Installation and Setup
Determining Correct Mounting
Method
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 mechan-
ical forces such as falling materials?
Installation Guidelines
• Before installing the lubricator, the lubrica-
tion points and any extensions must be
adequately pre-lubricated with the same
lubricant contained in the lubricator. A 400
gram lubricant cartridge for grease guns is
available from Graco. See Parts, page 18
for a complete list of available lubricant car-
tridges.
• Install one lubricator per lubrication point.
• When oil is used for lubrication, a
non-return valve (oil throttle) must be
installed. This will prevent oil leakage from
the lubricator. An oil throttle is available
from Graco. See Parts, page 18.
• The grease nozzle of the lubricator has an
R 1/4 male thread. If your application has a
different thread you may need to use a
reducer.
• Do not overtighten the plastic thread of the
lubricator.
• For all metal to metal connections (i.e.,
extensions, reducers, etc.) make sure to
use LOCTITE
®
243* or equivalent
(semi-tight screw locking).

Preparing for Installation
Most bearings require a pressure of 0.5 to 2
bar (7.2 to 29 psi) pressure (without tubes,
extensions, angles, etc.). Use the following
procedure to check the counter pressure of the
application prior to installation.
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.
Checking the Counter Pressure
NOTE: A 60 cc EM-Drive Lubricator containing
the same lubricant you are dispensing is
required to perform the Counter Pressure test
correctly. Contact Graco Customer Service or
your local Graco distributor to order this part.
Do not puncture, open or take canister apart.
Opening or breaking the canister will expose
users to the fluid and gases contained inside.
