TROUBLESHOOTING
Use the inspections in the table below if the tool does not operate normally. If this does not remedy the problem, consult your dealer or the
Tanaka dealer.
Symptom
Possible cause
Remedy
Tool
Does not operate.
Foreign matter is lodged in the blade.
When there is foreign matter in the blade, use a
pair of tongs or similar tool to remove it.
Take great care since the tool may start
operating when the foreign matter has been
removed.
Sap or rust may also prevent the blade from
operating. Use a wire brush or similar tool to
remove sap or rust.
The tool does not trim well. The blade stopped because it was used to cut
a branch whose width exceeded the blade’s
cutting capacity.
NOTE
Work that will repeatedly cause the blade to
stop will eventually damage the tool.
Some garden trees have wood that is very
hard and may be beyond the capacity of the
tool even if it is of a width that is within normal
capacity. Use a pair of pruning shear to remove
thick branches before starting work.
An oblique cut may also exceed the capacity of
the tool since the length of the cut increases.
Be sure to trim thick branches at right angles.
