Cleaning the muffl er (Fig. 17)
Remove the muffl er and spark arrestor (if so equipped), and clean
out any excess carbon from the exhaust port or muffl er inlet every
100 hours of operation.
For long-term storage
Drain all fuel from the fuel tank. Start and let engine run until it
stops. Repair any damage which has resulted from use. Clean the
unit with a clean rag, or high pressure air hose. Put a few drops of
two-cycle engine oil into the cylinder through the spark plug hole,
and spin the engine over several times to distribute oil. Cover the
unit and store it in a dry area.

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
HiKOKI Authorized Service Center.
Symptom
Tool Does not operate.
The tool does not trim well.
Possible cause
Foreign matter is lodged in the blade.
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.
Weekly maintenance
○ Check the starter, especially cord and return spring.
○ Clean the exterior of the spark plug.
○ Remove it and check the electrode gap. Adjust it to 0.6 mm, or
change the spark plug.
○ Clean the cooling fi ns on the cylinder and check that the air
intake at the starter is not clogged.
○ Check gear case is fi lled with grease.
○ Clean the air fi lter.
Monthly maintenance
○ Rinse the fuel tank with gasoline.
○ Clean the exterior of the carburetor and the space around it.
○ Clean the fan and the space around it.
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.
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.
