REPLACE ENGINE OIL
WARNING:
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 engine oil replacement is easier if engine is warm
(NOT HOT!).
1. Open the oil tank cap and drain the old oil to an
approved container.
2. Return the engine to an upright position and refill with
lubricant following the instructions in the ADDING/
CHECKING ENGINE OIL section in this manual.
3. Clean the oil dropped on the unit if necessary.
CLEAN AIR FILTER
The air filter element should be cleaned to provide the
engine abundant clear air which aids in starting, power,
and life time of the engine.
1. Remove the air filter cover. To remove, press the
green button on the top of the cover with thumb and
gently push up the cover with index finger.
2. Remove the air filter.
3. If only cleaning of the air filter is necessary, take the
air filter pad out and clean it with dry compressed air
until all dust is removed. Wear protective goggles and
mask to protect your health during this procedure.
Reinstall the air filter cover by closing the air filter cover
over the button on the housing, then push the cover
until it locks securely in the place.
NOTE: Make sure the filter is seated properly inside the
cover. Incorrect installation will allow dirt to enter the
engine, causing rapid engine wear.
