Viscosity table
Note: To prevent extensive engine wear or
damage, always maintain the proper oil level in
the crankcase. Never operate the engine with the
oil level below the "L"(LOW) mark or over the
"F" (FULL) mark on the dipstick.
Changing the Engine Oil
Service Interval: After the first 5 hours
Every 100 hours (change
it more often under a
heavy load or in high
temperatures) (Kohler
Engine).
1. Park the machine so that the drain side is slightly
lower than the opposite side to ensure the oil
drains completely.
2. Start the engine and let it run until warm. This
warms the oil so it drains better.
3. Disengage the blade control switch and ensure
the parking brake is engaged.
4. Stop the engine, remove the key, and wait for all
moving parts to stop before leaving the operating
position.
