All parts listed.!!
Battery and Wiring Harness
The Tennant T300E utilizes a 12‑V sealed lead‑acid battery rated at 100 Ah, positioned beneath the operator’s seat for optimal weight distribution. The battery is secured in a reinforced plastic enclosure with a removable cover to facilitate quick access during routine checks. The manual specifies a maximum charging voltage of 14.4 V and a recommended charging current of 10 A, ensuring longevity while preventing over‑charging. A built‑in temperature sensor monitors battery temperature, triggering an alarm if it exceeds 45 °C to safeguard against thermal runaway.
The wiring harness is a modular, double‑shielded cable assembly that connects the battery, alternator, control panel, and all peripheral devices. It features 16 conductors, each rated for 30 A, and is routed through a protective conduit that shields it from abrasion and chemical exposure. The harness includes a main fuse block (part number 4‑B‑FUSE‑01) rated at 40 A, a ground bus bar, and a series of terminal blocks for easy replacement. The manual lists the exact wire gauge (AWG 10) and color coding scheme: red for positive, black for negative, green for ground, and yellow for signal lines.
For troubleshooting, the manual advises using a multimeter to check continuity across battery terminals. If a drop exceeds 0.5 V, inspect cables for corrosion or loose connections. The wiring diagram (Figure 12) shows routing of each conductor and connection points to the engine control unit and hydraulic pump. The diagram also notes the battery disconnect switch (part 5‑B‑DIS‑02), allowing isolation without disconnecting the harness.
Accessory and Optional Equipment
The Tennant T300E offers optional attachments such as a 3‑pass scrubber, a high‑capacity water tank, and a UV‑sterilizer.Each accessory has a unique part number and can be installed via the standard mounting brackets. Consult the manual for torque specs and wiring diagrams.
Cleaning attachments and consumables are critical to maintaining the Tennant T300E’s performance. The manual lists several brush assemblies, pad types, and chemical cartridges, each identified by a unique part number and recommended replacement schedule. The standard 3‑pass brush set (PN 300‑B01) features a 12‑inch diameter, nylon bristles with a 30‑degree angle for deep‑scrub action. For high‑traffic commercial floors, the heavy‑duty brush (PN 300‑B02) offers reinforced bristles and a 15‑inch width, designed to handle abrasive debris without excessive wear. Pad options include the 10‑inch microfiber pad (PN 300‑P01) for gentle cleaning, and the 12‑inch rubber pad (PN 300‑P02) for heavy‑dust removal. Each pad is rated for a 3‑month cycle before replacement, with visual indicators on the attachment housing to signal wear. Chemical consumables are listed under the “Cleaning Solution Cartridges” section. The standard 2‑gal cartridge (PN 300‑C01) contains a balanced detergent solution, compatible with the T300E’s built‑in dispenser. For disinfecting, the 1‑gal disinfectant cartridge (PN 300‑C02) contains a 0.5% bleach solution, which should be replaced after 200 gallons of use to maintain efficacy. The manual also details the optional UV‑sterilizer attachment (PN 300‑U01), which requires a separate power supply and a 1‑year service interval. All consumables are designed to fit the T300E’s modular system, allowing quick swaps without tools. Proper maintenance of these parts extends machine life and ensures consistent cleaning results across various floor types. All consumables are stored in the rear compartment, and the manual recommends inspecting them monthly to prevent clogging. The T300E’s user interface displays a warning when pad wear exceeds 80% of its life, prompting timely replacement. daily.
Parts Catalog and Identification
The T300E parts catalog lists each component with a unique part number, serial ID, and installation diagram. Components are grouped by system—engine, transmission, electrical, cleaning attachments. The manual includes a lookup table and barcode references for identification.
Serial Number and Part Numbering System
The Tennant T300E parts manual assigns a 12‑character serial number to each unit, printed on the chassis plate. The first four digits encode the production month and year (e.g., 2607 for July 2026), the next two identify the factory line, and the final six are a batch code. This format allows warranty verification without lookup.
Part numbers follow a structured scheme: “T300E‑B‑02‑A‑001”. “T300E” denotes the model, “B” the component group, “02” the sub‑category, “A” the material grade, and “001” the unique identifier. The manual’s lookup table links each number to part name, weight, torque specs, ensuring correct replacements.
Variants such as brush width or chemical‑resistant coatings use suffixes. For example, “T300E‑C‑05‑B‑002‑R” indicates a cleaning attachment (C), sub‑category 05 (brush), material grade B, variant 002, and coating R for resistant. The suffixes standardize across Tennant models, enabling technicians to identify compatible accessories. The barcode system streamlines inventory: each part number is printed on a QR code that can be scanned to pull up the full specification sheet, service history, and recall notices.
Serial and part numbers are integrated into the ECU firmware. During a diagnostic scan, the ECU reads the machine’s serial number and cross‑checks it against the part database in the cloud. If a component’s part number is flagged as obsolete or recalled, the ECU triggers an alert on the operator’s display. This integration ensures the T300E remains compliant with safety regulations and that replacement parts are sourced from authorized Tennant distributors. The manual’s tables and charts provide a comprehensive mapping between serial numbers, part numbers, and service procedures, making repairs accurate and maintaining optimal performance.
