Loosen the four bolts by the slots on the boom. There is a grease fitting in a depression in the side of the boom. There should be a threaded cap over the fitting. Pump grease in it until the chain tension is correct and re-tighten the bolts. Do not over tighten the chain. With the boom level, you should be able to put three fingers between the chain and boom. If you get it too tight, it will cause excessive wear. If grease comes back out of the fitting when you take the grease gun off, you need to get a new fitting. It is a special fitting with a check valve in it.
