If the base is slanted (45 degrees), use the small front scale as the guide (Fig. 15, Fig. 24).

(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.
CAUTION
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.
11 Otherwise, the motor can get locked.
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. 25.

(2)Depress the lock lever, lock the spindle, and remove the Hex. bolt and washer (B) 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 (Fig. 26).

2.Mounting the Saw Blade
CAUTION
If the hex. bolt is worked using other tools than the provided hex. bar 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. 27, 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.
(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 hex. bolt retaining the saw blade as much as possible. Then depress the lock lever, lock the spindle, and thoroughly tighten the hex. bolt.
CAUTION
After having attached the saw blade, reconfirm that the lock lever is firmly secured in the prescribed position.
