Lifting & Moving

This machine and its parts are heavy! Serious personal injury may occur if safe moving methods are not used. To reduce the risk of a lifting or dropping injury, ask others for help, and use power equipment and guide rods.

Do not attempt to lift or move this lathe without using the proper lifting equipment (such as forklift or crane) or the necessary assistance from other people. Each piece of lifting equipment must be rated for at least 25% more than the shipping weight of your lathe to support dynamic loads that may be applied while lifting. Refer to Things You'll Need on Page 16 for details.

To lift and move the lathe:

1.Remove the shipping crate top and sides, then remove the small components from the shipping pallet.

2.Move the lathe to its prepared location while it is still attached to the shipping pallet.

3.Unbolt the lathe from the shipping pallet

4.To balance the load for lifting, move the tailstock and carriage to the extreme right end of the bedway, then lock them in place.

Note: Before attempting to move the carriage, make sure the carriage lock is loose, the half nut is disengaged, and the power feed is disengaged (feed selection lever).

5.Position hardwood blocks under each end of the bed as shown in Figure 13. This will keep the lifting straps away from the leadscrew, feed rod, and spindle rod to prevent bending them during lifting.

Note: Fasten a center support between the hardwood blocks so that they will stay spread apart and in place when lifting (see the example in Figure 14).
