1. Close the fuel shut-off valve, loosen the hose
clamp on the carburetor side of the filter and
remove the fuel line from the filter.
2. Place a drain pan under the filter, loosen the
remaining hose clamp and remove the filter.
3. Install the new filter with the arrow on the filter

Changing the Hydraulic Oil and
Filter
Normally, change the hydraulic oil and filter after
every 2,000 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 with clean
oil.
1. Remove the drain plug from the reservoir and let
the hydraulic oil flow into a drain pan. Install
and tighten the plug after the hydraulic oil stops
draining.

3. Fill the replacement filter with Mobil DTE 15M
hydraulic fluid, lubricate the sealing gasket and
hand turn until the gasket contacts the filter head.
Then tighten 3/4 turn further. The filter should
now be sealed.
4. Fill the large hydraulic tank and small auxiliary
tank with approximately 32l of hydraulic oil.
Refer to Check the Hydraulic System.
5. 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.
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.
6. Dispose of oil properly.
Checking Hydraulic Hoses and
Lines
Check hydraulic lines and hoses daily for leaks,
kinked lines, loose mounting supports, wear, loose
fittings, weather deterioration and chemical
deterioration. Make all necessary repairs before
operating.
