Safety Features
- Ram Lock Nut: Prevents lowering of the ram. The ram lock nut must be lowered as the aircraft is being lifted.
- Locknut Retention Ring: Prevents the lock nut from being unscrewed from the 2nd and 3rd stages.
- Hold-to-Run Air Valve: Requires the operator to hold the air valve lever to raise the ram using the air pump. Releasing the air valve lever stops the upward movement of the ram.
