Instructions EM Drive Lubricators 3A0415D ENG Provides a continuous, precise and temperature independent supply of grease or oil lubrication to all lubrication points of sliding- and roller bearings, drive- and transport chains, sliding guideways, open gears and seals. For professional use only. Not approved for use in European explosive atmospheres. 75 psi (0.5 MPa, 5 bar) Maximum Working Pressure Important Safety Instructions Read all warnings and instructions in this manual. Save these instructions.
Warnings The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclamation point symbol alerts you to a general warning and the hazard symbols refer to procedure-specific risks. When these symbols appear in the body of this manual, refer back to these Warnings. Product-specific hazard symbols and warnings not covered in this section may appear throughout the body of this manual where applicable.
WARNING WARNING EQUIPMENT MISUSE HAZARD Misuse can cause death or serious injury. • • • • • • • • • • • • Do not operate the unit when fatigued or under the influence of drugs or alcohol. Do not exceed the maximum working pressure or temperature rating of the lowest rated system component. See Technical Data in all equipment manuals. Use fluids and solvents that are compatible with equipment wetted parts. See Technical Data in all equipment manuals. Read fluid and solvent manufacturer’s warnings.
Component Identification Pressure Relief Procedure A B C 1. Cover lubrication point (A) and lubricator (B) with a heavy rag to absorb any fluid that may leak out while loosening the adapter. 2. Carefully unscrew support adapter (D) from the lubrication point (A).

Installation and Setup Installation and Setup Determining Correct Mounting Method NOTE: • Direct mounting should be used for lubrication 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.
Installation and Setup 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. 1 shows a correctly assembled pressure manometer, connected to the lubricator and a lubrication point. dd cc bb aa ff ee FIG. 1 aa bb cc dd ee ff Pressure Gauge Tee Fitting Stop Valve Lube Point Lubricator ON / OFF Switch 7. Ensure the stop valve (cc) of the pressure manometer is open. 8.
Installation and Setup Circuit Board Settings Function Display Red and green LED’s (Light Emitting Diodes) are on the circuit board and visible through the transparent cover.
Installation and Setup Setting the Lubrication Canister Volume Dip Switch Position Options: Volume 3. Use a small screwdriver or your finger to move dip switches to the desired position. Refer to FIG. 5. There are 3 switch position options. These positions correspond to each of the 3 lubrication canister sizes: 60 cc, 120 cc, 250 cc. Refer to FIG. 5 for correct position for each option. • • Dip switches 3+4 marked “VOL” are used to set the lubrication canister size.
Installation and Setup Changing the Dip Switch Setting • The discharge period (Time) and/or lubrication canister size (Volume) can only be changed when a new lubrication canister is attached. If settings must be changed during current operation; i.e., after discharge was started, you must attach a new, completely filled lubrication canister and a new battery pack. For horizontal mounting a bracket clip must be used to hold the lubricator in place.
Installation and Setup Remote Mounting Installations Grease Lubrication with Tube Refer to FIG. 7 and FIG. 8 for examples of correct remote mounting installations. A • Remote installations require a grease line. Graco recommends using a 5/16 inch flexible hose. • 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.

Operation Installing Lubricator to Lubrication Point 9. Install lubricator unit into adapter (B) (if it is not already installed). 1. Clean the lubrication point to remove any potential contaminants. 2. Verify the thread of the lubricator corresponds to the thread of the screw point. 3. Verify Dip Switches are correctly set. See Table 1, page 8. 4.
Maintenance The “TIME” switches 1 and 2 of the 4-way code switch in the drive unit match the desired discharge period. • All components are properly assembled and screwed together hand tight. • Removing Lubrication Canister 1. Switch the rotary switch position from ON to OFF. To begin the discharge: Turn the rotary switch from the OFF position to the ON position. Maintenance 2. To disconnect adapter from lubrication point, follow pressure relief procedure provided on page 4. 3.
Maintenance Installing the New Lubrication Canister Sparking can occur when changing the battery pack. Only replace the battery pack in a non-hazardous location, away from flammable fluids or fumes. 1. Install new battery pack in drive unit in the direction of the arrows as shown in FIG. 10. NOTE: Only replace the battery pack with a Graco battery pack for EM Drive Lubricators, part number 124261. Handle and dispose of the battery pack properly. 7. Remove the plug (A). A 8.
Troubleshooting Lubrication Canister Disposal Dispose of hazardous fluid in approved containers, and according to applicable guidelines. Read the MSDS to know the specific hazards of the fluids you are using. Storage When lubricators are not immediately installed, they must be stored for a maximum of 1 year in a dry, dust free, sunlight protected room, indoors. The room temperature cannot exceed 70°F (21°C).
