MAINTENANCE
ENGINE OIL REPLACEMENT
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 garbage can, sewer, soil etc.
1. The engine oil replacement is easier if engine is warm
(NOT HOT!).
2. Open the oil tank cap and drain the old oil into an approved
container.
3. Return the engine to an upright position and refill with
lubricant following the instructions in the Adding/Checking
Engine Oil section in this manual.
4. Clean the oil dropped on the unit if necessary.
CLEANING THE AIR FILTER
1. The air filter elements should be cleaned to provide the
engine abundant clean air which benefits the starting,
power and life time of the engine.
2. Remove the air filter cover. To remove, press the Red
button on the top of the cover with thumb and gently push
up the cover with index finger, (see Fig. 15).
3. Remove the air filter (see Fig.16).
4. If only cleaning of the air filter is necessary, take the air
filter pad out and clean it with a jet of dry compressed air
until all dust is removed. Wear protective goggle and
mask to protect your health during this work.
5. 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 place.
NOTE:
Make sure the filter is seated properly inside the cover.
Installing the filter incorrectly will allow dirt to enter the engine,
causing rapid engine wear. If the nylon filter element is lost,
contact customer service for a spare part.
SPARK PLUG
Do not attempt to remove the spark plug from a hot engine.
Clean or replace the spark plug if it is soiled with heavy oil
deposits.
Replace the spark plug if the centre electrode is worn at the
end.
This engine uses either a TORCH CMR5H or
a NGK CMR5H
spark plug with a 0.6-0.8mm electrode gap, (see Fig. 17). Use an
exact replacement and replace annually.
1. Pull out the spark plug cap and clean the dust in the spark
plug area.
2. Screw out the spark plug with the provided socket wrench.
3. Check the ceramic isolation. Replace the spark plug if
damaged.
4. Clean the electrodes (metal tip) to refresh the surfaces.
5. Restore the spark plug and its cap.
