overheat and fail if you use a size other than specified.
Removing the Reel

the Bump Knob

clockwise (Fig. 29). Inspect the
captured bolt inside the Bump Knob to make sure it
moves freely. Replace the Bump Knob if it is
damaged.
2.
Remove the inner reel and spring (Fig. 29).
3.
Use a clean cloth to clean the inner surface of the
reel housing (Fig. 39).
NOTE: Always clean the reel, reel housing, and shaft
before reassembling the cutting head.
4.
Check the indexing teeth on the reel and reel
housing for wear. If necessary, remove any burrs or
replace the reel or reel housing (Fig. 39).
Winding the Reel
1. Take approximately
40 feet (12.2 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 reel.
Pull the ends through equally until the loop is as
small as possible (Fig. 31).
