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 lubrication 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?
•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).
*Loctite
ration.
®
is a registered trademark of the Loctite Corpo-
4. Is it difficult to access the lubrication point
during operation of the machine?
5. Is the lubrication point exposed to mechanical forces such as falling materials?
Installation Guidelines
Do not puncture, open or take canister apart.
Opening or breaking the canister will expose
users to the fluid and gases contained inside.
•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 cartridges.
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.

Graco recommends checking the counter
pressure by connecting an EM-Drive Lubricator to a pressure manometer (user supplied).
A pressure manometer is a simple device that
measures pressure output. To build a pressure
manometer you need a pressure gage (aa),
tee fitting (bb) and stop valve (cc). FIG. 2
shows a correctly assembled pressure
manometer, connected to the lubricator and a
lubrication point.

Counter Pressure Test Procedure
1. Clean the lubrication point to remove any
potential contaminants.
2. Remove the plug (A).
3. Install lubricator unit
into adapter (B).
4. Install reducers, extensions, grease line,
etc. (if necessary).
5. Screw a pressure manometer into the lubrication point (dd) (FIG. 2, page 8).
6. Ensure the stop valve (cc) of the pressure
manometer is open.
7. Attach lubricator and adapter (B) to the
pressure manometer as shown in FIG. 2
and turn the switch to “ON” (ff).
8. Run manometer for about 20 seconds.
Observe gauge and repeat this procedure
until pressure registered on gauge stays
constant.
9. To determine counter pressure, wait
approximately 5 minutes until system has
relaxed. Do one
more discharge by turning
unit OFF; then ON again until it dispenses
for no more than 5 seconds.
10.Wait approximately 5 more minutes to
make sure system does not lose pressure
and remains constant.
11.Disconnect adapter (B) from manometer.
NOTICE
Do NOT disconnect lubricator from adapter
(B). Screwing anything into end of lubricator a
second time will damage self-sealing threads.

12.If counter pressure is 4 bar (58 psi) or
higher, flush lubrication point with a grease
gun.
After flushing, repeat counter pressure test.
If the counter pressure does not decrease
you may need a different lubricant or lubricator canister. Contact Graco Customer
service for assistance.
Grounding Clamp Installation
To reduce the risk of fire or explosion, equipment mounted in potentially explosive atmospheres must be correctly installed using a
grounding clamp. Part No. 124304 is available
from Graco Customer Service or your local
Graco distributor.
EC-120 Models Only
FIG. 3
1. Insert lubrication canister inside grounding
clamp (1) making sure bottom of canister is
flush mounted to the grounding clamp as
shown in FIG. 3.
2. Attach a grounding cable (2) between the
grounding bracket (1) and an earth contact
(3) as shown in FIG. 3.

Priming / Prefilling Fittings and
Grease Lines
All grease lines (extensions and tubes) must
be primed/prefilled. Without priming/prefilling,
the lubricator would first need time to fill the
tubes with lubricant before it would actually
supply lubricant to the lubrication point.
Example: A tube that is 1/2 meter long x 6 mm
(19.5 inches x 1/4 inch) diameter, requires
about 14 ccm (1 Tablespoon) of lubricant. With
a 12 month activator screw, the lubricator
would need about 1-1/2 months to fill this tube.
F
IG. 4 illustrates one way to pre fill using stan-
dard parts for a grease gun with extension
thread M10 x 1.
2. Prime the grease line and all accessories
with the same grease that is contained in
the lubricator.
3. Secure grease lines with ties or similar
means.
Direct Mounting
Reducer or oil throttle (optional)
FIG. 4
Remote Mounting Installations
•Installations up to 3 ft away from the lubri-
cation point can be mounted with flexible
tubes and a bracket. Refer to F
and F
IG. 7 for examples of correct remote
mounting installations
•Remote installations require a grease line.
Graco recommends using a tube with an
inside diameter of at least 6 mm (1/4 inch).
1. Select a position for the lubricator that is
easy to access and protected from
high-pressure water jets, falling materials,
corrosive chemicals and extreme temperatures. Temperature must be below +40°C
(+104°F).

Activate the lubricator prior to installation.
For the following instructions, unless otherwise
instructed, refer to FIG. 8.
1. Verify the activator screw contains the gas
generating pellet.
2. Hold the lubricator with the plug end facing
down.
3. Screw the correct activator for your application into the bottom of the lubricator and
hand tighten (F
IG. 9). (See page 13 for acti-
vator options and/or Parts, page 18).
FIG. 10
Do not puncture, open or take canister apart.
Opening or breaking the canister will expose
users to the fluid and gases stored inside.
•Once installed, do not remove the activator
from the lubricator at any time.
•After a lubricator is activated, the discharge
period cannot be changed.
5. Shake the lubricator and listen for the pellet
rattle inside the canister to insure that the
gas generating pellet (C) (F
IG. 8) has fallen
from the activator into the bladder. This
starts the chemical dispensing reaction that
builds up pressure (up to 4 bar / 58 psi) and
causes the piston to move forward.
6. Write the installation and replacement
dates on the lubricator.
NOTE: Once a lubricator is activated, the discharge period cannot be changed. Do not
remove the activator from the lubricator at any
time.
