hazard symbols and warnings not covered in this section may appear throughout the body of this manual where
applicable.

WARNING
WARNING

+

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.
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. 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.
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.
•

2

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

Auto-Fill Shut Off Overview

Auto-Fill Shut Off
Overview

Pressure Relief
Follow the Pressure Relief Procedure whenever
you see this symbol.

Reference letters used in the following instructions refer
to Parts Table and Drawing shown on the cover of this
manual.
The Auto-Fill Shut Off is used for refilling the grease
tank/reservoir in an automatic lubrication system. As
grease is added to the reservoir, it pushes the diaphragm up to the top of the reservoir. The diaphragm
then pushes the valve pin and closes the inlet fluid path.

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 when you stop dispensing and before
cleaning, checking, or servicing the equipment.
To relieve pressure in the system, use two wrenches
working in opposite directions on pump outlet fitting to
slowly loosen fitting only until fitting is loose and no
more lubricant or air is leaking from fitting. See FIG. 1.

•

Fill tube (outer): directs grease to the bottom of
the pump during the fill operation. As grease is
filled into the reservoir, the diaphragm moves
up. When the grease level in the reservoir has
reached full, the diaphragm pushes the valve
pin up, closing off fluid path, ending the fill operation.

•

Pump tube (inside): when pump is operating,
grease is drawn out of the bottom of the pump
reservoir, through the pump tube and dispensed
to the lubrication points.

COMPONENT RUPTURE HAZARD
The maximum working pressure of each component
in the system may not be the same. To reduce the
risk of overpressurizing any component in the
system, be sure you know the maximum working
pressure of each component. Never exceed the
maximum working pressure of the lowest rated
component in the system. Overpressurizing any
component can result in rupture and/or property
damage and serious injury.
Regulate pressure to the pump so that no fluid line,
component or accessory is over pressurized.

the following Remote Filling Station Pressure Relief
procedure:

Close ball valve (bv) when all pressure has
been relieved.
NOTE: The pin may not drop and the Auto-Fill
may not reset because the tank is full. However,
when the pump begins using the grease, the pin
resets. The pin must reset before the next cycle
of refilling.

Remote Filling Station Pressure Relief
The following Pressure Relief Procedure is only
used with the Auto-Fill Shut Off Valve to relieve
remote filling station and lubricant supply line
pressure.

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 when you stop dispensing and before
cleaning, checking, or servicing the equipment.
a. To relieve pressure between the refill pump and
Auto-Fill Shut Off, open ball valve (bv) (FIG. 19).
Pressure will be released and excess fluid will
drain out of the drain tube (dt) and into the lubrication collection container (H).
