WARNING
The seat may pop suddenly when force is applied. Stand with feet apart
when applying striking action. Keep head back so the tool does not
strike your jaw when the seat pops. Ask for a work partner to steady you
to avoid slipping. The bumper sliding upward against the stop nut
creates a pinch point that can cause hand injury if gripped improperly.
Always hold the bumper by the handles only and use leather work gloves
to lessen the shock to your hands.
