If you are just starting out with hands-on work, this is the most basic question; you can ask the experienced workers.
At 50 load, work is generally done on the shaft side; after the air valve is activated, a plastic rod at the top lifts it up. At 100 load, the external air valve operates
I really hadn’t noticed that. We use Holbig’s variable air volume control system, so there’s no need for a unloader
The load is controlled by the solenoid valve; checking the solenoid valve is one way to do that
It’s not possible to check this; it’s necessary to determine the length of the load relief valve stem before installation. The lubrication system for the stem’s movement should work properly, and the air bag of the load relief valve must not leak air. After installation, it can only be run for viewing.
