the new parts immediately. (Fig. 9)
○ 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 HiKOKI 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-
