Chain Routing & Adjustment; Engine Removal - Husqvarna SC18 Workshop Manual

CHAIN ROUTING
The chain can be replaced by disconnecting the master link on the old chain and hooking
up the new chain to the old one. Pull the free end of the old chain until the new chain is
pulled through.
Re-connect the chain with the new master link.
To replace a broken chain the skid pan will have to be removed and the unit turned
upside down. Refer to the routing guide below for assistance.
