Installation, care and maintenance 

Minette

WARNING!

If the seal leaks, the oil casing 
may be under pressure. Hold 
a rag over the oil casing screw 
in order to prevent splatter. 
See “Safety precautions” for 
additional information.

Explanation of symbols

= Oil screw

= Inspection plug

It is easier to drain the oil if the other oil screw 

is also removed.

Fill up with new oil.

A paraffin oil with viscosity close to ISO VG32 is 

recommended. The pump is delivered from fac-

tory with this type of oil.

In applications where poisonous properties are 

of less concern, a mineral oil with viscosity up to 

ISO VG32 can be used.

Always replace the O-rings on the oil screws. Put 

the screws back and tighten them.

Changing the oil

Lift the pump horizontally on relief table.

Turn the pump so that one of the oil screws 

faces downwards. Lock the pump with a support 

preventing it from rolling over.

Unscrew the oil screw.
