1.2 ,Maintenance of air filter
Timely cleaning and maintenance of air filter can effectively prolong the service life of gasoline engines. Please replace the damaged air filters in time. Remove the air filter cover, take out the filter element, wash the filter element in soapy water, and rinse it clean. After drying, add two drops of oil to increase the air filtration effect,and install it back in proper order.
Warning: Prohibit starting a gasoline engine without air filter!
1.3, Inspection of ignition system
Check the spark plug regularly. Spark plug’s contact spacing is 0.6mm-0.7mm, clean up the carbon deposition between contacts In time.
1.4, Cleaning of cylinder cooling sink
The cylinder cooling sink is the main way of cooling down the gasoline engine in operation. Timely cleaning can effectively prevent the cylinder from being damaged due to overheating.
2, Belt maintenance Please check the tightness of the belt regularly and adjust the tightness of the belt in time. (see the right picture) –Loosen the fixed bolts(1) –Loosen the nut, turn the screw stem (2),
adjust the tension by turning left and right. –Ditto, release the tension pulley and you can easily change the belt. Remind, please tighten the belt properly, if the belt is too tight,it will shorten the usage life. Tips: Belt tightness can be measured on the double fingers press inward in a range of 2cm or so.
2, Other maintenance Before storing the machine for a long time, please lubricate the bearing and clean the rotor and knife box, then make the anti-rust protection for the rotor and knives.
