Engine Maintenance
Air Cleaner Maintenance
• Check the air cleaner body for damage which could
possibly cause an air leak. Replace a damaged air
cleaner body. Check the whole clean air intake
system for leaks, damage, or loose hose clamps.
• Service the air cleaner filter when the air cleaner
indicator (Figure 43) shows red or every 400
hours (more frequently in extremely dusty or dirty
conditions). Do not over service the air filter.

Servicing the Air Cleaner
Service Interval: Every 400 hours
1. Pull the latch outward and rotate the air cleaner
cover counter-clockwise (Figure 43).
2. Remove the cover from the air cleaner body
(Figure 43).
3. Before removing the filter, use low pressure
air (40 psi, clean and dry) to help remove large
accumulations of debris packed between outside of
primary filter and the canister.
This cleaning process prevents debris from migrating
into the intake when the primary filter is removed.

Important: Avoid using high pressure air which
could force dirt through the filter into the intake
tract.
4. Remove and replace the primary filter (Figure 43).
Important: Do not clean the used element to
avoid damage to the filter media.
5. Inspect the new filter for shipping damage, checking
the sealing end of the filter and the body.
Important: Do not use a damaged element.
6. Ensure that the foam gasket is in place in the cover
and that it is not torn or damaged (Figure 43). If it is
damaged, replace it.
7. Insert the new filter by applying pressure to the outer
rim of the element to seat it in the canister.
Important: Do not apply pressure to the flexible
center of the filter.
8. Clean the dirt ejection port located in the removable
cover, as follows:
A. Remove the rubber outlet valve from the cover
(Figure 43).
B. Clean the cavity.
C. Replace the outlet valve.
9. Install the cover orienting the rubber outlet valve in
a downward position—between approximately 5:00
to 7:00 when viewed from the end.
10. Reset the indicator (Figure 43) if showing red.
Servicing the Engine Oil
Checking the Engine Oil Level
Service Interval: Before each use or daily
The engine is shipped with oil in the crankcase; however,
the oil level must be checked before and after the
engine is first started. Check oil level before each day's
operation or each time machine is used.
The crankcase capacity is approximately 4 qt. (3.8 l)
with the filter. Use high-quality engine oil that meets
the following specifications:
• API Classification Level Required: CH-4, CI-4 or
higher.
• Preferred oil: SAE 15W-40 (above 0°F (-17°C)
• Alternate oil: SAE 10W-30 or 5W-30 (all
temperatures)
Note: Toro Premium Engine oil is available from your
distributor in either 15W-40 or 10W-30 viscosity. See the
parts catalog for part numbers.
