SELECTION OF BLADES
To ensure maximum operating e ffi ciency and results, it is
very important to select the appropriate blade best suited to
the type and thickness of the material to be cut.
The blade number is engraved in the vicinity of the mounting
portion of each blade. Select appropriate blades by referring
to Table 1-2 .

MAINTENANCE AND INSPECTION
1. Inspecting the blade
Continued use of a dull or damaged blade will result in
reduced cutting e ffi ciency and may cause overloading of
the motor. Replace the blade with a new one as soon as
excessive 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. 11)
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 fi gure when it becomes worn to or
near the “wear limit” ⓑ . In addition, always keep carbon
brushes clean and ensue that they slide freely within the
brush holders.
5. Replacing carbon brushes (Fig. 11)
Disassemble the brush caps with a slotted-head
screwdriver. The carbon brushes can then be easily
removed.
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.
