6. Press the “GLOW PLUG” button to pre- heat the cylinders per the following table:

Ambient Temperature

Pre-Heat Time

 

 

 

 

Above 50°F (10°C)

NOT REQUIRED

 

 

50°F (10°C) to 23°F(-5°C)

Approximately 5 seconds

 

 

Below 23°F (-5°C)

Approximately 10 seconds

 

 

CAUTION

Never press the Glow Plug button continuously for more than 20 seconds.

7.Release the “GLOW PLUG” button and press the “START” button to crank the engine. Release when the engine starts.

8.Check that the indicator lights are off. If not, imme- diately stop the engine and investigate the indicat- ed problem.

9.Allow the engine to warm up at low idle speed for several minutes before applying a load and/or switching to high idle. Allow a longer warm up time in cold weather.

NOTE: If the engine fails to start in 60 seconds or stops running, the “ENGINE” switch must be switched to “OFF” and then switched back to “ON” before attempting to restart the engine. This resets the engine protection circuit.

COLD WEATHER STARTING AND OPERATION

The Kubota engine used in the Ranger 300 can be started in temperatures as low as 5°F (-15°C). At tem- peratures below 23°F (-5°C), it is recommended that No. 1D diesel fuel be used in place of No. 2D. Allow engine to warm up before applying a load or switching to HIGH idle.

STOPPING THE ENGINE

1.Remove all welding and generator power loads and let the engine cool by running it for several minutes at low idle.

2.Stop the engine by placing the Engine Switch in the “OFF” position. This turns off the fuel solenoid. You can also stop the engine by turning off the fuel valve located on the fuel filter housing.

BREAK-IN PERIOD

Any engine will use a small amount of oil during its “break-in” period. For the diesel engine on the RANGER 300, break-in is about 50 running hours.

Check the oil every four hours during break-in. Change the oil after the first 50 hours of operation, every 100 hours thereafter. Change the oil filter at the second oil change.

During break-in, subject the RANGER 300 to moderate loads. Avoid long periods running at idle. Before stopping the engine, remove all loads and allow the engine to cool several minutes.

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.
