Oil
● Use only multi-viscosity oils as specified with
the viscosity matching ambient temperatures
for the en gine operating conditions. This will
aid starting
in cold weather and assure proper
lubrication in hot weather.
● Use only Kohler oil filters.
Aftermarket filters
may not seal properly
and/or have the incor-
rect pressure relief valve for proper lubrication.
LUBRICATION
WARNING
DO NOT attempt to lubricate the machine
with the engine running. Disengage the
PTO clutch, shut off the machine, and re-
move the ignition key.
Proper lubrication is an important maintenance
pro cedure. It reduces wear and makes the
machine quieter and easier to operate.
Engine Oil
Engine Break-In Oil
No special break-in oil is required
. The engine
is serviced with 10W-30, Service Class SJ oil from
the factory. Change the oil after the initial engine
break-in period
of
5 hours
. Thereafter, change
oil
after every 100 hours
of operation.
Checking Engine Crankcase Oil Level
Check the engine crankcase oil level before use
and
after each 8 hours
of continuous operation.
IMPORTANT:
The importance of checking and
maintaining the proper crankcase oil level cannot
be overemphasized. Check the oil level
BEFORE
EACH USE.
1. Park the mower
on a level surface with the
en gine stopped
. Also, make sure the engine
is cool and oil has had time to drain into the
sump [allow
at least five (5) minutes
after
stopping the engine].
IMPORTANT: NEVER
check or add oil with
the engine running.
2. Before removing the dipstick, clean the area
around the dipstick to keep any dirt or debris
out of the engine.
3.
Remove the dipstick, wipe off with a clean rag,
then reinsert the dipstick into the tube and
press all the way down.
4. Remove the dipstick again and check the oil
lev el on the dipstick. The oil level should be
within the “Operating Range” on the dipstick
(between the “L” mark and the “F” mark).
IMPORTANT: DO NOT
operate engine
without a sufficient oil supply in the crankcase.
DO NOT
operate with the oil level below the
“L” mark or above the “F” mark on the dipstick.
5. If additional oil is needed, refer to
Specifica
-
tions on page 3
for proper crankcase lubri-
cant.
Fill up to, but not above, the “F” mark
on the dipstick.
IMPORTANT: DO NOT
overfill the crank-
case (oil above “F” mark) as this
CAN
result in
engine overheating, loss of power, and pos-
sible en gine damage.
