Transcripts
Oil is right where it should be
Coolant is right there too
Ok, got it
You guys being good?
That's my favorite way to keep track of oil changes.
Just write it right on the machine somewhere where the operator can see it.
And every time you do it, just keep writing.
In 5/2015 I had 6960
This is the quietest air compressor
I'm missing a fitting up there
and this is bugging me.
It was loose
these are 1/8 NPT.
But even though these threads seem to mesh
properly,
See, that one is bigger
Okay, so it's not that
definitely not.
I'm noticing hoses
that look like that.
So let's just change this now
there's my one to hand to the shop
That one's been changed.
And that one,
It's old, but it's not.
That one's all right.
That line right there, look at that.
five new hoses
Is this O-ring damaged?
Yes, it is
Okay.
That's why that was leaking
O-ring is damaged here
These are high pressure O-rings
They are not from Harbor Freight.
Getting these in here is difficult
Blue, get the Frisbee
Blue, what is that? Get that Frisbee
What?
It's not taking grease,
Not taking it
or sometimes just moving that
pin around is all it takes.
Yeah, it looks like it's taking grease now.
Sounds like that.
That Uncloged it.
I just put a battery in this
The old one didn't really test bad.
Okay,
That goes there
This starter was out of, this is a Cummins engine
so I ordered one out of a and the starter was like expensive
but I ordered one out of a pickup truck, you know, a Dodge pickup with a Cummins
because it looked the same and then it was like a mirror image
of what I needed it to be.
So I made one starter out of two
This is the right one.
Put that big one on
It needed a starter
Usually starters work or they don't.
But in this case, it was not strong enough
I want to keep this forklift inside
I want to put this in this bay but let me get these doors off of here
because if this parked there all the time, you won't able to get in there.
Yeah.
I'm realizing I need to keep an isle open
open, just that I can walk through against these doors here.
Thats in enough
Not tight enough, I’ll put it on “Two”
like this.
That filter looks good
See like that.
I'm not going to use that
It needs to charge longer than 5 minutes.
That ran overnight, till it ran out of gas
recently.
Put that pipe in.
That's working good But there is a few little potholes here.
All right.
Well, that looks pretty good.
That excavator always did a good job tracking on material for some reason.
I can see how that shale breaks up into nice little gravel.
This spot was only muddied up because I just put this pipe in
and some dirt kind of came up when I did it. So.
Yeah, look how that rock breaks up.
All right, well, the Hitachi is working good
This is the second excavator I've ever bought.
I've had this over 12 years now.
It's all ready.
I'm about to bring this out on two jobs,
so I just wanted to fix some stuff on it first.
We're all done here. Let's go work on something else.
