FIRE AND EXPLOSION HAZARD

When flammable fluids are present in the work area, such as gasoline and windshield wiper fluid, be aware that flammable fumes can ignite or explode. To help prevent fire and explosion:

• Use equipment only in well ventilated area.

• Eliminate all ignition sources, such as cigarettes and portable electric lamps.

• Keep work area free of debris, including rags and spilled or open containers of sol-

vent and gasoline.

• Do not plug or unplug power cords or turn lights on or off when flammable fumes are

present.

• Ground all equipment in the work area.

• Use only grounded hoses.

• If there is static sparking or you feel a shock, stop operation immediately. Do not

use equipment until you identify and correct the problem.

• Keep a working fire extinguisher in the work area.

TOXIC FLUID OR FUMES HAZARD

Toxic fluids or fumes can cause serious injury or death if splashed in the eyes or on skin, inhaled, or swallowed.

• Read MSDSs to know the specific hazards of the fluids you are using.

• Store hazardous fluid in approved containers, and dispose of it according to applica-

ble guidelines.

PRESSURIZED EQUIPMENT HAZARD

Fluid from the equipment, leaks, or ruptured components can splash in the eyes or on skin and cause serious injury.

• Follow the Pressure Relief Procedure before cleaning, checking, or servicing

equipment.

• Tighten all fluid connections before operating the equipment.

• Check hoses, tubes, and couplings daily. Replace worn or damaged parts

immediately.

WARNING

WARNINGWARNINGWARNING

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. For complete information about your material, request MSDS from distributor or retailer.

• Turn off all equipment and follow the Pressure Relief Procedure when equipment is

not in use.

• Check equipment daily. Repair or replace worn or damaged parts immediately with

genuine manufacturer’s replacement parts only.

• Do not alter or modify equipment.

• Do not puncture, open or take lubricator apart.

• Use equipment only for its intended purpose. Call your distributor for information.

• Route hoses and cables away from traffic areas, sharp edges, moving parts, and hot

surfaces.

• Do not kink or over bend hoses or use hoses to pull equipment.

• Keep children and animals away from work area.

• Comply with all applicable safety regulations.

PERSONAL PROTECTIVE EQUIPMENT

You must wear appropriate protective equipment when operating, servicing, or when in the operating area of the equipment to help protect you from serious injury, including eye injury, hearing loss, inhalation of toxic fumes, and burns. This equipment includes but is not limited to:

• Protective eyewear, and hearing protection.

• Respirators, protective clothing, and gloves as recommended by the fluid and sol-

vent manufacturer.

Component Identification

Pressure Relief Procedure

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

Determining Correct Mounting Method

Installation and Setup

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?

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:

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

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 cartridges).

3. Remove the plug (A).

• water jets for high-pressure cleaning

machines?

• corrosive chemicals?

• high temperatures?

• falling materials?

Preparing Lubricator for Installation

The lubricator has a self-protection mechanism 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 counter pressure of the application prior to installation.

4. Install lubricator unit into adapter (B).

5. Install reducers, extensions, grease line, etc. (if necessary).

6. Screw a pressure manometer into the lubrication point (dd)

IG. 1, page 6).

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.

Tee Fitting Stop Valve Lube Point Lubricator ON / OFF Switch

7. Ensure the stop valve (cc) of the pressure manometer is open.

8. Attach lubricator and adapter (B) to the pressure manometer (aa - cc) and turn the switch to “ON” (ff) (F

IG. 1).

9. Run the manometer for about 20 seconds. Observe the gauge and repeat this procedure until the pressure registered on the gauge stays constant.

10.To determine the counter pressure, wait approximately 5 minutes until the system has relaxed. Do one

more discharge by turning the unit OFF; then ON again until it dispenses for no more than 5 seconds.

12.To disconnect lubricator from manometer, follow pressure relief procedure provided on page 4.

NOTE: In this application, you will be disconnecting adapter (B) from manometer instead of lubrication point.

NOTICE

Do NOT disconnect lubricator from adapter (B). Screwing anything into lubricator end a second time will damage self-sealing threads.

13.If the counter pressure is 5 bar (72.5 psi) or higher, flush the lubrication point with a grease gun.

If the counter pressure does not decrease you may need a different lubricant or size lubricator canister. Contact Graco Customer service for assistance.

Priming/Prefilling Fittings and Grease Lines

All accessories and grease lines must be primed/pre filled. Without this priming/pre filling, the lubricator would first have to fill the accessories with lubricant.

Example: A tube that is one meter long requires about 28 cm3 of lubricant. It would

take the lubricator with a 12 month setting and an EM-120 grease canister about 3 months to fill this 1 meter tube.

IG. 2 illustrates one way to pre fill using a

F grease gun to dispense the grease.

11.Wait approximately 5 more minutes to make sure the system does not lose pressure and remains constant.
