Checking The Engine-Oil Level - Toro 25450 Operator's Manual

Checking the Engine-Oil Level

Service Interval: Before each use or daily
Note: The engine is shipped with oil in the crankcase;
however, check the oil level before and after you first start
the engine.
Oil specification: API classification of CJ-4 or higher
Use only high-quality SAE 15W-40 heavy-duty engine oil with
an API classification of CJ-4 or higher.
While SAE 15W-40 oil with an API classification of CJ-4 or
higher is recommended for most climates, refer to
for oil viscosity recommendations for extreme climates.
Figure 22
Note: Limited use of low-viscosity oils such as SAE 10W-30
with an API classification of CJ-4 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.
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 or higher. See the Parts Catalog
for part numbers. Also, refer to the engine operator's manual,
included with the machine, for further recommendations.
Important: If the oil level in the crankcase is too low
or too high and you run the engine, you may damage
the engine.
Note: The best time to check the engine oil is when the
engine is cool before it has been started for the day. If the oil
level is at or below the Add mark on the dipstick, add oil to
the engine to bring the oil level up to the Full mark. Do not
overfill. If the oil level is between the Full and Add marks on
the dipstick, you do not need to add oil.
1. Ensure that the machine is on a level surface.
2. Lower all attachments, set the parking brake, stop the
engine, and remove the key.
Note: If you have run the engine, allow at least 15
minutes for the engine oil to settle in the crankcase.
3. Remove the left-side panel; refer to
Panels (page 45).
4. Remove the dipstick and wipe it clean with a clean
cloth (Figure 23).

Note: The oil level on the dipstick should be between
the H (high) mark and L (low) mark.
•
If the oil level is too low, slowly pour a small
amount of the specified oil into the oil-filler neck
(Figure 65) and wait 3 minutes; refer to step
Filling the Engine with Oil (page
Important: Do not overfill the engine with oil.
•
If the oil level is too high, drain the excess oil until
you obtain the correct oil level on the dipstick;
refer to Draining the Engine Oil (page
4 through 6 until the oil level is correct.
