Operation
Note: Determine the left and right sides of the machine
from the normal operating position.
Before Operating
CAUTION
If you leave the key in the ignition switch, someone
could accidently start the engine and seriously
injure you or other bystanders.
Remove the key from the ignition before you do any
maintenance.
Checking the Engine Oil
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.
The crankcase capacity is 5.7 L (6 qt) 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 0°F)
•
Alternate oil: SAE 10W-30 or 5W-30 (all temperatures)
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, no additional oil is required.
1. Park the machine on a level surface. Unlock the engine
cover latches.
2. Open the engine cover.
3. Remove the dipstick, wipe it clean, install the dipstick
into the tube, and pull it out again. The oil level should
be between the full and add marks

4. If the oil level is low, remove the fill cap
add oil until it is between the full and add marks. Do
not overfill.
5. Install the oil fill cap and dipstick.
6. Close the engine cover and secure it with the latches.
1. Carefully remove the radiator cap and expansion tank
cap
(Figure

CAUTION
If the engine has been running, the
pressurized, hot coolant can escape and cause
burns.
• Do not open the radiator cap when the
engine is running.
• Use a rag when opening the radiator cap,
and open the cap slowly to allow steam to
escape.
2. Check the coolant level in the radiator. The radiator
should be filled to the top of the filler neck and the
expansion tank filled to the Full mark.
