WRAPPING MODES

Auto Film This mode is automatically selected when the wrapper is turned on or when the STOP switch

is pressed. Narrow or Wide film is automatically selected depending on package size.

Narrow Film Wraps packages with Narrow film only.

Wide Film Wraps packages with Wide film only.

CONTROL SETTINGS

Film Tension Leave at 7 for snugly wrapped packages. To loosen the wrap, set at a lower number.

Packages with sharp bones or bulges will wrap better with a slightly looser wrap (lower

number).

Sealer Belt Set at 325° F. Allow to warm up 10-15 minutes. Adjust lower if holes develop on package

Thermostat bottom. Adjust higher if film doesn’t seal.

PACKAGE REQUIREMENTS

USE THE CORRECT TRAY SIZE

Caution:

1. Loose items could fall out of the tray and jam the machine.

2. Use deep trays for loose parts that might roll off.

3. Product must be stable and lay flat in the tray without bouncing around.

4. Lay sharp bones down on the bottom of the tray so the film doesn’t puncture.
