Engine Maintenance
Servicing the Air Cleaner
Check the air cleaner body for damage that could cause
an air leak. Ensure that the dust cap is tightly sealed
onto the air cleaner. Replace a damaged air cleaner body.
Squeeze the valve (Figure 38) before each use to clear it
of dust and debris. Service the air cleaner filter every
100 hours.

2. Dust cap
Note: Service the air cleaner more frequently if
operating conditions are extremely dusty or sandy.
Cleaning the Filter and Housing
Service Interval: Before each use or daily
Important: Do not remove the air cleaner in an
attempt to clean it. This increases the chance of
dirt and debris entering the engine.
1. Set the parking brake, stop the pump, stop the
engine, and remove the ignition key.
2. Raise the passenger seat.
3. Loosen the air cleaner strap that secures the air
cleaner cover to the air cleaner body (Figure 38) and
separate the cover from the body.
4. Use low pressure compressed air (40 psi, clean and
dry), to remove dirt and debris from the inside of the
air cleaner cover and around the air filter.
Important: Avoid high pressure compressed air
which can force dirt through the filter and into
the engine.
5. Inspect the filter and replace it if it is damaged.
6. Install the cover with the valve pointing down at a
5–7 o'clock position when viewed from the end.
7. Secure the straps (Figure 38).

8. Remove the rubber valve cover from the air cleaner
cover.
9. Clean the valve and replace it on the air cleaner cover.
Installing a New Filter Element
Service Interval: Every 100 hours
1. If you are installing a new filter, inspect it for
shipping damage. Check the sealing end of the filter.
Important: Do not install a damaged filter.
2. Gently slide the old filter out of the air cleaner body
to reduce the amount of dust dislodged.
Note: Avoid knocking the filter against the air
cleaner body.
3. Insert the filter into the air cleaner body. Ensure 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.
4. Install the cover with the valve pointing down and
secure the straps (Figure 38).
5. Squeeze the element to distribute the oil.
Servicing the Engine Oil
Change the engine oil and the oil filter after the first
50 operating hours and every 150 operating hours
thereafter.
Crankcase Capacity is 4.9 qt (4.7 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 15W40 (above 0 degrees F)
• Alternate oil: SAE 10W30 or 5W30 (all temperatures)
Toro Premium Engine Oil is available from your
distributor in either 15W40 or 10W30 viscosity. See the
Parts Catalog for part numbers.
Check the Engine Oil
Service Interval: Before each use or daily
Every 400 hours/Yearly (whichever
comes first)
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
