ADJUSTING THE SAW PRIOR TO USE
1. Adjusting the cutting depth
As shown in Fig. 3, hold the handle with one hand
while loosening the knob with the other.
The cutting depth can be adjusted by moving the
base to the desired position. In such manner adjust
the cutting depth and then securely retighten the
knob.
2. Adjusting the angle of inclination
As shown in Fig. 4 (A), Fig. 4 (B) by loosening the
wing-nut on the incline gauge and the wing-bolt on
the base, the saw blade may be inclined to a
maximum angle of 45° in relation to the base. After
having completed the adjustment, reconfirm that
the wing-nut and the wing-bolt are firmly tightened.
3. Regulating the guide (Fig. 5)
The cutting position can be regulated by moving
the guide to the left or right after loosening its
wingbolt. The guide may be mounted on either the
right or left side of the tool.
4. Adjusting the guide piece
On the circular saw, it is possible to make fine
adjustment of the fixing position of the guide piece,
where the saw blade and the premarked line are
to be aligned.
When the saw is shipped from the factory, the
linear portion of a front scale on the guide piece
is aligned with the central position of the saw blade
(Fig. 6).
Loosen the fixed M4 screw on the guide piece,
should the fixing position be wrong, and make
necessary adjustment of the position.
CUTTING PROCEDURES
1. Place the base on the material, then align the
premarked line and the sawblade with the guide
piece front scale section at the front of the base
(Fig. 6).
When the base is not slanted, use the large cutout
as the guide (Fig. 6, Fig. 7 (A)).
If the base is slanted (45 degrees), use the small
front scale as the guide (Fig. 6, Fig. 7 (B)).
2. Ensure that the switch is turned to the ON position
before the saw blade comes in contact with the
lumber. The switch is turned ON when the trigger
is squeezed; and OFF when the trigger is released.
3. Moving the saw straight at a constant speed will
produce optimum cutting.
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.
A coating of PFTE is applied to the bases of the C9BA2
type. Be careful not to press too hard on the unit body
since this tends to place a heavy load on the motor.
Using a gentle pressure will make the piece slide easier
and allow cutting with less force. Trying to cut wood that
is covered with hard particle material such as sand or
metal chips tends to easily scratch damage the surface
coating so use caution.
7
Before starting to saw, ensure that the saw blade
has reached full speed revolution.
Should the saw blade be stopped or made an
abnormal noise during operation, turn off the switch
immediately.
Always take care in preventing the power cord from
coming near the revolving saw blade.
Using the circular saw with the saw blade facing
upwards or sideways is very hazardous. Such
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-socket bolt with the Hex. bar 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 any sawdust which has
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 16 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 fingers, 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 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.
