NOTE: 

•

Direct mounting should be used for lubrica-
tion points that are easily accessible. 

•

Remote mounting is recommended if you 
answer YES to any of the questions below.

1. Is the ambient temperature at the lubrica-

tion point higher than +40°C (104°F)?

2. Is it necessary to remove protective 

screens, walls or other types of protection 
in order to reach the lubrication point?

3. Is the lubrication point exposed to high 

vibrations?

4. Is it difficult to access the lubrication point 

during operation of the machine?

5. Is the lubrication point exposed to any of 

the following:

•

water jets for high-pressure cleaning 
machines?

•

corrosive chemicals?

•

high temperatures?

•

falling materials?

The lubricator has a self-protection mecha-
nism which shuts off the drive unit at counter 
pressures higher than 5 bar (72.5 psi). Most 
bearings require 0.5 - 2 bar (7.2 to 29 psi) 
pressure (without tubes, extensions, angles, 
etc.). 

Use the following procedure to check the coun-
ter pressure of the application prior to installa-
tion.

NOTE: 

•

Be sure to use a lubricant cartridge that 
contains the same grease used in the 
application.

•

The best measurement results are 
achieved during operation.

1. Clean the lubrication point to remove any 

potential contaminants.

2. Prime the grease line and all accessories 

with the same grease that is contained in 
the lubricator (See Parts, page 16 for a 
complete list of available grease car-
tridges).

3. Remove the plug (A).

4. Install lubricator unit 

into adapter (B).

5. Install reducers, 

extensions, grease 
line, etc. (if neces-
sary).

6. Screw a pressure 

manometer into the 
lubrication point (dd) 
(F
