Engine Maintenance

Engine Safety

•
Shut off the engine and remove the key before
checking the oil or adding oil to the crankcase.
•
Do not change the governor speed or overspeed
the engine.

Servicing the Air Cleaner

Service Interval: Every 200 hours (More frequently in
extreme dusty or dirty conditions)
Inspect the air cleaner and hoses periodically to
maintain maximum engine protection and to ensure
maximum service life. Check the air-cleaner body for
damage, which could cause an air leak. Replace a
damaged air-cleaner body.
Inspect and change the air-cleaner filter as described
in the following procedure:
1. Pull the latch outward and rotate the air-cleaner
cover counterclockwise.

2. Before removing the filter, use low-pressure air
(40 psi, clean and dry) to help remove large
accumulations of debris packed between the
outside of the primary filter and the canister.
Important:
Avoid using high-pressure air
which could force dirt through the filter
into the intake tract. This cleaning process
prevents debris from migrating into the
intake when you remove the primary filter.
3. Remove and replace the primary filter.

2. Filter
Note:
Cleaning of the used element is not
recommended due to the possibility of damage
to the filter media.
4. Inspect the new filter for shipping damage,
checking the sealing end of the filter and the
body.
Important:
Do not use a damaged filter.
5. Insert the new filter by applying pressure to the
outer rim of the element to seat it in the canister.
6. Clean the dirt ejection port located in the
removable cover. Remove the rubber outlet
valve from the cover, clean the cavity, and
replace the outlet valve.
7. Install the cover orienting the rubber, outlet valve
in a downward position, between approximately
5 o'clock to 7 o'clock when viewed from the end
(Figure 40).
8. Secure the cover latches.
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.
Crankcase capacity is approximately 3.3 L (3.5 US
qt) with the filter.
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.
Note:
The best time to check the engine oil is when
the engine is cool before it has been started for the
day. If it has already been run, allow the oil to drain
back down to the sump for at least 10 minutes before
checking. If the oil level is at or below the Add mark
on the dipstick, add oil to bring the oil level to the Full
mark. Do not overfill. If the oil level is between the
Full and Add marks, additional oil is not required.
The engine uses any high-quality 10W-30 detergent
oil having the American Petroleum Institute (API)
service classification SJ, SK, SL, SM, or higher.
Choose a viscosity according to the table in
37
Figure 41.
