FUEL

At the end of each day’s use, refill the fuel tank to minimize moisture condensation and dirt contami- nation in the fuel line. Do not overfill; leave room for the fuel to expand.

Use only fresh, No. 2 grade DIESEL fuel. Do not use kerosene.

See the Kubota Engine Operator's Manual for instruc- tions on replacing the fuel filter. See Table D.2 for rec- ommended fuel filters.

BLEEDING THE FUEL SYSTEM

You will need to bleed air from the fuel system any time the fuel filter or fuel lines have been detached and refitted; after the fuel tank has been run out of fuel; or before using the engine after long storage. Bleed the fuel system as follows:

WARNING

To avoid personal injury, do not bleed a hot engine. This could cause fuel to spill onto a hot exhaust man- ifold, creating a danger of fire.

AIR CLEANER

The Kubota diesel engine is equipped with a dry type air filter. Never apply oil to it. See Table D.2 for recom- mended air cleaner. Service the air cleaner as follows:

1.Remove the dust cup from the bottom of the air cleaner housing. Clean out any accumulated dust.

2.If dust is sticking to the element, blow compressed air through the element from the inside out. Turn the element as you apply air. Air pressure should be under 99 psi (68 newton/cm2). Replace the fil- ter if there is carbon or oil on the element.

3.Replace the element at least every 600 hours of operation and sooner under dusty conditions.

TIGHTENING THE FAN BELT

If the fan belt is loose, the engine can overheat and the battery lose its charge. Check tightness by pressing on the belt midway between the pulleys. It should deflect about .25 in. (6 mm) under a load of 20 lbs. (9 Kg).

Refer to Figure D.2

1.Fill the fuel tank. Open the fuel cock.

2.Open the air vent plug on the fuel injection pump two turns using a 10mm wrench.

3.Move the fuel feed pump lever by hand until fuel flows out of the air vent plug.

4.Tighten the air vent plug.

WARNING

HOT COOLANT can burn skin.

• Do not remove cap if radiator is hot.

Check the coolant level by observing the level in the plastic reserve overflow tank. Add 50/50 antifreeze/ water solution if the level is close to or below the “LOW” mark. Do not fill above the “FULL” mark. Remove radiator cap and add coolant to radiator if overflow tank is empty.

To drain the coolant, open the petcock at the bottom of the radiator. Open the radiator cap to allow com- plete drainage. (Tighten the petcock and refill with a 50/50 antifreeze/water solution.) Use an automotive grade (low silicate) ethylene glycol antifreeze. The cooling system capacity is 5.4 quarts (5.1l.). Replace and tighten the radiator cap.

SVM148-B specifications

The Lincoln Electric SVM148-B is a state-of-the-art inverter-based power source designed for both professional welders and hobbyists. As a versatile machine, it excels in a variety of welding applications including MIG, TIG, and stick welding. This machine is particularly notable for its efficiency and portability, making it an ideal choice for on-site projects or workshops where space is limited.

One of the main features of the SVM148-B is its inverter technology. Unlike traditional transformer-based welders, inverter welders are typically lighter and more compact. This means that users can transport the machine more easily without sacrificing power or performance. The SVM148-B is capable of delivering a substantial amperage range, allowing for adjustments that suit various materials and thicknesses, from thin sheet metal to thicker plates.

The machine offers adjustable output levels, providing precise control over the welding process. This level of control is essential for achieving clean, strong welds and is especially useful when working with different materials. The SVM148-B is equipped with digital display features that provide real-time feedback on power settings and welding parameters, allowing welders to make quick adjustments as needed.

Another significant advantage of the SVM148-B is its duty cycle, which is designed to accommodate extended usage without overheating. A robust duty cycle means that professionals can rely on this machine for prolonged periods, making it a dependable choice for heavy-duty tasks.

The SVM148-B also includes advanced safety features such as overload protection, which ensures that the machine will shut down in the event of excessive current draw. This feature not only protects the equipment but also enhances user safety during operation.

Moreover, the machine is compatible with a wide variety of welding wires and electrodes, adding to its versatility. Whether you're working with stainless steel, aluminum, or mild steel, the SVM148-B can adapt seamlessly.

In conclusion, the Lincoln Electric SVM148-B combines advanced inverter technology with user-friendly features, making it an invaluable addition to any welding setup. Its portability, control options, robust duty cycle, and safety measures set it apart as a reliable and efficient welding solution for professionals and hobbyists alike. Whether for a small workshop or large industrial applications, the SVM148-B meets the demands of modern welding with efficiency and ease.
