The NSS eForce 6402778 is a 27-inch battery-powered rider burnisher with a CAL configuration, 390AH AGM batteries, patented joystick control, adjustable pad pressure, 1700 RPM burnishing speed, and integrated Vac-Trac dust control.

Features:

• CAL, 390AH AGM Configuration – This version combines NSS’ CAL-specific configuration with a sealed 390AH AGM battery system.

• 27-Inch Burnishing Width – Covers a wide path with each pass for efficient maintenance of large finished-floor areas.

• 1700 RPM Pad Speed – Delivers high-speed burnishing performance to restore gloss and appearance to compatible floor finishes.

• Adjustable 60, 75 or 90 lb. Pad Pressure – Lets the operator match pad pressure to floor condition, finish, and maintenance requirements.

• Patented Joystick Control – Replaces a conventional steering wheel and foot pedal with intuitive hand control.

• Natural Operator Position – Joystick operation allows the operator to remain in a comfortable seated position during extended burnishing shifts.

• Flip-Up Pad Driver – Allows pad changes from a standing position for easier daily maintenance.

• Vac-Trac Dust Control System – Captures 99.5% of floor-finish powder and dust generated during burnishing.

• Integrated Dust Collection – Dust control is built directly into the pad-motor shroud for cleaner operation.

• 68 dB(A) Sound Level – Supports relatively quiet operation in commercial and institutional facilities.

• Sealed AGM Batteries – AGM construction eliminates routine battery watering and reduces battery-maintenance requirements.

• Electric Operation – Eliminates propane fuel handling, engine oil changes, and combustion-engine maintenance.

• Lower Routine Maintenance Requirements – Battery-electric construction reduces many of the service tasks associated with propane burnishers.

• Consistent High-Speed Performance – Combines pad speed and controlled pressure to efficiently restore floor-finish luster.

• Designed for Large Facilities – Well suited for schools, healthcare facilities, retail spaces, warehouses, and other expansive finished-floor environments.

The NSS eForce Rider Burnisher CAL, 390AH AGM 6402778 is designed for facilities that need productive ride-on burnishing with a sealed, lower-maintenance AGM battery configuration.

It retains the core eForce platform with a 27-inch pad, 1700 RPM speed, three selectable pad-pressure settings, patented joystick steering, flip-up pad driver, and Vac-Trac dust collection system.

CAL, 390AH AGM Configuration

Model 6402778 is identified as the CAL, 390AH AGM configuration.

The sealed AGM battery system is designed to reduce routine battery maintenance compared with traditional flooded lead-acid batteries.

Benefits of AGM construction include:

• No routine battery watering

• Sealed design

• Reduced maintenance requirements

• Clean battery-electric operation

Patented Joystick Control

One of the eForce’s defining features is NSS’ patented joystick steering system.

Instead of using a conventional steering wheel and foot pedal, the operator controls the machine with the joystick while remaining in a more natural seated position.

This can help reduce repetitive steering movement during extended burnishing shifts.

1700 RPM Burnishing Speed

The eForce operates at approximately 1700 RPM.

This high-speed pad rotation is designed to restore shine and appearance to compatible finished hard floors during routine maintenance.

Adjustable Pad Pressure

The operator can select from three pad-pressure settings:

• 60 lbs.

• 75 lbs.

• 90 lbs.

Adjustable pressure provides flexibility for different floor conditions, pads, finishes, and maintenance requirements.

27-Inch Burnishing Path

The 27-inch pad size provides broad floor coverage with each pass.

Combined with the ride-on platform, this makes the eForce particularly useful for large facilities where walk-behind burnishing would require more operator travel.

Vac-Trac Dust Control System

Burnishing can create fine powder and floor-finish dust as the pad works across the surface.

The eForce incorporates NSS’ Vac-Trac Dust Control System directly into the pad-motor shroud.

NSS states that the system captures approximately 99.5% of the floor-finish powder and dust generated during burnishing.

This helps reduce loose dust left behind after floor maintenance.

Flip-Up Pad Driver

The pad driver flips upward for easier pad access.

This allows operators to change pads from a standing position rather than reaching underneath the machine.

Electric Burnishing

The eForce uses battery-electric power instead of propane.

This eliminates the need for:

• Propane fuel purchases

• Engine oil changes

• Combustion-engine maintenance

• Fuel-cylinder handling

• Indoor combustion exhaust during operation

The simpler electric platform can also reduce routine maintenance requirements.

68 dB(A) Sound Level

The eForce operates at approximately 68 dB(A).

Its relatively quiet electric operation can be useful in facilities where floor maintenance may occur during occupied hours.

Professional Applications

The NSS eForce is well suited for:

• Schools and universities

• Hospitals and healthcare facilities

• Retail stores

• Grocery stores

• Airports

• Convention facilities

• Office buildings

• Warehouses

• Government buildings

• Large commercial facilities
