LINE INSTALLATION
WARNING:
Never use metal-reinforced line,
wire, chain or rope. These can break off and
become dangerous projectiles.
This section covers both SplitLine™ and standard single line
installation.
Always use original equipment manufacturer 0.095 in. (2.41 mm)
replacement line. Line other than the specified may make the
engine overheat or fail.
There are two methods to replace the trimming line:
• Wind the inner reel with new line
• Install a prewound inner reel
Removing the Existing Inner Reel
1. Hold the outer spool with one hand and unscrew the Bump
Knob™ counterclockwise (Fig. 15). Inspect the bolt inside
the Bump Knob to make sure it moves freely. Replace the
Bump Knob if damaged.
2. Remove the inner reel from the outer spool (Fig. 16).
3. Remove spring from the inner reel (Fig. 16).
4. Use a clean cloth to clean the the inner reel, spring, shaft,
and inner surface of the outer spool.
5. Check the indexing teeth on the inner reel and outer spool for wear
(Fig. 17). If necessary, remove burrs or replace the reel and spool.
NOTE: Always use the correct line length when installing
trimming line on
Indexing Teeth
the unit. The line
may not release
properly if the
line is too long.
Single Line Installation
Go To Step 8 for
SplitLine™ Installation:
6. Take approximately
20 feet (6 m) of new
trimming line, loop it
into two equal
Fig. 17
lengths. Insert each
end of the line
through one of the
two holes in the inner
reel (Fig. 18). Pull the
line through the inner
reel so that the loop is
as small as possible.
7. Wind the lines in tight
even layers, onto the
reel (Fig. 19). Wind
the line in the
direction indicated on

the inner reel. Place
your index finger
between the two lines
to stop the lines from
overlapping. Do not
overlap the ends of
the line. Proceed to
step 11.

through one of the
two holes in the inner reel (Fig. 20). Pull the line through the inner reel until only about 4 inches is left out.
9. Insert the end of the line into the open hole in the inner reel and pull the line tight to make the loop
as small as possible (Fig. 20).
10. Before winding, split the line back about 6 inches.
11. Wind the line in tight even layers in the direction indicated on the inner reel.
NOTE: Failure to wind the line in the direction indicated will cause the cutting attachment to operate incorrectly.
12. Insert the ends of the line into the two holding slots (Fig. 21).
13. Insert the ends of the line through the eyelets in the outer spool and place inner reel with spring inside
the outer spool (Fig. 22). 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 reel.
NOTE: The spring must be assembled on the inner reel before reassembling the cutting attachment.
14. Hold the inner reel in place and install the bump knob by turning clockwise. Tighten securely.
INSTALLING A PREWOUND REEL
1. Hold the outer spool with one hand and unscrew the bump knob counterclockwise (Fig. 15). 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. 16).
3. Remove the spring from the old inner reel (Fig. 16).
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. 22).
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 clockwise. Tighten securely.
INSTALLATION OF THE SPEEDLOCK™
Removing the Existing Inner Reel
Refer to Removing the Existing Inner Reel in the Maintenance and
Repair Insturctions section that can be found in the operator's manual.
Installing the SpeedLock™
1. After removing the inner reel, place the SpeedLock™ onto the
shaft, making sure to align the arrows with the eyelets in the outer
spool (Fig. 23).
2. Place the spring over the shaft and into the recess in the
SpeedLock™ Spool (Fig. 23).
3. While holding the outer spool in place, insert the bolt located
in the Bump Knob™ through the end of the spring and into
the end of the shaft (Fig. 23).
4. While slightly compessing the spring, screw the Bump Knob™
clockwise into the shaft (Fig. 23). Tighten Securely.
Installing the Trimming Line
1. Align the arrows on the SpeedLock™ with the eyelets on the
outer spool (Fig. 24).
2. Insert a piece of precut spiral line, P/N 49UFSHLL953, into an
eyelet on the outer spool (Fig. 24).
3. Push the line into the SpeedLock™ until it starts to show from

CHECKING THE OIL LEVEL
WARNING:
cool before you clean or service it.
The importance of
checking and
maintaining the proper oil
level in the crankcase
cannot be
Loop
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.
27).
3. Keep dirt, grass clippings and other debris out of the engine.
Clean the area around the dipstick before removing it.
Loop
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 inner most thread (Fig. 28).
6. If the oil level is not touching the inner most thread on the oil
fill hole, add a small amount of oil to the oil fill hole and
recheck (Fig. 29). Repeat this procedure until the oil level
reaches the inner most 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. 29).
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.
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. 30). 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.
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.
31). 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. 31).
6. Replace the oil fill plug.
7. Reconnect the spark plug
boot.
