REPLACING THE EDGE-TRIMMING HEAD
LINE
To replace the nylon line, follow the instructions
enclosed with the head (supplementary page
separate from the guide).
Never replace the nylon
line with a line made of any other material
(e.g. metal wire).
DISASSEMBLY (fig. 16)
To block the cutting unit and prevent shaft rota-
tion, fit the steel rod (A) (provided) into the hole
(B) on the upper left side of the head unit, slow-
ly turn the tool until the rod penetrates the hole
of the metal ring nut. Turn the head counter-
clockwise to unscrew the cutting head.
ASSEMBLY (fig. 17)
For safe blocking, the spindle must be prevent-
ed from rotating: fit the steel rod (A) (provided)
into the hole (B) on the left side of the head unit,
turn the tool slowly until the steel rod penetrates
the hole on the metal ring nut, to block tool rota-
tion. Tighten and block the tool without over-
clamping (F).
REMEMBER TO REMOVE
THE ROD AFTER THE CUTTING HEAD HAS
BEEN FITTED AND BLOCKED.
AIR FILTER
Never operate the brush
cutter without the air filter. The air filter must be
kept clean. If damaged or worn fit a new filter.
