Cleaning The Radiator And Screen; Changing The Engine Oil And Filter; Changing The Hydraulic System Fluid And Filter - Toro 03422 Operator's Manual

4. Washing Method
A. Prepare a solution of filter cleaner and water and
soak the filter element about 15 minutes. Refer to
the directions on the filter cleaner carton for
complete information.
B. After soaking the filter for 15 minutes, rinse it with
clear water. Maximum water pressure must not
exceed 40 psi to prevent damage to the filter
element. Rinse the filter from the clean side to the
dirty side.
C. Dry the filter element using warm, flowing air
(160 F max.), or allow the element to air-dry. Do
not use a light bulb to dry the filter element because
damage could result.
5. Compressed Air Method
A. Blow the compressed air from the inside to the
outside of a dry filter element. Do not exceed
100 psi to prevent damage to the element.
B. Keep the air hose nozzle at least 2 in. (51 mm) from
the filter and move the nozzle up and down while
rotating the filter element. Inspect the filter for holes
and tears by looking through the filter toward a
bright light.
6. Inspect the new filter for shipping damage. Check the
sealing end of the filter. Do not install a damaged filter.
7. Insert the new filter properly into the air cleaner body.
Make sure that the filter is sealed properly by applying
pressure to the outer rim of the filter when installing.
Do not press on the flexible center of the filter.
8. Install the cover and secure the latches. Make sure that
the cover is positioned with the TOP side up.
Cleaning the Radiator and
Screen
To prevent the system from overheating, the radiator
screen, radiator, and oil cooler must be kept clean. Check
the screen, radiator, and oil cooler daily and, if necessary,
clean any debris off of these parts. Clean these components
more frequently in dusty dirty conditions.
1. Remove the radiator screen (Fig. 49).
2. Working from the fan side of the radiator, either spray
the radiator with a hose or blow it with compressed air.

3. Thoroughly clean the oil cooler (Fig. 49) and remove
any other debris that may have collected around the
components.
4. Clean the screen and install it.
Changing the Engine Oil and
Filter
Change the oil and filter initially after the first 20 hours of
operation. Thereafter, change the oil every 50 hours and the
filter every 100 hours.
1. Locate the engine oil drain plug on the bottom of the oil
pan. Remove the drain plug and let the oil flow into the
drain pan. When the oil stops, install the drain plug.
2. Locate the engine filter on the front of the engine.
Remove the oil filter. Apply a light coat of clean oil to
the new filter seal before screwing it on. Do not
over-tighten.
3. Add oil to the crankcase; refer to Checking the
Crankcase Oil, page 21.
Changing the Hydraulic
System Fluid and Filter
The hydraulic system filter must be changed initially, after
the first five hours of operation, and thereafter every 200
hours of operation or yearly, whichever comes first. Use a
genuine Toro oil filter for replacement. The hydraulic fluid
must be changed every 400 hours of operation or yearly,
whichever comes first.
