Important: The instructions in 4.1.2. must be
observed when working with synthetic
operating medium F5.
CAUTION
Oiler 136 should always be filled to the half way
mark, maximum, (when the pump is cold); top
up as necessary. When the pump becomes
warm, the lubricant expands and can spill over
if the oiler is too full.
