Re-filling the Crankcase with Oil
IMPORTANT:
Always check the level on the dipstick as
instructed on page 22 before adding more oil. Do NOT
overfill.
NOTE:
For the proper oil type, refer to the chart on
page 22 of this manual.
1.
Clean the area around the oil fill tube to prevent
debris from entering the crankcase.
2.
Slowly
pour oil into the fill tube. Fill the crankcase
until the oil level reaches the full (
F
) mark on the
dipstick (Refer to Page 22).
3.
Reinstall the oil fill cap/dipstick securely into the oil
fill tube.
IMPORTANT:
The oil fill cap/dipstick
must be installed
securely onto the tube at all times when the engine
is operating
. Severe engine damage could result from
a failure to do so.
4.
Start the tractor engine and allow it to run for thirty
seconds, then stop the engine and remove the
ignition key.
5.
Check the oil level and add oil if necessary.
Do not
overfill the engine crankcase
.
6.
Examine the area around the base of the oil fill
tube, the oil filter adapter, and the oil drain valve for
leaks before operating the tractor.
IMPORTANT:
If leaks are present, have your engine
serviced by an authorized Toro service dealer before
operating the tractor.
Air Filter
The engine is equipped with a replaceable, high density
paper air cleaner element. Always examine the air
cleaner
before starting the engine.
Check for a
buildup of dirt and debris around the air cleaner system.
Keep this area clean. Also check for loose or damaged
components. Replace all bent or damaged air cleaner
components.
NOTE:
Starting the tractor with loose or damaged air
cleaner components could allow unfiltered air into the
engine causing premature wear and failure.
Service Paper Element
The paper element should be replaced at least once a
season, or every
100 hours
of operation. Replace
more frequently if the tractor is operated under
extremely dusty conditions. To replace the paper
element, proceed as follows:
•
Pivot the air cleaner cover upward and unhook the
wire latch which secures the element in place.
•
Remove the air cleaner element with precleaner.
•
Carefully remove the precleaner from the element
and service as instructed earlier in this section.
IMPORTANT:
Do
not
wash the paper element or use
pressurized air
,
as this will damage the element.
Examine the element and discard if dirt and/or damage
is present.
NOTE:
Handle new elements carefully; do not use if
the sealing surfaces are bent or damaged.
•
If any loose dirt or debris fell on the air cleaner base
when the element was removed, carefully remove it
and wipe the base clean. Be careful that none of it
drops into the intake.
•
Check the air cleaner base. Make sure it is secured
and not damaged. Also check the air cleaner cover
for damage or improper fit. Replace all damaged air
cleaner components.
•
Install the precleaner over the new paper element
and reinstall the element.
•
Lower the wire latch to secure the element in place
and pivot the air cleaner cover downward.
Spark Plug
Every two years or
200 hours
of operation, remove the
spark plug, check its condition, and reset the gap or
replace with a new plug as necessary. Spark plug
replacement is recommended at
500 hours
.
1.
Lift the tractor’s hood by pivoting it forward.
NOTE:
Removing the tractor’s hood may ease the
following steps, but is not necessary.
2.
Carefully pull the spark plug wire boot off of the
spark plug.
3.
Before removing the spark plug, clean the area
around the base of the plug to keep dirt and debris
out of the engine.
4.
Using a ratchet with a 5/8-inch spark plug socket,
remove the spark plug and check its condition.
5.
Replace the plug if worn, dirty or damaged. Reuse
only after resetting the gap as instructed.
NOTE:
Do not clean the spark plug using an abrasive
grit. Some grit could remain in the spark plug and enter
the engine causing extensive wear and damage.
6.
Check the gap using a feeler gauge and adjust, if
necessary, by carefully bending the ground
electrode. See Figure 18. Set the spark plug gap to
0.030 in (0.76 mm).
