WARNING

DO NOT RUN THE ENGINE AT EXCESSIVE SPEEDS. The maximum allowable high idle speed for the RANGER 300 is 3700 RPM, no load. Do NOT adjust the governor screw on the engine. Severe personal injury and damage to the machine can result if it is operated at speeds above the maximum rated speed.

Read and understand all safety instructions included in the Kubota instruction manual that is shipped with your RANGER 300.

BEFORE STARTING THE ENGINE

Check the engine oil level:

See Figure D.1 for location of dipstick.

1. Be sure the machine is on a level surface.

NOTE: DO NOT allow the RANGER 300 to run out of fuel. If it does, you will have to bleed the injection sys- tem. See the Maintenance section of this manual and the Engine Operator’s Manual for instructions on bleeding the fuel injection system.

CAUTION

USE DIESEL FUEL ONLY

Purchase diesel fuel in quantities that will be used within 30 days, to assure freshness.

STARTING THE ENGINE

CAUTION

Remove all loads connected to the AC power recepta- cles and the welder before starting the diesel engine.

2.Remove the engine oil dipstick and wipe it with a clean cloth. Reinsert the dipstick and check the level on the dipstick.

3.Add oil (if necessary) to bring the level up to the full mark. Do not overfill.

4.Replace the dipstick.

Check and fill the engine fuel tank:

WARNING

DIESEL fuel can cause fire or explosion.

•Stop engine when fueling.

•Do not smoke when fueling.

•Do not overfill tank.

•Keep sparks and flame away from tank.

1.Remove the fuel tank cap.

2.Fill the tank approximately 4 inches (100 mm) from the top of the filler neck to allow for fuel expansion (observe the fuel gauge.) DO NOT FILL THE TANK TO THE POINT OF OVERFLOW.

3.Replace the fuel tank cap and tighten securely.

1.Open the engine compartment door and check that the fuel shutoff valve located above the clear plas- tic fuel filter housing is in the open position (lever in the vertical position). See Figure B.3.

FIGURE B.3

2.Check for proper level of coolant in the plastic reserve overflow tank. The level should be between the full and the low marks.

3.Check for proper oil level on the oil dipstick. Close engine compartment door.

4.Set “IDLER” switch to “AUTO”. /

5.Set the “ENGINE” switch to “ON”. Observe that both the oil pressure light and battery charger light are on. Check the fuel gauge to make sure that there is an adequate fuel level. (NEVER ALLOW THE RANGER 300 D/DLX TO RUN OUT OF FUEL.)

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.
