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 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 engine­ 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 press all the way down.

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).

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.

5.If additional oil is needed, refer to Specifications 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 engine­ damage.
