MOUNTING AND DISMOUNTING THE SAW
BLADE
CAUTION
To avoid serious accident, ensure the switch is in the OFF
position, and the power source is disconnected.
1. Dismounting the saw blade
(1) Loosen the knob and slightly reduce the cutting depth
from maximum. (
Fig. 2
)
(2) Place the Circular Saw as shown in
Fig. 16
.
(3) Depress the lock lever, lock the spindle, and remove the
hexagonal-head bolt with the box wrench.
(4) While holding the lower guard lever to keep the lower
guard fully retracted into the saw cover, remove the saw
blade.
2. Mounting the saw blade
(1) Loosen the knob and slightly reduce the cutting depth
from maximum. (
Fig. 2
)
(2) Thoroughly remove any sawdust which has accumulated
on the spindle, bolt and washers.
(3) As shown in
Fig. 17
, 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.
(4) 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.
(5) Using the
fi
ngers, tighten the hexagonal-head bolt
retaining the saw blade as much as possible. Then
depress the lock lever, lock the spindle, and thoroughly
tighten the bolt.
CAUTION
After having attached the saw blade, recon
fi
rm that the lock
lever is
fi
rmly secured in the prescribed position.
MAINTENANCE AND INSPECTION
1. Inspecting the saw blade
Since use of a dull saw blade will degrade e
ffi
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. Inspecting the carbon brushes (Fig. 18)
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.
CAUTION
○
When replacing the new carbon brushes, always use
genuine HiKOKI carbon brushes with the number
speci
fi
ed in the drawing.
○
For models C6BUY and C7BUY, the brake may not work
if other than the speci
fi
ed carbon brushes are used.
When the brake becomes ine
ff
ective, replace the
carbon brushes with new ones.
4. Replacing carbon brushes
Disassemble the brush caps with a slotted-head
screwdriver. The carbon brushes can then be easily
removed.
5. 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.
6. Adjusting the base and saw blade to maintain
perpendicularity
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. 19
) and loosen the lever and
wing-bolt. (
Fig. 3 (A), Fig. 3 (B)
)
(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.
7. Service parts list
CAUTION
Repair,
modi
fi
cation and inspection of HiKOKI Power
Tools must be carried out by a HiKOKI Authorized
Service Center.
This Parts List will be helpful if presented with the tool to
the HiKOKI Authorized Service Center when requesting
repair or other maintenance.
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
MODIFICATIONS
HiKOKI Power Tools are constantly being improved
and modi
fi
ed to incorporate the latest technological
advancements.
Accordingly, some parts may be changed without prior
notice.
NOTE
Due HiKOKI’s continuing program of research and
development, the speci
fi
cations herein are subject to
change without prior notice.
