Trimmer Line Assembly - Bump Head
(Select Models only)
1. Press two cover clips inwards on the housing & remove the cover slowly.
Note: Retain the spring within the housing.
2. Remove the remains of worn line from the spool (if any remains).
Note: Remaining line may be sufficient to rewind and reuse if has been tangled
or has retracted back into the housing.
Note: Ensure inside of housing and spool are clean and free of grass & soil
before refilling.
3. Use 6 meters of diameter 2.4mm nylon line*. Fold the full length of line in the center
and insert the centre fold into one of the slots in the spool middle plate.
4. Wind the upper half of the line tightly
CLOCKWISE
onto the upper spool.
Note: ' CLOCKWISE ' direction when looking at the top of the spool as shown
by the arrow in Fig.4.
Continue winding until approximately 10cm remains at the end of the line and hold
line end by locking into one of the four notches on the top of the spool.
Repeat process with other half of the line winding in the
SAME DIRECTION
on the
lower spool and hold the line end in an opposite notch.
5. Put the spool back into the cover. Remove one end of the line from the spool notch
& push it into an Eyelet slot. Repeat for the other end of the line into the opposing
Eyelet slot. Pull both ends of line tightly through the eyelets to remove any excess
slack in spool winding.
6. Push the spool and cover back into the housing so that the housing clips align with
the cover and clicks back into place.
*
2.4mmø nylon line is recommended to provides best performance. The bump head can
be fitted with line diameters from 2mm to 3mm. The maximum length of the line that
can fit the head varies according to the line diameter. The maximum length capacity
using 2.4mmø is 6 metres. Do not overfill the head spool with excessive lengths of
line as it will result in ineffective spool feeding of line.
