AMENDMENT TO SECTION 4 - ENGINE PREPARATION ‘Amend Section 4-3, PREPARING NEW BATTERY FOR SERVICE This unit may be equipped with a maintenance-free battery, a conventional wet charged battery, or a dry charged bat- tery. Maintenance-free batteries do not have conventional vent caps since they do not require the addition of water during normal service. Once the battery type is determined, read the following WARNING and proceed to the ap- propriate section: A. Maintenance-Free Battary; B. Wet Charged Battery; C. Dry Charged Battery. BATTERY ACID can burn eyes and skin and destroy clothing and other mat ‘© Wear correct eye and body protection when working with batteries. ABNORMAL VOLTAGE can cause damage to engine electrical component: ‘Do not operate engine without the battery connected. © Do not disconnect the battery while the engine is running. A. Maintenance-Free Battery To place this battery in service connect the negative (-) battery cable to the negative battery terminal. No other preparation should be required. B. Wet Charged Battery Connect the negative (-) battery cable to tha negative terminal on the battery. if the battery has enough power to start the engine, it will charge up while the engine is running. However, if the battery fails to supply enough power to crank the engine, the battery will require recharging. : CHARGING A FROZEN BATTERY can cause the battery to explode and result in serious por sonal injury or damage to equipment. ‘© Chock the state of the electrolyte solution and allow battery to warm to 60°F (16°C) before charging it elec- trolyte is frozen or slushy. Remove the vent caps and refer to Section 4-3C, Steps 7-9 for charging instructions, C. Dry Charged Battery 1. Obtain battery grade (1.265 specific gravity) electrolyte solution, 2, Remove battery from unit and place on a level worktable or other suitable surface, 3. Remove vent caps. BATTERY 1g and other mat BATTERY ACID can burn eyes and skin and destroy clot GASES can explode and shatter the battery. © Wear correct eye and body protection. Do not spill or splash battery fuid. © Donat apply pressure to wall of filled battery-use battery corrier or place hands on opposite corners when lit ting battery, Do not lean over battery when testing. Keen sparks, flames, cigarettes, and other ignition sources away from batteries. Use enough ventilation to keep battery gases from building up during activation. 4. Fill battery cells to top of separators with electrolyte, 5. Allow battery to stand for 20 minutes. 6. Recheck electrolyte level and add if necessary to fill to top of separators. 3/28/82 oma104 Page7. Check electrolyte temperatura in one of the center cells with a battery thermometer. For each 10°F (6°C) incre- ment above 80°F (27°C), a correction factor of 0.004 specific gravity must be added to the specific gravity reading taken in Step 8, For each 10°F (6°C) increment below 80°F (27°C), 0.004 must be subtracted from the reading taken in Step 8. 8. Check the specific gravity of each cell with a hydrometer. (Draw in and expel the electrolyte two or three times from the first cell to be tested to adjust the temperature of the hydrometer to that of the electrolyte). Follow the precautionary steps below in addition to those given in the previous WARNING statements, © Use enough ventilation to keep battery gases from building up during and for several hours after battery charg- ing. Turn battery charger off before making connection to battery. Do not touch or move connections on battery while battery charger is on. Do not lean over battery when charging. Be sure battery charger connections to battery are clean and tight. ‘Keep vent caps in place and cover top of battery with damp cloth. Be sure battery charger output matches battery voltage. Ifa corrected specific gravity reading of 1.260 at 80°F (27°C) is not obtained, replace the vent caps and recharge ‘the battery following the battery charger manufacturer's instructions. BATTERY GASES can explode and shatter the battery. ‘© Turn the battery charger off before disconnecting the charger from the battery. 10, Recheck electrolyte level and add if necessary. BATTERY ACID is corrosive to metals. 11. Thoroughly rinse with water and mutilate empty electrolyte containers before discarding. 12. Reinstalt battery in welding generator. . 13. Replace battery holddown and tighten securely. Oo not overtighten. 14. Connect positive (+) battery cable to positive (+) battery terminal. 18.

Under this heading, explanatory statements will be found that need special emphasis to obtain the ‘most efficient operation of the equipment. Figure 3-1. Dimensions And Base Mounting Hole Layout OM-410 PagesFigure 3-2. Allowable Tilt Angles 3. 1, LOCATION (Figure 3-1) - A proper installation site should be selected for the welding generator if the unit is to provide dependable service, and remain relatively maintenance free. This unit must be located on an ap- proximately level surface to ensure proper engine lubrication and gasoline engine carburetor operation. Figure 3-2 shows the maximum alfowable tilt for safe operation. Exceeding these limits can cause severe engine damage. Oil level in the crankcase must be checked when the unit is on a level surface. If this unit is to be operated indoors, it should be located in a place where the exhaust furres from the engine can be vented out of the building. Foilure to comply with proper venting may result in serious bodily injury or loss of lite. Wf this welding generator is to be ‘mounted on a trailer (optional), ensure that the engine end is mounted toward the front (hitch end) of the trailer to maintain proper weight distribution. Also en- sure that the tongue weight of the trailer is approx- imately 10% of the gross vehicle weight. It is recom- mended that a properly fitting canvas cover (optional) be placed over the welding generator when not in operation to protect the unit from the environment. The engine exhaust system on this welding generator has not been equipped with a spark arrestor unless it was specifically ordered as an optional accessory. A spark arrestor, maintained in effective working order, 's mandatory if this welding generator is to be operated in a National Forest, or on California Grasslands, brush, or forest covered land (see Section 4442 of California Public Resources Code). For other areas, check your state and local laws. ‘A proper installation site permits freedom of air move- ment into and out of the welding generator, and also least subjects the unit to dust, dirt, moisture, and cor- rosive vapors. A minimum of 18 inches of unrestricted space must be maintained between the welding ‘generator front and rear panels and the nearest obstruc- tion. Also, the underside of the welding generator must bbe kept completely free of obstructions. The installation site should also permit easy removal of the outer enclosure for maintenance functions. Poae6 Do not place any filtering device over the intake air passages of the welding generator as this would restrict the volume of intake air and thereby sub- ject the internal components to an overheating cond tion and subsequent failure, Warranty is void if any type of filtering device is used. Holes aro provided in the base for mounting purposes. Figure 3-1 gives overall dimensions and the base ‘mounting hole layout. On all welding generators a lifting device is provided for moving the unit. However, if a fork lift vehicte is used for lifting the unit, be sure that the lift forks are long ‘enough to extend completely under base. The use of lift forks too short to ex- tend out of the opposite side of the base will expose i- ternal components to damage should the tips of the lift forks penetrate the bottom of the unit 3-2, EQUIPMENT GROUNDING (Figure 3-3) ~ Normally engine-driven welding generators do hot require grounding. However, this machine has aux- iliary power plant capability; therefore, grounding of the frame and case is recommended, Also, unusual cir- cumstances may require machine grounding. For these reasons a convenient grounding terminal is provided on all weld /powor units. For detailed grounding instructions consult your local or stato codes or the latest issue of the National Electrical Code. if additional information regarding your particular operating circumstances and/or grounding re quirements is needed, consult a qualified electrician or your dealer. After determining the extent to which any grounding requirements apply to your particular situa- tion, follow them explicitly Equipment Grounding "Terminal Figure 3-3. Equipment Grounding Termipal 3-3. WELD OUTPUT CONNECTIONS (Figure 5-1) ~ To obtain the full rated output from this unit, itis necessary to select, install, and maintain proper welding ‘cables. Failure to comply in any of these areas may result in less than satisfactory welding performance. The weld output receptacles are elec- trically energized when the engine i running. Ensure that the unit is completely shut down before making weld output connections. Disconnect the welding cables when not welding and do not touch the output receptacles when the engine is running.A. Location ‘The ELECTRODE and WORK AC WELD output recep- tacles are located on the center portion of the front panel. B. Welding Cables If welding cables were not ordered with this unit, the stops listed should be followed to ensure the best welding performance: 1. It is recommended that the welding cables be kept as short as possible, be placed close together, and be of adequate current carrying capacity, The resistance of the welding cables ‘and connections causes a voltage drop which is ‘added to the voltage of the are, Excessive cable rosistance may resutt in overloading os well a3 reducing the maximum current output capability Of this unit. Proper operation is to a great extent dependent on the use of welding cablos and con- nections that are in good condition and of ade- quate size. An insulated electrode holder must bbe used to ensure the operator's safety. 2. Use Table 3-1 as 2 quide for selecting correct cable size for the anticipated maximum weld cur- rent which will be used. Table 3-1 shows total cable length, which includes the electrode and work cable,’ Example: If the electrode holder cable is 75 feat long and the work cable is 25 feet long, select the size cable that is recommended for 100 feet at the maximum weld current that is to be used. 3. Do not use damaged or frayed cables. 4, Follow the electrode holder manufacturer's in- structions for installing the electrode holder onto the wold cable. 5. Use correct lugs on the weld cable to connect the work clamp. 6. Ensure that all connections are clean and tight. Tabio 3-1.

LUBRICATION (Figure 4-1) - This engine was shipped from the factory with the crankcase filled with the correct amount and type of break-in oil unless other- wise ordered. Check the oil level before attempting to operate the engine, It should be up to the full mark on the dipstick. Add a quality brand of detergent oil if the «il level is low. See the oil selection chart (Table 9-1) in Section 9. New engines have very close clearance between the moving parts. Thus, itis recom mended that loading of the engine be kept to @ ‘minimum during the first 10 hours of operation. Be sure to check the oil level several times each day during the engine break-in period. This engine requires ebout 50 hours of running time before becoming fully broken in, andl Figure 4-1. Oil Level indicator (Manual Start Models Illustrated) ‘After about 100 hours of running time, drain the break- in ol. See tho oil selection chart (Table 9-1) in Section 9 for correct oil type and grade to use after the break-in oil is drained. 4-2. FUEL (Figure 42) Never attempt to fil the fuel tank with the engine running. Do not fil the fuel tank completely as cold fuel will expand when exposed to outside temperature in a warm climate or to engine heat. If the tank is too ful, it will overflow causing @ potential fre hazard. Never allow fuel to drain on the engine or other ‘components. Do not mix oil with the gasoline. Use @ good grade of “regular”, “low lead”, or “no lead” ‘gasoline of at least 85 octane for this engine. The “low lead” or “no lead’ fuels lower the pollution factor and reduce combustion chamber deposits if used exclusive- y. Fuels of lower octane rating may cause detonation (knocking) which could result in damage to the engine. if unable to obtain fuel of suitable octane rating, consult the Engine Manufacturer's Service Facilty for suitable ‘ongine modifications. Pages ‘The fuel capacity of the fuel tank is 3.6 gallons (U.S. Measure). To reduce potential fire hazards, inspect for fuel and/or leeks prior to putting the unit into ser- vice. Continue to check for leeks during the break-in period and periodically thereafter. Oil seepage may exist at the main bearing seals beyond the normel breek-in period. had Pas Figure 4-2, Fuel Consumption Chart Figure 4-2 illustrates typical fuel consumption under specific toad conditions. Fuel consumption will vary from one engine to another. Different brands of fuel, ‘operating conditions, condition of the engine, etc., will affect the fuel consumption of this engine. 4-3.

If the battery has enough power to start the engine,-t will charge up while the engine is running. Tho wot charged battery is shipped with the electrolyte solution added and normally in an operational status. However, due to long periods of idleness, the battery ‘may become weak and thus require charging. The bat- tery should have @ specific gravity reading of 1.260 (at 80°F) when fully charged. If the battery requires charg- ing, see Section 4-3B, Step 4. B. Dry Charged Battery This battery is shipped in a dry state, To prepare thenew battery for operation, it will be necessary to obtain electrolyte and proceed as follows: TMI Pur on protective eye cover and clothing prior to pouring the electrolyte solution. 1. Remove the battery from the unit and place it on a level worktable or other suitable area. 2. Fill the battery cells to the required level with electrolyte. 3. Place a battory thermometer in one of the center cells and check the specific gravity of each cell with a battery hydrometer. 4, “Thebattery should have a specific gravity of 1.260 (at 80°F) prior to installation. If this condi tion is not met, charge the battery as follows: Ensure that the battery caps are removed before charging. Failure to do so may cause the battery to explode should overcharging occur. ‘a. Use an automotive type battery charger This battery should be charged at about a 3.5 ampere rate until correct electrolyte con- ditione are met. Lower charging rates can be used; however, the time to obtain the cor- rect electrolyte conditions will be longer. b. When tho battery is charged, disconnect it from the charger and recheck the electrolyte level. Add if necessary. Install the battery caps. 5. Rinse the empty electrolyte containers with water before discarding. Since battery acid is corrosive to metals, do not pour into a metal sink ‘or drain, Rinse and muttilate the empty oloc- trolyte container before discarding. If acid has accidentally spilled on the battery or work area during filing or charging, flush off with clear water and neutralize with soda or ammonia solu- tion. Use the same procedure if acid is spilled on clothing. 6. Reinstall the battery in the unit ensuring that the negative (-) battery cable is connected to the negative (-) battery termina. 4-4.

This vill prevent engine compression from turning the rotor and catching the repairman’s hand between the rotor fan casting and the stationary adapter casting. Also, disconnect the negative (-) battery cable from the ‘battery (if applicable). 8 - 1, GENERAL - Economical operation and trouble- free service of this welding generator are based upon regular inspections and reasonable attention. Occasional blowing out of the unit with clean, dry, com: pressed air is recommended. This should be performed periodically, depending upon the location of the unit and the amount of dust and dirt in the atmosphere. 8 - 2. COLLECTOR RING BRUSHES - The brushes should be inspected periodically to ensure their proper function. The brush life is very good under normal con: ditions, If the generator has been operating in an ex- tremely dust or dirty location, a close check of the brushes for freedom of movement and cleanliness should be made weekly. Under normal use slip rings will discolor to a dark brown. If it should become necessary to clean the slip tings use a 3/0 or finer sandpaper followed by @ crocus cloth, Never use emery cloth as part of the emery will embed itself into the collector rings and in turn destroy the carbon brushes. 8-3. WELDING CABLES - Check connections periodically for tightness. The cables should be in- spacted frequently and all breeks in the insulgtion should be repaired or the cables replaced. mes SECTION 9 - ENGINE MAINTENANCE ===—____0291—~ 9-1. PERIODIC SERVICE - The efficiency of the engine depends a great deal on the care and attention given it. By following a definite schedule of inspection ‘and service, engine failure caused by naglect can be avoided. Service periods are based on hours of running ‘time and are for normal operating conditions. For ex- treme conditions of load, dust, ditt, etc., service more often. 9-2. LUBRICATION - This engine requires at least 50 hours of break-in running time. During this break: pporiod the load on the engine should be kept as light as possible and the oil level maintained at the FULL mark. After the break-in period, drain the break-in oil and fill the crankcase to the FULL mark with a good quality (API) SE oil (gasoline operation only). Table 9-1 gives a list of recommended grades of oil to use to keep oil evel Up during break-in and to use after the break-in oil is drained. If SE oil is not available, SD or SD/CC ofl may be used.

Remove tho plugs periodically and clean the electrode with a wire brush or knife blade. Take care s0 as not to ‘rack the porcelain insulator on the snark plugs. 9-5. FUEL FILTER ~ The fuel filter is located bolow the fuel tank. Check the sediment bow! periodically for water and dirt deposits. How often the filter has to be checked will depend on the quality of gasoline used and. how dusty and dirty the location in which the engine is being used. 9-6. AIR CLEANER - Tho air cleaner is one of the ‘most important parts of the engine from the standp. of engine lfe. If dirty alr gets into the engine, itcan wear ‘out a set of piston rings within a few operating hours. “This engine is equipped with a dry paper type filter ele- ment. Dry paper element type cleaners can be cleaned by removing the element and tapping lightly, causing loose dirt to fall off. The element should be rplaced if dirt does not drop off easily. ‘The paper element should be handled with care to avoid perforations, Removing the dirt with compressed air ‘can rupture the paper olement. Check to ensure that ‘gasket surfaces of the element are not bant or damaged in any way. Gasket surfaces must seat tightly at the top and bottom of the cleaner shell to prevent foreign mat- ter from entering the carburetor, Whenever the air cleaner is removed, cover the air in- take hole to prevent dirt from falling into the carburetor. 9-7, GOVERNOR - The governor has been set at the factory and should not require further adjustment.

SPARK ARRESTOR (Optional) The engine exhaust system of this welding generator has not been equipped with a spark arrestor unless it was specifically ordered as an optional accessory. A spark arrestor, maintained in effective working order, is mandatory if this welding generator is to be operated in a National Forest, or on California grasslands, brush, or forest covered land {see Section 4442 of California Public Resources Code). For other areas, check your state and local laws. Internal combustion engines operating in a highly com- bustible environment ere a common fire hazard. Glow. ing carbon particles blown out with the exhaust can re- ‘ain sufficient heat to ignite materials. While no prac- ticat spark arresting device will stop all sparks, this device wil minimize fire hazards by removing and trap- ping most solid particles provided that it is properly maintained, ‘The carbon trap should be serviced weekly or every 50 operating hours, whichever occurs first. The entire spark arrestor should be inspected every 1000 operating hours or three times per season. A. Inspection 1. Visually examine the outside of the device for holes, cracks, or metal corrosion, 2. With the engine stopped, look inside the spark arrestor outlet tube with a flashlight or other ight. source.
