Filling The Fuel Tank; Checking The Engine-Oil Level; Adjusting The Cutting Height - Toro 20339 Operator's Manual

Filling the Fuel Tank

•
For best results, use only clean, fresh, unleaded gasoline
with an octane rating of 87 or higher ((R+M)/2 rating
method).
•
ETHANOL: Gasoline with up to 10% ethanol (gasohol)
or 15% MTBE (methyl tertiary butyl ether) by volume
is acceptable. Ethanol and MTBE are not the same.
Gasoline with 15% ethanol (E15) by volume is not
approved for use. Never use gasoline that contains more
than 10% ethanol by volume, such as E15 (contains 15%
ethanol), E20 (contains 20% ethanol), or E85 (contains
up to 85% ethanol ). Using unapproved gasoline may
cause performance problems and/or engine damage
which may not be covered under warranty.
•
Do not use gasoline containing methanol.
•
Do not store fuel either in the fuel tank or in fuel
containers over the winter unless fuel stabilizer has been
added to the fuel.
•
Do not add oil to gasoline.
Important: To reduce starting problems, add fuel
stabilizer to the fuel all season, mixing it with gasoline
less than 30 days old.
Refer to your engine manual for additional information.
1. Do not fill the fuel tank above the bottom of the fuel tank
neck.

Checking the Engine-Oil Level

Service Interval: Before each use or daily
1. Move the machine to a level surface.
2. Remove the dipstick by rotating the cap
counterclockwise and pulling it out
Figure 11
(Figure 12).
3. Wipe the dipstick clean with a clean cloth.
4. Insert the dipstick into the oil-fill tube, then remove
the dipstick.
5. Read the oil level on the dipstick
•
If the oil is below the Add mark on the dipstick,
slowly pour a small amount of oil into the oil-fill
tube, wait 3 minutes, and then repeat steps
through
the dipstick.
•
If the oil is above the Full mark on the dipstick,
drain the excess oil until the oil level is at the Full
mark on the dipstick. To drain the excess oil, refer
to Changing the Engine Oil (page
Important: If the oil level in the crankcase is too
low or too high and you run the engine, you may
damage the engine.
6. Install the dipstick into the oil-fill tube securely.
