Spark plug
Replacement
1) Remove the dust on the cylinder head around spark plug.
2) Cut the high damping line of spark plugs. Note you only can pull the spark plugs cover.
3) Use spark plug wrench, loosen spark plugs and then remove it.
4)
Install new spark plugs
Notes:
Ensure the new spark plugs comply with the required heating degree and size.
6) Tighten torque spark plugs.
Tighten the spark plug with the rated tightening torque:

7) While connecting the spark plug high damping lines, please don’t push the
high-voltage wire, just push the shield.
Ignition system circuit (high damping line)
Check
Check whether there’re cracks of the high damping line and the resistance of the
joints; Resistance data and the measurement steps as per section 7 in chapter 3.
Changed when it’s damaged.
Notice:
Do inspection to ensure that every high damping line and resistance are already firmly connected, and insert
into the complementary components totally. Change every burnout joint.
1) Disconnect the damping line and the ignition coil.
2) Link with new damping line and clip it tightly. Don’t pull the damping line joint but only pull the cover.
Ignition time
Check
Use fault decoder to check and be sure whether the ignition time is appropriate while it is rotating. If it can not
meet the requirement, please check the valve timing or electronic control system.

Fuel
Engine idle speed and exhaust gas mixture
Check
Check engine idle speed and exhaust gas mixture. Adjust it when it’s necessary. Detail requirements for checking
idle speed/ gas mixture please as per chapter 3.
Fuel tank cover
Inspection
Measure the gasket of fuel case, please change it if damaged.
Caution:
The new cover should be the same in order to avoid
working inappropriately.
Air filter core
Replacement
Caution:
Under dusty conditions, change it more frequently. Ask the local service providers for more details
about the change of the core. Please as per section 5 in chapter 3 for the steps of the changing the air
cleaner core.
Check and cleanness
1) Visually check air filter whether it is over dirty, damaged or contains too much oil.
2) Clean filter core through the air filter by compressing the air.
