Safety information about inspection and maintenance:

DANGER

CAUTION: To avoid touching the battery electrolyte.

The electrolyte contains diluted sulphuric acid, which can cause blindness 

and burn if eyes or skin contacted with it. If electrolyte splash into your eyes, 

flush thoroughly with water immediately and call a physician.

WARNING

CAUTION: To avoid short circuit to prevent from fire.

Do not confuse the earth terminals while checking electric system; 

otherwise the fire will result from short circuit.

WARNING

CAUTION: To avoid being caught into the rotary parts.

Be sure to carry out maintenance with the engine stopped.

Do not remove the cover of rotary parts.

CAUTION

Do not rebuild product without permission.

Do not release the control the high-speed limiting screw and oil level 

limiting bolt, otherwise the engine life will be shortened. Any rebuilding or 

disassembling of the engine will decrease safety even cause severe 

accident. If necessary, contact your local KAMA agents for replacing the 

genuine parts or technical support.

9.10 Engine oil consumption is over large

6. There is oil leakage in the air valve seal

6. Replace the air valve seal

The cause of the fault

1. The engine oil viscosity is too low, and
its brand isn't proper

2. The gap between piston and cylinder
 is too large, and the oil hole in the piston
circle groove is clogged. 

3. The piston ring is clogged circuit groove 
or the installation position of the

4. There isoil leakage in the front seal and
rear seal of the crankcase

5. The engine oil temperature and
pressure is excessive

Elimination method

1. Replace the engine oil brand

2. Clean or replace the oil hole

3. Clean, repair or replace

4. Check and replace the relative parts

5. Decrease the temperature, check and
regulate the pressure-limited valve

9.11 There is abnormal sound when running the engine

9.The oil injector assembly is snapped

9. Clean or replace the nozzle assembly

The cause of the fault

1. The gap between piston and cylinder
is too large

2. The gap between piston pin and small-
end bush of connecting rod is too large

3. The gap between main bush and the
connecting rod bush is too large

4  The gap between the piston ring and
piston ring circuit groove is too large

5. The gap between pressure surface 
and thrust piece is too large

6.The piston bumps into the air valve

7. The abrasion of the gears is serious, 
and the gap between the gears is 
excessively large. There is a clash bump 
when reducing the speed suddenly

8. The timing of oil supply is too early

Elimination method

1. Replace the piston ring, piston, and
bore the cylinder if necessary.

2. Repalce the worn parts, keep the 
specified gap

3. Replace main bush, connecting rod
bush, keep the radial gap specified

4. Replace the piston ring, and replace 
the piston if necessary

5. Replace the thrust piece, and keep the
specified gap

6. Check the clearance height 

7. Judge whether replace the gear or not
according to the abrasion degree

8. Check and regulate the timing of oil supply
