AIR FILTER MAINTENANCE

Cleaning the Air Filter

Failure to maintain your air filter properly can
result in poor performance or can cause
permanent damage to your engine.
1. Open the air filter cover. Push the tab on the

under side of the cover inward. Then pull the
air filter cover out and up. (Fig. 41).

2. Remove the air filter (Fig. 41).
3. Wash the filter in detergent and water. Rinse

the filter thoroughly and allow it to dry.

4. Apply enough clean SAE 30 motor oil to

lightly coat the filter.

5. Squeeze the filter to spread and remove

excess oil.

6. Replace the filter (Fig. 42).

NOTE:

If the unit is operated without the air filter,

you will VOID the warranty.

7. Reinstall the air filter cover. Position the slots

on the top of the air filter cover onto the tabs at the top of the back plate
(Fig. 42).

8. Swing the cover down until the tab on the air filter backplate snaps into

place in the slot on the air filter cover (Fig. 41).

WARNING:

To avoid serious personal injury, always turn the

unit off and allow it to cool before you clean or service it.

MAINTENANCE AND REPAIR INSTRUCTIONS

SINGLE LINE INSTALLATION

Go To Step 8 for SplitLine™ Installation

6. Take approximately 18 feet (6 m) of new

trimming line, loop it into two equal lengths.
Insert each end of the line through one of the
two holes in the inner reel (Fig. 30). 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. 31). 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.

SPLITLINE™ INSTALLATION

8. Take approximately 9 feet (3 m) of new

trimming line. Insert one end of the line
through one of the two holes in the inner reel
(Fig. 32). 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. 33).

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. 33).

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. 34). 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 counterclockwise.
Tighten securely.

INSTALLING A PREWOUND REEL

1. Hold the outer spool with one hand and unscrew the bump knob clockwise

(Fig. 27). 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. 27).
3. Remove the spring from the old inner reel (Fig. 27).
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. 35).
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. Tighten securely.

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. 36).

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. 36).
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. 37).

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. 38). 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. 39).

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. 40). 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. 36).

6. Replace the oil fill plug.
7. Reconnect the spark plug boot.

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 a flat, level surface with the

cutting head shield hanging off a work bench or
table to get a proper oil level reading (Fig. 35).

3. Keep dirt, grass clippings and other debris out

of the engine. Clean the area around the
dipstick before removing it.
