelled model.

This means the operator manually controls forward movement.

For smaller and medium-sized jobs, this has several advantages.

A push design can provide:

  • Simple operation

  • Lower mechanical complexity

  • Easy maneuverability

  • Reduced maintenance

  • Compact dimensions

  • Easier transportation

For extremely long cuts or high-production highway work, a larger self-propelled saw may be more appropriate.

IntelliSeal Blade Shaft

One of the important FS 413 features is Husqvarna's IntelliSeal blade shaft system.

According to Husqvarna, the system provides a minimum of 250 maintenance-free operating hours without requiring daily greasing of the blade-shaft bearings.

This is particularly useful for contractors and rental fleets because the blade shaft is one of the most heavily loaded systems on a concrete saw.

Reducing daily maintenance can help improve uptime while decreasing the chance that lubrication requirements are overlooked.

Low-Vibration Design

Husqvarna designed the FS 413 with an engine and blade-shaft mounting system intended to reduce vibration.

Reduced vibration can improve:

  • Operator comfort

  • Cutting control

  • Blade performance

  • Straight-line accuracy

  • Productivity

However, sudden or excessive vibration should always be investigated.

Potential causes include:

  • Damaged diamond blade

  • Blade installed incorrectly

  • Dirty flanges

  • Worn bearings

  • Bent blade shaft

  • Loose hardware

  • Uneven blade wear

Stop the saw immediately if unusual vibration develops.

Spring-Assisted Blade Adjustment

The FS 413 uses a spring-assisted screw-feed system to help raise and lower the blade.

This provides controlled adjustment as the operator enters or exits the cut.

Gradual blade engagement is important because forcing a full-speed diamond blade aggressively into concrete can create:

  • Segment damage

  • Blade deflection

  • Belt strain

  • Engine load

  • Excessive vibration

Controlled depth adjustment also makes multiple-pass cutting easier.

Clear Cutting-Depth Indicator

The FS 413 includes a depth indicator that can be adjusted for different blade diameters.

Knowing the approximate blade depth is useful when:

  • Cutting expansion joints

  • Avoiding embedded utilities

  • Making repeated passes

  • Cutting to a specified depth

  • Preventing unnecessary overcutting

Operators should still understand the structure being cut and identify potential embedded hazards before starting.

Adjustable Handles

The FS 413 features adjustable handles that allow the operator to work closer to the cutting side of the machine.

This can improve visibility of the:

  • Cutting line

  • Front pointer

  • Blade position

  • Work surface

The handle can also fold for transportation.

This is especially useful for contractors who regularly load the saw into trucks, trailers, or equipment vans.

Transporting the FS 413

The FS 413 is designed to be relatively easy to transport compared with larger road saws.

Its compact dimensions make it a practical choice for:

  • Rental fleets

  • Service contractors

  • Small construction crews

  • Municipal maintenance teams

A lifting bail is available as an accessory for appropriate mechanical lifting.

When transporting the saw:

  • Secure it with appropriate tie-downs.

  • Keep the blade raised.

  • Remove the blade when required.

  • Shut off the fuel supply when specified.

  • Prevent the saw from rolling.

  • Protect controls from impact.

Never lift the saw using components not designed as lifting points.

Water Tank Kit

A compatible water tank kit is available for the FS 413.

Water is important during wet concrete cutting because it helps:

  • Cool the diamond blade

  • Reduce airborne dust

  • Remove cutting debris

  • Control slurry

  • Reduce blade temperature

When an external pressurized water source is available, it may also be connected according to the machine's approved setup.

Maintain enough water flow to reach the blade consistently.

Wet Cutting With the FS 413

Wet cutting is common when using a floor saw.

Before beginning:

  1. Check the water supply.

  2. Inspect hoses.

  3. Check fittings.

  4. Confirm water reaches the blade.

  5. Start water flow before entering the concrete.

Insufficient water can cause the blade to overheat and may substantially reduce blade life.

Dry Cutting With the FS 413

Dry cutting should only be performed when the blade, machine setup, cutting procedure, and dust-control system permit it.

Concrete and masonry can contain crystalline silica.

Dry cutting can create substantial airborne dust, so appropriate engineering controls and personal protective measures are essential.

Never operate a wet-only diamond blade dry.

Husqvarna FS 413 Maintenance

Routine maintenance helps keep the saw cutting efficiently.

Important areas include:

  • Engine oil

  • Air filter

  • Spark plug

  • Fuel system

  • Drive belts

  • Blade shaft

  • Blade flanges

  • Wheels

  • Water system

  • Controls

  • Fasteners

  • Blade guard

Concrete slurry should be removed after each job.

Allowing slurry to harden around moving parts can make future maintenance considerably more difficult.

FS 413 Drive Belt Maintenance

Drive belts transfer engine power to the blade shaft.

Inspect them for:

  • Cracking

  • Fraying

  • Glazing

  • Stretching

  • Missing material

  • Oil contamination

  • Uneven wear

A slipping belt reduces blade speed.

This can make even a new diamond blade appear to cut poorly.

Correct belt tension is also important because excessive tension can place unnecessary load on the blade-shaft bearings.

Blade Flange Maintenance

Blade flanges hold the diamond blade securely against the arbor.

Before installing a blade:

  • Clean both flanges.

  • Remove slurry.

  • Inspect for damage.

  • Check the arbor.

  • Confirm correct blade orientation.

  • Tighten hardware properly.

A dirty or damaged flange can cause blade wobble.

Why Is My Husqvarna FS 413 Cutting Slowly?

Slow cutting may be caused by:

  • Incorrect diamond blade

  • Glazed blade segments

  • Worn blade

  • Slipping drive belts

  • Low engine speed

  • Excessive cutting depth

  • Hard aggregate

  • Poor water flow

  • Excessive forward pressure

Pushing harder is rarely the correct solution.

A diamond blade needs adequate blade speed to cut efficiently.

FS 413 vs FS 400 LV

The FS 413 and FS 400 LV are both current Husqvarna push walk-behind floor saws with 11.7-hp petrol engines and maximum 20-inch blade capacity.

The FS 413 has a maximum listed cutting depth of 7.6 inches, while the FS 400 LV is listed at 7.5 inches.

Both are positioned for compact concrete and asphalt cutting applications, but individual features, water configurations, dimensions, and accessories should be compared before purchasing.

FS 413 vs FS 513

The FS 413 and FS 513 both currently use 11.7-hp petrol power and accept blades up to 20 inches.

The major distinction is the drive configuration.

The FS 413 is a push saw, while the FS 513 is a self-propelled walk-behind saw.

The FS 413 may be preferable for contractors who prioritize simplicity, maneuverability, and lower mechanical complexity.

The FS 513 may be better for longer cuts where powered forward travel reduces operator effort.
