Maintenance Instructions

Lubrication

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
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.
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].
