-
If the service indicator is red, replace the air filter as described in Replacing the Filter.
-
Replacing the Filter
Important: To prevent engine damage, always operate the engine with the air filter and cover installed.
-
Gently slide the filter out of the air-cleaner body (Figure 41).
Note: Avoid knocking the filter into the side of the body.
Important: Do not attempt to clean the filter.
-
Inspect the new filter for tears, an oily film, or damage to the rubber seal. Look into the filter while shining a bright light on the outside of the filter; holes in the filter appear as bright spots.
If the filter is damaged, do not use it.
-
Carefully install the filter (Figure 41).
Note: Ensure that the filter is fully seated by pushing on the outer rim of the filter while installing it.
Important: Do not press on the soft inside area of the filter.

Use only 1 of the following fluids in the hydraulic system:
-
Toro Premium Transmission/Hydraulic Tractor Fluid (refer to your Authorized Service Dealer for more information)
-
Toro Premium All Season Hydraulic Fluid (refer to your Authorized Service Dealer for more information)
-
If either of the above Toro fluids are not available, you may use another Universal Tractor Hydraulic Fluid (UTHF), but they must be only conventional, petroleum-based products. The specifications must fall within the listed range for all the following material properties and the fluid should meet the listed industry standards. Check with your hydraulic fluid supplier to determine if the fluid meets these specifications.
Note: Toro will not assume responsibility for damage caused by improper substitutions, so use only products from reputable manufacturers who will stand behind their recommendations.
