USING THE GENERATOR

1. Service Environment of the Generator

   • Applicable temperature: -5°C~ 40°C;

   • Applicable humidity: below 95%;

   • Applicable altitude: regions below 1,500 m (It shall be used by reducing power in regions above 1,000 m). Standard atmospheric condition

   • Ambient temperature Tr: 298k (25°C)

   • Relative air humidity Фr: 30%

   • Absolute atmospheric pressure Pr: 100kPa
     When actual environmental condition is inconsistent with the condition of output power of the generator set:

   • Every 5°C of increase in ambient temperature will reduce the power of generator by about 2%.

   • Every 30% of increase in relative humidity of air will reduce the power of generator by about 1.5%.

   • Every 300 m rising of ASL will reduce the power the generator by about 4.5%.

2. Generator Wiring

   • When the generator is connected to household power source as a backup power supply, the connection shall be
     carried out by a professional electrician or a person familiar with electricity.

   • After connecting the load to the generator, check carefully whether electrical connection is safe and reliable.
     Improper electrical connection may cause generator damage, burning or fire.

   • Avoid connecting this generator to commercial power outlet.

   • When extending the cable, be sure not to exceed its length.

   1. 60m cross-section area is 1.5mm²
   2. 100m cross-section area is 2.5mm²

   • The appearance of extension cable shall be protected by a layer of tough and elastic rubber cover (IEC25) or
     other substitutes.
     
     Connection of AC power
     WARNING

• These items shall be  replaced if necessary;
• These items shall be maintained by the dealer authorized by the Company, unless the user has proper tools and maintenance ability.

ATTENTION

• If it often works under high temperature or high load, oil shall be changed every 25 hours;
• If it often works in dusty or harsh environment, air cleaner element shall be cleaned every 10 hours. If necessary, the air cleaner element shall be replaced every 25 hours;
• It shall be maintained on spot-inspection cycle and time, whichever is earlier;
• If maintenance cycle time has elapsed, perform the maintenance as soon as possible as per the table above.

WARNING

Please shut down the engine first before performing any maintenance. The engine shall be placed in a horizontal position. In order to prevent the engine from starting up, separate spark plug cap shall be separated from spark plug.

Do not use it indoors or use it in a tunnel, cave or other places ventilated poorly. Make sure that work area is well ventilated. Exhaust gas from the engine contains toxic gases, carbon oxides, and the inhalation can cause shock, loss of consciousness, and even death.

1. Spark Plug Inspection

5. Check the model of spark plug and clearance.
   Spark plug gap: 0.7-0.8mm
   Standard spark:
   BRAND| MODEL
   ---|---
   NGK| C7HSA
   CR6HSA
   TORCH| A5RTC

Tip : The spark plug clearance is required to be measured by line thickness gauge, which shall be adjusted if
necessary.
