Precaution
- As is shown in the illustration in the summer when you stop the motor to have a rest make sure that the interior packing of plug of the tank is not sub-
merged in fuel. If the air hole is submerged in the fuel the fuel can be lost or filtered due to the larger internal pressure in the tank.
- During the working process and right after you stop the motor do not touch the units of motor especially the muffler.
5. Adjusting the carburetor (Fig.13)
[Note]
Generally it is not necessary to adjust the carburetor because when the motor is out of factory is already in the best position.
If the mixture of fuel is adjusted to an extraordinarily poor level you can soak the motor or increase the minimum number of revolutions per minute which
can cause body injuries when the machine is working.
6. Daily maintenance
Clean the air filter
After cleaning the air filter elements with a special cleaner, use special air filter oil to soak\ it and then dry it thoroughly (Fig. 14).
Check the screw adjuster level
Periodically check the screws to assure that they are duly adjusted, and if they are loosened press them again (Fig.15).
Maintenance
7. Maintenance for every 50 working hours
Clean and adjust the spark plug
Eliminate the rest or sediment of electrode carbon and insulator. Adjust the gap between the electrodes from 0.6 to 0.7mm.
Cleaning the fuel filter
With a steel cable or rope extract the filter from the hole of filled fuel and well clean it with gasoline. If it is very dirty change the fuel filter with a new one
and also clean the fuel tank (Fig. 17).
Eliminate the rest or deposit of carbon
Eliminate the rest or deposit of carbon from the entry and exit hole of the muffler, cylinder and piston. For this task you have to know the motor mainte-
nance technology and dispose the necessary tools. Deliver the machine to the authorised service department to carry out the above operations.
