Servicing The Engine Oil And Filter - Toro 4045 Operator's Manual

Servicing the Air-cleaner Filter
Service Interval: Every 250 hours
Replace the filters only when the "Check Air Filter"
indicator appears on the display screen; refer to
Checking the Air-cleaner Indicator (page
Note: Contact your Authorized Toro Dealer to order
replacement filters.
1. Park the machine on a level surface, stop the engine,
and remove the ignition key.
2. Open the rear-access door.
3. Before removing the filter, clean out all debris from the
inside of the filter body using low-pressure air at 275
kPa (40 psi).
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 the primary filter
is removed.
4. Using the air-filter handles, remove the primary filter
from the air-cleaner cover
Important: Do not clean the used filter.

Servicing the Engine Oil and
Filter
The engine is shipped with oil in the crankcase; however,
check the oil level before and after you first start the engine.
Crankcase capacity: 7.5 L (7.9 US qt) with the filter.
Use only high-quality low ash SAE 15W-40 heavy-duty engine
oil with an API classification of CJ-4 (ACEA E9) or higher.
While low ash SAE 15W-40 oil with an API classification of
CJ-4 (ACEA E9) or higher is recommended for most climates,
refer to Figure 120 for oil viscosity recommendations for
extreme climates.

Note: Limited use of low-viscosity oils such as SAE 10W-30
with an API classification of CJ-4 (ACEA E9) or higher
can be used for easier starting and providing sufficient oil
flow at ambient temperatures below -5°C (23°F). However,
continuous use of low viscosity oil can decrease engine life
because of wear (Figure
Toro Premium Engine Oil is available from an Authorized
Toro Service Dealer in either 15W-40 or 10W-30 viscosity
with API classification CJ-4 (ACEA E9) or higher. See the
parts catalog for part numbers.
