Valve clearance
1. Unplug the engine stop safety line from the emergency stop switch assembly and
remove the spark plug cap from the spark plug.
2. Remove the fuel pump and cylinder head cover.
3. Check the timing belt for slack, aging, or damage. Replace it if necessary.
4. Turn the flywheel clockwise. Align the mark “1" on the driven pulley with the mark
"▼" on the cylinder head.
Check the clearance between intake and exhaust valves of Cylinder 1. Correct it if
necessary.
5. Turn the flywheel 120° clockwise. Align the mark "△" on the driven pulley with the
mark "▼" on the cylinder head.
Check the clearance between intake and exhaust valves of Cylinder 2. Correct it if
necessary.
6. Turn the flywheel 120° clockwise. Align the mark "△" on the driven pulley with the
mark "▼" on the cylinder head.
Check the clearance between intake and exhaust valves of Cylinder 3. Correct it if
necessary.
Note:
It is strictly forbidden to turn the flywheel counterclockwise so as to avoid damage to
the valve system.
Note:
Two places are marked with "△", which are symmetrically arranged on both sides of
the mark "1" and have an 120° included angle with the mark "1".
Adjust the valve clearance when the engine is cold.
7. Loosen the lock nut and rotate the adjusting screw until the specified valve clearance is
reached.
Note:
Turn clockwise the adjusting screw to reduce valve clearance.
Turn counterclockwise the adjusting screw to increase valve clearance.
8. Reinstall the removed parts.
Spark plug
1. Remove the spark plug cap and then remove the spark plug.
