Page 5 1. INTRODUCTION This manual provides general safety information for installing, operating and maintenance of Armstrong Power equipments. The purchaser should comply with the instructions and information in this manual, and is strongly advised that all personnel to be associated with the equipment supplied should be made familiar with the information contained herein.
Page 6 3. FIRE AND EXPLOSION Risk of serious injuries or death Fuels and fumes associated with generating sets can be flammable and potentially explosive. Proper care in handling these materials can dramatically limit the risk of fire or explosion. However, safety dictates that fully charged BC and ABC fire extinguishers are kept on hand. Personnel must know how to operate them. • • • • • • • • • The acids in the battery can cause explosion.
Page 7 5. MECHANICAL The generating set is designed with guards for protection from moving parts. Care must still be taken to protect personnel and equipment from other mechanical hazards when working around the generating set. • • Do not attempt to operate the generating set with safety guards removed. While the generating set is running do not attempt to reach under or around the guards to do maintenance or for any other reason.
Page 8 7. NOISE Generating sets that are not equipped with sound attenuating enclosures can produce noise levels in excess of 105 dBA. Prolonged exposure to noise levels above 85 dBA is hazardous to hearing. • Ear protection must be worn when operating or working around an operating set. 8. ELECTRICAL Safe and efficient operation of electrical equipment can be achieved only if the equipment is correctly installed, operated and maintained.
Page 9 9. FIRST AID FOR ELECTRIC SHOCK Identification / look out for: • Unconsciousness and Burns • Establish site of entry and exit of electric shock What to do: • Switch off the main switch. • Break the contact between electrical source and patient using dry non-conductive object like wooden stick. • Call for help. • If breathing and heartbeat has stopped begin CPR 1. CALL Check the victim for unresponsiveness. If there is no response, Call 911 and return to the victim.

Page 12 1. LOCATION The generating set sub base tank or frame (if it’s the case) is specifically designed for ease of moving the set. Improper • handling can cause serious damage to the generator and components. Never lift the generating set by attaching lugs to the engine or alternator. Shackles and chains of suitable length and lifting capacity must be used. A spreader bar is required to prevent damaging the set.

For that reason, There are a number of different generator systems and the following precautions are necessary: typical loads in the context of electrical systems. Most systems, unless they contain automated switch gear, have a • Avoid contact with hot engines, exhaust manifolds, exhaust piping and mufflers. Any of these can cause means of disconnect between the generator and the severe burns. load.
Page 15 6. INSTALLATION CHECKLIST BATTERY INSTALLATION Battery is connected properly. Recommended battery is installed. Cables are clean and tight. Terminals are coated with anti-corrosion grease, and terminal covers are positioned. FUEL SYSTEM Complies with local and NFPA codes. Fuel is connected and checked for leaks. Correct fuel pressure (11-14 inches of water (0.6 psi) at all load ranges). Load block adjusted for maximum power for natural gas fuel.

Page 18 6. PRE-OPERATION CHECK Before starting, complete the following: 1. Set the generator's Start/stop switch to the Stop position. 2. Turn OFF the utility power supply to the transfer switch using the means provided (such as the utility main line circuit breaker). 3. Check the engine crankcase oil level and, if necessary, fill to the dipstick FULL mark with the recommended oil. Do not fill above the FULL mark. 4. Check the fuel supply. All fuel shutoff valves in the fuel supply lines must be open.

Apply an electrical load equal to the full rated wattage/amperage capacity of the installed generator. • After about six seconds, the switch should transfer loads back to the utility power source. About one minute after retransfer, the engine should shut down. Check the installation and application data charts for any 9.

Page 31 WARNING Do not mix gasoline, alcohol, or gasohol with diesel fuel. This mixture can cause an explosion. CAUTION Due to the precise tolerances of diesel injection systems, it is extremely important that the fuel be kept clean and free of dirt or water. Dirt or water in the system can cause severe damage to both the fuel pump and the fuel injectors. Cummins Inc. recommends the use of ASTM number 2D fuel. The use of number 2 diesel fuel will result in optimum engine performance.
Page 32 The use of quality engine lubricating oils, combined with appropriate oil drain and filter change intervals, is a critical factor in maintaining engine performance and durability. Cummins Inc. recommends the use of high-quality SAE 15W-40 heavy-duty engine oil, such as Valvoline® Premium Blue®, which meets performance specifications as listed below.
Page 33 Water Quality Calcium Magnesium (hardness) Maximum 170 ppm as (CaCO3 + MgCO3) Chloride 40 ppm as (CI) Sulfur 100 ppm as (SO4) Cummins Inc. recommends using Fleetguard® Compleat. It is available in both glycol forms (ethylene and propylene). Fully formulated antifreeze must be mixed with good-quality water at a 50/50 ratio (40- to 60-percent working range).
Page 34 In case of complete overhaul of genset, the bearing of the generator should be changed. On request prelubricated bearings with regreasing system can be mounted. When regreasing use 20/ 30 grams of grease. Following types of grease are to be recommended for normal application: MOBIL OIL: MOBILUX 3 SHELL: ALVANIA 3 AGIP: GR MW 3 ESSO: BEACON 3 9.3.
