General Safety Instructions:
Do not puncture or scratch lining
of fuel cell. If lining is broken, fuel
penetrates and activates self-sealing
layers. Activated layers swell and trap
fuel. Activated green spongy material
also contaminates fuel system. This
makes it necessary to replace fuel cell
and flush fuel system.
