PK-110 Manual

Thank you for purchasing the American Weigh

PK-110 multi-use hanging scale. Please read all operating

instructions carefully before use. Scales are precision

measuring devices and should always be handled with

proper care. To ensure years of reliable service, keep these

simple tips in mind:

• Do not exceed the scale’s maximum capacity.

• Store your scale in a clean, dry location. Dust, dirt,

and moisture can accumulate on the weighing

sensors and electronics causing inaccuracy or

malfunction.

• Avoid using your scale in close proximity to strong

radio wave emitting devices such as cordless phones.

• When weighing heavy items, use proper lifting

technique to avoid back injury.

• Do not drop items onto the weighing hook. This may

cause damage to the load sensor.

• Avoid dropping your scale. The warranty does not

cover damage due to rough treatment or overload.

• Checkthebatteriesrstifyouarehavinganytrouble

with your scale. This simple step can remedy most

scale issues.

• Calibration should be checked and adjusted

occasionally as part of routine scale maintenance.
