MAINTENANCE
To avoid serious personal injury, always stop the engine
and allow it to cool before cleaning or maintaining the
unit. Never perform cleaning or maintenance while
the unit is running. Disconnect the spark plug wire to
prevent the unit from starting accidentally.
Wear protective clothing and observe all safety
instructions to prevent serious personal injury.
Old engine oil is considered special waste and has
to be disposed according to your local environment
protection regulation. Do not pour the oil into a garbage
can, sewer, soil etc.
The air lter element should be cleaned to provide the
engine abundant clear air which aids in starting, power,
and life time of the engine.
Reinstall the air lter cover by closing the air lter cover
over the button on the housing, then push the cover
until it locks securely in the place.
NOTE: Make sure the lter is seated properly inside the
cover. Incorrect installation will allow dirt to enter the
engine, causing rapid engine wear.
The engine oil replacement is easier if engine is warm
(NOT HOT!).
Use a small brush to clean the outside of the unit. Do
not use strong detergents. Household cleaners that
contain aromatic oils such as pine and lemon, and
solvents such as kerosene, can damage plastic. Wipe
off any moisture with a soft cloth.
Correct and regular cleaning is not only important for
the safe use of this product, but also extends its life
span.
When servicing, use only identical replacement parts.
Use of any other parts could create a hazard or cause
product damage.
