Version 1.2

–  It is best to apply grease in several jack positions, to ensure 

good distribution of grease. 

–  S version: Apply only small quantities of grease at each jack 

position, so that grease is not forced through the seals into the 
gearbox. 

–  R version: If no grease nipple is fitted, apply the grease directly 

to the spindle. 

 

NOTE 

Simple greasing during operation. 

The automatic grease dispenser 

Z-LUB

 provides optimum distribution 

of the grease. 

  Use the automatic grease dispenser 

Z-LUB

 instead of a grease 

gun. 

  ZIMM will be pleased to give advice. 

There are different greases for different applications. 

• 

High temperature 

• 

Low temperature 

• 

Food processing industry 

• 

Heavy-duty applications 

• 

etc. 

  ZIMM will be pleased to give advice.
