Maintenance Instructions

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
procedure. 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 ser-
viced with 10W-30, Service Class SJ oil from the fac-
tory. 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. 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 hold
all the way down. For correct oil level measure-
ment, do not turn cap on threads.
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).
WARNING
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.
If additional oil is needed, refer to Specifications
5.
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 en-
gine overheating, loss of power, and possible
en gine damage.
