MAINTENANCE

HYDRAULIC OIL, FILTERS, & COMPONENTS

Filters and Oil - Change the return filter in the tank after the first 200 hours of operation. Change the filters again at 800 hours; then, change the oil and filters at 1600 hours. After that, continue to change the filter every 800 hours and the oil every 1600 hours. Hydraulic oil to be Chevron 1000 THF or equivalent. Use SAE 90 wt. in Speed Increaser. Use the above procedures as part of a good filter maintenance program.

Note: Your ambient temperature and operating conditions may require a different viscosity oil. Please consult the oil manufacturer for proper specifications.

RESERVOIR

The reservoir stores hydraulic system oil. The breather cap which is mounted on top of the reservoir prevents an extreme pressure buildup or vacuum from occurring in the tank as oil level changes. There is also an oil filler cap which is used to fill the reservoir with oil. To help prevent dirt from entering the tank, clean the top of the reservoir before removing the cap. THE BREATHER CAP HOLDS APPROX 11 PSI PRESSURE IN TANK.

REMOVE FILLER CAP SLOWLY

The oil level sight glass is located on the back of the reservoir. The oil level should be even with the sight glass and checked with the cutter unit in the transport position. The oil temperature should not exceed 180 degree F. The oil return hoses are connected to the hydraulic filter on top of the reservoir. Oil is returned from cutter unit cooling tubes and filtered before entering the hydraulic reservoir. Oil returning from the control circuit also enters the reservoir through the filter.

PROPER OIL LEVEL

Maintain the oil level within the sight gauge located on the side of the reservoir. Never fill the tank above the sight gauge level. A space is maintained above the sight gauge to allow for the expansion of the oil. The tank maintains pressure after the mower has been run. Stand off to one side when removing the breather cap element to prevent possible injury. To relieve pressure, remove the breather cap element and depress the spring loaded pressure valve to release any excess air. Fill with Universal Tractor Hydraulic Oil.

Alamo is a prominent historical site located in San Antonio, Texas, that embodies a rich tapestry of events from the early 19th century. Originally established as a Spanish mission known as Mission San Antonio de Padua in the early 1700s, the Alamo has become a symbol of resistance and valor in the face of overwhelming odds.

The site features the famous chapel, known for its adjoining long barracks and a simple yet iconic façade that captures the spirit of the era. Despite suffering extensive damage over the years, the Alamo has been meticulously preserved and continues to serve as a key historical monument.

Technologically, the Alamo has undergone various renovations and restorations to maintain its integrity against the elements and modern advancements. Preservation efforts utilize contemporary methods such as laser scanning and 3D rendering to create accurate models for restoration. These high-tech methodologies ensure that any repairs or alterations respect the original structure while improving its resilience.

One of the remarkable characteristics of the Alamo is its role as a rallying point for Texan independence. The phrase "Remember the Alamo!" has transcended its historical context, serving as a powerful battle cry not only for Texas but also as a symbol of determination and sacrifice in various struggles for freedom worldwide.
