SAFETY

GENERAL SAFETY RULES

WARNING:

Read all instructions

Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.

The term “power tool” in all of the warnings listed below refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

SAVE THESE INSTRUCTIONS

1)Work area safety

a)Keep work area clean and well lit.

Cluttered or dark areas invite accidents.

b)Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust.

Power tools create sparks which may ignite the dust of fumes.

c)Keep children and bystanders away while operating a power tool.

Distractions can cause you to lose control.

2)Electrical safety

a)Power tool plugs must match the outlet. Never modify the plug in any way.

Do not use any adapter plugs with earthed (grounded) power tools.

NOTE: When standby for cooling battery, UC18YRL cools the overheated battery by cooling fan.

Regarding the temperature of the rechargeable battery.

The temperatures for rechargeable batteries are as shown in the table below, and batteries that have become hot should be cooled for a while before being recharged.

	Table 3
Rechargeable	Temperatures at which the
batteries	battery can be recharged
EBM1830	32°F — 122°F (0°C — 50°C)

4.Disconnect battery charger from the receptacle.

CAUTION:

Do not pull the plug out of the receptacle by pulling on the cord.

Make sure to grasp the plug when removing from receptacle to avoid damaging cord.

5.Remove the battery from the battery charger. Supporting the battery charger with hand, pull out the battery from the battery charger.

CAUTION:

If the battery is charged while it is heated because it has been left for a long time in a location subject to direct sunlight or because the battery has just been used, the pilot lamp of the charger lights up green. In such a case, first let the battery cool, then start charging.

When the pilot lamp flikers in red (at 0.2–second intervals), check for and take out any foreign objects in the charger’s battery installation hole. If there are no foreign objects, it is probable that the battery or charger is malfunctioning. Take it to your authorized Service Center.

Since the built-in micro computer takes about 3 seconds to confirm that the battery being charged with the charger is taken out, wait for a minimum of 3 seconds before reinserting it to continue charging. If the battery is reinserted within 3 seconds, the battery may not be properly charged.

How to make the batteries perform longer.

Recharge the batteries before they become completely exhausted.

When you feel that the power of the tool becomes weaker, stop using the tool and recharge its battery. If you continue to use the tool and exhaust the electric current, the battery may be damaged and its life will become shorter.

Avoid recharging at high temperatures.

A rechargeable battery will be hot immediately after use. If such a battery is recharged immediately after use, its internal chemical substance will deteriorate, and the battery life will be shortened. Leave the battery and recharge it after it has cooled for a while.

BEFORE USE

Check the work area to make sure that it is clear of debris and clutter.

Clear the area of unnecessary personnel. Ensure that lighting and ventilation is adequate.

8.Switching between the “SAVE“ and the “POWER“ modes

The hammering force of the hammer can be increased or decreased to conform with intended usage, by operating the shift knob as per Fig. 25. Adjust the force to match the usage intended.

“SAVE“ mode

“POWER“ mode

Shift knob

Fig. 25

(1)“SAVE“ mode ... decreased hammering force This can prevent thin drill bits which are less than

4.3mm in diameter, from being bent or broken.

(2)“POWER“ mode ... increased hammering forceThis can be used to speedily and efficiently drill

holes when the drill bits which are being used are greater than 4 mm in diameter.

This can be used to drill holes into wood or metal.

CAUTION:

Do not drill holes in wood with the “SAVE“ mode. There is a likelihood that the motor will burn out because it can easily lock up due to the low power.

MAINTENANCE AND INSPECTION

CAUTION: Pull out battery before doing any inspection or maintenance.

1.Inspecting the drill bits

Since use of a dull tool will cause motor malfunctioning and degraded efficiency, replace the drill bit with a new one or resharpening without delay when abrasion is noted.

2.Check the Screws

Loose screws are dangerous. Regularly inspect them and make sure they are tight.

CAUTION:

Using this power tool with loosened, screws is extremely dangerous.

3.Maintenance of the motor

The motor unit winding is the very “heart” of the power tool.

Exercise due care to ensure the winding does not become damaged and/or wet with oil or water.

4.Inspecting the carbon brushes (Fig. 17)

The motor employs carbon brushes which are consumable parts. Since and excessively worn carbon brush can result in motor trouble, replace the carbon brush with new ones when it becomes worn to or near the “wear limit”. In addition, always keep carbon brushes clean and ensure that they slide freely within the brush holders.

NOTE:

When replacing the carbon brush with a new one, be sure to use the Hitachi Carbon Brush Code No. 328481.

5.Replacing carbon brushes

Take out the carbon brush by first removing the brush cap and then hooking the protrusion of the carbon brush with a flat head screw driver, etc., as shown in Fig. 18.

When installing the carbon brush, choose the direction so that the nail of the carbon brush agrees with the contact portion outside the brush tube. Then push it in with a finger as illustrated in Fig. 19. Lastly, install the brush cap.

CAUTION:

●Be absolutely sure to insert the nail of the carbon brush into the contact portion outside the brush tube. (You can insert whichever one of the two nails provided.)

●Caution must be exercised since any error in this operation can result in the deformed nail of the carbon brush and may cause motor trouble at an early stage.
