Bevel Gear; Guard - Efco D - BC Manual De Instrucciones

• 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
en
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 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.11).
• In order to get more line out of the cutting
head, tap it lightly on the ground while
working. NOTE: never hit the nylon head
against hard spots such as concrete or
stones, it could be dangerous.
Replacing the nylon line on the LOAD&GO
trimmer head (Fig. 12)
Ø 4.3 in / 110 mm: cut 13 ft (4 m) of nylon line
Ø 0.09 in (2.4 mm).
1. Align the arrows and insert the line into the
trimmer head (Fig. 12.1) until it is released
from the opposite side (Fig. 12.2).
2. Divide the line into two equal parts (Fig.
12.3) and then load the trimmer head by
turning the knob (Fig. 12.4).
