INSTALLING A PREWOUND REEL

1.Hold the outer spool with one hand and unscrew the Bump Knob clockwise (Fig. 6-1, Pg. 18). Inspect the bolt inside the Bump Knob to make sure it moves freely. Replace the Bump Knob if damaged.

2.Remove the old inner reel from the outer spool (Fig. 6-1, Pg. 18).

3.Remove the spring from the old inner reel (Fig. 6-1, Pg. 18).

4.Place the spring in the new inner reel.

NOTE: The spring must be assembled on the inner reel before reassembling the cutting attachment.

5.Insert the ends of the line through the eyelets in the outer spool (Fig. 6-8).

6.Place the new inner reel inside the outer spool. Push the inner reel and outer spool together. While holding the inner reel and outer spool, grasp the ends and pull firmly to release the line from the holding slots in the spool.

7.Hold the inner reel in place and install the Bump Knob by turning counterclockwise.

CHECKING THE OIL LEVEL

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 prop- er 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. 6-9).

6.If the level is low, add a small amount of oil to the oil fill hole and recheck (Fig. 6-10). Repeat until the oil level reaches the top of the dipstick.

NOTE: Do not overfill the unit.

NOTE: Make sure the O-ring is in place on the oil fill plug/dipstick when checking and changing the oil (Fig. 6-10).

CHANGING THE OIL

For a new engine, change the oil after the first 10 hours of operation. Thereafter, change the oil after every 25 hours or before storing the unit for an extended period of time.

It is best to change the oil while the engine is still warm. The oil will flow freely and carry away more impurities.

Wear gloves to prevent injury when handling the unit.
