Cleaning the cutting device (hedge trimmer)
> Keep the cutting device (B6) clean and free of debris. Remove trimmings.
> Keep the cutter blade (B7) sharp to retain a good cutting performance. Replace a
worn or damaged cutting device (B6) with a new one of the same type.
> Lubricate the cutting device (B6) after each use to prolong the life span of the
machine. Apply light machine oil along the edge of the cutter blade (B7) (Fig. 56).
> Check it for any damage and protect it from corrosion. If necessary take the cutter
blades to an authorized dealer for sharpening.
> Tighten loose nuts on the cutting device (B6) with a proper wrench to ensure safe
operation (Fig. 57).

Guide bar (pole pruner)
Most guide bar (C6) problems can be
prevented merely by keeping the machine
well maintained. Incorrect filling and non-
standard cutter and depth gauge settings
are the causes of most guide bar problems,
primarily resulting in uneven bar wear. As
the bar wears unevenly, the rails widen,
which may cause the chain to clatter and
make it difficult to complete straight cuts.
If the guide bar is insufficiently lubricated
and the machine is operated with a saw
chain which is too tight, this will contribute
to rapid bar wear. To help minimise bar wear,
maintenance of the guide bar as well as the saw chain is recommended.
> Disassemble the guide bar (C6) and saw chain (C7) in reversed order from assembly.
> Check the oil dispenser for clogging and clean if necessary to ensure proper
lubrication of the guide bar and saw chain during operation. Use a soft wire small
enough to insert into the oil dispenser (Fig. 58).
