Preparation

Before every use, follow these procedures to set up your slip roll for safe, accurate, and efficient use.

To prepare the slip roll for use:

1. Turn the thickness adjust knob to lower the lower roller to approximately 1/4" below the upper roller. Use calipers or a spacer to set the distance between the rollers evenly at each end (Figure 12).

Flat Rolling

The Model G5771 can be used to flat roll sheet metal up to 16 gauge. This can be done to straighten, flatten, and slightly reduce the thick- ness of workpieces.

The main rollers of this machine present a pinch- ing hazard. Make sure no body part or clothing is near the area between the rollers. Failure to follow this warning may result in fin- gers, hair, or clothing being pulled into the machine, causing personal injury.

To flat roll a workpiece:

1.Place the workpiece between the upper and lower rollers, as shown in Figure 14. Turn the thickness adjust knobs to lift the lower roller until the workpiece is held snug between the upper and lower rollers. Be sure to turn the thickness adjust knobs equal amounts.
