the pole pruner to be unmovable for the next operation.

Greasing the guide bar will reduce the problems of premature wear or excessive damage, maintaining the
certain performance, resulting in extension of the service life.

to the guide bar, the grease comes out a
little from the groove of the guide bar. After
