This is a great chainsaw. It has never had issues like some others. You will need to buy a scrench. Oregon has a 17-piece chainsaw tool kit you can get from Walmart or Amazon (recommended). There used to be a simple one at Northern Tool, maybe it will come back.=======================================================================================================================================================================================================================================================================================
Senix Model: CS4QL-L3, 46cc 16" Chainsaw. Senix chain. 57 DL | 3/8 LP .050 ga. Manual. New spare spark plug included. No case. Did not come with tool. I will let it go for $75.00. Plenty of power and less weight than most saws this size. ===========
If you need an 18" guide bar, I can sell you a used one if you are on a budget with chains. It works perfectly.================If you don't know, a 56DL chain and bar will work on this saw, as well.
