Replacing the Fuel Filter

An in-line filter is incorporated into the fuel line between
the fuel tank and carburetor (Fig. 40). 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. 40) on the carburetor side of filter and remove the
fuel line from the filter.

Changing the Hydraulic Oil and
Filter
Normally, change the hydraulic oil and filter after every
2000 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.
1. Remove the drain plug from the reservoir (Fig. 41) and
let hydraulic oil flow into a drain pan. Reinstall and
tighten the plug when hydraulic oil stops draining.

2. Clean the area around the filter mounting area (Fig. 42).
Place a drain pan under the filter and remove the filter.

3. Fill the replacement filter with Mobil DTE 15M
hydraulic fluid. Lubricate the sealing gasket, and hand
turn the filter until the gasket contacts the filter head.
Tighten the filter 3/4 turn further. The filter should now
be sealed.
