Selecting accessories ―4

*1 If the tool’s entire notched portion isn’t inserted beyond

the front cover’s end surface, lightly tap the tool using a

hammer or other object to insert it.

*2 Operate this Demolition Hammer by utilizing its empty

weight. The performance will not be better even if it is

pressed or thrust forcibly against the work surface.

Hold this Demolition Hammer with a force just suﬃ cient

to counteract the reaction.

CAUTION

Sometimes the tool does not begin the striking motion

even when the motor rotates because the oil has become

thick.

If the tool is used at low temperature or if it is used after a

long time idle, the tool should be used running in for ﬁ ve

minutes in order to warm it up.

OIL FEEDING

CAUTION

Prior to oil feeding, always disconnect the plug from the

receptacle.

Since an oil chamber is built in this Demolition Hammer, it

can be used for approximately 20 days without replenishing

lubrication oil, assuming that the Hammer is used

continuously 3–4 hours daily.

Feed oil into the oil tank as described below before using this

Demolition Hammer. (See Figs. 6 and 7)

1. Just before no oil is visible in the oil gauge window when

the power tool is held upright, feed oil without fail.

2. Before feeding oil, use the provided wrench to remove

the oil gauge.

Be careful not to lose the rubber packing attached below

the oil gauge.

3. Check the oil level once a day, conﬁ rming that oil is ﬁ lled.

4. After feeding oil, securely clamp the oil gauge.

NOTE

As an optional accessory, oil for the Demolition Hammer

(one liter) is sold separately. Use this oil when oil in the

tank is depleted.

MAINTENANCE AND INSPECTION

CAUTION

Be sure to switch OFF and disconnect the attachment

plug from the receptacle to avoid a serious accident.

1. Inspecting accessories

Since use of a dull accessory, such as a bull point, a

cutter, etc. will degrade eﬃ ciency and cause possible

motor malfunction, sharpen or replace with a new one as

soon as abrasion is noted.

2. Inspecting the mounting screws

Regularly inspect all mounting screws and ensure that

they are properly tightened. Should any of the screws be

loose, retighten them immediately. Failure to do so could

result in serious hazard.

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. 8)

The Motor employs carbon brushes which are

consumable parts. When they become worn to or near

the “wear limit” ⓐ, it results in motor trouble.

When an auto-stop carbon brush is equipped, the motor

will stop automatically. At that time, replace both carbon

brushes with new ones which have the same carbon

brush Numbers ⓑ shown in the Fig. 8. In addition,

always keep carbon brushes clean and ensure that they

slide freely within the brush holders.

5. Replacing carbon brushes

Loosen the screws (Hexagon socket hd. bolt M4×12)

of the cap covers, then remove the cap covers. After

removing the brush caps, the carbon brushes can be

removed.

After replacing the carbon brushes, tighten the brush

caps, then mount the cap covers securely.

6. Replacing supply cord

If the replacement of the supply cord is necessary, it has

to be done by HiKOKI Authorized Service Center to avoid

a safety hazard.

CAUTION

In the operation and maintenance of power tools, the

safety regulations and standards prescribed in each

country must be observed.
