The NSS Charger 2717 DB 6402752 is a 27-inch wheel-drive battery burnisher with a 160 lithium battery configuration, 1700 RPM pad speed, 80 pounds of pad pressure, twist-grip propulsion, and integrated Vac-Trac dust control for productive large-area floor maintenance.

Features:

• 160 Lithium Battery Configuration – This version uses a lithium battery system for cordless commercial burnishing.

• Wheel-Drive DB Design – The major upgrade over the pad-assisted AB model, using a dedicated drive motor to propel the machine and reduce operator effort.

• Twist-Grip Throttle Control – Provides intuitive control of the powered drive system for easier movement and improved productivity.

• 36VDC Machine System – Uses a 36-volt DC electrical platform for battery-powered operation.

• 120VAC Charging Configuration – Designed for charging from compatible 120V AC electrical service.

• 27-Inch Working Width – Covers a wide floor area with each pass for productive maintenance of large facilities.

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

• 80 lb. Pad Pressure – Combines substantial pad 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.

• 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 required 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 6402752 is designed for facilities that need the productivity of a wide-area walk-behind burnisher with powered wheel drive.

Unlike the Charger 2717 AB, which relies on the angled pad motor to help pull the machine forward, the 2717 DB uses a dedicated drive motor controlled by a twist-grip throttle. This reduces the physical effort required from the operator and can improve productivity during long burnishing shifts.

This configuration also features a 160 lithium battery system, 36VDC machine voltage, and 120VAC charging configuration.

Wheel-Drive DB System

The defining feature of the Charger 2717 DB is its powered wheel-drive system.

A dedicated drive motor propels the machine instead of relying on the pad to provide forward assistance.

This can provide several advantages:

• Reduced operator fatigue

• More controlled movement

• Easier operation across large areas

• Improved productivity

• Less physical pushing during extended shifts

Twist-Grip Throttle

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

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

160 Lithium Battery Configuration

Model 6402752 is equipped with a 160 lithium battery configuration.

Lithium battery technology provides cordless operation without the routine watering requirements associated with flooded lead-acid batteries.

Actual operating time will vary depending on:

• Battery condition

• Pad type

• Floor condition

• Burnishing load

• Operator technique

• Facility layout

36VDC Electrical System

The Charger 2717 DB operates on a 36VDC battery system.

The battery-electric platform provides cordless mobility throughout large facilities without requiring a power cord during burnishing.

120VAC Charging Configuration

This configuration is designed for charging from compatible 120VAC electrical service.

This makes it practical for facilities with standard North American electrical infrastructure.

27-Inch Working Width

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

The wide pad increases 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 the glossy appearance of compatible floor finishes after scrubbing and routine floor maintenance.

80 lb. Pad Pressure

The Charger 2717 applies approximately 80 pounds of pad pressure.

The combination of significant downward pressure and 1700 RPM pad speed helps efficiently restore floor-finish luster.

Vac-Trac Dust Control System

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

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

This helps reduce loose floor-finish powder left behind after burnishing.

Concrete Polishing Capability

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

This allows the same platform to be used for more than conventional floor-finish burnishing when properly equipped.

Battery-Electric Operation

The Charger 2717 DB uses electric power instead of 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 diamond pads
