STARTING ELECTRIC MOTORS
Electric motors require much more current (Amps) to start than to run.
Some motors, particularly low-cost split-phase motors, are very hard to start and require 5 to 7 times as much current to start them than to run them. Capacitor motors are easier to start and usually require 2 to 4 times as much current to start them than to run them. Repulsion
Induction motors are the easiest to start and require 1 1/2 to 2 1/2 times as much current to start them than to run them.
Most fractional horsepower motors take about the same amount of current to run them whether they are Repulsion Induction (RI),
Capacitor (C), or Split-Phase (SP) type. The chart below shows the approximate current required to start and run various types and sizes of
120 Volt, 60 cycle electric motors under average conditions.
2. Before proceeding with the preparations of your new generator for operation, take a couple of minutes to ensure the unit you have received is the correct model and review the specification pages in this manual to ensure that this unit meets your job requirements.
UNIT INSTALLATION
Plans for installation should be prepared with proper attention to mechanical and electrical engineering detail to assure a satisfactory system installation. The information in this manual is offered as a guide to finalizing your installation plans. The installation sequence is summarized below.

The figures given above are for average load such as a blower or fan.
If the electric motor is connected to a hard starting load such as an air compressor, it will require more starting current. If it is connected to a light load, or no load such as a power saw, it will require less starting current. The exact requirement will also vary with the brand or design of the motor.
Generally, two-bearing generators are used on portable equipment. For best service consider the following:
1. All electrical equipment should be protected from excessive moisture. Failure to do so will result in deterioration of the insulation and short circuits and grounds.
2. The generator should be installed in a sheltered area. If the unit must be left in the open, it should always be protected with a weather cover such as a tarp or large piece of canvas after each use to keep out water and dust.
CAUTION: EQUIPMENT DAMAGE
Always allow the generator and prime mover to cool before covering with a flammable weather covering.
MOUNTING
Self- exciting generators respond to severe overloading differently that utility power. When over loaded, the engine is not able to supply enough power to bring electric motor up to operating speed. The generator responds with high initial starting current, but the engine speed drops sharply. The overload may stall the engine. If allowed to operate at very low speeds, the electric motor starting winding will burn out in a short time. The generator winding may also be damaged.
60706-255 4
CAUTION: EQUIPMENT DAMAGE
The generator must be mounted with the engine to a common rigid base to prevent stress on the engine and generator shafts and bearings due to vibration displacement. For permanent installations, the engine-generator is usually mounted on a sub-frame which can be shock mounted with neoprene pads on the main frame.
REV A
Before proceeding with installation, be sure that you have completely read and understood the assembly and installation instructions.
An engine with adequate horsepower and a close regulated (fixed speed) governor is required for satisfactory operation of this generator.
About 1.4 horsepower is required to produce 1,000 Watts of generator output power assuming 100% efficiency of both the engine and the generator. However, due to engine and generator efficiencies of 80 to 90%, the loss of power due to engine driving accessories such as cooling fans, battery charging alternators, etc. friction losses and slippage in the drive pulleys and belts, the general conservative rule of thumb allowing approximately two (2) horsepower for every 1,000
Watts of generator output is much more realistic. For example, the
6,000 Watt generator output will require a 12 horsepower engine for full output, good speed/voltage regulation, and satisfactory load performance. When determining the prime mover/generator pulley ratio to drive the generator at the correct operating speed, bear in mind the power rating of most prime movers (usually an engine) varies with speed. It produces more power at higher speeds, less when slowed.
The prime mover must be fast enough to reach desired horsepower for good generator operation.
The normal slight variations on speed also directly affect the frequency of the output current. This frequency variation has no appreciable effect in the operation of most loads (such as motors, lights, and most small appliances).
The speed of the engine is usually adjusted so that the generator produces proper voltage. If the adjustment is made “cold”, set the voltage a little higher than normal since it will drop a few Volts as the generator warms up.
NOTE: When operating continuously at full load, the generator shell becomes very warm. It will be uncomfortable to the touch. This is normal for any high performance inherently regulated generator. Output voltage should be checked periodically to ensure proper operation of the generator and appliances.
The drive belt system must be of adequate size and must be tight enough to power the generator without slippage. Be careful not to over-tighten to the extent that it puts excessive strain on the bearings.
Doing so can cause bearing failure and other possible damage to the generator.
Alignment of the generator to the prime mover is important.
Misalignment of the pulleys will cause excessive belt and pulley wear and unnecessary stress on the prime mover.
CAUTION: EQUIPMENT DAMAGE
Low voltage may damage any motors or appliances connected to it.
Running the generator at excessively high speeds result in high voltage which will also damage electrical devices connected to it. Excessively high speed may also cause damage to the generator armature windings.
CONNECTING THE LOADS
APPLYING THE LOAD
A short warm-up time will permit the engine to work more efficiently when the load is applied and will reduce the wear and extend its life.
Receptacles have been provided on the end cover to connect the loads on this generator.
The following table shows the effect of various operating speeds and electrical loads on a typical generator when matched and mounted to an adequate prime mover.

*Note: Required generator speed must be at 3600 +/- 90 RPM under all load conditions.
Although individual units and models may vary slightly, the normal voltage and frequency of typical 60 cycle engine-driven generators described in this manual are approximately as follows when powered by a typical prime mover (engine) run first with no load applied, then at half capacity as rated on the nameplate.
CAUTION: EQUIPMENT DAMAGE:
Keep the generator load within the generator and receptacle nameplate ratings. Overloading may cause damage to the generator and/or loads.
Most electric tools and appliances will have the voltage and amperage requirements on their individual nameplates. When in doubt, consult the manufacturer or a local electrician. The nameplate’s amperage rating for electric motors can be misleading. See “Starting Electric
Motors” in specification section.
The generator is a limited source of electrical power, therefore pay special attention to the receptacle and generator ratings. The nameplate rating can be obtained through combination of receptacles or a single receptacle as long as the receptacle amperage rating is not exceeded. Both the 120 and 240 Volt output can be utilized at the same time. See specification section for proper load separation. Overloading a specific receptacle or winding group can result in damage to the equipment.
All engines have a tendency to slow down when a load is applied.
The governor on the engine is designed to hold engine speed nearly constant. When the electrical load connected to the generator is increased, the engine is more heavily loaded and as a result, the speed drops slightly. This slight decrease in speed together with the natural “voltage drop” within the generator itself due to load current and heating of the windings, results in a slightly lower voltage than when the generator is running idle.
REV A
Plug your tools such as drills, saws, blowers, sump pump, and other items to be powered directly into the generator receptacles. Before plugging in all of the tools and cord sets, recheck the rating of the generator. Be sure it can handle the intended load and is compatible with voltage, phase, and current ratings.

‘Hard Wiring’ this unit directly into a temporary construction site electrical system is NOT A SIMPLE DO-IT-YOURSELF JOB. For
60706-255
your safety, all wiring must be done by a qualified electrician and conform to the National Electric Code and all state and local codes and regulations. Check with local authorities before proceeding.
WARNING: PERSONAL DANGER
A fully isolated, double pole throw manual transfer switch must be installed any time a generator is being connected to an existing distribution system.
SYMPTOM
Low voltage
Output voltage too high
Generator overheating
No output voltage
CAUTION: EQUIPMENT DAMAGE
Failure to properly limit and balance the load applied to the generator will cause the generator to produce low voltage and may damage the generator. It may also cause severe damage to the loads connected to the generator at that time. Improper loading of the generator constitutes abuse and will not be covered by warranty.
