Installing A Prewound Reel; Checking The Oil Level; Changing The Oil - MTD 890 Manual Del Usuario

NOTE: Always use the correct line length when
installing trimming line on the unit. The line may
not release properly if the line is too long.
Single Line Installation (Fig. 30, a & b)
Go To Step 8 for SplitLine™ Installation.
6. Take approximately 6 m (20 feet) 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. 31). Pull the line through the inner reel so that
the loop is as small as possible (Fig. 31).
7. Wind the lines in tight even layers, onto the reel .
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 (Fig. 30, b)
8. Take approximately 3 m (10 feet) of new trimming
line. Insert one end of the line through one of the two
holes in the inner reel. 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.
10. Before winding, split the line back about 15 cm.
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. 32).
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. 33). 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.
MAINTENANCE AND REPAIR INSTRUCTIONS
5. Insert the ends of the line through the eyelets in the
outer spool (Fig. 33).
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.

CHECKING THE OIL LEVEL

CAUTION: 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 proper
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. 34).
6. If the level is low, add a small amount of oil to the oil
fill hole and recheck. Repeat until the oil level
reaches the top of the dipstick.
NOTE: Do not overfill the unit.
DANGER: OVERFILLING OIL CRANKCASE MAY
CAUSE SERIOUS PERSONAL INJURY! The
importance of checking and maintaining the proper oil
level in the crank case cannot be overemphasized.
Check oil before each use and change as needed.
Refer to Changing the Oil.

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.
CAUTION: Wear gloves to prevent injury when
handling the unit.
1. Unplug spark plug boot to eliminate starting.
2. Remove the oil fill plug/dipstick.
3. Pour the oil out of the oil fill hole and into a container
by tipping the unit to a vertical position (Fig. 35).
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.
