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 59) 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 59).
2. Remove the cover from the air cleaner body (Figure
59).
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 59).

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 59). 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 59).
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 59) 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 3.8 liters (4 quarts)
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 -17° C (0° F)
•
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.
1. Park the machine on a level surface, lower the
attachment, move the throttle lever to the Slow
position, stop the engine, and remove the key from the
ignition switch. Open the hood.
2. Remove the dipstick (Figure 60), wipe it clean, and
install the dipstick. Remove the dipstick and check the
oil level.
