That would depend on where in the world you lived. But if you contact Husqvarna headquarters in Stockholm, Sweden, they will tell you where YOUR local spares outlet is to be found.
you have to see what size the bar is.
I have a 235e also but still don't know how totighten chain.
Not satisfactorily. The 021 is a lightweight saw.
you will need a ratchet, extension, 1/2 inch socket & a flat head screwdriver. Loosen the bar tension screw until the chain is loose. Then remove the two nuts & remove the bar, slip the chain from around the gear
A timber bear is 55cc. http://store.chainsawr.com/
The longest recommended was 31 inches. http://store.chainsawr.com/
Lossen the two bolts on the side of the chain bar, then use a straight screwdriver and straight under the chain turn the screw clockwise, don't tighten it to much, make sure it still turns, then tighten the bar bolts
Some Stihl chain saws have an adjuster underneeth the saw to turn up the oiler .
The 034 takes either a .325" or 3/8" pitch chain. My guess would be 3/8 .050 go to chainsdirect on eBay chose the chain for youre bar size.
A chain break is exactly what it sounds like, your chain becomes pinched in the wood or overheated due to lack of bar oil and breaks at usually one of the rivets. Easily fixed by your local saw shop. A chain brake on a chainsaw is a safety feature. The plastic or metal paddle shaped device in front of your upper hand is the lever to engage the brake. It is designed to stop the spinning chain instantly by tightening a band around the flywheel. In the event the tip of the chainsaw bar contacts something hard and throws the spinning chain upwards, your hand, wrist or arm should contact this paddle and engage the brake before he chain is able to strike your upper body and cause injury.
Not so sure it is. The manual shows none. If it suffers from reduced flow, the oil pickup may need to be checked for clogging. See link to manual, now a part of Husqvarna.
depends which length bar you want. try googling it. DYOR
