WEIGHTS HANDLING Safety Precautions

Please be very careful after receive the parcel of weights to open its packing

Store in cupboard for protect from dust and atmospheric pollution by glass covers

When not in use weights should be also store under cover to keep them as free from

contamination as possible

Weights should be used in extremely stable environment

Proper handling method must be used to ensure that the weight is not damaged in use

If well handled under ideal conditions weights no need to clean.

Weight of less than 10mg nominal mass should not be cleaned.

If necessary clean according the class and its proper process

After cleaning all weights should be allowed to stabilize.

Never touch the weights with ware hand, Always use with gloves, lifter,

tweezers to handle the weights

Never put weight on any surface

Heavy Weights 10kg & 20kg should be handle with suitable lifters

After use keep Weights in the Original Packing Box

One set of weights should not be mix with other sets

Jingles or falling down is strictly forbidden, in avoid of any scratch or jingle

No touch any erosive matters

When you send weights for calibration / re-calibration weights set must be covered packed

in large container or cartons to protect weights and weight case

Always weights should be kept properly and carefully
