LUBRICATING BLADE
1. For easier operation and longer blade life, lubricate
the hedge trimmer attachment blade before and after
each use. Before lubricating, be sure the switch is in
the OFF position on the powerhead. Apply light
machine oil along the edge of the top strap (Fig. 15).
2. Occasionally, you should oil your hedge trimmer
attachment during use. Before oiling, stop hedge
trimmer, then oil. You then can resume trimming. Do
not oil while hedge trimmer attachment is running.
NOTE: Avoid using solvents when cleaning plastic parts.
Most plastics are susceptible to damage from
various types of commercial solvents, and may
be damaged by their use. Use clean cloths to
remove dirt, carbon dust, etc.
