Timing belt worn; was slipping and making blade raising and lowering difficult
Repair generally went well. However, I needed to remove bottom pulley and set screws were very difficult to get at and they were also very small in size, allowing little force to be placed on allen wrench to remove the 2 set screws.
I have instructions that came with the saw, however it still takes about 45 minutes. Not too difficult, but time consuming. To complete the repair after putting the belt on, it needs to be adjusted to the right amount of tension. It works good!
