Air Removal, Cleaning the Fuel Strainer

MAINTENANCE

Air Removal

If air enters the fuel injection system of a diesel engine, starting becomes impossible. After running out of fuel, or after disassembling the fuel system, bleed the system according to the following procedure.

To restart after running out of fuel, turn the switch to the ON position for 15-30 seconds. Try again, if needed.This unit is equipped with an automatic air bleeding system.

Cleaning the Fuel Strainer

Clean the fuel strainer if it contains dust or water. Remove dust or water in the strainer cap and wash it in gasoline. Securely fasten the fuel strainer cap so that fuel will not leak. Check the fuel strainer every 200 hours of operation or once a month.

Check Oil Level

Check the crankcase oil level prior to each use, or when the fuel tank is filled. Insufficient oil may cause severe damage to the engine. Make sure the generator is level. The oil level must be between the two notches on the dipstick as shown in Figure 30.

Replacing Oil Filter

Detach the oil filter by loosening center bolt and remove the element together with the filter body.

Apply a film of oil to the gasket for the cartridge.

Install the filter body together with the element and fix them by tightening the center bolt.

After the oil cartridge has been replaced, the engine oil will drop slightly. Run the engine for a while and check for leaks before adding more oil if needed. Clean excessive oil from engine.

Replacing Fuel Filter

Replace the fuel filter cartridge with new one every 400 hours or so.

Loosen the drain plug at the lower top of the fuel filter. Drain the fuel in the fuel body together with the mixed water. DO NOT spill the fuel during disassembly.

Vent any air.

Feed Pump Strainer Cleaning

The strainer is incorporated in the feed pump inlet side joint bolt. Clean the strainer with compressed air and rinse it in the fuel oil.

Flushing Out Radiator and Replacing Coolant

Open both cocks located at the crankcase side and at the lower part of the radiator and drain coolant.Open the radiator cap while draining. Remove the overflow tank and drain.

Check hoses for softening and kinks. Check clamps for signs of leakage.

Flush the radiator by running clean tap water through radiator until signs of rust and dirt are removed.DO NOT clean radiator core with any objects, such as a screwdriver.

Tighten both cocks and replace the overflow tank.

Replace with coolant (Table 12 for correct mixture).

Close radiator cap tightly.

CAUTION

Allow engine to cool when flushing out radiator.Flushing the radiator while hot could cause serious burns from water or steam.

Generator Storage

For longe term storage of the generator the following is recommended:

Fill the fuel tank completely. Treat with a fuel stabilizer if necessary.

Completely drain the oil from the crankcase and refill if necessary with fresh oil.

Clean the entire generator, internal and external.

Cover the generating set and store in a clean, dry place.

Disconnect the battery.

Make sure engine coolant is at proper level.

If generator is mounted on a trailer, jack trailer up and place on block so tires do touch the ground or remove tires.

DCA25USI2XF, DCA25USIXF specifications

Multiquip is a renowned name in the construction and industrial equipment sector, known for delivering high-performance generators that cater to various power needs. Two standout models in their lineup are the DCA25USIXF and DCA25USI2XF, both designed for reliability, efficiency, and versatility.

The Multiquip DCA25USIXF is a compact, industrial-grade diesel generator that delivers a powerful 25 kVA, making it ideal for construction sites, outdoor events, and emergency backup applications. This model is powered by a robust Yanmar diesel engine, which ensures high fuel efficiency and low emissions, adhering to stringent environmental standards. The DCA25USIXF features an advanced digital control panel, providing users with an intuitive interface for monitoring performance, voltage output, and operational status. Its sound-attenuated enclosure significantly reduces noise levels, making it suitable for use in noise-sensitive areas.

On the other hand, the DCA25USI2XF model takes power generation a step further by offering dual voltage capabilities, allowing users to switch between 120V and 240V outputs. This flexibility makes it highly versatile, catering to a broader range of tools and equipment. Like the DCA25USIXF, the DCA25USI2XF is also equipped with Yanmar’s reliable diesel engine, which contributes to its durability and long service life. Both models come with a heavy-duty frame to withstand tough conditions, ensuring durability on job sites.

The technology implemented in these generators includes automatic voltage regulation (AVR), which stabilizes voltage output, protecting sensitive equipment from power surges. Additionally, the generators feature a low oil shutdown system, which prevents engine damage by automatically shutting down the generator when oil levels are low. This protective measure not only enhances the longevity of the generator but also contributes to safer operation.

In terms of portability, both models are equipped with rugged wheels and a lifting eye, facilitating easy transportation to various job sites. With their combination of power, efficiency, and advanced features, the Multiquip DCA25USIXF and DCA25USI2XF generators are excellent choices for professionals seeking reliable power solutions in demanding environments. Whether for construction, events, or standby power, these generators deliver exceptional performance tailored to meet diverse needs.
