Weight Adjustment - K-Systems AV1 Mode D'emploi

AV1 AND AV5 USER MANUAL

2.3 Weight Adjustment

The anti-vibration table AV1 and AV5 can be used to hold equipment with a weight from 15 to 72 kg. However,
the table needs to be installed correctly to have the optimal anti vibration ability.
NOTE: Before proceeding it is important that you know the exact weight (in Kg) of the equipment,
which you will place on the anti-vibration platform.
When AV1 or AV5 leaves the factory it is equipped with 3 springs and an extra weight plate. See right column in
the table below. The yellow areas indicate the optimal working conditions for the 3 different installation methods.
Example: The total weight of equipment placed on the anti-vibration platform with 3 springs should be in the
range from 45- 72 Kg.
The Anti-vibration table can be modified in 2 steps to gradually work optimal with less heavy equipment on
the platform.
Step 1: To work with equipment from 30-45 kg one spring is removed so only 2 springs are used.
NOTE: Only remove the middle spring, when needed.
Step 2: To work optimal with equipment from 15-30 kg 2 springs are installed and an extra weight plate must
be used.
