Place the tire changer on a firm, smooth and unbroken floor. Drill four holes in the floor corresponding to the holes pre-drilled in the base of the machine. Holes should be 80mm deep. Its diameter is 10mm.

- Page 9 (8) Mounting 1. Before any mounting, inspect tire for damage and verify size match between tire and wheel (fig. 14). This information must be read and followed carefully to prevent accidents and injuries during mounting. Attempts to force a bead seat on mismatched tires and wheels can cause the tire to violently explode, causing serious personal injury or death to operator and/or bystanders.

- Page 11 T. If tire and wheel are properly lubricated and operator cannot achieve bead seal after three or four attempts, the valve core may be removed from the valve stem to allow more air flow into the tire to assist with bead seal. After bead seal is achieved, remove the clip-on chuck and rein- Use of bead sealing jets without a tire in place can cause stall the valve core.
- Page 12 (11) Stages of Inflation on a Conventional Tire and Rim Review these descriptions and diagrams carefully. Refer to them as necessary during bead sealing, bead seating, and inflation to verify that you are proceeding properly and safely. Bead Sealing Bead sealing is the process of capturing air pressure between the tire and the rim. The tire will usually contain about 1/2 to 2 PSI at initial bead seal.
