Checking The Oil Level; Changing The Oil - Craftsman 79194 - 29cc 4 Cycle Gas Trimmer Operator's Manual

CHECKING THE OIL LEVEL
The importance of checking and maintaining the proper oil level in
the crankcase cannot be overemphasized. Check oil before each
use:
1. Stop the engine and allow oil to drain into the crankcase.
2. Place the engine on an elevated, level surface with the cutting
head shield hanging off the surface to get a proper oil level
reading (Fig. 18).

3. Keep dirt, grass clippings and other debris out of the engine.
Clean the area around the dipstick before removing it.
4. Remove the oil fill plug.
5. Look into the oil fill hole, use a flashlight if needed. The oil
should be just touching the innermost thread (Fig. 19).
6. If the oil level is not touching the innermost thread on the oil fill
hole, add a small amount of oil to the oil fill hole and recheck
(Fig. 19). Repeat this procedure until the oil level reaches the
innermost thread on the oil fill hole.
NOTE: Do not overfill the unit.
NOTE: Make sure the O-ring is in place on the oil fill plug when
checking and changing the oil (Fig. 20).

CHANGING THE OIL
_ ARNING: Wear gloves to prevent injury when
handling unit.
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.
1. Unplug spark plug boot to prevent accidental starting.
2. Remove the oil fill plug.
3. Pour the oil out of the oil fill
hole and into a container by
tipping the unit to a vertical
position (Fig. 21). Allow
ample time for complete
drainage.
4. Wipe up any oil residue on
the unit and clean up any oil
that may have spilled.
Dispose of the oil according
to Federal, State and local /
regulations.
5. Refill the crankcase with
3.04 fluid ounce (90 ml) of
SAE 30 SF, SG, SH oil. Fig. 21
NOTE: Use the bottle and spout saved from initial use to measure
the correct amount of oil. The top of the label on the bottle
measures approximately 3.04 ounces (90 ml) (Fig. 22).
Check the level; see Checking the Oil Level. If the level is
low, add a small amount of oil and recheck. Do not overfill
(Fig. 22).
