Operation; Checking The Engine Oil; Checking The Cooling System - Toro 30864 Operator's Manual

Operation

Note: Determine the left and right sides of the machine
from the normal operating position.
CAUTION
If you leave the key in the ignition switch, someone
could accidently start the engine and seriously
injure you or other bystanders.
Lower the cutting decks to the ground, set the
parking brake and remove the key from the ignition
switch before servicing or making adjustments to
the machine.

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 5.2 liters (5.5 qt) with the filter.
Use high-quality engine oil that meets the following
specifications:
•
API Classification Level Required: CJ-4 or higher.
•
Preferred oil: SAE 15W-40 (above 0°F)
•
Alternate oil: SAE 10W-30 or 5W-30 (all temperatures)
Important: Using non CJ-4 or higher oil will cause
DPF plugging and damage the engine.
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 (Figure 10).

4. If the oil level is low, remove the fill cap (Figure 10)
and 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.

Checking the Cooling System

Clean debris off of the screen, oil cooler, and front of the
radiator daily and more often if conditions are extremely
dusty and dirty. Refer to the section on Removing Debris
from the Cooling System in Maintenance.
The cooling system is filled with a 50/50 solution of water
and permanent ethylene glycol antifreeze. Check the level of
coolant in the expansion tank at the beginning of each day
before starting the engine. The capacity of the cooling system
is 9.5 liters (10.0 quarts).
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.
1. Check the level of coolant in the expansion tank
(Figure 11).
The coolant level should be between the marks on the
side of the tank.
