ADJUSTING GAS SPRING FORCE STEP 1 AND 2
The method of releasing gas from a BV valve is similar to the TV valve. However in this case you will need to use a flat rod of diameter less than 2.0 such as a 1.8mm drill bit of a 1.5mm Allen key.
Upon receipt, fit the gas spring to the application, operate the springs and observe the movement.
Care should be taken on this first compression. The supplied force in the gas springs might be so great that damage could occur to the part to which the gas springs are attached. For example, if the springs are attached to a sheet metal lid closing for the vertical to the horizontal, the force required to operate the springs could cause the lid to bend before the gas springs compress.
Safely support the load and remove the gas springs. Unscrew the end fitting from the body end (the bigger section). The hole which leads to the internal ball valve can now be seen T-Valve.
If this is a locking gas spring, please ensure it is fully extended before operating the valve
