Replacing The Fuel Filter; Changing The Hydraulic Oil And Filter - Toro Greensmaster
3150 Operator's Manual

Replacing the Fuel Filter

An in-line filter is incorporated into the fuel line between
the fuel tank and carburetor (Fig. 48). Replace the filter
every 800 hours or sooner if the fuel flow is restricted. Be
sure the arrow on the filter is pointing away from the fuel
tank.
Danger
In certain conditions, gasoline is extremely
flammable and highly explosive. A fire or
explosion from gasoline can burn you and others
and can damage property.
• Drain gasoline from the fuel tank when the
engine is cold. Do this outdoors in an open area.
Wipe up any gasoline that spills.
• Never smoke when draining gasoline, and stay
away from an open flame or where a spark may
ignite the gasoline fumes.
1. Close the fuel shut off valve, loosen the hose clamp
(Fig. 48) on the carburetor side of filter and remove the
fuel line from the filter.

hose clamp, and remove the filter (Fig. 48).
3. Install the new filter with the arrow on the filter body
pointing away from the fuel tank.

Changing the Hydraulic Oil and
Filter
Change the hydraulic oil after every 800 operating hours.
If the oil becomes contaminated, contact your local Toro
distributor because the system must be flushed.
Contaminated oil looks milky or black when compared to
clean oil.
Change the filter:
• After the first 50 operating hours
• After every 800 operating hours
1. Clean the area around the filter mounting area (Fig. 49).
Place a drain pan under the filter and remove the filter.
Note: If the oil is not going to be drained, disconnect and
plug the hydraulic line going to the filter.
2. Fill the replacement filter with the appropriate hydraulic
fluid, lubricate the sealing gasket, and hand turn it until
the gasket contacts the filter head. Then tighten 3/4 turn
further.
3. Fill the hydraulic reservoir and small auxiliary tank
with approximately 8–1/2 gallons (32 l) of hydraulic
oil; refer to Servicing the Hydraulic System, page 17.
4. Start the machine and run it at idle for 3 to 5 minutes to
circulate the fluid and remove any air trapped in the
system. Stop the machine and recheck the fluid level.
5. Dispose of the oil properly.
Note: If the leak detector alarm sounds, turn the key off
and wait a few minutes for the oil level to equalize in the
tanks. Recheck the fluid level and add oil, if required.
