The NSS Charger 2717 DB 6402733 is a 27-inch wheel-drive battery burnisher with a 350AH 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:

• 350AH Battery Configuration – Provides a high-capacity battery setup for extended cordless commercial burnishing.

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

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

• 120V Charging Configuration – Designed for charging from compatible standard commercial electrical service.

• Key-Controlled Configuration – Adds keyed access to help control who can operate the machine.

• 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 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.

• 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 6402733 combines the productive wheel-drive Charger 2717 platform with a 350AH battery configuration for demanding commercial floor-care programs.

The DB model uses a dedicated drive motor controlled by a twist-grip throttle, helping reduce the physical effort required from the operator during long burnishing shifts.

This configuration also includes 120V charging and keyed operation, while retaining the Charger 2717 family’s 27-inch working width, 1700 RPM pad speed, 80 pounds of pad pressure, and Vac-Trac dust control.

350AH Battery Configuration

Model 6402733 is equipped with a 350AH battery configuration.

The larger battery capacity is designed to support extended cordless operation across large commercial floor areas.

Actual runtime will vary depending on:

• Battery condition

• Floor condition

• Pad type

• Burnishing load

• Operator technique

• Facility layout

Wheel-Drive DB System

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

Unlike the AB model, which relies on an angled pad motor to help pull the machine forward, the DB uses a separate drive motor for propulsion.

This can provide:

• Reduced operator fatigue

• More controlled machine movement

• Easier operation over large areas

• Improved productivity during extended shifts

Twist-Grip Throttle

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

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

Key-Controlled Operation

This configuration includes a key-controlled setup.

Keyed operation can help facilities manage equipment access and reduce unauthorized use.

120V Charging Configuration

The battery system is configured for 120V charging.

This makes it practical for facilities using compatible standard North American commercial electrical service.

27-Inch Working Width

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

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

1700 RPM Burnishing Speed

The 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 maintenance.

80 lb. Pad Pressure

The Charger 2717 applies approximately 80 pounds of pad pressure.

The combination of substantial 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 debris during operation.

This helps reduce loose dust left behind after polishing.

Concrete Polishing Capability

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

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

Battery-Electric Operation

The Charger 2717 DB uses battery-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
