2. Fuel System - Fuel Vapors are highly explosive and can cause severe injury or death. Use extreme care when handling and storing fuels. Store fuels in a well-ventilated area away from spark-producing equipment, gas hot water heaters and out of the reach of children. Never add fuel while the engine is running or hot, fuel spills may ignite on contact with hot parts and mufer. Do not operate under the inuence of drugs and alcohol or smoke. when operating around sparks or open ames. Keep fuel lines and connections tight and in good working condition.
3. Servicing the exhaust system. Hot parts can cause severe injury. Do not touch hot engine parts. The engine and exhaust system components become extremely hot during operation.
4. Servicing the engine. Hot parts can cause personal injury or property damage. Keep the generator at least 2m (6ft) distance from other devices.
5. Grounding electrical equipment. Hazardous voltage can cause severe injury or death. Electrocution is possible whenever electricity is present. Ensure you comply with all applicable state and local codes and standards. Electrically ground the generator set, transfer switch, and related equipment and electrical circuits. Turn off the main circuit breakers of all power sources before servicing the equipment. Never contact electrical leads or appliances when standing in water or on wet ground because these conditions increase the risk of electrocution. It is highly recommended that a barrier exists between you and the ground surface at all times. We recommend using a wooden pallet with rubber mat on top to stand on while working or servicing the standby generator. Grounding is required of all AC circuits, use terminal (identify terminal) for bonding this circuit to the enclosure with a grounding rod (Not provided with unit). Ground the enclosure to a grounding electrode in accordance with state and local code requirements.

Operating System Functions and Denitions
Power Switch: The power switch controls the entire generator set control system. If this switch is placed in the OFF (O push in down mode) position, the internal electrical control circuit of the unit will not have electrical power. When this switch is placed in the ON (I in the up mode) position, the control system can be manually or automatically started with ATS.
Fuel switch: The fuel switch allows the fuel to ow to the engine when placed in the ON or ( I ) is in the up position. Likewise, the switch turns the ow of fuel off to the engine when placed in the OFF (O) push down position.
Emergency stop switch: If an emergency situation occurs, immediately press the Emergency Stop Switch located on the right outside corner of the standby cabinet. The unit will automatically shut down. Once the switch has been depressed and the emergency situation has passed, to re-start the generator unit, rotate clockwise 15° to pop out into the normal operating position. When depressed, all generator control systems will immediately shut down, including the engine and generator head. The Emergency Stop Switch should be pressed immediately should any unexpected emergencies occur. Depressing this button will help minimize dangerous damage to persons, pets, property, plants, or to the generator unit itself.
Primary Circuit Breaker (located on main control panel under generator lid): The primary circuit breaker controls the ON/OFF functions of the generators electrical power output. When this switch is in the up (ON) position, electrical power output will be produced and ow normally. When this switch is placed in the down (OFF) position, electrical power output will be broken, or turned off. However, as a safety function, when this switch is placed in the ON position, the production of a too large of an electrical load or a short circuit due to faulty operation, the switch will immediately and automatically switch to the OFF position in order to protect the generator from damage. Should this occur, turn off the generator unit and correct the cause before restarting and placing the circuit breaker in the ON position.
Use: When starting manually, always start the generator before placing the main circuit breaker in the ON position. Likewise, when operating manually, place the circuit breaker in the OFF position before shutting the generator down.

2. Cooling System
Use only automotive grade antifreeze and distilled water in cooling system. Do not use water that contains salt or alkalis (Tap Water)! Using non-distilled water creates scale in the radiator, causing corrosion and premature wear.
You must check and maintain all fuel, lubricant and coolant levels. Not doing so will accelerate and shorten the life of the standby system. Attention must be paid to all uid systems and annually serviced by an authorized
service provider or call 844-367-5660 for assistance.
Converting from Natural Gas (NG) to Liquid Propane Gas (LPG)
Most generators are congured for natural gas operation at the factory. Switching over to LP Vapor is a simple
procedure.
3. Fuel Conversion
Do not touch hot engine parts. The engine and exhaust system components become extremely hot during operation.
Two fuel connections on the fuel block allow eld conversion between natural gas (NG) and Liquid Propane (LPG). The fuel metering valves are factory-set and sealed to provide the best possible hot and cold starting.
Use the following procedure to convert fuel from type to another. Natural Gas (NG) and Liquid Propane (LPG) Conversion.
• Use a pressure reducing valve to reduce LP pressure supply as needed.
• Push or pull the pin located above Regulator as pictured below, for desired fuel type.
LPG NG
A. Liquid propane (LPG)
For engines set up to run on Liquid propane, please check the fuel supply pressure, lower or higher pressure range will result in equipment failure. Inlet pressure 1.7kPa to 3.5kPa, and gas line should be no longer than 16 feet or 5 meters, the inner diameter shall not be less than (0.63”) or 16mm.
It is strictly prohibited to remove high pressure gas lines during operation, service and repair. Contact your service provider. You must check and test for gas leaks using a gas leak detector before use. The observation time is not less than 1 minute per connection. Based on different gas sources that are available, there may be different gas pressures present. Make sure pressure is known before installation. A pressure reducing valve may be re­quired to obtain optimal requirements. You will need to use a pressure reducing valve if the pressure is exces­sively high. Additional parts and tools such as leak detectors and pressure gauges are not included with this purchase.

Regular maintenance is an important part of your investment and provides longevity of the complete genera­tor system. Keep it in good working condition according to the specications outlined and it will provide many years of dependable service.
The following generator maintenance specications are based on a good working environment. If working con­ditions are less than desirable (such as excessive dust, dirt and humidity, etc.) the maintenance interval periods should be shortened.
When maintaining the generator set, you should operate in strict accordance with the following requirements. Improper use and operation can cause premature failure.
Breaking-in period of New Engine
The life of the engine is greatly determined by the state of the rst cycle of use. It is recommended that the oil be replaced after only 30 hours of use on the rst cycle. The new engine should be operated as required. Abnormal engine wear will directly affect the life of generator engine.
Maintenance of the Fuel System
The genset is multi-fuel and comes preset from the factory to ether Natural Gas (NG) or Liquid Propane (LPG), Maintenance will vary according to the fuel used.
Fuel is ammable and an explosive material. Smoking is prohibited while
working or servicing generator.
When using Natural Gas (NG) or Liquid Propane (LPG)
• Before each operation, you should check all components for loose connections. Check for uid leaks around cylinders, pipes and hoses. Tighten as needed.
• Periodically check the gas pressure reducer and the solenoid valve sealing pad for deformities.
• Periodically check the low-pressure gas line to see if it has weathered or aged (soapy water can be used to detect leaks).
• When maintenance of the gas line is required, gas valve must be closed before any maintenance or repairs are carried out.

1. Routine Radiator Maintenance tips
• Regularly check radiator hoses. Inspect clamps and make sure they are secure.
• If hoses become deformed, develop bulges, hardening or cracking is visible, they need to be changed
immediately!
• Inspect and clean the cooling ns on the radiator regularly, use compressed air to blow out excess dust and dirt. Important! Blow compressed air from the inside out. Debris can build over time and affect the cooling system.
2. Routine Belt inspection tips
Adjust and replace timing belt and water pump belt as needed. Inspect them regularly for cracking or missing pieces of rubber. Timing belt needs replacement every 1,000 hours of use! Water pump belt is extremely important. It drives the water pump that cools the engine and entire system.
Note: Listen for sounds coming from the belts. If you hear the belts squealing when the generator starts up, this is a sign that the belts are loose or worn and the system will run hot! If belts show signs of cracks or pieces of belt are missing, contact service provider.
Important! To check to see if the belt is too tight make sure the main power
switch is in the off position.
Perform the following inspections and adjust or replace belt as needed.
Deection check of the belt: 7~10mm (0.28-0.35in) ∕ 100N {10.01kgf (22.1 lbs.)
Adjust the deected belt:
• Stop the engine.
• Use thumb to press on the belt between pulley wheels.
• If the tightness is not correct, adjust it by relaxing the tension wheel to the acceptable degree.
• Replace the water pump belt when it is cracked, missing pieces of rubber or singes of considerable wear.
