346xp - stock bar and chain?

[Martyn Amos]

If it's the same post that I remember the candidate was told he could not use his 357xp because his trousers were class 1 and only rated for a chain speed of 20 m/s.

 

Husqvarna quote 21.4 m/s at 9600 rpm(max power) as the chainspeed for a 357 with a 7 tooth 3/8" sprocket.With a 7 tooth 0.325" sprocket the chain speed would be 18.5 m/s and an 8 tooth 0.325" sprocket the speed would be 21.2 m/s.

 

So it would appear that a 7 tooth 0.325" sprocket should be used with class 1 trousers.(Just don't tell the instructor that at max speed (13500 rpm) the chain will be doing 26 m/s)

 

seems like it depends on the trainer? i did cs30/31 with class one front protection only and used a 357xp,also did cs38/39 with same trousers
