Hitachi CS40EK = Tanaka ECV3800
« on: June 13, 2014, 03:53:31 pm »
I been thinking about buying a new "small" saw for some time. I have a Dolmar 420, a Oleo Mac GS350 and a Stihl 180. I don't really need it but I recently left my 180 at my grandparents place after selling the Mc Culloch 740. So replacement was in order.

What is the user profil?

My grandparents place has about an acre around the house and a few acres forest. So I would only need a small saw for light work. The larger saws I have at my place and would take there as needed. I like the saws in the 40cc range because they have a good weight and power profil for light work but can also stand up to medium work if required.

So a few weeks ago I happen to come by an add on the net for a little saw of older design. Since there is hardly any quality info on the net about it, I just trust my gut feeling and go on and buy it.

The data:
38,2 ccm |1,76 kW/ 2,4 HP / magnesium split body / hard chrome cylinder / max. rpm 14500!!! / 4kg = 8.82 pounds / made in Japan

So this little box arrives


User manual, tools and the "bumper spike" as the manual call's it!  ;D  Self assembly is the way to go.


When you take it out of the plastic bag this comes out.


Klassik arrangement, on off switch, choke and between the two under the grip is the air intake.


Looking from the clutch side. Classic rubber antivib and front chain tensioner.

A look at the chain brake set up. Looks a little primitive but still well made.


Take off the hood and voilá the air filter.


Primitive air filter by todays standards.


Carb access with classic limiter screws and a funny looking idle screw. A small coin can fit into the slit.


No idea what the numbers mean but 97 and 2002 are included, so it's obvious that it is an older design.

If you take off the top plastic part the magnesium body is exposed and everything is easily accessed. The decomp button to the left of the cylinder and the ingnition cable are in some type of "fiberglass" heat protection sleeve.


Taking off the starter and looking at the flywheel.


Exhaust is only an empty can with the insulation / gasket still stuck to it.


Classic two ring piston


A short video. First filling. First half carb set to 13100rpm, second half carb set to 14100rpm. Wood, some type of spruce/pine/fir, was a gift ;) from a construction site and slightly coated with cement.

Oh yeah the price was 219€ = 297$! Here about half price from original for a brand new pro saw not bad.

Hitachi and Tanaka are now one company. Same as Husqvarna & Jonsered, Echo & Shindaiwa, Dolmar & Makita, etc... So yes Hitachi still has obviously old stock of Tanaka design that they are selling at bargin prices sometimes.

Forgot to add (both fully fueled, without bar and chain ):
Dolmar 420(old type with 2.7hp)         5.5kg = 12.13 pounds
Hitachi CS40EK                                    4.6kg = 10.14 pounds

The weight is right for sure.  So does it cut like a 38cc-40cc saw stock?
