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. Inspecting the retainer
The retainer may become loose due to excessive use.
Always, pay attention to its proper functioning to securely
hold the accessory shank portion. If any wear and tear
is found, bring this Demolition Hammer to an authorized
service center for maintenance service.
4. 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.
5. 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.
6. Replacing carbon brushes
Loosen the screws (Hexagon socket hd. bolt M4×12)
of the cap covers, then remove the cap covers (Fig. 9).
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.
7. 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.
