FAQ

What engine powers the 2008 Somero S-840 Laser Screed and what is its fuel capacity? +

The 2008 Somero S-840 Laser Screed is equipped with a 20.5 horsepower air-cooled gasoline engine. Models have featured either a Subaru EH65 or Robin America EH64 2-cylinder engine. The fuel capacity is 4.25 gallons, which provides several hours of operation depending on workload. Some later models offer an optional diesel engine (24.8 HP Kubota DH902) for extended runtime and fuel efficiency.

What are the dimensions and weight of the 2008 Somero S-840 Laser Screed? +

The 2008 Somero S-840 Laser Screed measures approximately:

  • Width: 3 feet 6 inches (1.1 m) in transport mode
  • Length: 9 feet 7 inches (2.9 m) with standard screed head
  • Weight: 1,548 lbs (702 kg)

These compact dimensions allow the machine to fit through standard doorways and access tight job sites while being easily transported on a flatbed truck or tag-behind trailer.

What screed head widths are available? +

The 2008 Somero S-840 Laser Screed offers three interchangeable head options:

  • Screed Head: 6-foot or 8-foot width with offset auger design
  • Raking Head: 6-foot or 8-foot width for spreading and leveling
  • Sub-Grade Head: For fine grading of sub-base material

The offset auger design on the screed head allows for one-person operation without requiring additional rakers.

What is the production rate of the 2008 Somero S-840 Laser Screed? +

The 2008 Somero S-840 Laser Screed can screed up to 5,000 square feet per hour on average. Actual production rates depend on factors such as concrete slump, slab thickness, site conditions, operator experience, and whether you’re working on ground level or elevated decks. For complete specifications, visit the official page from the manufacturer.

What concrete slump range can the 2008 Somero S-840 Laser Screed handle? +

The machine works effectively with concrete slumps as low as 3.5 inches (8.9 cm), making it versatile for various concrete mixes. This low-slump capability is particularly valuable for industrial floors and warehouse applications where stiffer concrete is often specified for durability and flatness.

What flatness can I expect to achieve with the 2008 Somero S-840 Laser Screed? +

The 2008 Somero S-840 Laser Screed is designed to exceed standard flatness and levelness specifications. With its integrated laser control system, the machine automatically maintains grade to achieve superior FF (Floor Flatness) and FL (Floor Levelness) numbers compared to manual screeding methods. The exact numbers depend on concrete quality, placement conditions, and operator skill.

What types of projects is the S-840 best suited for? +

The S-840 excels at:

  • Commercial warehouse floors
  • Industrial slabs-on-grade
  • Retail space concrete floors
  • Parking structures
  • Loading docks and service areas
  • Projects requiring high flatness specifications
  • Jobs where space constraints prevent larger equipment access

It’s particularly effective for contractors working on small to medium-sized pours where a larger screed would be impractical.

Can the S-840 screed over rebar and heat tubes? +

Yes. The auger screed head can work over:

  • Chaired mesh reinforcement
  • Chaired rebar
  • Radiant heat tubes
  • Some slab-on-deck applications

The machine’s hydraulic system controls the elevation of the auger to maintain grade even when working over obstacles, providing a smoother surface than rigid-mounting machines.

Is the S-840 compatible with 3D profiling systems? +

Yes, the S-840 is fully compatible with Somero’s 3-D Profiler System. This allows the machine to create complex multi-slope surfaces for parking lots, loading docks, and outdoor paving applications using robotic total station technology for precise grade control

How many operators are required to run the S-840? +

The S-840 is designed for single-operator use. The offset auger head design eliminates the need for additional personnel to manually rake concrete behind the screed. This significantly reduces labor costs compared to traditional screeding methods, which typically require multiple workers. Browse our complete selection of concrete batch plants for sale to compare different capacity options for your project needs.

What tire options are available and why do they matter? +

The S-840 offers two tire configurations:

  • Standard tires: 38 PSI (262 kPa) ground contact pressure
  • Optional ATV-style wide flotation tires: 9.8 PSI (67.6 kPa) ground contact pressure

The low-pressure ATV tires are ideal for working on softer sub-grades or when you need to minimize ground disturbance. They also provide better traction in wet concrete.

What routine maintenance does the S-840 require? +

Regular maintenance includes:

  • Daily: Check engine oil, fuel level, hydraulic fluid, and tire pressure
  • Weekly: Clean air filter, inspect screed head for wear
  • Every 50 hours: Change engine oil and filter
  • Every 100 hours: Lubricate all grease points, inspect hydraulic hoses
  • Annually: Complete hydraulic system service, laser calibration check

The OASIS control system includes live calibration features that help maintain consistent performance between service intervals.

What trailer or truck is needed to transport the S-840? +

At 1,548 lbs and compact dimensions (3’6″ wide x 9’7″ long), the S-840 can be transported on:

  • Standard flatbed truck (no special permits required)
  • Tag-behind equipment trailer
  • Enclosed trailer (for weather protection)

Many contractors use a dedicated equipment trailer (such as Karavan brand) that allows for easy loading/unloading via ramps. No special hauling permits are typically required due to the machine’s weight and size.

Does the S-840 require special setup or calibration on-site? +


2008 Somero S-840 Laser Screed Setup is straightforward:

  1. Position laser transmitter at appropriate location
  2. Power on the OASIS control system
  3. Perform quick grade set calibration (Somero Quick GradeSet System)
  4. Verify laser receiver response
  5. Begin screeding

The system includes live calibration features that allow for adjustments during operation. Somero provides on-site training with machine purchase to ensure operators understand proper setup procedures.

What are the main limitations of the S-840 compared to larger models? +

Additional Information
While highly capable, the 2008 Somero S-840 Laser Screed has some limitations:

  • Screed width: Maximum 8-foot width means more passes on wide pours compared to larger models
  • Production rate: 5,000 sq ft/hr is excellent for its class but slower than boom screeds
  • Engine power: 20.5 HP is adequate for most applications but may struggle with very stiff concrete or thick lifts
  • Best for ground-level: While it can handle some elevated work, it’s optimized for slab-on-grade applications

The 2008 Somero S-840 Laser Screed is specifically designed for contractors who need laser screed accuracy and efficiency but work primarily on projects where larger equipment (like the S-22E or S-940) would be overkill or unable to access the site.
