Maintenance and care
Method to change shield (Consult your dealer.)
There are two types of shields: namely one used exclusively for
nylon line cutting head and another one used exclusively for met-
al blade. When using nylon line cutting head, use the shield for
nylon line cutting head.
Remove bolt (M5×18) on the right side of the shield and slide the
shield to the left and remove it. Put shield of another type into
groove and slide it to the right until it stops and be sure to fasten
with the removed bolt (M5×18).
Fit cut off knife to the shield for nylon line cutting head using
screw (5×12).
Installing nylon line cutting head
Use only flexible, non-metallic line recommended by
YAMABIKO CORPORATION.
Fasten output shaft using locking tool securely in order
to avoid the possibility of output shaft rotating when
mounting nylon line cutting head.
Insert locking tool into a hole located on the right side of angle
transmission while forcing retainer spring to the left side. Insert
locking tool further into blade retainer fixing slot to fix output shaft.
Thread nylon line cutting head onto shaft (anticlockwise) until it is
tight.
