Filling The Fuel Tank - Toro 04520 Operator's Manual

2. Remove the dipstick and wipe it with a clean rag
(Figure 25). 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 24. This clearance is necessary to permit
venting when filling, which prevents oil from
overrunning into breather.

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.

Filling the Fuel Tank

Use only clean, fresh diesel fuel or biodiesel fuels with
low (<500 ppm) or ultra low (<15 ppm) sulfur content.
The minimum cetane rating should be 40. Purchase
fuel in quantities that can be used within 180 days to
ensure fuel freshness.
Fuel tank capacity: 6 U.S. gallons (22.7 l)
Use summer grade diesel fuel (No. 2-D) at temperatures
above 20 degrees F (-7 degrees C) and winter grade (No.
1-D or No. 1-D/2-D blend) below that temperature.
Use of winter grade fuel at lower temperatures provides
lower flash point and cold flow characteristics which
will ease starting and reduce fuel filter plugging.
Use of summer grade fuel above 20 degrees F (-7
degrees C) will contribute toward longer fuel pump life
and increased power compared to winter grade fuel.
