Maintenance Instructions<br />
LUBRICATION<br />
LUBRICATION<br />
Proper lubrication is an important maintenance procedure.<br />
It reduces wear and makes the machine quieter<br />
and easier to operate.<br />
Engine Oil<br />
Engine Break-In Oil<br />
WARNING<br />
DO NOT attempt to lubricate the machine<br />
with the engine running. Disengage the<br />
PTO clutch, shut off the machine, and remove<br />
the ignition key.<br />
No special break-in oil is required. The engine is<br />
serviced with 10W-30, Service Class SG oil from the<br />
factory. Change the oil after the initial engine breakin<br />
period of 5 hours. Thereafter, change oil after<br />
every 100 hours of operation.<br />
3. Remove the dipstick, wipe off with a clean rag,<br />
then reinsert the dipstick into the tube and press<br />
all the way down.<br />
4. Remove the dipstick again and check the oil level<br />
on the dipstick. The oil level should be within<br />
the “Operating Range” on the dipstick (between<br />
the “L” mark and the “F” mark).<br />
IMPORTANT: DO NOT operate engine without<br />
a sufficient oil supply in the crankcase. DO NOT<br />
operate with the oil level below the “L” mark or<br />
above the “F” mark on the dipstick.<br />
5. If additional oil is needed, refer to Specifications<br />
for proper crankcase lubricant. Fill up to, but<br />
not above, the “F” mark on the dipstick.<br />
IMPORTANT: DO NOT overfill the crankcase<br />
(oil above “F” mark) as this CAN result in engine<br />
overheating, loss of power, and possible engine<br />
damage.<br />
Checking Engine Crankcase Oil Level<br />
Check the engine crankcase oil level before use and<br />
after each 8 hours of continuous operation.<br />
IMPORTANT: The importance of checking and<br />
maintaining the proper crankcase oil level cannot be<br />
overemphasized. Check the oil level BEFORE<br />
EACH USE.<br />
1. Park the mower on a level surface with the engine<br />
stopped. Also, make sure the engine is<br />
cool and oil has had time to drain into the sump<br />
[allow at least five (5) minutes after stopping<br />
the engine].<br />
IMPORTANT: NEVER check or add oil with the<br />
engine running.<br />
2. Before removing the dipstick, clean the area<br />
around the dipstick to keep any dirt or debris out<br />
of the engine.<br />
