○ Install cutting head on gear case of grass trimmers/brush
cutters. The mounting nut is left-hand-threaded. Turn clockwise
to loosen/counterclockwise to tighten.
For curved shaft models, the mounting nut is right-hand-threaded.
Turn counterclockwise to loosen/clockwise to tighten.
NOTE
○ Since the cutter holder cap is not used here, keep it for when a
metal blade is used, if so equipped.
○ Insert Allen wrench (19) into the hole of the gear case in order to
lock the cutter holder.
4. Adjusting line length
○ Set the engine speed as low as possible and tap the head on
the ground. The nylon line will be drawn out about 3 cm with
each tap. (Fig. 16)
Also, you can extend the nylon line by hand but the engine must
be completely stopped. (Fig. 17)
○ Adjust the nylon line to the proper length of 11–14 cm before
each operation.
Installation of cutting blade (Fig. 18)
(If so equipped)
When installing a cutting blade, make sure that there are no cracks
or any damage in it and that the cutting edges are facing the correct
direction.
NOTE
○ When installing cutter holder cap (20), be sure to set concave
side upward.
○ Insert the alien wrench (19) into the hole of the angle
transmission in order to lock the cutter holder (21). Please note
that the cutter fi xing bolt or nut (22) has left-handed threads,
(clockwise to loosen/ counter-clockwise to tighten). Tighten the
fi xing bolt or nut with the box wrench.
○ If your unit is of a nut securing type and equipped with a cotter
pin, the blade must be retained with a new pin (23) each time
installed. (Fig. 19)
CAUTION
○ Before operation, make sure the blade has been properly
installed.
○ If your unit is equipped with protection cover under a cutting
blade, check it for wear or cracks before operation. If any damage
or wear is found, replace it, as it is an article of consumption.
