Operation; Think Safety First; Checking The Engine Oil - Toro Greensmaster 3420 TriFlex Operator's Manual

Operation

Note: Determine the left and right sides of the machine
from the normal operating position.

Think Safety First

Please carefully read all of the safety instructions and symbols
in the safety section. Knowing this information could help
you or bystanders avoid injury.
The use of protective equipment, such as but not limited to,
for eyes, ears, feet, and head is recommended.

Checking the Engine Oil

The engine is shipped with oil in the crankcase; however, the
oil level must be checked before and after the engine is first
started.
Crankcase capacity is approximately 3.9 quarts (3.7 l) 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 10W–30
•
Alternate oil: SAE 15W–40
Toro Premium Engine oil is available from your distributor in
the 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 oil addition
is required.
Important: Be sure to keep the engine oil level between
the upper and lower limits on the oil gauge. Engine
failure may occur as a result of over filling or under
filling the engine oil.
1. Position the machine on a level surface.
2. Remove the dipstick and wipe it with a clean rag
(Figure 28). Push the dipstick into the tube and make
sure it is seated fully. Remove the dipstick from the
tube and check the level of oil. If the oil level is low,
remove the filler cap from the valve cover and slowly
add enough oil to raise the level to the Full mark on the
dipstick. Add the oil slowly and check the level often
during this process. Do not overfill.
Important: Make sure that the dipstick is removed
while filling the engine with oil. When adding
engine oil or filling oil, there must be clearance
between the oil fill device and the oil fill hole in the
valve cover as shown in Figure 27. This clearance
is necessary to permit venting when filling, which
prevents oil from overrunning into breather.
1. Note clearance
1. Filler cap
3. Replace the dipstick.
4. Start and run the engine at idle for 30 seconds, then
shut the engine off. Wait 30 seconds, then repeat steps
2–3.
Important: Check the level of oil every 8 operating
hours or daily. Change the oil and filter initially
after the first 50 hours of operation, thereafter
change the oil and the filter every 150 hours.
However, change the oil more frequently when
the engine is operated in extremely dusty or dirty
conditions.
5. Install the filler cap and dipstick firmly in place.
