CS 3000, CS 303 T, CS 320 T

Here the Tophandle saws with 30.1 and 33,4cm³ displacement, which are the same with many components with one another.

CS 3000: L: 1 5/16 -> H: 1 3/8

The CS 303 and CS 320 T T should already comply with the new emission standards.

The CS 320 T has a Shindaiwa Pedant: 320 TS.

There is also an older CS 301 with 30,6cm³ displacement and without brakes! The following here should all have a brake.

CS 3500, CS 3501, CS 352, CS 353

Since this is relatively rare given so:

In the US the BDA CS 352 is:

Idle speed: 2500 to 3500R / min

Stall speed: 3900 to 4500R / min

Maximum speed: 11500 to 13000r / min


The difference between the CS 352 and CS 353 will be only the better exhaust cleaning means 352 catalyst, for those states that since pretend higher hurdles.

The CS 360 was advertised with 36,3cm³?

The CS 360 was offered in 2015 with a bit more power than CS 361st

CS 3600, CS 3700, CS 3900, CS 396, CS 4200

The 3600 and 3900 are the same in many components. This also applies to the successors CS 3700 and CS 4200th

The older saws have in the BDA no information about the idle and maximum speed:
Default: L + H => 1 to 1 1/4
If the carburetor is then set correctly, you can hear a slight four clocks at the idle maximum speed.

From my own screwdriver practice: Some CS 3900 will not run properly with interference-suppressed spark plugs. Particularly striking were with special fuel. Unsuppressed candle ran faultlessly in the saw.

Many components of the saws are equal. The piston and cylinder were there with 2 bore diameters.

Performance of the CS 5100 from Finnish BDA ISO 7293rd Similarly, many competitors are likely to measure the performance of their saws. Echo measures usually when ever making a power rating different. The "usual" echo value is below the ISO 7293!

CS 490, CS 500 ES, CS 500P, CS 501 SX

The CS 500 ES 2012 got a little more displacement due to the new emission standard than the "normal" CS 500th

The CS 490 was offered in 2015 to the US market for the semi-professional.

The CS 500P is available in the US since, 2015. The data for the speeds are from the Manual.

2015 brought echo with the CS 501 SX a saw with very good power to weight ratio in the "50cc class" that complies with the emission stage ST2. Shortly was the Echo CS 501 SX also available as Shindaiwa 501 SX in D.

There are at least 3 Echo saws labeled CS 550, which differ:

CS 590, CS 600, CS 610, CS 620P

Shindaiwa sister models: 598 and 600sx

The 590 Timberwolf should be a semi-professional version of this series. But According to the US side, the same engine power as the CS 600 is about 1/5 cheaper.

The CS 620P is also available as CS 620PW with wrap handle. The CS 620 has 13% more power than the CS 600th

CS 670, CS 6700, CS 680, CS 6800

These models are available already relatively long. At times, even simultaneously in different sales regions. Again and again these very similar saws have been enhanced in detail.

Two color versions of the CS 670 and CS 6700 are known. Once the orange-red, and then in the 90's a gray variant. Also a rescue variant was offered in the US. The capacity varies on the decimal place?

The CS 680 and CS 6800 are the successors of the CS 670 and CS 6700th

These saws with 80,7cm³ displacement have their roots developed more often in the 1980s and have been, but should be equal to each other in many components.


Carburetor adjustment for carburettor Walbro HDA ​​153B without Limiter:
CS 8001: L: 2 3/8 -> H: 3 3/8 Limiter to allow an adjustment from 2200 to 2800 1 / min and H 11500-12500 1 / min at L.


The ignition module of the CS 8001 is at:

1200 1 / min 10 ° BTDC, at

3000 1 / min 14,5 ° BTDC and

10000 1 / min 25 ° provide a spark BTDC.

This saw there were in the United States in the version QV 8000 as rescue saw.

From 2015 CS 800P was on the US market in the offer.
