Lubrication and Maintenance Guidelines

Use SAE 90 gear lubricant for all moving parts. Lubricate rear squeegee caster pivot every 50 hours. Follow manufacturer’s intervals, inspect for dust, and replace grease (01433‑1) as needed and check seals

Lubricant Types and Specifications (e.g., SAE 90 gear lubricant)

The Tennant T12 requires a specific lubricant to maintain optimal performance. The recommended fluid is a distilled, SAE 90 weight gear lubricant, identified in the parts list as part number 01433‑1. This grease is formulated to provide excellent film strength at high temperatures while resisting oxidation and corrosion. It contains a high‑viscosity base oil and a blend of synthetic additives that enhance wear protection for the machine’s bearings, gears, and pivot points. The SAE 90 rating indicates a viscosity index that ensures consistent lubrication under a wide range of operating temperatures, from cold startup to full load. For the rear squeegee caster pivot, the lubricant should be applied directly to the pivot pin and surrounding housing after every 50 hours of operation, or more frequently if the machine is used in extremely dusty or abrasive environments. The grease should be stored in a cool, dry place, sealed to prevent contamination, and inspected for signs of degradation before each application. When applying, use a small brush or a dedicated grease gun to avoid over‑lubrication, which can attract dust and reduce performance. Always follow the manufacturer’s safety guidelines and ensure the machine is powered off before handling any lubricants. By adhering to these specifications, you guarantee extended component life and reliable operation of the Tennant T12. Use only the listed SAE 90 grease to maintain optimal bearing life and prevent premature wear. Now

Maintenance Intervals and Conditions

The Tennant T12’s maintenance schedule is defined by operating hours and environmental factors. Routine checks should occur every 50 hours of use, with a comprehensive inspection every 200 hours. During each 50‑hour interval, lubricate the rear squeegee caster pivot, inspect brush wear, and verify hydraulic fluid levels. The 200‑hour review requires a full system check: replace worn brushes, clean the data plate, inspect the steering chain (T12XP only), and confirm all safety guards are intact. In dusty or high‑temperature environments, reduce the interval to every 25 hours, and perform an additional oil change. If the machine operates continuously for more than 8 hours per day, schedule a daily pre‑start check to confirm key components are secure.
