3. Check the engine oil level and top up if required. Use proper engine oil with the proper
viscosity (SAE 10W-30 is recommended).

fuel may damage the fuel system.
5. Check for oil and fuel leaks.
Start and Stop Procedure
1. Open the fuel cock.
2. Turn the STOP SWITCH to the position ‘I’ (ON)
3. Set the speed control lever 1/3 of the way towards the high speed position.
4. Close the choke lever.
If the engine is cold or the ambient temperature is low, close the choke lever fully.
If the engine is warm or the ambient temperature is high, open the choke lever half way, or
keep it fully open.
5. Pull the starter handle slowly until resistance is felt. This is the
‘compression’
point. Return the
handle to its original position and pull swiftly. Do not pull out the rope all the way. After starting
the engine, allow the starter handle to return to its original position while still holding the
handle.
6. After starting the engine, gradually open the choke by turning the choke lever and finally keep
it fully opened. Do not fully open the choke lever immediately when the engine is cold or the
ambient temperature is low, because the engine may stop.
7. To stop the engine, Set the speed control lever at the low speed position and allow the engine
to run at low speed for 1 to 2 minutes before stopping.
8. Turn the STOP SWITCH counter-clockwise to the position ‘0’ (OFF)
9. Close the fuel cock.
10. Pull the starter handle slowly and return the handle to its original position when resistance is
felt. This operation is necessary to prevent outside moist air from intruding into the combustion
chamber.
