Instructions:
Ø 1.Check the oil level with a dipstick.If the oil level is lower than the lower cut line of the dipstick,add lubricating oil to the upper cut line .
Ø 2.Do not increase the load in the cooling machine,must preheat the engine 1 to 3 minutes in advance.
Ø 3.The break-in of the engine is very important.In a new engine within 650miles,the throttle should never be fully open and the gear should be changed at any time.Poor break-in leads to more faults.During break-in,the engine oil should be changed every 185 miles or so;After travelling 210 miles,an adjustment should be made to compensate for the slight wear during the break-in period,so as to ensure the good performance of the engine and extend its service life.For specific break-in requirements,refer to the instructions.
Ø 4.Idle adjustment
(1) Twist the idle screw clockwise completely into place,and then reverse 1 5/8 turn.
(2) Preheat the starting engine to the working temperature,and adjust the idle speed to 1500r/min±100r/min with the fixing screw of the oil door plunger.
(3) Then turn the idle fine-tuning screw to achieve the maximum steady speed of the engine,and then re-adjust the locking screw with the oil door plunger to the specified 1500r/min±100r/min.
Ø 5.Use of electric starting:
It is advisable to use electric starting in neutral.If electric starting is used in other gears,braking must be applied simultaneously.
If the battery power is not enough,just drive a few miles battery after automatic charging,can be used.
