Maintenance Instructions KOHLER TIPS/LUBRICATION
54
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 incorrect
pressure relief valve for proper lubrication.
LUBRICATION
Proper lubrication is an important maintenance pro-
cedure. It reduces wear and makes the machine qui-
eter 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 SG 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 (200 hour interval for
MTL).
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 Specifications
for proper crankcase lubricant. Fill up to, but
not above, the “F” mark on the dipstick.
IMPORTANT: DO NOT overfill the crankcase
(oil above “F” mark) as this CAN result in engine
overheating, loss of power, and possible en-
gine damage.

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.
