Tighten or loosen belt until: d = 0.016 X L

If the control box is not located on the correct side for your application, it can be rotated to the opposite side. First remove the fan vents, than remove the four drive end bracket bolts. Rotate the

drive end bracket 180°, re-torque bolts to 17 ft•lb. Reinstall the fan vents. Remove the four screws at the base of control box, rotate the control box 180°. The voltmeter is now on the back of the machine instead of the front. See below for terminology.

DANGER Remember, exhaust fumes are deadly carbon monoxide gas, and must be vented to the outside where there are no people. Cooling air of sufficient amounts must be brought in and exhausted out to ensure proper cooling of the engine and generator.

If you desire to direct couple the generator00298to an engine, great care must be taken to align the shaft of the generator and engine to within the specified tolerances of the chosen coupler.

NEVER install your generator inside confined areas. Inside installation can cause health hazards or death.

LOAD APPLICATION

contaminants. Over time the effectiveness of the insulation is eliminated and a dead short can result.

Always compare the generator nameplate data with that of the equipment to be used to ensure that watts, volts, amperage, and frequency requirements are suitable for operating equipment. The wattage listed on the equipment nameplate is its rated output. However, some equipment may require three to ten times more wattage than its rating on the nameplate, as the wattage is influenced by the equipment efficiency, power factor and starting system. NOTE: If wattage is not given on equipment nameplate, approximate wattage may be determined by multiplying nameplate voltage by nameplate amperage.

VOLTS	X AMPS	= WATTS
Example: 120V	X 5A	= 600W
When connecting	a resistive load such as

incandescent lights, heaters or common electric power tools, a capacity of up to the generator full rated wattage output can be used.

When connecting a resistive-inductive load such as a fluorescent or mercury light, transformers or inductive coils, a capacity of up to 0.6 times the generator’s full rated output can be used.

Always allow the generator to reach operating speed before a load is applied.

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 more current to start than to run. Capacitor motors are easier to start and usually require 2 to 4 times as much current to start than to run. Repulsion Induction motors are the easiest to start and require

1.5to 2.5 times as much to start than to run.

Most fractional motors take about the same

amount of current to run them whether they are of Repulsion-Induction (RI), Capacitor (Cap), or Split- Phase (SP) type. The following chart shows the approximate current required to start and run various types and sizes of 120 volt 60 cycle electric motors under various conditions.

It is important to determine the total electrical load before it is connected to the generator. The two major factors in determining the life of a generator head are: heat build up, caused by overloading the generator and corrosive contaminants, that attack the wiring insulation. If the generator is overloaded, the wires become excessively hot and cause the insulation to break down, reducing its ability to resist corrosive
