Turn OFF all electrical loads using the means provided such as a main circuit breaker or transfer switch 2 Let generator run at no load for a few minutes to stabilize internal engine generator temperatures 3 Place the Start Stop switch in its STOP position The engine will come to a complete stop 2 7 APPLYING LOADS TO GENERATOR When applying electrical loads to the generator observe these guidelines Before applying electrical loads let the generator stabilize and warm up for a minute or two DO NOT overload the generator 2 7 1 LETTING THE ENGINE STABILIZE The generator supplies correct rated voltage only at the proper governed speed Some electrical appli ances may be extremely sensitive to voltage Incorrect voltages can damage such appliances If electrical loads are applied at reduced operating speeds such loads imposed on the engine when suf ficient power is not available may shorten engine life Never turn ON electrical loads until after the genera tor engine has started and stabilized at no load 2 7 2 DO NOT OVERLOAD THE GENERATOR You can read the rated wattage amperage capacity of your generator on the generator data decal see Section 1 1 on Page 4 Applying electrical loads in excess of the unit s rated capacity will cause the engine generator to automati cally shut down To avoid overloading add up the wattage of all con nected electrical lighting appliance tool and motor loads
9. This total should not be greater than the gen erator s rated wattage capacity Most lighting appliance tool and motor loads indi cate their required watts on their nameplate or data plate For light bulbs simply note the wattage rating of the bulb If a load does not show its rated wattage multiply that load s rated VOLTS times AMPS to obtain WATTS Induction type motors such as those that run the vehicle s furnace fan refrigerator air conditioner etc need about 2 1 2 times more watts of power for starting than for running for a few seconds during motor starting Be sure to allow for this when connecting electrical loads to the generator First figure the watts needed to start electric motors in the system To that figure add the run ning wattages of other items that will be operated by the generator Do not apply heavy electrical loads for the first two or three hours of operation 2 8 PROTECTION SYSTEMS 2 8 1 LOW OIL PRESSURE SWITCH This switch Figure 2 3 on page 10 has normally closed N C contacts that are held open by engine oil pressure during cranking and operating Should oil pressure drop below a preset level switch contacts close and the engine automatically shuts down The unit should not be restarted until oil is added 2 8 2 HIGH TEMPERATURE SWITCH This switch Figure 2 3 which has normally open N O contacts is mounted near the oil filter The contacts close if the tempe
