Poly Liner Care; Welding On The Machine - Farm Aid 680 Owner's Manual

POLY LINER CARE:

The poly liner will grow and shrink dependant on temperature. Excessive heat combined
with sunlight can cause the liner to warp or bulge. All engineered polymers are
adversely affected by harmful ultraviolet light decreasing the life of the liner. Park inside
or in a shaded area to increase the life of your poly liner.
The liner will outlast the bolts that hold it in place. The feed is abrasive and wears the
head. Inspect the large headed fasteners that hold the poly liner in. If they are not round
or larger than the size of a quarter they are worn and need replacing. If the bolts fail it
will lead to premature failure of the liner. The bolts will last about 1/3 to 1/5 the life of the
liner and are easier and much less expensive to replace.

WELDING ON THE MACHINE:

➢ When welding on your mixer/feeder, do not allow the current to flow through the
ball bearings or the roller chains. Ground directly to the item being welded.
➢ Always disconnect the scale from the weigh bars. Be sure the current does not
pass through weigh bars or load cells or scale indicator.
➢ Disconnect the power wire from the scale.
