Warnings
335023F 3
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 or on warning labels, 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.
+
SKIN INJECTION HAZARD
High-pressure fluid from injector, 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 put your hand over the fluid outlet.
• Do not stop or deflect leaks with your hand, body, glove, or rag.
•Relieve pressure before cleaning, checking, or servicing equipment.
• Tighten all fluid connections before operating the equipment.
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 eyewear, and hearing protection.
• Respirators, protective clothing, and gloves as recommended by the fluid and solvent manufacturer.
CALIFORNIA PROPOSITION 65
This product contains a chemical known to the State of California to cause cancer, birth defects or other
reproductive harm. Wash hands after handling.
WARNING

Installation Instructions
4335023F
Installation Instructions
Reference letters used in the following instructions, refer
to FIG. 1.
• Group injectors to minimize feed line length.
• Install injectors in locations that allow easy servicing
access.
• To avoid injector damage install injectors in areas
away from moving equipment.
• Injector outputs can be combined for a common
bearing point with a large grease requirement but
the output for a single injector cannot be split into
multiple bearing points.
• Graco recommends using steel tubing instead of
pipe and hose for supply lines when possible. Pipe
is often contaminated with scale and requires
proper cleaning prior to use. Hose lines expand
under pressure which leads to longer pump cycle
time.
NOTE: The equipment may be pressurized by an auto-
matic lube cycle initiated by a lubrication controller
(timer).
1. Before installing the injectors, disconnect and iso-
late the power supplies to the lubrication controller
and to the pump.
2. Relieve pressure. See the pressure relief procedure
provided in the pump manual for your system.
3. Install injectors on a flat, hard surface using holes
(a) (FIG. 1) in manifold.
4. Connect fluid supply line to injectors.
5. Connect lube point feed lines to outlet (b).
6. Flush the system with low viscosity oil or mineral
spirits to remove contamination introduced during
installation.
7. Use a purge gun or run the pump until clean lubri-
cant is dispensed at the end of each feed line to
purge the system of flushing fluid or air.
8. Run the system at full output and verify that all injec-
tors are cycling.
9. Adjust injector volume output. (See Volume Adjust-
ment page 5.)
10. Connect feed lines to lubrication points.
Injector Cap (FIG. 2)
1. Apply a light coating of transparent lubricant to the
inside of cap (c).
2. Slide the o-ring (d) over the indicator stem of the
injector and into the groove.
3. Slide cap (c) down over the indicator stem of the
injector.
NOTICE
Contaminants can damage the seal packing. To
prevent damage to the seal, a filter should be
installed in the grease supply line.

Volume Adjustment (FIG. 3)
Maximum adjustment setting is when adjusting screw
(2) is just making contact with the indicator pin (8),
(inside, not shown) with no inlet pressure. Turn adjusting
screw (2) clockwise, to reduce output. To adjust, loosen
lock nut (3) and turn adjusting screw (2) the number of
turns indicated on the GL-1 X or GL-1 XL Volume Out-
put Guide to obtain the desired volume. Tighten lock nut
(3) when desired volume setting is reached.
