Technical requirement: 

1. Start  the  main  cable  of  the  motor  (the  thick 

line  in  the  diagram),  the  total  resistance  can  not 

be over 0.0034 ohm. 

2. The maximum voltage drop in coil circuit of 

the starting motor shall not be over 1.0v 

3.  If  the  key  switch  is  in  its  “preheating” 

condition,  contact  points 

①—②⑤

  are  made 

connection,  contact  points 

① — ② ③ ⑤

  are 

made  connection  if  it  is  in  “Run”  condition,

 

and 

contact points 

①—②④

  are made connection if 

it is in “Run” condition, and any contact point is 

not connected if it is in “ OFF” condition. 

4.  Keep  the  cable  as  short  as  possible  during 

layout.   

5. Important suggestions: in order to avoid the 

damage of generator: 

5.1  Never  remove  any  adaptor  if  the  machine 

is not shutdown or the switch is not turn off. 

5.2 Ensure the position prior to dismantling or 

installing adaptor. 

5.3 Never test the current by ignition   

5.4 Confirm correct electrode and voltage.   

5.5 Never install with arc welding   

5.6 The generator can not be run if the storage 

battery is not installed or it is not magnetized.
