Frequently Asked Questions - DW25EF(SRP) HITACHI

How do I change the drill bit on the Hitachi DW25EF(SRP)?

Turn the chuck ring counterclockwise to open the jaws. Insert the bit, then tighten the chuck by turning the ring clockwise. Ensure the bit is centered and secure. For keyless chucks, no key is needed.

What is the maximum drilling capacity of the DW25EF(SRP)?

The maximum drilling capacity in steel is 13 mm (1/2 in), and in wood it is 25 mm (1 in). Use appropriate bits for materials.

Can I use this drill for screwdriving?

Yes, the DW25EF(SRP) has a variable speed trigger that allows controlled screwdriving. Use a screwdriver bit and set the torque clutch (if available) to prevent overdriving.

How do I adjust the speed of the drill?

The speed is controlled by the trigger pressure: light pressure for low speed, full pressure for high speed. There is also a speed selector switch (if equipped) for high/low gear ranges.

What safety precautions should I take when using the drill?

Always wear safety glasses and hearing protection. Secure your workpiece. Keep hands away from rotating parts. Unplug the drill when changing bits. Use the side handle for control.

5. Maintenance

MAINTENANCE. REPLACEMENT, OR REPAIR OF THE EMISSION CONTROL DEVICES AND SYSTEM MAY BE PERFORMED BY ANY NONROAD ENGINE REPAIR ESTABLISHMENT OR INDIVIDUAL.

Carburetor adjustment (Fig. 3-1)

! WARNING!

The bit may be spinning during carburetor adjustments.

! WARNING!

Never start the engine without the complete clutch cover and gear case assembled! Otherwise the clutch can come loose and cause personal injuries.

In the carburetor, fuel is mixed with air. When the engine is test run at the factory, the carburetor is adjusted. A further adjustment may be required, according to climate and altitude. The carburetor has one adjustment possibility: T = Idle speed adjustment screw.

Idle speed adjustment (T)

Check that the air filter is clean. When the idle speed is correct, the bit will not rotate. If adjustment is required, close (clockwise) the T-screw, with the engine running, until the bit starts to rotate. Open (counter-clockwise) the screw until the bit stops. You have reached the correct idle speed when the engine runs smoothly in all positions well below the rpm when the bit starts to rotate.

If the bit still rotates after idle speed adjustment, contact HITACHI dealer.

NOTE!

Some models sold areas with strict exhaust emission regulation do not have high and low speed carburetor adjustments. Such adjustments may allow the engine to be operated outside of their emission compliance limits. For these models, the only carburetor adjustment is idle speed.

For models that equipped with low and high speed adjustments; carburetors are pre set at the factory Minor adjustments may optimize performance based on climate, altitude, etc. Never turn the adjustment screws in increments greater than 90 degrees, as engine damage can result from incorrect adjustment If you are not familiar with type of adjustment-assistance HITACHI dealer.

! WARNING!

When the engine is idling the bit must under no circumstances rotate.

Air filter (Fig. 3-2)

The air filter must be cleaned from dust and dirt in order to avoid:

• Carburetor malfunctions.
- Starting problems.
• Engine power reduction.
- Unnecessary wear on the engine parts.
● Abnormal fuel consumption.

Clean the air filter daily or more often if working in exceptionally dusty areas.

Cleaning the air filter

Remove the air filter cover and the filter. Rinse it in warm soap suds. Check that the filter is dry before reassembly. An air filter that has been used for some time cannot be cleaned completely. Therefore, it must regularly be replaced by a new one. A damaged filter must always be replaced.

NOTE!

Saturate the element in 2 cycle oil or the equivalent. Squeeze the element to distribute the oil completely and to remove any excess oil.

Spark plug (Fig. 3-3)

The spark plug condition is influenced by:

• An incorrect carburetor setting.
- Wrong fuel mixture (too much oil in the gasoline)
- A dirty air filter.
- Hard running conditions (such as cold weather).

These factors cause deposits on the spark plug electrodes, which may result in malfunction and starting difficulties. If the engine is low on power, difficult to start or runs poorly at idling speed, always check the spark plug first. If the spark plug is dirty, clean it and check the electrode gap. Readjust if necessary. The correct gap is 0.6 mm (.024"). The spark plug should be replaced after about 100 operation hours or earlier if the electrodes are badly eroded.

NOTE!

In some areas, local law requires using a resistor spark plug to suppress ignition signals. If this machine was originally equipped with resistor spark plug, use same type of spark plug for replacement.

Gear case (Fig. 3-4, 4B)

Apply a good quality lithium based grease through the grease fitting. Lubrication should be applied at 50 hour intervals and more frequent at heavy use.

Fig. 3-5 Fig. 3-6

Fig. 3-7

Fuel filter (Fig. 3-5)

Remove the fuel filter from the fuel tank and thoroughly wash it in solvent. After that, push the filter into the tank completely.

NOTE!

If the filter is hard due to dust and dirt, replace it.

Cleaning the cylinder fins (Fig. 3-6)

When wood chips are caught between cylinder fins, the engine may overheat, resulting in lower output. To avoid this, always keep cylinder fins and fan case clean.

Every 100 Operating hours, or once a year (more often if conditions require), clean fins and external surfaces of engine of dust, dirt and oil deposits which can contribute to improper cooling.

Cleaning the muffler (Fig. 3-7)

Remove the muffler and spark arrestor (if so equipped), and clean out any excess carbon from the exhaust port or muffler inlet every 100 hours of operation.

For long-term storage

Drain all fuel from the fuel tank. Start and let engine run until it stops. Repair any damage which has resulted from use. Clean the unit with a clean rag, or the use of high pressure air hose. Put a few drops of two-cycle engine oil into the cylinder through the spark plug hole, and spin the engine over several times to distribute oil. Cover the unit and store it in a dry area.

Maintenance schedule

Below you will find some general maintenance instructions. For further information please contact HITACHI dealer.

Daily maintenance

• Clean the exterior of the unit.
• Check that the drilling attachment is properly centred, sharp, and without cracks. An offcentred bit induces heavy vibrations that may damage the unit.
• Chock that the drilling attachment is sufficiently tightened.
• Check that nuts and screws are sufficiently tightened.

Weekly maintenance

• Check the starter, especially cord and return spring.
• Clean the exterior of the spark plug.
• Remove it and check the electrode gap.
  Adjust it to 0.6 mm, or change the spark plug.
• Clean the cooling fins on the cylinder and check that the air intake at the starter is not clogged.
• Check that the angle gear is filled with grease up to 3/4.
• Clean the air filter.

Monthly maintenance

• Rinse the fuel tank with gasoline.
• Clean the exterior of the carburetor and the space around it.
• Clean the fan and the space around it.

• Da varneje privijete vpenjalno glavo, postavite 19 mm ključ (1) med gonilo in vpenjalno glavo, da pogonsko os zaklenete. Zaporni vzvod (2) vklopite, nato udarite pritrjeni ročaj vpenjalne glave s kladivom, da bi privili (v smeri urnega kazalca) vpenjalno glavo. (DW25EB(SK)/DW25EB(SKN)/DW25EC (SKN)/DW25ED(KP)/DW25ED(KPN)/DW 25EF (SK)/DW25EF (SKN)) (slika 2-6)

• Da razrahljate vpenjalno glavo, ključ postavite na drugo stran in udarite ročaj vpenjalne glave od te strani, da se vpenjalna glava odvije (nasprotno od urnega kazalca) z zapornim vzvodom. (DW25EB(SK)/DW25EB(SKN)/DW25 EC (SKN)/DW25ED (KP)/DW25ED (KPN)/DW25EF (SK)/DW25EF (SKN)) (slika 2-6B)

• Opomba! Pri DW25EB (SR)/DW25EB (SRN)/DW25EF (SR)/DW25EF (SRN) uporabite ključ vpenjalne glave (3) namesto ročaja vpenjalne glave in privijte ali odvijte z roko namesto, da bi uporabili tehniko udarjanja. Ne udarjajte ob ključ vpenjalne glave. (Slika 2-7, 7B)

• Da namestite ali razrahljate vpenjalno glavo brez ključa, postavite 19 mm ključ (1) med gonilo in vpenjalno glavo, da pogonsko os zaklenete. Zaporno palico (2) iz vrečke z orodjem namestite v vpenjalno glavo in nato palico (2) privijte (v smeri urnega kazalca) ali odvijte (nasprotno od urnega kazalca) s priloženim ključem. (Slika 2-7C)
