○ For outstanding performance and reliability, always use Hitachi
nylon cutting line. Never use wire or other materials that could
become a dangerous projectile.
○ If the cutting head does not feed cutting line properly, check
that the nylon line and all components are properly installed.
Contact Hitachi Authorized Service Centers if you need
assistance.

metal blade is used, if so equipped.
○ Press the stopper pin (20) 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. 15)
Also, you can extend the nylon line by hand but the engine must
be completely stopped. (Fig. 16)
○ Adjust the nylon line to the proper length of 11–14 cm before
each operation.
Installation of cutting blade (Fig. 17)
(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 (21), be sure to set concave
side upward.
○ Press the stopper pin (20) of the angle transmission in order
to lock the cutter holder (22). Please note that the cutter fi xing
bolt or nut (23) has left-handed threads, (clockwise to loosen/
counter-clockwise to tighten). Tighten the fi xing bolt or nut with
the box wrench.
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.
○ You have to wear gloves when handling the cutting blade.
WARNING
For Hitachi heads, use only fl exible, non-metallic line
recommended by the manufacturer. Never use wire or wire
