Stihl FS 56 Serie Manual De Instrucciones página 15

STIHL PolyCut mowing head
Uses either nylon lines or nonrigid,
pivoting polymer blades.
Observe wear indicators.
WARNING
Three rectangular wear limit marks are
applied to the base (periphery) of the
PolyCut. To reduce the risk of serious
injury to the operator or bystanders from
breakage of the head or blades, the
PolyCut must not be used when it has
worn as far as one of these marks. It is
important to follow the maintenance
instructions supplied with the head.
WARNING
To reduce the risk of accidents from
shattered blades, avoid contact with
stones, metal and similar solid objects.
Check PolyCut blades for cracks at
regular intervals. If a crack is found on
one blade, always replace all blades.
STIHL FixCut mowing head
Uses pre-cut lengths of nylon line.
Observe wear indicators.
FS 56, FS 56 R, FS 56 C, FS 56 RC
Do not continue using the mowing head
if the raised moldings (1) on the base
are missing or worn – see right
illustration above. The mowing head
may otherwise shatter and flying objects
could result in injury to the operator or
bystanders. Install a new mowing head.
Risk of Kickout (Blade Thrust) with All
Rigid Cutting Blades
WARNING
Kickout (blade thrust) is
the sudden and uncon-
trolled motion towards
the operator's right or
rear that can occur when
the shaded area (espe-
cially the darkly shaded
area) of a rotating blade
comes in contact with a
solid rigid object like a
tree, rock, bush or wall.
The rapid counterclock-
wise rotation of the blade
may be stopped or
slowed, and the cutting
attachment may be
thrown to the right or to
the rear.
This kickout (blade thrust) may cause
loss of control of the power tool and may
result in serious or fatal injury to the
operator or bystanders. To reduce the
risk of injury, extreme caution should be
used when cutting with the shaded area
of any rigid blade.
