SELECTION OF BLADES
To ensure maximum operating effi 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 3-5.

MAINTENANCE AND INSPECTION
CAUTION

before maintenance and inspection.
(mm)
1. Inspecting the blade
Continued use of a dull or damaged blade will result in
2.5 – 6
reduced cutting effi 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
2.5 – 6
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
2.5 – 6 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
2.5 – 6
become damaged and/or wet with oil or water.
4. Inspecting the carbon brushes (Fig. 12)
The motor employs carbon brushes which are
consumable parts. Since and excessively worn carbon
Below 3.5
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
Below 3.5
brushes clean and ensure that they slide freely whithin
the brush holders.
NOTE
When replacing the carbon brush with a new one, be
2.5 – 6
sure to use the HiKOKI Carbon Brush Code No. 999068.
5. Replacing carbon brushes (Fig. 12)
Take out the carbon brush by fi rst removing the brush
2.5 – 6
cap and then hooking the protrusion of the carbon brush
with a fl at head screw driver, etc.
When installing the carbon brush, choose the direction
100
so that the nail ⓑ of the carbon brush agrees with the
100 contact portion ⓒ outside the brush tube. Then push it in
with a fi nger. Lastly, install the brush cap.
