WARNING
EQUIPMENT MISUSE HAZARD
Equipment misuse can cause the equipment to rupture or malfunction and result in serious injury.
D This equipment is for professional use only.
D Read all instruction manuals, tags, and labels before operating the equipment.
D Use the equipment only for its intended purpose. If you are not sure, call your Graco distributor.
D Do not alter or modify this equipment.
D Check equipment daily. Repair or replace worn or damaged parts immediately.
D Handle hoses carefully. Do not pull on hoses to move equipment.
D Route hoses away from traffic areas, sharp edges, moving parts, and hot surfaces. Do not expose
Graco hoses to temperatures above 66_C (150_F) or below –40_C (–40_F).
D Comply with all applicable local, state, and national fire, electrical, and safety regulations.
D Use only hand-powered pumps to fill the booster gun with lubricant.
WARNING
INJECTION HAZARD
Spray from the valve, leaks or ruptured components can inject fluid into your body and cause extremely serious injury, including the need for amputation. Fluid splashed in the eyes or on the skin can
also cause serious injury.
D Fluid injected into the skin might look like just a cut, but it is a serious injury. Get immediate medical attention.
D Do not point the valve at anyone or at any part of the body.
D Do not put your hand or fingers over the grease fitting coupler.
D Do not stop or deflect leaks with your hand, body, glove or rag.
D Tighten all fluid connections before operating the equipment.
D Check the hoses, tubes, and couplings daily. Replace worn or damaged parts immediately.
Do not repair high pressure couplings; you must replace the entire hose.
TOXIC FLUID HAZARD
Hazardous fluid or toxic fumes can cause serious injury or death if splashed in the eyes or on the skin,
inhaled, or swallowed.
D Know the specific hazards of the fluid you are using.
D Store hazardous fluid in an approved container. Dispose of hazardous fluid according to all local,
state and national guidelines.
D Always wear protective eyewear, gloves, clothing and respirator as recommended by the fluid and
solvent manufacturer.

Operation
Operating the Gun
WARNING
The maximum delivery pressure of the lubricator
gun, when charged and disconnected from the
dispenser, is 10,000 psi (700 bar). Fluid emitted
under such high pressure can cause serious injury.
See the warnings on page 3.
NOTE: Numbers and letters in parenthesis refer to
callouts in the Figures and Parts Drawing.
Filling the Gun (See Fig. 1)
WARNING
1. Wipe clean the coupler (A) and the grease fitting
on the part you are lubricating.
2. Connect the coupler and fitting.
3. Continuous delivery:
Keep the supply pump hose connected to the gun.
Squeeze the gun handle and continue pumping the
supply pump handle to provide a constant flow of
fluid.
High pressure delivery, or remote dispensing:
Be sure the supply hose is disconnected. Squeeze
and release the gun handle one or more times until
the part is well lubricated.
To avoid serious injury, use only hand–powered
pumps to fill this gun with lubricant.
1. Connect a hose from the hand-powered lubricant
supply pump to the grease fitting (2).
2. Without squeezing the handle (12), pump the
supply pump handle until lubricant flows through
the adapter (A).
3. Disconnect the supply hose by twisting the coupler
to one side.
CAUTION
To avoid damaging the coupler, do not pull it straight
off. Make sure that you twist the coupler while removing it.
WARNING
Never force lubricant into a fitting. If the lubricant is
not flowing, or the coupler clogs, STOP
DISPENSING IMMEDIATELY. Forcing lubricant
may cause excessive back pressure, which could
cause component rupture and serious injury.
Replace damaged grease fittings.
NOTE: Most “frozen” fittings are caused by dirt, rust,
scale, poor lubrication, or neglect. Replace damaged
fittings before continuing.
