In other words, as you look at the head of the bolt, turn it left, or
counterclockwise to loosen. Clockwise tightens.
I know that. (I've known that since I was 6**.)
It's how to get the impact driver to go that way when I hit it with a
hammer!

How do I use an impact wrench?
Which way should it turn when I'm compressing it if I am about to
to
use it to unscrew a bolt or screw? Which direction are you looking
from it?
If I push the front of wrench back into the back of the wrench it
turns either clockwise or counterclockwise, when looked at from the
heal of the wrench, depending on the setting. (The opposite of
course when looked at from the tip of the wrench)
Which way should it turn if I want to use it to unscrew a bolt or
screw? Which way are you looking from it?
I'm trying to unscrew the screws holding on the oil filter of my
recently acquired 69 Honda, not run for 35 years. Also the starter
motor cover. So I can clean and oil them respectively.
I have this problem every time I need to use this wrench and I
figure
it out, but since I'm over 50, or maybe since I was 20, I can't
remember from one time to the next! This time, I think I have it,
but
none of 5 screws will budge!
Press the driver bit tightly into the screw recess (or otherwise hold
the
bit), turn the driver hard left (counterclockwise) until it clicks
around
in
that direction. While holding the driver tightly in this manner (like
you
are trying to loosen the screw) hit the top of the driver. If you need
to
repeat, just be sure you have the driver clicked counterclockwise and
put
as
much turning force on it as you reasonably can while hitting the end.
You
have to be trying to turn the screw when you hit the driver for it to
work.

That's not true. That is the whole reason there is a CW and CCW setting
on
the tool. When you hit it with a hammer, it turns one direction or the
other
without regard to the tension you put in either direction, or none at
all.
The advice to put it on a hard slick surface, like a tool box, and press
on
it, is a good way to see which way it is going.
Ok, but I just can't see how or why you would set the tool to CCW and hit
it
while holding CW pressure or no pressure on it. My Snap-On driver has no
CW
or CCW markings or settings, you just turn it the direction you want the
screw to go and hit it. Maybe others are different.

I'm not saying you shouldn't put tension on it. I put tension in the
direction it is going too. I'm just saying that if you have it set for CW,
even if you are putting pressure on it in the CCW direction to loosen a
screw, when you hit it with the hammer, it will turn CW, tightening it. You
can't overcome the direction it is set necessarily.
Mine is always set for CCW, since I have never used it for, nor have I
found, reverse thread screws, so I don't have to remember which way it is
set.
