State of lamp Battery Remaining Power
The battery remaining power
is enough.
The battery remaining power
is a half.
The battery remaining power
is nearly empty.
Re-charge the battery soonest
possible.
As the remaining battery indicator shows somewhat
differently depending on ambient temperature and
battery characteristics, read it as a reference.
NOTE:
Do not give a strong shock to the switch panel or
break it.It may lead to a trouble.
To save the battery power consumption, the
remaining battery indicator lamp lights while
pressing the remaining battery indicator switch.
3. Cutting procedures
CAUTION
Recheck that the saw blade is securely clamped.
Confirm that the wing nut for adjusting the slot
depth, the wing bolt for adjusting the angle of
inclination are securely clamped.
(1) Place the base on the material, then align the
premarked line and the sawblade with the notch
at the front of the base (Fig. 15).
When the base is not slanted, use the large cutout
as the guide (Fig. 15, Fig. 19(A)).
If the base is slanted (45 degrees), use the small
front scale as the guide (Fig. 15, Fig. 19(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.
Moving the saw straight at a constant speed will
produce optimum cutting.
CAUTIONS
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.
When finished with a job, pull out the battery from
the main body.
Twisting and forcibly pressing the saw during cutting
can result in unreasonable pressure on the motor,
so try to go straight quietly.
In the situation where the circular saw is continuously
operated while replacing the battery with stocked
spare batteries one after another, the motor tends
to overheat. Therefore, whenever the housing
becomes hot, give the saw a break for a while.
Avoid cutting operation in a state where the base
bottom is afloat from the material being cut.
Otherwise, the motor can get locked.

Table 4 MOUNTING AND DISMOUNTING THE SAW
BLADE
CAUTION
To avoid serious accident, ensure the switch is in
the OFF position, and pull out the battery.
1. Dismounting the saw blade
(1) Set the cutting volume at maximum, and place the
Circular Saw as shown in Fig. 20.
(2) Depress the lock lever, lock the spindle, and remove
the left-hand bolt and washer (B) 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 (Fig. 21).
2. Mounting the Saw Blade
CAUTION
If the left-hand bolt is worked using other tools than
the provided box wrench, excessive tightening and
insufficient tightening may take place resulting in
injury.
(1) Thoroughly remove any sawdust which has
accumulated on the spindle, bolt and washers.
(2) As shown in Fig. 22, 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 spplied.)
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 left-hand bolt retaining
the saw blade as much as possible. Then depress
the lock lever, lock the spindle, and thoroughly
tighten the left-hand bolt.
CAUTION
After having attached the saw blade, reconfirm that
the lock lever is firmly secured in the prescribed
position.

REPLACING LIGHT BULB

CAUTION
Make absolutely sure that the battery is removed
from the main body before replacing the light bulb.
Immediately after the light is turned OFF, the bulb
retains high temperature. Make sure to cool down
the light bulb thoroughly before replacing it so as
to prevent burns.
When replacing the light bulb, check the shape of
base as well as the rating (12 V, 5 W), and then
carry out perfect mounting. Otherwise, the light
bulb can come off and/or cause overheat.
1. Detaching light bulb
(1) Remove the convex part of the light cover from the
concave part of the handle cover, and then pull out
the light cover in the arrow-marked direction as
shown in Fig. 23.
