MAINTENANCE AND INSPECTION

WARNING:
To avoid an accident or personal injury, always confirm that
the trigger switch is turned OFF and the power plug has been
disconnected from the receptacle before performing any
maintenance or inspection of this tool.
1. Inspecting the saw blade
Always replace the saw blade immediately upon the first sign of
deterioration or damage.
A damaged saw blade can cause personal injury and a worn saw blade
can cause ineff ective operation and possible overload to the motor.
CAUTION:
Never use a dull saw blade. When a saw blade is dull, its resistance
to the hand pressure applied by the tool handle tends to increase,
making it unsafe to operate the power tool.
2. Inspecting the lever
If the M6 hexagonal head bolts (2) are loose, align the sides of the fence
and saw blade with the steel square. After adjusting the saw blade and
fence to a ninety-degree angle, tighten the lever securing hexagonal head
bolts (2).

3. Inspecting the carbon brushes (Fig. 36 and Fig. 37)
The carbon brushes in the motor are expendable parts.
If the carbon brushes become excessively worn, motor trouble might
occur.
Therefore, inspect the carbon brushes periodically and replace them
when they have become worn to the wear limit line as shown in Fig. 36.
Also, keep the carbon brushes clean so that they will slide smoothly within
the brush holders.
The carbon brushes can easily be removed after removal of the brush
caps (see Fig. 37) with a slotted (minus) screwdriver.
NOTE:
When replacing the carbon brushes, use only Hitachi carbon
brushes having "38" in the last two digit of its Code No. (see
Fig. 36). If you use other carbon brushes, the electric brake will
not operate.
