MAINTENANCE
Trimmer head
CAUTION: Always ensure the trimmer cord is wound
tightly and evenly around the drum, otherwise the
machine will generate harmful vibration.
• Only use the recommended trimmer heads and trimmer cords.
These have been tested by the manufacturer to suit a
particular engine size. This is especially important when a fully
57 automatic trimmer head is used. Only use the recommended
cutting attachment. See Recommended cutting attachments
(Page 10).
• Smaller machines generally require small trimmer heads and
vice versa. This is because when clearing using a cord the
engine must throw out the cord radially from the trimmer head
and overcome the resistance of the grass being cleared.
• The length of the cord is also important. A longer cord requires
greater engine power than a shorter cord of the same
diameter.
• Make sure that the cutter on the trimmer guard is intact. This is
used to cut the cord to the correct length.
• To increase the life of the cord it can be soaked in water for a
58
couple of days. This will make the line tougher so that it lasts
longer.
• Only use line of the same diameter as the original to avoid
overloading the engine (Fig.54).
• In order to get more line out of the cutting head, tap it lightly on
the ground while working (Fig.55). NOTE: never hit the nylon
head against hard spots such as concrete or stones, it could be
dangerous.
Replacing the trimmer head
1. Press the tab (Fig.56) and remove the cover and the internal
59
spool.
2. Double back the line, leaving one end 5,5" (14 cm) longer than
the other one. Lock the line in the notch (A, Fig.57). Wind the
line in the direction of the arrow, each end in its chink, regularly,
without crossing them.
3. At the end of the winding, lock in the slits (Fig.58) Assemble the
spring. Slip the line through the eyelet (Fig.59) and pull it
towards the outside. Lock the head with the cover.
