Page 11: Safety Information
Voltmaster Engine-Driven Generators Safety Information Operating safety DANGER Explosion hazard. ■ NEVER operate generator in an explosive atmosphere or near combustible materials. ■ Keep generator, engine, fuel, and other combustibles away from sparks, open flame, and burning objects. ■ Do not smoke near engine. - Page 12 Voltmaster Engine-Driven Generators DANGER Asphyxiation hazard. Engine exhaust contains carbon monoxide, a poison gas you cannot see or smell. ■ NEVER operate engine indoors, EVEN IF doors and windows are open. ■ Operate the engine OUTSIDE, far away from doors, windows, and vents.
- Page 13 Voltmaster Engine-Driven Generators WARNING Fire hazard. ■ Before transporting generator, drain fuel and close fuel shutoff valve. ■ A hot muffler can ignite flammable materials. Keep area around muffler free of debris such as leaves, paper, and cartons. ■ Remove all unnecessary grease and oil from generator surfaces.
- Page 14 Voltmaster Engine-Driven Generators ■ NEVER operate this equipment under the influence or drugs or alcohol. ■ When fueling electric-start engines, do not touch battery cables or posts to a gasoline supply can. ■ Before operating, know the location of the nearest fire extinguisher, first aid kit, and emergency telephone.

Page 15: Engine Safety
Voltmaster Engine-Driven Generators Engine safety 2.2.1 Operator safety Before using the generator, refer to engine manufacturer’s documentation for additional engine safety and operating information. 2.2.2 California Proposition 65 WARNING Health hazard. Engine exhaust and some of its constituents are known to the State of California to cause cancer, birth defects, and other reproductive harm. -
Page 16: Maintenance And Storage Safety
Voltmaster Engine-Driven Generators Maintenance and storage safety DANGER Explosion hazard. Do not use gasoline, other fuels, or flammable solvents to clean parts. DANGER Corrosive material. Battery acid will cause severe burns and blindness. ■ Use extreme care when handling or servicing batteries. - Page 17 Voltmaster Engine-Driven Generators ■ Before servicing, ensure power cannot be started inadvertently during service. ■ ALWAYS keep the generator in proper running condition. ■ ALWAYS fix damage to the generator immediately. Repair or replace broken or worn parts. Only use parts from original manufacturer.

Page 19: Operation
Voltmaster Engine-Driven Generators Operation Before starting 3.1.1 Safety Before operating the Voltmaster generator: ■ Read and be familiar with this instruction manual. ■ Read and follow all safety instructions (see Section 2, page 5). ■ Read and follow instructions in the engine manufacturer’s documentation. -
Page 20: Oil
Voltmaster Engine-Driven Generators 3.1.3 To avoid engine damage, always check oil level and refill oil if necessary before starting engine: ■ Crankcase pressure can blow hot engine oil out the fill tube, causing severe burns. Always stop the engine before removing the oil cap, and remove the cap with caution. -
Page 21: Battery For Electric-Start Models
Voltmaster Engine-Driven Generators 3.1.4 Battery for electric-start models For electric-start models the starter battery is user-supplied. Battery cables and a battery tray are installed on the generator at the factory. DANGER Explosion hazard. When connecting battery cables, first connect the positive (red) cable and then connect the negative (green) cable. -
Page 22: Ln-Series (Propane/Natural Gas) Models
Voltmaster Engine-Driven Generators 3.1.6 LN-Series (propane/natural gas) models LN-Series generators feature a special vapor fuel carburetor with a vacuum safety shutdown and an electric solenoid fuel shutdown. LN-Series generators are derated, because the liquid propane (LP) and natural gas (NG) fuel reduces engine output slightly versus gasoline. - Page 23 Voltmaster Engine-Driven Generators Fuel line The incoming fuel line should be a 1-inch line. Fuel connections on the generator are 3/4-inch NPT. To protect the flexible fuel line against rupture, route the fuel line away from the engine muffler and manifold. Do not remove the cover from the solenoid valve until you are ready to make pipe connections.

Page 24: Standby Installations
Voltmaster Engine-Driven Generators 3.1.7 Standby installations Safety concerns WARNING Shock hazard. Failure to isolate generator from power utility can result in death or serious injury. When using the generator for backup power: ■ Never connect the generator output to any live home or commercial electric circuits. - Page 25 Voltmaster Engine-Driven Generators Emergency circuit isolation To address the possibility of overloading the generator, the building may be wired so emergency circuits are grouped together, rewired to a separate junction box, and connected to the generator through a manual transfer switch.

Page 27: Operating The Generator
Voltmaster Engine-Driven Generators Operating the generator 3.2.1 Models LR50EL and LR60EL Model LR50EL and LR60EL generators feature electric-start engines with auxiliary recoil starters. To start the engine on these models if a battery is not available, move the red or black lever near the fuel pump to the up position. -
Page 28: Air In Fuel Line
Voltmaster Engine-Driven Generators 3.2.3 Air in fuel line For diesel models, air pockets in the fuel line will cause difficulty in starting and operating the generator. ■ Before starting, pump the fuel lever 20 times or more. ■ Do not allow the generator to run out of fuel or to the bottom of the fuel tank. - Page 29 Voltmaster Engine-Driven Generators D-Series diesel models CAUTION Operating a diesel generator without the proper load will permanently damage the engine. Always operate the diesel engine under load, using at least 25% of its rated capacity. Diesel models require a load of at least 25% of the generator’s rated output.
- Page 30 Voltmaster Engine-Driven Generators Plugs and connected equipment Use only 3-prong grounded plugs, 3-wire extension cords, and 3-wire or double-insulated power tools with the generator. Full-power switch Some models are equipped with a switch that allows selection of 120-volt power only or both 120- and 240-volt power.
