WARNING: To prevent extensive engine wear and damage to the unit, always maintain the proper oil level in the crankcase. Never operate the unit with a low 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 a flat, level surface with the cutting head shield hanging off a work bench or table to get a proper oil level reading (Fig. 23).

4. | Remove the oil fill plug (Fig. 25). |
5. | Look into the oil fill hole, use a flashlight if |
| needed. The oil should be just touching the |
| inner most thread (Fig. 24). |

NOTE: Line installation DOES NOT require removal or disassembly of the cutting head.
1.Align the arrows on the cutting head knob with the outer spool eyelets, if they are not already. (Fig. 16)
2.Using 10.5 ft. (3.2 m) of 0.095 in. (2.41 mm) replacement line push an end of the line through one of the eyelets until it protrudes through the opposite side. Continue pushing or pulling the line until the line is evenly distributed, so approximately 5 ft. (1.5 m) is visible from both sides of the cutting head. (Fig. 17)
3.Hold the cutting head knob and turn the cutting head counterclockwise to wind the line around the spool until 5 in. (12.7 cm) is protruding from each side of the cutting head. (Fig. 18)
NOTE: If winding the line from a large spool of line, cut the line from the spool so that it measures 5” from the eyelet.
4.Start the unit and bump the cutting head on the ground until the desired cutting length is achieved.
REMOVING THE OLD LINE OR OBSTRUCTIONS
NOTE: There should only be a need to remove the bump cap if the old line gets jammed or an obstruction preventing the new line from being installed properly.
1.Firmly press in on the tabs that are on each side of the cutting head. (Fig. 19)

amount of oil to the oil fill hole and recheck |
(Fig. 24). Repeat this procedure until the oil |
level reaches the inner most thread on the |

NOTE: Do not overfill the unit.
NOTE: Make sure the
CHANGING THE OIL
CAUTION: Wear gloves to prevent injury when handling the unit.
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. 26). 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. 28).

NOTE: It may be easier to press in and then up on one tab at a time.
2.Remove the cap either by letting it pop off or a slight wiggle of the cap may be required and pull it off the outer spool (Fig. 20).
3.Remove any old line from the inner reel or obstructions from the outer spool. (Fig. 21)
4.Place the inner reel back into the outer spool (Fig. 20).

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. 29). 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. 24).
6.Replace the oil fill plug.
7.Reconnect the spark plug boot.
5.Replace the bump cap by aligning the tabs of the bump cap with the tab lock windows of the outer spool and press down firmly until both tabs snap back into place. (Fig. 22)
To install new line, please refer to the Line Installation section.
