Carburetor Adjustment - Efco DS 2200 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
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.18).
• 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.
