2. Mounting the Saw Blade
(1) Thoroughly remove any sawdust which has accumulated
on the spindle, bolt and washers.
(2) For saw blades with hole diameters of 20 mm and 30
mm, as shown in Fig. 8-1, the side of Washer (A) with
a projected center the same diameter as the inner
diameter of the saw blade and the concave side of
Washer (B) must be fi tted to the saw blade sides.
For saw blades with a hole diameter of 15.9 mm, as
shown in Fig. 8-2, the concave side of Washer (A) and
the concave side of Washer (B) must be fi tted to the saw
blade sides.
*
If the saw blade supplied with your circular saw has
a hole diameter of 15.9 mm, only saw blades with
the same size hole diameter can be fi tted to your
circular saw.
*
Washer (A) is supplied for 2 types of saw blades
with the hole diameters of 20 mm and 30 mm.
(When buying the Circular Saw, one type of washer
(A) is supplied.)
In case the hole diameter of your saw blade does
not correspond to that of washer (A), please contact
the shop where you purchased the Circular Saw.
(3) To assure proper rotation direction of the saw blade, the
arrow direction on the saw blade must coincide with the
arrow direction on the saw cover.
(4) Using the fi ngers, tighten the hexagonal-socket bolt
retaining the saw blade as much as possible. Then
depress the lock lever, lock the spindle, and thoroughly
tighten the hexagonal-socket bolt.

MAINTENANCE AND INSPECTION
1. Inspecting the saw blade
Since use of a dull saw blade will degrade effi ciency and
cause possible motor malfunction, sharpen or replace
the saw blade as soon as 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
For your continued safety and electrical shock
protection, carbon brush inspection and replacement
on this tool should ONLY be performed by a Hitachi
Authorized Service Center.
5. Replacing supply cord
If the replacement of the supply cord is necessary, this
has to be done by the manufacturer of this agent in
order to avoid a safety hazard.
6. Adjusting the base and saw blade to maintain
perpendicularity (only aluminum base type)
The angle between the base and the saw blade has been
adjusted to 90°, however should this perpendicularity be
lost for some reason, adjust in the following manner:
(1) Turn the base face up (Fig. 9) and loosen the wing-bolt
(Fig. 5).
(2) Apply a square to the base and the saw blade and
turning the slotted set screw with a slotted-head
screwdriver, shift the position of the base to produce
the desired right angle.
