Engine Maintenance

Engine Safety

Shut off the engine before checking the oil or adding oil to
the crankcase.

Servicing the Air Cleaner

Service Interval: Every 400 hours
Check the air-cleaner body for damage that could cause an air
leak. Replace a damaged air cleaner. Check the whole intake
system for leaks, damage, or loose hose clamps.
Service the air-cleaner filter only when the service indicator
(Figure 26) requires it. Changing the air filter before it is
necessary only increases the chance of dirt entering the engine
when you remove the filter.
Important: Be sure that the cover is seated correctly
and seals with the air-cleaner body.
1. Release the latch securing the air-cleaner cover to the
air-cleaner body (Figure

indicator
2. Air-cleaner cover
2. Remove the cover from the air-cleaner body. Before
removing the filter, use clear and dry low-pressure air
(276 kPa or 40 psi) to help remove large accumulations
of debris packed between outside of the filter and
the canister. Avoid using high-pressure air, which
could force dirt through the filter into the intake
tract.
Note: This cleaning process prevents debris from
migrating into the intake when you remove the filter.
3. Remove and replace the filter.
Important: Do not clean the used element to
prevent damaging the filter media. Inspect the
26).
3. Air-cleaner-cover latch
new filter for shipping damage, checking the
sealing end of the filter and the body. Do not
use a damaged element. Insert the new filter by
applying pressure to the outer rim of the element
to seat it in the canister. Do not apply pressure to
the flexible center of the filter.
4. Clean the dirt-ejection port located in the removable
cover.
5. Remove the rubber outlet valve from the cover, clean
the cavity and replace the outlet valve.
6. Install the cover orienting the rubber outlet valve in
a downward position—approximately between the 5
o'clock to 7 o'clock positions when viewed from the
end.
7. Secure the latch.

Checking the Engine-Oil Level

Service Interval: Before each use or daily
The engine is shipped with oil in the crankcase; however,
check the oil level before and after you start the engine for
the first time.
The crankcase capacity is approximately 5.2 L (5.5 US qt)
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)
•
Alternate oil: SAE 10W-30 or 5W-30 (all temperatures)
Toro Premium Engine Oil is available from your distributor
in either 15W-40 or 10W-30 viscosity.
