Muffler Filter (ZX50U-5N, 60USB-5N)

The muffler filter removes particle matters (PM) from the
exhaust gas. The muffler filter traps PM, and it is automatically
regenerated by burning PM when a set amount of PM is
accumulated in the filter. Follow the instructions below to
prevent the muffler filter from being damaged.

WARNING:
 Exhaust gas from the muffler filter, exhaust piping
and tail piping becomes hot during and right after
engine running and filter regeneration (burning PM).
Be careful not to let your skin contact any part of
exhaust system or hot gas from the exhaust piping.
 If flammable materials such as dead leaves or paper
scraps are around the muffler, they may cause a fire.
 Before maintaining the machine, stop the engine
and make sure the engine has sufficiently cooled
down in order to prevent burns.
IMPORTANT:
 Be sure to use fuel that complies with JIS K-2204,
EN-590 or ASTM D-975 which contents 15 ppm or
lower sulfur. If the fuel described above is not used,
exhaust gas that exceeds the regulation values may
be discharged and serious problems may arise on the
engine.
 Use only genuine Hitachi or oil manufacture's
engine oil. Using engine oil other than the genuine
Hitachi or oil manufacturer may shorten the muffler
cleaning interval and increase the fuel consumption
rate.
 Besides, using bad quality fuel, drainage agent, fuel
additives, gasoline, kerosene or alcohol refueled
or mixed with specified fuel may deteriorate
performance of fuel filters and cause sliding problem
at lubricated contacts in the injector. It also affects
the engine parts, leading to malfunction.
