Warnings

3A2100K 3

Warnings

The following warnings are for the setup, use, grounding, maintenance, and repair of this equipment. The exclama-

tion 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

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 solvent 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.

•Stop operation immediately if static sparking occurs or you feel a shock.Do not use equipment until

you identify and correct the problem.

• Keep a working fire extinguisher in the work area.

SKIN INJECTION HAZARD

High-pressure fluid from dispensing device, hose leaks, or ruptured components will pierce skin. This

may look like just a cut, but it is a serious injury that can result in amputation. Get immediate surgical

treatment.

• Do not point dispensing device at anyone or at any part of the body.

• Do not put your hand over the fluid outlet.

• Do not stop or deflect leaks with your hand, body, glove, or rag.

• Follow the Pressure Relief Procedure when you stop dispensing and before cleaning, checking, or

servicing equipment.

• Tighten all fluid connections before operating the equipment.

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

Warnings

43A2100K

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 com-

ponent. 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.

• Do not leave the work area while equipment is energized or under pressure.

• 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 manufac-

turer’s replacement parts only.

• Do not alter or modify equipment. Alterations or modifications may void agency approvals and create

safety hazards.

• Make sure all equipment is rated and approved for the environment in which you are using it.

• 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.

MOVING PARTS HAZARD

Moving parts can pinch, cut or amputate fingers and other body parts.

• Keep clear of moving parts.

• Do not operate equipment with protective guards or covers removed.

• Pressurized equipment can start without warning. Before checking, moving, or servicing equipment,

follow the Pressure Relief Procedure and disconnect all power sources.

PERSONAL PROTECTIVE EQUIPMENT

Wear appropriate protective equipment when in the work area to help prevent serious injury, including

eye injury, hearing loss, inhalation of toxic fumes, and burns. This protective equipment includes but is

not limited to:

• Protective eye wear, and hearing protection.

• Respirators, protective clothing, and gloves as recommended by the fluid and solvent manufacturer.

*The GBL7500 Box Lubricator Pump and GBL Shaft Rota-

tion/Low Level Alarm Pump are available from Graco. See

Accessories/Other Accessories, page 12 for information about

these pump models and the related instruction manual.

Grounding

1. Loosen grounding screw (a) (FIG. 2) and place one

end of a 12 gauge (1.5mm) minimum ground wire

between the grounding screw and washer (b).

2. Tighten grounding screw (a) securely.

3. Connect other end of wire to a true earth ground.

Installation Procedure

Reference letters used in the following instructions,

refer to FIG. 1.

1. Select a mounting surface that satisfies the follow-

ing:

• Is able to support the weight of the reservoir

and fluid when filled to capacity.

NOTE: When possible, mount to a surface that

experiences little or no vibration.

• Allows easy access to the lubricator for filling

the reservoir and periodic maintenance.

• The lubricator must be connected to a ground

source.

2. Install reservoir to the mounting surface. See

mounting hole layout in the Reservoir and Mounting

Dimension section of this manual, page 14.

3. Install bolts through holes (F) in reservoir mounting

bracket and tighten securely.

Modular box lubricators are not approved for use

in hazardous locations or explosive atmospheres

unless all accessories, components and wiring

meet all local and national codes.

FIG. 1

ti17757

The equipment must be grounded to reduce the risk

of static sparking. Static sparking can cause fumes

to ignite or explode. Grounding provides an escape

wire for the electric current.

FIG. 2

Installation

63A2100K

4. Remove fill cap (B) and fill reservoir with clean, fil-

tered fluid until it reaches the full line on the sight

glass.

NOTE:

• Filter oil with a minimum 25 micron strainer.

Depending on machine requirements it may be

necessary to maintain a higher cleanliness

level.

• A pump blank is provided to install over all

unused pump stations.

• Refer to pump instruction manual for pump

installation and priming instructions. (See

page 12 for Graco pump model information.)

Drive Mechanism

A 5/8 in. diameter shaft is provided to connect the lubri-

cator to a rotary power source. A woodruff key and key

way on the shaft are provided to aid in connecting this

source.

Install protective guards around all drive components

upon installation.

Refilling the Reservoir

When necessary, fill the lubricator reservoir with clean

filtered lubricant until it reaches the fill line on the sight

glass. A sight level gauge is provided on the reservoir to

monitor the fluid level. The oil level should not be

allowed to drop below the line indicating an empty res-

ervoir.

Pressure Relief Procedure

Follow the Pressure Relief Procedure whenever

you see this symbol.

1. Stop lube pump.

2. If installed, close oil supply valve located upstream

from pump.

3. If installed, open drain valve located downstream

from the pump.

4. Slowly crack open fluid line fittings to relieve pres-

sure.

Service/Maintenance

1. Follow the Pressure Relief Procedure before per-

forming any service procedures.

2. Lubricator operation can be checked by observing

the drip tube located within the sight glass well of

your pump.

• If the correct pumping rate is maintained, no

servicing is required other than periodic replen-

ishment of the reservoir.

• If the sight glass well pumps dry or no flow is

observed refer to the Troubleshooting Section,

page 8.

3. Inspect box for worn or damaged components.

Replace as necessary.

Notice

The recommended speed of the box lubricator cam

shaft is 3 - 50 rpm. Do not exceed the maximum

value of 50 rpm to avoid pump damage.

This equipment stays pressurized until pressure is

manually relieved. To help prevent serious injury

from pressurized fluid, such as skin injection,

splashing fluid and moving parts, follow the

Pressure Relief Procedure in your pump manual

when you stop dispensing and before cleaning,

checking, or servicing the equipment.

4. Clean lubricator periodically to eliminate contami-

nation that may have occurred in the oil. To accom-

plish this:

a. Drain reservoir by removing drain plug (C) (FIG.

1). Dispose of oil according to all applicable

safety regulations.

b. Remove all pumping units.

c. Clean the pumps and reservoir by brushing

loose all foreign matter, dipping in solvent and

blowing dry with compressed air.

d. Replace pumping units. Torque mounting

screws (J) to 110 in. lbs + 10 in. lbs. (12.43 N.m

+ 1.13 N.m).

e. Apply thread sealant (user supplied) to drain

plug (C) (FIG. 1) and replace. Torque to 35 in.

lbs + 5 in. lbs. (3.95 N.m + 0.6 N.m).

f. Fill reservoir. (See Refilling the Reservoir, page

6).
