Do not modify this scale in any way. Unauthorized modification may impair the function and/or
safety and could affect the life of the product. There are specific applications for which the scale
was designed.
Use the right tool for the job. DO NOT attempt to force small equipment to do the work of larger

other reproductive harm.
⚠WARNING
WORK AREA SAFETY
Inspect the work area before each use. Keep work area clean, dry, free of clutter, and well-lit.
Cluttered, wet, or dark work areas can result in injury. Using the scale in confined work areas may
put you dangerously close to other cutting tools and rotating parts.
Keep children and bystanders away from the work area while operating the scale. Do not allow
children to handle the scale.
⚠WARNING
PERSONAL SAFETY
Stay alert, watch what you are doing, and use common sense when operating the scale. Do not
use the scale while you are tired or under the influence of drugs, alcohol, or medication. A moment
of inattention while operating the tool may result in serious personal injury.
Dress properly. Do not wear loose clothing, dangling objects, or jewelry. Keep your hair, clothing
and gloves away from moving parts. Loose clothes, jewelry, or long hair can be caught in moving
parts. Air vents on the tool often cover moving parts and should be avoided.
Wear the proper personal protective equipment when necessary. Use ANSI Z87.1 compliant safety
goggles (not safety glasses) with side shields, or when needed, a face shield. Use a dust mask in
dusty work conditions. Also use non-skid safety shoes, hardhat, gloves, dust collection systems,
and hearing protection when appropriate. This applies to all persons in the work area.
Do not overreach. Keep proper footing and balance at all times.
⚠CAUTION

they are designed. Plan your work, and use the correct product for the job.
Check for damaged parts before each use. Carefully check that the scale will operate properly and
perform its intended function. Replace damaged or worn parts immediately. Never operate the
scale with a damaged part.
Store the scale when it is not in use. Store it in a dry, secure place out of the reach of children.
Inspect the tool for good working condition prior to storage and before re-use.
Use only accessories that are recommended by the manufacturer for use with your scale.
Accessories that may be suitable for one product may create a risk of injury when used with

Page 6 of 11
another tool. Never use an accessory that has a lower operating speed or operating pressure than
the tool itself.
Grounding
⚠WARNING
This scale must be grounded while in use to protect the operator from electrical shock. This scale
is equipped with an electrical cord that has an equipment grounding conductor and a grounding
plug. The plug MUST be plugged into a matching receptacle that is properly installed and
grounded in accordance with ALL local codes and ordinances.
DO NOT MODIFY THE PROVIDED PLUG. If it will not fit the receptacle, have the proper
receptacle installed by a qualified electrician.
CHECK with a qualified electrician or service person if you do not completely understand the
grounding instructions, or if you are not sure the scale is properly grounded.

1) Make sure the scale platform is level.
2) Check if something is loaded on the sensor beneath the platform pan.
3) Remove the platform pan and adjust (6) the adjustable foot for the sensor under the upper
