18. STEERING WHEEL (TOE-IN)
Start the engine and turn the steering wheel lightly in both
directions to check to see the wheel turns smoothly.
Make sure that the tire toe-in is properly set. Improper toe-
in causes unstable steering of the front mower: the front
mower has a tendency to turn in one direction, right or left
or the steering wheel turns unexpectedly.
Proper toe-in: A-B = 1 to 10mm (0 to 0.4 in.)
19. ENGINE OIL REPLACEMENT
IMPORTANT:
•
The engine oil should be replaced with fresh oil in
accordance with operation hours. If not, overly used oil
will cause engine troubles.
• The first replacement should be done after the initial
50 hours of operation and then after every 1
5 0 hours
of operation.
When replacing engine oil, place the front mower on level,
hard ground. The engine oil drain is located bottom of the
engine oil pan, which is accessible from the left side of the
front mower. SF370 has 2 drains on both left and right side.
a. Place a tray or the like under the oil drain to receive
drained oil.
b. The engine should be warmed up for 10 minutes or so
ahead of time to heat the oil to lower its viscosity for
compete drainage.
c. Remove the drain plug,1, allowing the used oil drain
out completely.
d. When the used oil has drained out completely, screw
the drain plug back in securely.
e. Remove the oil filler cap,3, at the right sidewall of
engine and pour in fresh engine oil through the oil filler.
Be sure to use oil recommended by ISEKI. Refer to
“2. ENGINE OIL LEVEL” .
f. After engine oil replacement, start the engine and let it
idle for a while.
g. Then stop it and wait for a while until the engine oil
comes down into the oil pan, 2. Now check the oil level
to check to see if it is at the upper limit or not. When
the level is low, replenish until the level reaches the
upper limit.
IMPORTANT: Never fill over the upper limit, or it may
cause engine trouble.
h. Make sure that there is no oil leakage through the
drain plug and oil filter.
