Change Hydraulic System Fluid and Filter
The hydraulic system filter must be changed initially af- ter the first 8 hours of operation. Thereafter, it must be changed every 400 hours of operation or yearly, which- ever comes first. Use a genuine Toro oil filter for replace- ment. The hydraulic oil must be changed every 400 hours of operation or yearly, whichever comes first.
1.Park machine on a level surface and turn the engine
off.
2.On the SP 2020/3020, pivot seat up. On the SP 5020, remove three cap screws securing the right side panel to the machine and remove panel.
3.On the SP 2020/3020, disconnect tube from the bot- tom fitting of the hydraulic tank. Let oil flow into a drain pan. Reinstall and tighten tube connection when oil stops draining.
4.On the SP 5020, place a funnel under the tank drain plug to direct oil into a drain pan. Remove drain plug and allow oil to drain into pan. Reinstall and tighten drain plug when the oil stops draining (Fig. 22).
5.Clean area around the hydraulic oil filter. Remove filter from the filter head. Allow oil to flow into a drain pan. Dispose of the oil filter properly (Fig 23 or 24).
6.Apply a film of clean hydraulic oil on the filter gasket. Install filter by hand until gasket contacts filter head, then tighten filter an additional
7.Fill tank to the proper level (see Check Hydraulic System Fluid).
8.Make sure traction pedal and lift lever are in the neutral position. Start engine. Run engine at lowest possible RPM to purge the system of air.
9.Run engine until the lift cylinder can be extended and retracted and wheel motion in the forward and re- verse direction is achieved.
10.Stop engine and check oil level in the tank. Add oil if necessary.
11.Check all hydraulic connections for leaks.
12.On the SP 2020/3020, pivot seat down. On the SP 5020, install right side panel and secure with three cap screws.
13.Dispose of oil properly.
