• Before inspecting, cleaning, or servicing the tool, turn off the engine, wait for all moving parts to stop; disconnect the
spark plug cord and separate it from the spark plug. Otherwise, you may suffer serious injuries due to accidental
equipment start.
General cleaning
• Use a brush or compressed air to clean and clear the
ventilation slots of the starter unit whenever necessary.
• Periodically clean the engine cylinder fins and fan fins to
remove any impurities. Failure to do so may cause the
engine to overheat.
Air filter cleaning
• Remove the air filter cover by loosening the cover screw.
• Remove the air filter.
• Depending on usage time, you can give the filter a
superficial cleaning by tapping it lightly on a smooth, flat
surface to dislodge most particles.
• Alternatively, blow the filter with compressed air from
both sides.
• For a more thorough cleaning, wash the air filter in
warm soapy water, rinse it, and let it dry completely
before reinstalling it in.
• Reinstall the air filter, ensuring it fits securely in place.
• Clean the air filter as often as needed to keep it
consistently clean; otherwise, the engine's efficiency may
decrease.
Fuel filter
• Regularly check the gasoline filter.
• If the filter is dirty, it should be replaced.
• If the inside of the gasoline tank is dirty, rinse it with
gasoline.
Carburetor adjustment
• It is recommended to have carburetor adjustments done
at a
Authorized Service Center.
• Incorrect adjustment can damage the engine and void
the warranty.
Tool storage
If you plan to store the tool for a month or more, consider the following:
• Drain all fuel from the fuel tank into an approved gasoline container. Any excess should be reused in another two-stroke
engine equipment with a 50:1 ratio.
• Run the engine until it consumes the remaining fuel and shuts off on its own to eliminate residual fuel and prevent the
formation of clumps that could damage the fuel system.
• Clean the tool thoroughly.
• Store the unit in a ventilated space, away from corrosive agents such as garden chemicals or ice-melting salts, and out of
reach of children.
• Comply with all government safety regulations for handling and storing fuels.

Maintenance
Spark plug replacement
• The engine uses a Champion RCJ-6Y spark plug with an
electrode gap of 0.63 mm (0.025"). Replace the spark
plug with an identical new one once a year.
• With the engine completely cold, loosen the worn spark
plug to the left with a wrench and remove it.
• Insert the new spark plug and hand-tighten it to the
right.
CAUTION
• Be careful not to damage the spark
plug thread; otherwise, serious damage to the engine
may occur.
Exhaust and muffler cleaning
• The exhaust and muffler may become clogged with
carbon deposits, depending on the type of fuel, amount
of oil used, and/or usage conditions. If you notice a loss
of power, these deposits should be removed to restore
performance. Visit a
Center to perform this service.
• The muffler is equipped with a spark arrester screen
inside. After extended use, the screen becomes dirty and
the muffler should be replaced. Visit a
thorized Service Center to perform the replacement.
CAUTION
• Continuously check that the muffler is
properly secured with fasteners and that there is no
damage or corrosion. If a leak is found, stop the tool and
immediately take it to a
Service Center for repair.
Lubrication
• The inside of the gearbox is lubricated with
multi-purpose lithium-based grease. Visit a
Authorized Service Center to replace the grease every 50
hours of use.
• Insert the new grease through the grease valves located
in the gearbox.
