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.
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.
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.
• Ground all equipment in the work area.
• 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.
• 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.

Warnings
332023A 3
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 Specifications in all equipment manuals.
• Use fluids and solvents that are compatible with equipment wetted parts. See Technical
Specifications in all equipment manuals. Read fluid and solvent manufacturer’s warnings. For
complete information about your material, request Safety Data Sheets (SDSs) 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.
PRESSURIZED ALUMINUM PARTS HAZARD
Use of fluids that are incompatible with aluminum in pressurized equipment can cause serious
chemical reaction and equipment rupture. Failure to follow this warning can result in death, serious
injury, or property damage.
• Do not use 1,1,1-trichloroethane, methylene chloride, other halogenated hydrocarbon solvents or
fluids containing such solvents.
• Do not use chlorine bleach.
• Many other fluids may contain chemicals that can react with aluminum. Contact your material
supplier for compatibility.
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. 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.

Installation
Pressure Relief Procedure
Follow the Pressure Relief Procedure whenever
you see this symbol.
1. Disable the pump’s pneumatic air supply.
2. Relieve pressure by slowly loosening the outlet
connection fitting.
General Information
Both the MSA-10 and MSA-100 are air-operated
pumps with an adjustable volume output. They are
designed for use in series progressive oil or grease
lubrication systems.
The lubricant can be supplied to both pumps by either
a gravity feed reservoir or by a pressurized source,
such as a bulk header that exerts up to 500 psi (3.45
MPa, 34.5 bar) at the pump inlet.
NOTE: When connected to a pressurized supply,
backflow to supply must be permitted.
Both the MSA-10 and the MSA-100 are supplied as a
single acting pump and can be field-converted to a
double-acting pump.
NOTE: Typical installation requires a controller
operated, directional air valve since the pump’s
pneumatic piston requires venting on the return stroke
to complete a fully cycle.
The pumps come standard with a rupture to
atmosphere indicator rated to 1450 psi (10 MPa, 100
bar) and an outlet check valve. Higher pressure rating
rupture discs can be purchased separately. If the
indicator needs repairs due to a ruptured disc:
1. Remove the top nut from the indicator housing.
2. Remove the ruptured disc and replace with a new
disc.
3. Replace the top nut, torque to 5 ft-lb (6.8 N•m).
Mount the Pump
See FIG. 1 for reference letters used in this section.
MSA-10 Air Operated Pump
1. Mount the pump to a flat, sturdy surface using two
(2) 5/16 in. screws through the mounting holes (J).
2. Connect the lubrication inlet and outlet lines to the
pump inlet (K) and outlet (L). Do not use PTFE type
tape.
3. Connect the air supply line to the pump air inlet (G),
which is marked “S.A.” on the pump body. If a
higher air flow creates a cycle rate that exceeds the
maximum allowed, an inlet restrictor valve is
required (P/N 563072).
• When using the MSA-10 Air Operated Pump as a
double-acting pump, remove the plastic vent plug
from the double-acting inlet port (H), which is
marked “D.A.” on the pump body, and connect a
second air supply line to that inlet.
4. Cycle the pump until all of the air is removed and
the lubricant runs clear at the outlet.
5. Adjust the pump output:
a. Remove the adjustment screw cap (P).
b. Turn the adjustment screw (N):
- Clockwise to reduce output
- Counter-clockwise to increase output
c. When adjusted to desired amount, replace the
adjustment screw cap (P).
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 spraying and before
cleaning, checking, or servicing the equipment.

Installation

MSA-100 Air Operated Pump
See FIG. 2 for reference letters used in this section.
1. Mount the pump to a flat, sturdy surface using four
(4) 3/8 in. screws through the mounting holes (P).
2. Connect the lubrication inlet and outlet lines to the
pump inlet (N) and outlet (M).
• Seal all of the pipe connections. Do not use PTFE
type tape.
3. Connect the air supply line to the pump air inlet (H).
If a higher air flow creates a cycle rate that exceeds
the maximum allowed, an inlet restrictor valve is
required (P/N 563072).
• When using the MSA-100 Air Operated Pump as a
double-acting pump, remove the air muffler from
the double-acting inlet port (J), which is marked
“D.A.” on the pump body, and connect a second air
supply line to that inlet.
4. Cycle the pump until all of the air is removed and
the lubricant runs clear at the outlet.
5. Adjust the pump output:
a. Remove the adjustment screw cap (K).
b. Turn the adjustment screw (L):
- Clockwise to reduce output
- Counter-clockwise to increase output
c. When adjusted to desired amount, replace the
adjustment screw cap (K).
