MAINTENANCE AND INSPECTION
CAUTION
Be sure to turned off the switch and remove the
Thickness
battery before maintenance and inspection.
(mm)
1. Inspecting the blade
Continued use of a dull or damaged blade will
2.5 – 6
result in reduced cutting efficiency and may cause
overloading of the motor. Replace the blade with
a new one as soon as excessive abrasion is noted.
2.5 – 6
2. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure
2.5 – 6
that they are properly tightened. Should any of the
screws be loose, retighten them immediately. Failure
2.5 – 6
to do so could result in serious hazard.
3. Maintenance of the motor
The motor unit winding is the very "heart" of the
2.5 – 6
power tool. Exercise due care to ensure the winding
does not become damaged and/or wet with oil or
2.5 – 6
water.
4. Inspecting the carbon brushes (Fig. 31)
The motor employs carbon brushes which are
Below 3.5
consumable parts. Since and excessively worn
carbon 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
100
keep carbon brushes clean and ensure that they
100
slide freely within the brush holders.
NOTE
100
When replacing the carbon brush with a new one,
be sure to use the Hitachi Carbon Brush Code No.
