16. ENGINE OIL REPLACEMENT
IMPORTANT:
・ The engine oil should be replaced with new 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 200 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,2.
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 beforehand 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 top of engine and
pour in new engine oil through the oil filler. Be sure
to use oil recommended by ISEKI. Refer to " 2.
ENGINE OIL LEVEL ".
Engine oil capacity : 2.4-3.5 liters (SF224), 3.0-4.8 liters (SF235)
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 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.
