A DC ammeter in series with the charger outputwill indicate a current reading approximately equal to theDC nameplate rating if the battery is discharged.LOW OIL LEVEL SHUTDOWN SYSTEMBriggs & Stratton powered generators - Some enginegenerator sets come equipped standard with the Briggs &Stratton OILGARD warning system.This low oil warning system will automatically stop theengine before the oil level reaches an operational dangerpoint. This feature is designed to prevent costly repairsand downtime.The OILGARD system uses a float in the engine crankcaseto sense the oil level. If a low oil level condition shouldoccur during operation, the float will ground out themagneto impulse, “killing” the engine. In addition, there isan indicator light mounted on the engine shroud near therecoil starter. This light will blink on and off to indicate alow oil level condition when you are attempting to start theunit. To get the engine started, you must add the requiredamount of oil to the engine crankcase.Use of the OILGARD system on applications that are subjectto shock, bumping or severe angles of operation (inexcess of 15 degrees) should be avoided. This isespecially true if an unexpected shutdown would cause asafety hazard or serious inconvenience for the operator.To disable the OILGARD, remove the wire attached to thesensor unit mounted on the engine crankcase. The wireshould be insulated with a connector or tape.Honda powered generators - These engine generator setscome equipped standard with the Honda Oil Alert System.The Oil Alert system is designed to prevent damage causedby an insufficient amount of oil in the crankcase. Beforethe oil level in the crankcase can fall below a safe limit, theOil Alert system will automatically shut down the engine(the engine switch will remain in the ON position).If the Oil Alert system shuts down the engine, the Oil Alertlamp will flash when you attempt to start the engine and itwill not run. If this occurs, check the engine oil level.AUTOMATIC IDLE CONTROL(DLC Series Only)The automatic idle control is a gas saving, solid statesystem, designed to reduce engine speed whenever theelectrical load is removed from the generator. Without aslow down control, the engine would run at full speed atall times, regardless of the electrical load. With theautomatic idle control switch in the 'Auto' position, thethrottle control lever is electrically released when the loadis turned on so it in no way interferes with the normalgovernor operation. When the load is turned off, the idlemagnet energizes and reduces the engine speed. It doesnot cause incorrect operation of the carburetor orgovernor, but neither does it correct them.The automatic idle control consists of a solid state module,switch, resistor and a transformer located in the generatorcontrol box, and an electromagnet mounted on the enginenear the throttle lever. The automatic idle control is onlyoffered as a factory installed feature. It is not available forfield installation.With the automatic idle switch in the “automatic” position,thesystem operates as follows:1. After the engine has been started, and no electrical loadis applied, the transformer senses and signals the solidstate module to turn ON the electromagnet. This will pulland hold the throttle lever, closing the throttle on thecarburetor and slowing the engine to an idle.2. When a load is applied to the generator, the transformersenses it and sends a signal to the solid state module toturn off the electromagnet. This allows the throttle torelease and allows the governor spring to open thethrottle. The engine will respond and come up to thegoverned speed (3600 rpm).3. When the electrical load is turned off, no power will flowthrough the transformer, and as a result, the automaticidle control will once again energize the magnet, pullingand holding the throttle at an idle.When the automatic idle switch is in the “manual” position,the engine will run at full governed speed regardless ofthe generator load.INITIAL START UPUse the following checklist to verify the correct preparation ofthe engine generator before starting.Before Starting always Check:1. Engine oil, fill as required with correct grade andquantity.2. Fuel level, fill as required with clean fresh fuel.3. Automatic Idle is in the 'Off' position4. Visually for loose parts.STARTINGThe throttle control on these generators is preset and lockedto operate at 3600 RPM (nominal) with no load speed setat 3750 RPM. Only a trained service technician should beallowed to adjust this speed setting. See “OperatingSpeed” section for additional information.NOTICE: ENGINE START LOCKOUTThis unit will not start if it is low on oil. The lubricating oillevel must be at the full mark before the engine will start.MANUAL STARTING - Refer to the engine manual foradditional starting, operating, and stopping instructions.1. Turn on the fuel supply.2. Move the choke to the full "on" position. A warm enginewill require less choking than a cold engine.3. Grasp starter grip and pull slowly until starter engages,then pull cord rapidly to overcome compression, preventkickback and start the engine. Repeat if necessary.4. When the engine starts, open the choke gradually.5. The engine should promptly come up to operatingspeed.Electric Starting - If the engine is cold and stiff or if thebattery is not fully charged, starting can be made easier byslowly hand cranking the engine through the compressionstroke before pushing the starter switch. This permits thestarter to gain momentum before the heavy load of the
