AIR FILTER CLEANING
NOTICE: Do not operate the engine without an air cleaner
element as this will cause damage to the inner parts of
the engine. In unusually dusty condions regular cleaning
or replacing is required.
The foam lter element of the dirty air lter will restrict the air
ow to the fuel system and reduce the engine performance.
If the generator is used in a dusty area, the maintenance
frequency of the air lter’s foam lter element is higher than
that in the maintenance requirements.
1. Wash the lter element in warm soapy water and let it dry
naturally, or clean and dry it in a non – ammable solvent.
2. Dip the lter element into clean oil and squeeze out excess
oil. If there is too much oil le in the lter element, start
the engine and the engine will smoke.
3. Use a damp cloth to remove dirt from the inside of the air
lter’s cover. Take care to prevent dust from entering the
air ducts which leads to the fuel system.
Spark Arrester
The spark arrester must be cleaned every 100 hours to
maintain engine performance. Ensure exhaust outlet and
engine is cold before cleaning and maintenance.
To remove and clean the spark arrester.
1. Loosen two M5x12 pan head bolts and remove mounng
cover, muer mesh cover and spark collector.
2. Clean the muer’s mesh cover and the cumulave carbon
on the spark collector with a steel wire brush.
3. Ret and ghten the spark arrester.
NOTICE: Clean with steel wire brush gently to avoid
damage or scratch to muer mesh and spark arrester.
The spark arrester must not be broken or cracked. If it is
damaged, it must be replaced.
Spark Plug
NOTICE: Incorrect spark plug can cause damage to the
engine.
To replace or clean the spark plug use the spark plug spanner
kit supplied. Allow engine to cool before aempng to
remove the spark plug.
1. Rotate the lock 90° counterclockwise, and open le
maintenance door.
2. Loosen bolt of spark plug’s maintenance cover and remove.
3. Remove the spark plug cap, remove dirt and dust from
around the spark plug.
4. Use the spark plug spanner and rotate counter-clockwise
and remove the spark plug.
5. Check the spark plugs. Replace the spark plug,
if the electrode is worn or burnt, or if the
insulator is cracked or broken. Standard spark
plug: NGK BPR7ES, clearance of spark plug:
0.6-0.8mm.
6. Aer ensuring that the spark plug is in good
condion, x the spark plug gently to the
head of the cylinder by hand to prevent
thread damage caused by force.
7. Aer the spark plug is xed, ghten it with the
spark plug spanner. If the used spark plug is to
be reinstalled, ghten 1/8-1/4 circle manually
aer xing the spark plug and before
ghtening it to the specied posion. If the newly installed
spark plug is to be reinstalled, ghten 1/2 circle manually
aer xing the spark plug and before ghtening it to the
specied posion. Torque: 13.3 LBS. Ft (18 N.M, 1.8kg.m)
8. Install the spark plug cap.
9. Install spark plug maintenance cover and ghten
maintenance cover’s bolts.
10. Close the le maintenance door, and rotate the lock 90°
clockwise.
NOTE: Spark Plug Type: NGK BPR7ES
NOTE: If the spark plug is installed without torque wrench, a
beer esmaon method is to ghten 1/4-1/2 circle
manually, but the spark plug should be ghtened to the
specied torque.
