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 SG oil from the
factory. Change the oil after the initial engine break-
in period of 8 hours. Thereafter, change oil after
every 50 hours of operation.
Checking Engine Crankcase Oil Level
Check the engine crankcase oil level before use and
after each 5 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 opening in the engine block
to keep any dirt or debris out of the engine.
3. Unscrew and remove the ller plug/dipstick and
wipe off with a clean rag. Insert dipstick into
ller hole but DO NOT screw it in to check the
oil level. Remove the dipstick and check the
level. The oil level should be within the safe
range (between the H and L marks on the dip-
stick).
IMPORTANT: DO NOT operate engine without
a sufcient oil supply in the crankcase. DO NOT
operate with oil level below the LOW (L) mark or
above the FULL (H) mark on the dipstick.

for proper crankcase lubricant. Fill to the FULL

IMPORTANT: DO NOT overll crankcase [oil
above FULL (H) level] as this CAN result in en-
gine overheating, loss of power, and possible
engine damage.
