5. Re-install the repair cover and screw the screw.

Maintenance of the spark plug

Recommended spark plug: A7RC or NGK R7HSA
To ensure the engine to work in good order, the clearance of the spark plug must be correct, and
has no accumulated charcoal.
1. Dismantle the repair cover of the spark
plug (Fig. Z).
2. Dismantle the cap of the spark plug.
3. Clean out the filth around the base of the
spark plug.
4. Dismantle the spark plug with a spanner.

D – Cap of the spark plug (Fig. AA)
5. Examine the spark plug with your naked eyes. If the insulator has crazed or has fragments,
you should discard the spark plug. If the old spark plug needs to be used continually, you
must clean it up with a brush.
6. Measure the clearance of the spark plug with a gauge. The clearance should be 0.6nm to
0.7nm. (Fig. AB)
7. Install the spark plug carefully by hand. Pay attention not to overlap the screw thread.
8. After installing a new spark plug by hand, screw it with a spanner for a half circle in order to
press the washer tightly. If an old spark plug is installed, you only need to screw it from one
eighth circle to one fourth circle after it is fixed.
9. Re-install the cap of the spark plug.

2.9 TRANSPORT / STORAGE

In order to avoid the generator leaking oil during transport or temporary storage, make sure to
switch off the generator, keeping it at a standing pose under normal operations. After the engine
is totally cooled, turn the ventilating pole of the fuel-filling lid to the "close" position thoroughly.
When transporting the generator:
Do not let the fuel spill out of the fuel tank. (The top of the fuel-filling tank should have no
fuel.)
A T T E N T I O N
The spark plug must be fixed
firmly, or else it will become
very hot and damage the gen-
erator.
Do not use the spark plug whose
thermal measurement range is not
suitable.
