Change Hydraulic Fluid - Toro Reelmaster 3100-D Service Manual

Change Hydraulic Fluid

Change hydraulic fluid after every 400 operating hours,
under normal conditions. If fluid becomes contami-
nated, the system must be flushed. Contaminated fluid
looks milky or black when compared to clean oil.
1. Turn engine off and raise hood.
2. Disconnect hydraulic hose from filter head or remove
hydraulic filter and let hydraulic fluid flow into drain pan.
When hydraulic fluid stops draining, connect the hy-
draulic hose or install new hydraulic filter.
3. Fill hydraulic tank with approximately 3.5 gallons
(13.2 liters) of hydraulic fluid. Refer to Check Hydraulic
Fluid.
IMPORTANT: Use only recommended hydraulic
fluids to fill hydraulic tank. Other fluids could cause
system damage.
4. Install hydraulic tank cap. Start engine and use all hy-
draulic controls to distribute hydraulic fluid throughout
the system. Also check for leaks. Then stop the engine.
5. Check level of fluid and add enough to raise level to
FULL mark on dipstick. DO NOT OVER FILL.
