Wood Chipper Assembly Manual Circle G Tractor Sales, Inc. Before you begin, you will need a set of metric sockets or wrenches, allen wrenches, and a way to lift the chipper body (appr. 800 lbs). Step 1: Assemble the base or box for chipper to sit on. Step 2. Lower chipper body onto the stand and bolt in place. Be sure half moon cut out on stand is on same side as PTO shaft and pulley. Make sure the infeed drum is centered in the infeed shute, if it is not remove the two yellow covers over the infeed shaft and drum, there are two set screws in each bearing on each end of infeed drum, loosen and move drum to center of shute. You may have to remove the short infeed driveshaft with spring around it in order to line properly, then replace. Check the clearance between the bed blade (blade located under the infeed drum with 3 allen wrench head screws) and the blade on flywheel, it should be between 0.10 to 0.30 clearance between bed blade and chipper blade.
