c. Adjust the bend to become between 10 to 15 mm when push center or V-belt, witch clutch cable fitting. (3)
d. Move the shift lever to neutral position and start engine.
After adjusting the tension of the V-belt, check to see that the transmission pulley stops completely when the clutch
lever is released.
If the transmission pulley does not stop quickly, align the belt guide and readjust the clutch cable.

2) DIFFERENTIAL WIRE ADJUSTMENT
a. Adjust the load weight to become 24,5 to 29N (2,5 to 3,0 kgf) when the differential lever is ON with differential fitting.
Check to see that the differential is locked when move the differential lever to ON.
3) TINE REPLACEMENT
REMARKS :Stop the engine, shift to neutral and remove spark plug wire before cleaning out the tines by hand.
A badly worn Tine causes your tiller to work harder and dig shallower.
Most important, worn tines cannot chop and shred organic matter as effectively, nor bury it as deeply, as good tines.
A worn tine needs to be replaced.
To maintain the quperb tilling performance of this machine, the tines should be checked for sharpness, wear and
bending, particularly the two cleaning tines which are next to the tine transmission.
If a cleaning tine has been broken or bent outward by harsh usage in the rough field, the auto stake (resistance stake)
can become clogged with grass or mud during SRT operation. If can lower cultivating efficiency.

4) COOLING SYSTEM
Your engine is air-cooled. For proper engine performance and longer life, keep your engine clean.
When the air inlet at the recoil starter or the cooling fin is clogged with grass or dust, the engine will overheat.
5) SPARK PLUG
1. The spark plug should be checked at the beginning of every tilling season.
2. Set the gap at 0,7 mm and reinstall.
In case the grap becomes bigger than 0,7 mm and exhausted, it should be replaced.
3. Make sure spark plug wire is firmly attached to spark plug.
6) ENGINE LUBRICATION
1. When changing oil, stop the engine and loosen the drain plug.
2. Re-install the drain plug before refilling oil.
