Husqvarna chain saw / cutoff  specifications by model
Including engine displacement, bore, stroke, power, weight, basic carburetor settings, and idle/max RPM specs.
Updated December 2014 by Lee Sluga, service manager for Bill's Saw Shop, Salamanca, NY, (716) 938-9846.

This is an unofficial list. I am human and have been known to make mistakes, so use it at your own risk.
However, I have made every attempt to get accurate and official results for all listed numbers, from reliable sources such as workshop manuals.

We do stock lots of parts, accessories, bars, chains, etc and ship daily.
At some point in the near future I hope to have a shopping cart system up, until then, just call or email us if you need anything, please!

Thank you for visiting!  If you have a suggestion, more info for the sheet, or any other questions, feel free to email us.

LEGEND:
C.C. = Engine displacement in cubic centimeters
C.I. = Engine displacement in cubic inches, I assume converted from cubic centimeters, since Husqvarna uses the metric system primarily.
Bore = Cylinder bore in millimeters.
Stroke = Stroke in millimeters.
H.P. = Manufacturer rated horsepower
KW = Manufacturer rated power, in kilowatts.
LBS. = Weight of powerhead only (no bar, chain, fuel or oil) in pounds. An asterisk (*) indicates weight INCLUDES typical bar and chain.
KG = Same as above, except in kilograms.
Initial H = Manufacturer recommended initial setting for high speed fuel mixture
Inital L = Manufacturer recommended initial setting for low speed fuel mixure
Idle Speed = Manufacturer recommended idle speed.
Max RPM = Manufacturer recommended maximum no-load top speed (other than typically mounted bar and chain) in crankshaft revolutions per minute.
Source = References where these number were published/found. (OM - Operator's Manual, WM - Workshop Manual)


FIXED = The carburetor has a fixed (non-adjustable) jet for this fuel circuit.
NL = Not Listed (I was unable to find official published numbers)
NA = Not Applicable (ie, the 500 series of chainsaw have microprocessor controlled fuel metering, therefore do not have adjustable fuel mixture needles)
