Important Safety Instructions
Read all warnings and instructions in this manual and related automatic lubrication system instruction manuals. Save all instructions.
SKIN INJECTION HAZARD
Fluid from the injector, leaks, or ruptured components can inject fluid into your body and cause extremely seri­ous injury, including the need for amputation. Fluid injected into the skin might look like just a cut, but it is a serious injury. Get immediate surgical treatment. Fluid splashed in the eyes or on the skin can also cause serious injury. The equipment may be pressur­ized already, or it could become pressurized by an automatic lube cycle initiated by Lubrication Controller (timer). Disconnect power to the timer, and disconnect the air supply to the pump module to ensure that the system is depressurized. See the pressure relief pro-
cedure in the pump manual incuded with your auto­matic lubrication system.

Installation Instructions

Reference letters used in the following instructions, refer to F
IG. 2.
Group injectors to minimize feed line length.
Install injectors in locations that allow easy and safe servicing access.
Install injectors in areas that minimize accidental injector damage by 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.
2. Install injectors on a flat, hard surface using mount­ing brackets (a).
3. Connect fluid supply line (c) to injectors.
NOTICE
To prevent rupturing supply lines due to over-pres­surizing the components, only use supply lines and fittings that meet or exceed the pressure rating of the injectors.
4. Connect lube point feed lines (b).
5. Flush the system with low viscosity oil or mineral spirits to remove contamination introduced during installation.
6. Use a purge gun or run the pump until clean lubri­cant is dispensed at the end of each feed line to purge the system of flushing fluid or air.
7. Run the system at full output and verify that all injec­tors are cycling.
1. Relieve pressure. See Pressure Relief Procedure,
in the pump instruction manual included with your automatic lubrication system.
8. Adjust injector volume output. (See Volume Adjust­ment page 4.)
9. Connect feed lines to lubrication points.

Plastisol cap for Graco GL-1 Injectors

Item Description Qty
21 Plastisol cap 1 22 O-ring 1
Installation Instructions
1. Apply a light coating of transparent lubricant to the inside of cap (21).
2. Slide cap (21) over the indicator stem of the injector far enough to cover the groove in the piston plug.
3. Slide the o-ring (22) down over the cap to the groove in the piston plug, forcing the cover into the groove to form a seal.
Volume Adjustment
*Maximum adjustment setting is when adjusting screw (2) is just making contact with the indicator pin (8) with no inlet pressure. Turn adjusting screw clockwise (in), to reduce output. To adjust, loosen lock nut (3) and turn adjusting screw (2) the number of turns indicated on the GL-1 Volume Adjustment Table to obtain the desired volume. Tighten lock nut (3) when desired volume setting is reached
