Checking The Oil Level; Changing The Oil - MTD Yard-Man YM26SS Manual Del Operador

SECTION 7: MAINTENANCE AND REPAIR INSTRUCTIONS

CHECKING THE OIL LEVEL

CAUTION: To prevent extensive engine wear
and damage to the unit, always maintain the
proper oil level in the crankcase. Never
operate the unit with the oil level below the
bottom of the dipstick.
The importance of checking and maintaining the proper
oil level in the crankcase cannot be overemphasized.
Check oil before each use:
1. Stop engine and allow oil to drain into the crankcase.
2. Place the unit on a flat, level surface to get a proper
oil level reading.
3. Keep dirt, grass clippings, etc., out of the engine.
Clean the area around the oil fill plug/dipstick before
removing it.
4. Remove the oil fill plug/dipstick and wipe off oil.
Reinsert it all the way back in.
5. Remove the oil fill plug/dipstick and check oil level.
Oil should be up to the top of the dipstick (Fig. 27).

DANGER: OVERFILLING OIL CRANKCASE
MAY CAUSE SERIOUS PERSONAL INJURY!
The importance of checking and maintaining
the proper oil level in the crank case cannot
be overemphasized. Check oil before each
use and change as needed. See Changing
the Oil below.

CHANGING THE OIL

For a new engine, change the oil after the first 10 hours
of operation. Change the oil while the engine is still
warm. The oil will flow freely and carry away more
impurities.
CAUTION: Wear gloves to prevent injury
when handling the unit.
1. Unplug spark plug wire to eliminate starting.
2. Remove the oil fill plug/dipstick.
3. Pour the oil out of the oil fill hole and into a container
by tipping the unit to a vertical position (Fig. 30).
Allow ample time for complete drainage.
