MAINTENANCE
HYDRAULIC OIL, FILTERS, AND COMPONENTS
Filters and Oil - Change the return filter tank and suction filters after the first 100 hours of operation.
Change the filters again at 500 hours or every 12 months. Change the oil after the first 400 hours. After
that, continue to change the oil every 800 hours or 12 months. Hydraulic oil to be used is, Universal
Tractor Hydraulic. Speed Increaser uses SAE 80w 90 wt. gear oil and the spindle uses "000" Grease
Alamo #00765444, Mobil "000" EP023, or equivalent. Use the above procedures as part of a good filter
maintenance program.
Keep all hoses and adapters tight. Repair any leaks immediately. Do not overtighten hose end fittings.
Tighten to specifications only. (Figures Mnt-B-0004)
To check the grease level in the spindle, tilt the head of the unit on its side (vertical) until the spindle
housing is level. Remove the filler plug and the check plug. At this point the oil should be flush with the
bottom of the check plug hole. (Figures Mnt-B-0034)
Check the hydraulic oil level daily. Use Chevron 1000 THF or an equivalent.
NOTE: Your ambient temperature and operating conditions may require a different viscosity oil. Please
consult the oil manufacturer for proper specifications.
