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. 17.
(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
accumulated on the spindle, bolt and washers.
(3) As shown in Fig. 18, 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 fitted 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 fingers, 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, reconfirm that the lock
lever is firmly secured in the prescribed position.

MAINTENANCE AND INSPECTION

1. Inspecting the saw blade
Since use of a dull saw blade will degrade efficiency
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. 19)
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 figure 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
specified in the drawing.
4. Replacing carbon brushes
Disassemble the brush caps with a slotted-head
screwdriver. The carbon brushes can then be easily
removed.
5. Replacing supply cord
If the supply cord of Tool is damaged, the Tool must be
returned to HiKOKI Authorized Service Center for the
cord to be replaced.

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. 20) and loosen the lever and
wing-bolt. (Fig. 4 (A), Fig. 4 (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. Motor unit maintenance
The motor winding is an important part of this tool.
Avoid damaging and be careful to avoid contact with
cleaning oil or water.
After 50 hours of use, clean the motor by blowing into
the ventilation holes of the motor housing with dry air
from an air gun or other tool (Fig. 21).
Dust or particle accumulation in the motor can result in
has
damage.
8. Inspecting and maintaining the lower guard
Always make sure that the lower guard moves
smoothly.
In the event of any malfunction, immediately repair the
lower guard.
For cleaning and maintenance, use an air gun or other
tool to blow clean the space between the lower guard
and gear cover as well as the rotation part of the lower
guard with dry air (Fig. 21).
Doing so is effective for the emission of chips or other
particles.
Accumulation of chips or other particles around the
lower guard may result in malfunction or damage.
WARNING
To prevent dust inhalation or eye irritation, wear
protective safety goggles and a dust mask when
using an air gun or other tool to clean the lower guard,
ventilation holes or other parts of the product.
Ensure smooth movement
