General Safety Instructions:
All regulations and instructions
for handling fuel shall be strictly
observed.
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.
