346 xp heated handles

[carlos]

iam sure these used to run hotter on my saw, what should i check? to be honest i dont even know how they work, is there a way to test them off the saw?

any thoughts welcome.

thanks carl

It is all very simple, there is a coil pack mounted behind the flywheel. the flywheel has a ring magnet embedded on to the back of it. Once the flywheel spins, the magnet spins round the coil and produces a bit of a voltage. You have two resistive heaters mounted in series with a switch between the voltage, the heaters and earth. Once the switch is thrown, you get toasty hands.

 

It is possible the switch has got a bit of shyte in it increasing its normal nominal resistance, it is possible one of the heaters has got a high resistance but I am not sure if there is a spec for them or if you just have to compare to a good set. Probably best to check the switch, check the connectors and see where that leads to.

Hi i had this issue with both my XPGs, first one had shyte in the switch as Spud suggested, but it also had a cut in the wire where it comes from the coil pack, under the carb and out to the handle. the other had been given a real hard life and the coil behind the rotor was coated in thick crusty sticky film, i think a mix of sap, oil, grease, crud and fine saw dust, it was also so thick it had reduced the vent hole size on the starter cover, a real mess. both saws were purchased in this non functioning heated handle state 2nd hand and were cheaper as a result. personally i would never let my saw get in that state. after much cleaning and some TLC both are working perfect. the trusty 346xpg

could well be crud related as i run veg oil on the bar and dont own an air compressor!

Bit of a sidetrack but is worth changing my 7 tooth sprocket to an 8 tooth on my 346?

If the bar is 13" or under then yes, If it is more then no unless the saw is ported etc!

 

Also depends on the size of wood typically cut and the type of cutting done!
