Maintenance Instructions KOHLER TIPS/LUBRICATION
Oil
● Use only multi-viscosity oils as specied with the
viscosity matching ambient temperatures for the
en gine operating conditions. This will aid start-
ing in cold weather and assure proper lubrica-
tion in hot weather.
● Use only Kohler oil lters. Aftermarket lters
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 o 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
The engine is serviced with Kohler PRO
®
10W-50
synthetic oil and a Kohler PRO
®
lter from the factory.
Both are rated for 300 hour oil change intervals. A
break-in engine oil change is not required. The en-
gine crankcase oil and the lter must be changed af-
ter every 300 hours of operation.
NOTE: Kohler PRO
®
oil and lter are not required,
but recommended. If conventional oil and lters are
used in the tractor, the oil must be changed after ev-
ery 100 hours of operation, and the lter must be
changed after every 200 hours. See the Specica-
tions section for details on which oil and lters are
recommended.
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 ve (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 o 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 sucient 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 Specications
for proper crankcase lubricant. Fill up to, but
not above, the “F” mark on the dipstick.
IMPORTANT: DO NOT overll the crankcase
(oil above “F” mark) as this CAN result in en-
gine overheating, loss of power, and possible
en gine damage.
