Need help?Do you have a question about the Nilfisk-Advance 56390900 and is the answer not in the manual?
The Adgressor, Adgressor AXP, Adgressor EcoFlex, BR 850S, BR 1050S, BR 850S EDS, BR 1050S EDS, BR 850S EcoFlex, and BR 1050S EcoFlex are commercial rider scrubbers designed for efficient floor cleaning. These machines are available in various models, including Advance models (e.g., 56390900, 56390904, 56390902, 56390906, 56390908, 56390912, 56390910, 56390914, 56390903, 56390901, 56390907, 56390905, 56390911, 56390909, 56390915, 56390913, 56381000, 56381002, 56381004, 56381006, 56381001, 56381003, 56381005, 56381007) and Nilfisk models (e.g., 56390916, 56390919, 56390921, 56390923, 56390924, 56390922, 56390920, 56390918, 56381008, 56381010, 56381009, 56381011).
The Adgressor rider scrubber is designed for single-pass scrubbing operations, with controls optimized for one-touch operation. The machine features a scrub system that automatically raises and lowers the scrub deck, controls solution flow, and manages vacuum operation. Operators can select different scrub pressure settings (light, heavy, or adjustable) to vary the scrubbing effort. The machine also includes a vacuum/recovery system to collect wastewater, preventing overfilling with a shutoff float and displaying a "FULL" indicator when the recovery tank is full.
For enhanced cleaning, some models are equipped with automatic detergent mixing systems (AXP and EcoFlex). These systems allow the operator to use only water in the solution tank and detergent in a separate tank, with the machine automatically mixing the detergent to match the operator's request. The EcoFlex system offers different cleaning approaches, such as "light soil" (normal) and "heavy soil" (override), which temporarily increase solution flow and detergent concentration.
The machine's drive system utilizes an 1100-watt 1.5 HP (permanent magnet) 36V motor/gear transmission, regulated by a Curtis model 1237 PMC solid-state speed controller. This controller manages variable speed for both forward and reverse movement, with speed limits for transport and scrub modes. An operator's foot pedal with a 5.75K Ohm potentiometer inputs desired speed and directional demands to the controller.
The control panel is designed for intuitive operation, with indicators for scrub system status, battery condition, scrub pressure, vacuum system, and solution system. The machine features a key switch for main power, a speed select switch to adjust transport speed, a horn switch (also functions as a backup alarm), and switches for vacuum and solution control. The scrub system can be programmed for different operational modes, including pressure increase/decrease, fixed pressure, and light/heavy scrub.
The squeegee system automatically lifts when the machine operates in reverse to prevent damage and excessive wear. The vacuum system includes a shutoff float to prevent overfilling of the recovery tank. The machine also has an emergency stop switch for safety.
Regular maintenance is crucial for prolonging the machine's life and ensuring optimal performance. Key maintenance tasks include:
The machine's main control board includes diagnostic capabilities, displaying error codes on the hourmeter/status display to assist with troubleshooting. The Curtis speed controller also provides fault codes. The drive pedal potentiometer is pre-adjusted at the factory and typically does not require adjustment.
Battery maintenance includes maintaining proper electrolyte levels (using distilled water), keeping batteries charged after each use (or monthly if stored), and keeping battery tops clean. The machine features a low voltage cutout feature to prevent over-discharging of batteries, with adjustable thresholds for standard and maintenance-free batteries.
