or other damage.
○ Check the case and button for wear.
○ The cutting head must be securely mounted to the unit's
gear case/cutter case.
○ 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.

Install cutting head on gear case/cutter case of grass
trimmers/brush cutters. The mounting nut is left-hand-

Since the cutter holder cap is not used here, keep it for
when a metal blade is used, if so equipped.
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. 10)

○ If your unit is of a nut securing type and equipped with a
cotter pin, the blade must be retained with a new pin (20)
each time installed. (Fig. 13)
NOTE
When installing or removing a blade, make sure to wear
gloves and place the blade cover over the blade.
