Alright. So today, we're going to have Mr. Oku show us how to use a circular saw. First, some important safety points.
0:07
The key points are: how to avoid kickback, and the basic usage of a cordless circular saw. As it is, the blade won't spin.
0:22
You need to press the safety lock button first, then pull the trigger. Next, the depth adjustment lever is located here.
0:31
At full depth, it can cut about 45mm. At full capacity, that's 125mm — so about 4.5cm?
0:39
Yes, 4.5cm. So, the best practice is to adjust the depth according to the material you're cutting.
0:49
Set it so the blade sticks out just a little beyond the material — that's the ideal setting.
0:57
Now, this is how you cut in a straight line. Push the front lever forward, then turn the rear lever,
1:09
and the blade tilts — up to about 45 degrees, like this. When tilted, the maximum cutting depth becomes shallower.
1:28
At 45 degrees, you can't cut through the full thickness. This is a 7-inch saw.
1:37
There's another function — with this lever here, push the front lever forward and tilt it the opposite way.
1:48
Tilt it in reverse — sideways, like this.
2:05
That way, you can make cuts near edges or in tight spots where something is in the way — it's called a bevel cut.
2:28
Also, if you remove the front part of the base plate,
2:43
you can make edge cuts very close to zero clearance.
2:53
To put it back, just snap it in. Oh, and let me explain kickback.
3:04
Kickback — let's demonstrate it once.
3:11
Be careful — this is the kickback demonstration.
3:20
First, start spinning the blade,
3:26
then begin cutting —
3:31
and it slides through smoothly. But if you press against the material and then suddenly force it,
3:39
— that's kickback. Exactly. Another situation is when cutting a board at 90° freehand — that's fine normally.
3:58
But if you support the board this way and cut in the middle, that's also dangerous — it causes kickback like this.
4:12
Whoa, that was startling! That's what happens. Please don't use it that way.
4:21
One more thing — wood grain direction. Wood has a grain direction based on how it grew.
4:34
Cutting perpendicular to the grain is easier. Cutting parallel to the grain creates more friction, which can heat up the blade and cause it to wander.
4:58
That's all! Thank you. That was scary!
