1. (1) A qualified person must determine if it is safe to pull a tree.
2. (2) Positive communications must be maintained at all times between the tree-pulling machine operator and the person falling the tree. Citizens' band radios are not considered positive communications.
3. (3) An audible signal must be sounded when the initial pull is made on the tree and the line is tightened.
4. (4) A choker, choker bell or a line with a sleeve shackle must be used as the means of attachment around the tree when tree-pulling. The bight on the line must be only that necessary to hold the choker or line around the tree.
5. (5) The tree-pulling machine must be equipped with a torque converter, fluid coupler or an equivalent device to ensure a steady, even pull on the line attached around the tree.
6. (6) The tree-pulling line must have as straight and direct a path from the machine to the tree as possible. Physical obstructions which prevent a steady, even pull on the tree-pulling line must be removed or the line must be rerouted.
7. (7) The use of a siwash, in lieu of using a block and strap for the purpose of changing the tree-pulling lead, is prohibited.
8. (8) In tree pulling operations, the back cut may be below and on a horizontal plane with the face cut.
