(4) Move the marked wood chip to the front of the base,
and turn the parallelism adjustment screw so that
the marking corresponds to the base side (Fig. 6).
(5) After adjustment, fasten the mounting screws tightly
in place.
NOTE
Parallelism may be slightly faulty if the cutting depth is
adjusted after parallelism adjustment.
5. Using the dust collector
The dust collector collects sawdust when the vacuum
cleaner is attached to the power tool.
Remove the lever attached to the power tool and attach
lever (short type).
Attach the dust collector to the power tool with the M4
screw (Fig. 10).
CUTTING PROCEDURES
1. Place the saw body (base) on the lumber, and align the
cutting line with the saw blade at the front scale (Fig. 7).
2. Turn ON the switch before the saw blade contacts the
lumber. The switch is turned ON when the trigger is
squeezed, and turned OFF when the trigger is released.
CAUTIONS
Prior to cutting operation, make sure the material you are
going to cut. If the material to be cut is expected to generate
harmful / toxic dusts, make sure the dust bag or appropriate
dust extraction system is connected with dust outlet tightly.
Wear the dust mask additionally, if available.
○ Before starting to saw, confirm that the saw blade has
attained full-speed revolution.
○ Should the saw blade stop or make an abnormal noise
while operating, promptly turn OFF the switch.
○ Always take care in preventing the power cord from
coming near to the revolving saw blade.
○ Using the circular saw with the saw blade facing
upwards
or
sideways
uncommon applications should be avoided.
○ When cutting materials, always wear protective
glasses.
○ When finished with a job, pull out the plug from the
receptacle.
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) Set the cutting volume at maximum, and place the
Circular Saw as shown in Fig. 8.
(2) Depress the lock lever, lock the spindle, and remove the
hexagonal-head bolt with the box wrench.
(3) 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) Thoroughly
remove
accumulated on the spindle, bolt and washers.
(2) As shown in Fig. 9, 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.
*
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.)

is
very
hazardous. Such
any
sawdust
which
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 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. 12)
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. 11) and loosen the wing-bolt
(Fig. 3).
(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.
has
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. 13).
Dust or particle accumulation in the motor can result in
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.
