Cleaning the Stainless Steel Shot

Stainless steel shot should be kept as clean as possible at all times. We recommend that shot be cleaned after every second or third use.
1. steel shot cleaner according to the directions on the bottle.
2. Add the steel shot into the tumbler.
3. Add enough diluted shot cleaner to cover about 1” over the steel shot.
4. If the water appears dirty after tumbling, rinse the shot and repeat the process (the shot is clean when the liquid cleaner is the same color it was before it was put in the tumbler).

Care and Maintenance of Tumbler

1. Before operating the tumbler, be sure that the bearings are cradled in the end plates of the tumbler.
2. Be sure both shafts turn freely; a binding shaft may throw the barrel off its rollers.
3. Oil the bearings at the beginning of the operation and once a month after the initial oiling; use oil sparingly.
4. Do not spill abrasives on bearings or motor.
5. Use care, this motor will become hot to the touch when running. This is normal but requires caution around the motor.
6. Tumblers are protected by a thermal overload device; if the motor overheats, the unit automatically shuts off.
If this happens, check for bound bearings or excessive weight; wait for the motor to cool, and it will restart by itself.
7. To assure long belt life, make certain that motor and drive pulleys are in line. Necessary adjustments can be made by
adjusting the set-screw on the motor pulley.
8. If the barrel or the roller guides become wet, dry them thoroughly to prevent barrel slippage.
