The NSS Charger 2717 DB 6402731 is a 27-inch wheel-drive battery burnisher with a 330AGM battery system, onboard charger, 1700 RPM pad speed, 80 pounds of pad pressure, twist-grip propulsion, and integrated Vac-Trac dust control.

Features:

• 330AGM Battery Configuration – Provides a sealed, lower-maintenance battery setup for cordless commercial burnishing.

• Onboard Charger (OBC) – Keeps the charging system built into the machine for easier day-to-day charging without a separate external charger.

• Wheel-Drive DB Design – Uses a dedicated drive motor to propel the machine, reducing operator effort compared with the pad-assisted AB version.

• Twist-Grip Throttle Control – Gives the operator convenient control of powered movement for easier operation across large floor areas.

• 27-Inch Working Width – Covers a wide path with each pass for productive maintenance of expansive facilities.

• 1700 RPM Pad Speed – Provides high-speed burnishing performance for restoring gloss to compatible floor finishes.

• 80 lb. Pad Pressure – Combines substantial floor pressure with high rotational speed for effective polishing.

• Vac-Trac Dust Control System – Captures floor-finish powder generated during burnishing directly at the pad-motor shroud.

• Suitable for Concrete Polishing – Powerful motor performance makes the Charger 2717 suitable for use with compatible Twister diamond pads.

• Sealed AGM Battery Design – Eliminates routine battery watering and reduces battery-maintenance requirements.

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

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

• Wide-Area Productivity – The 27-inch platform reduces the number of passes needed across large open floor areas.

• Lower Routine Maintenance Requirements – Electric operation reduces many of the service demands associated with propane burnishers.

• Designed for Large Facilities – Well suited for schools, hospitals, retail environments, warehouses, airports, and other expansive finished-floor areas.

The NSS Charger 2717 DB 27-Inch Walk-Behind Auto Burnisher 6402731 combines the productive wheel-drive Charger 2717 platform with a 330AGM battery system and onboard charger.

Unlike the Charger 2717 AB, which uses an angled pad motor to help pull the machine forward, the 2717 DB uses a dedicated drive motor controlled through a twist-grip throttle. This reduces the amount of physical pushing required from the operator and can improve productivity during longer burnishing shifts.

330AGM Battery System

Model 6402731 is equipped with a 330AGM battery configuration.

AGM batteries are sealed and require less routine maintenance than traditional flooded lead-acid batteries.

Benefits include:

• No routine battery watering

• Sealed battery construction

• Reduced maintenance requirements

• Clean cordless operation

Actual operating time will vary based on floor condition, pad type, battery condition, burnishing load, operator technique, and facility layout.

Onboard Charger

This configuration includes an onboard charger.

Keeping the charger built into the burnisher simplifies charging by eliminating the need to store and connect a separate external charging unit.

This can be especially convenient in facilities where the machine is frequently moved between work and storage areas.

Wheel-Drive DB System

The Charger 2717 DB uses a dedicated powered wheel-drive system.

A separate drive motor moves the machine rather than relying on the rotating pad for forward assistance.

This can provide:

• Reduced operator fatigue

• More controlled movement

• Easier operation across large areas

• Improved productivity during extended shifts

Twist-Grip Throttle

The powered drive system is controlled with a twist-grip throttle.

This gives the operator intuitive control over machine movement while walking behind the burnisher.

27-Inch Working Width

The Charger 2717 provides a 27-inch / 69 cm working width.

The wider pad helps improve productivity by reducing the number of passes required across large open areas.

1700 RPM Burnishing Speed

The burnishing pad operates at approximately 1700 RPM.

This high-speed rotation is designed to restore gloss and appearance to compatible finished hard floors after scrubbing and routine maintenance.

80 lb. Pad Pressure

The Charger 2717 applies approximately 80 pounds of pad pressure.

The combination of substantial floor pressure and high pad speed helps efficiently restore floor-finish luster.

Vac-Trac Dust Control System

High-speed burnishing can generate fine floor-finish powder.

The Charger 2717 incorporates NSS’ Vac-Trac Dust Control System into the pad-motor shroud to collect dust as it is produced.

This helps reduce loose powder left behind after floor maintenance.

Concrete Polishing Capability

NSS identifies the Charger 2717 as suitable for concrete polishing with compatible Twister diamond pads.

This expands the machine beyond conventional finished-floor burnishing for facilities maintaining polished-concrete surfaces.

Battery-Electric Operation

The Charger 2717 DB uses battery-electric power rather than propane.

This eliminates the need for:

• Propane fuel purchases

• Fuel-cylinder storage and handling

• Engine oil changes

• Combustion-engine maintenance

• Indoor combustion exhaust during operation

68 dB(A) Sound Level

The Charger 2717 operates at approximately 68 dB(A).

Its relatively quiet electric operation can be useful in facilities where floor maintenance may take place during occupied or extended operating hours.

Professional Applications

The NSS Charger 2717 DB is well suited for:

• Schools and universities

• Hospitals and healthcare facilities

• Retail stores

• Grocery stores

• Warehouses

• Airports

• Convention facilities

• Office buildings

• Government facilities

• Commercial cleaning contractors

• Finished VCT floors

• Polished concrete with compatible Twister diamond pads
