MAINTENANCE AND INSPECTION
1. Inspecting the hex-socket (or bit)
Since continued use of a worn hex-socket (bit) will
damage screw heads, replace the hexsocket (bit)
with a new one as soon as excessive wear is
noticed.
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.9)
The motor employs carbon brushes which are
consumable parts. Since an excessively worn carbon
brush can result in motor trouble, replace the carbon
brushes with new ones having the same carbon
brush No. shown in the figure when they become
worn to or near the “wear limit”. In addition, always
keep carbon brushes clean and ensure that they
slide freely within the brush holders.
5. Replacing carbon brushes (Fig.10)
Disassembly:
(1) Loosen the three screws, and remove the handle
cover.
(2) Lift the brush holder gently with a screwdriver or
the like, and remove it from the housing while
depressing the carbon brush. Be careful not to
excessively pull the lead wire.
(3) Remove the carbon brushes from the brush holders.
Assembly
(1) Insert the new carbon brushes into the brush holders.
(2) Insert the brush holders together with the carbon
brushes into the brush holder chambers in the
housing.
(3) Ensure that the lead wire and other parts are properly
positioned, and that there is no possibility of the
lead wire coming in contact with the armature or
other moving parts.
(4) Reinstall the handle cover while ensuring that the
internal wiring does not become pinched between
the handle cover and the housing, and secure the
handle cover with the three screws.
CAUTIONS
⅜ Be sure to follow the above assembly procedures
exactly. Should the internal wiring contact the
armature or become pinched between the handle
cover and housing, a serious risk of electric shock
to the operator would be created.
⅜ Do not tamper with parts other than those necessary
to effect carbon brush replacement.

Due to HITACHI’s continuing program of research and
development, the specifications herein are subject to
change without prior notice.
