Follow these safety precautions when operating the PACER INDUSTRIAL MIXERS Dual arm or Single arm
mixers.
Installation
1. Before operating the machine, read this Owner’s manual carefully.
2. Ground the machine properly. Be sure to follow proper grounding and electrical procedures.
3. Avoid dangerous environments. Do not use the machine in a damp or wet environment.
4. Use the proper power source. Refer to the machines designation label located on the back of the machine.
If it is unreadable call our customer service department (1-888-236-1143) before connection the mixer to a
power source.
5. Avoid extension cords. To minimize the risk of circuit overload, or improper electrical grounding do not
use extension cords.
Operation
6. Ensure the can being mixed is securely clamped.
7. Keep customers away from mixing area. Only trained personnel should operate the mixer.
Maintenance
8. Do not get the timer, control panel or wiring wet. Failure to do so could result in electric shock.
9. Clean all surfaces of the machine with soap and water. Do not use any solvent-based cleaners or thinners.
10. Disconnect machine from power source before cleaning or servicing mixer.
11. Be sure to maintain the mixer on a regular basis. Follow the maintenance procedures on page 8.

The PACER INDUSTRIAL MIXERS Dual arm and Single arm mixers are shipped fully assembled. The ma-
chine must be mounted to the PACER INDUSTRIAL MIXERS Floor Stand or Counter Stand. Failure to do so
will void the warranty. Refer to the instructions below.
Installing the mixer on the Counter Stand.
1. Assemble the Counter Stand castings to the mixer using the hardware provided.
2. Insert a rubber foot into the top and bottom of each spring.
3. Insert a spring and foot assembly into the recess in the bottom of each corner of the Counter Stand castings.
4. Plug the power cord into a grounded receptacle (see page 7).
Note: Explosion proof models are not furnished with a power cord. The machine must be hard wired to
the power source by a qualified electrician.

Installing the mixer on the Floor Stand.
1. Assemble (8) suction cups to the bottom of the floor stand using the hardware provided.
2. Assemble the mixer and (4) isolators (provided with the mixer) to the Floor Stand using the hardware pro-
vided.
3. Plug the power cord into a grounded receptacle (see page 7).
Note: Explosion proof models are not furnished with a power cord. The machine must be hard wired to
the power source by a qualified electrician.
4. If the suction cups do not grip the floor properly the base may creep while the mixer is operating. If this
does occur, anchor the base to the floor with rubber cement:
A. Tilt the mixer and floor stand until you can fit two 2” x 4” boards under the floor stand. This will lift
the suction cups far enough off the floor to apply rubber cement. Make sure the boards do not touch the
suction cups.
B. Clean the floor directly under the suction cups. Clean the contacting surface of the suction cups.
C. Apply rubber cement to the contacting surface of the suction cups and the floor directly under the suc-
tion cups.
D. Allow the rubber cement to dry until it becomes tacky. Remove the boards and lower the floor stand to
the floor.
E. Allow the rubber cement to dry overnight before running the mixer.
If you ever need to move the mixer, you can break the bond by inserting a wall scraper between the suction cup
and the floor.

Your mixer MUST BE PROPERLY GROUNDED. If there is an electrical short circuit, grounding reduces
the risk of electric shock.
The machine’s power cord has a grounded plug. This plug must be inserted into an electrical outlet that is
properly installed and grounded according to all local codes and ordinances.
If you must repair or replace the power cord or plug, do not connect the grounding wire to either flat-blade ter-
minal. The wire with insulation having an outer surface that is green (with or without yellow stripes) is the
grounding wire. Check with a qualified electrician if you don’t completely understand these grounding instruc-
tions, or if you are not sure whether the machine is properly grounded. DO NOT MODIFY the plug provided:
if it won’t fit the outlet, have a proper outlet installed by a qualified electrician.
Extension Cords
Avoid using extension cords. If an extension cord is unavoidable, consult a qualified electrician to determine
what type of extension cord will satisfy the grounding, current capacity, and other requirements of the particu-
lar situation.
RISK OF ELECTRIC SHOCK.
ALWAYS HAVE MACHINE PROPERLY
GROUNDED.

Safety Precautions
1. Before operating the machine, read this Owner’s manual carefully. For special air-driven model instruc-
tions see page 9.
2. Ground the machine properly. Be sure to follow proper electrical connection and grounding requirement
procedures.
3. Non-explosion proof models only: Do not use in hazardous environment where dust or flammable va-
pors are present. Do not mix flammable materials or materials with a low flashpoint per the material
safety data sheet.
4. Make sure can lids are tightly closed.
5. Do not mix breakable containers such as glass, porcelain, etc.
6. Ensure container is securely clamped.
7. All customers should be kept away from the work area.
8. The mixer should be operated by trained personnel only.
NOTE: The motor is protected by a thermal overload cutoff switch. If the temperature of the motor gets too
hot it will automatically shut off. The motor will not start again until it has cooled down.
Mixing Procedure
1. Turn the clamp handle counter-clockwise to open the clamp.
2. Place the container to be mixed in the clamp and turn the clamp handle clockwise until the container is se-
cured.
3. If mixing only one container on a dual mixer clamp an empty can (or a piece of 2” x 4” board) in the other
clamp.
4. After the containers are secured, set the timer for desired mix time.
5. The mixer will turn off after the mix time has elapsed.
Maintenance Procedures
Always disconnect machine from power source before maintaining or servicing.
Cleaning:
Keep the machine clean. Colorant or paint spilled on the machine can be cleaned with warm soapy water and/
or mineral spirits. After washing, oil the clamp rods and clamp lead screw to prevent rusting. Be careful not to
get the control panel or timer wet.
Lubrication:
Keep the clamp rods and clamp lead screw free of dirt, dried paint, and other materials. Remove any small
nicks with a fine file. Once a week apply a thin film of oil to the clamp rods and clamp screw.

The Instructions in this manual apply to both electrically powered and air driven models, with the exceptions
noted below.
Installation
Air Supply
Fill the Lubricator reservoir with an SAE-10W motor oil.
Connect a 10-cfm air supply to the inlet side of the ball valve and filter on the front of the mixer.
The regulator is factory set at 100psi.
The air supply must be at least 100psi to reliably operate the machine, and must not exceed 200psi.
Air driven models require no electrical connection.
Operation
Mixing Procedure
Air-driven models don’t have a timer. Control the mixing time by turning the air supply on and off.
Flammable materials may be mixed in air-driven models.
Maintenance
Cleaning
In addition to cleaning instructions on page 8, replace the air filter element when dirty. Replacement filter ele-
ments are available from you local Aro pneumatic supplies dealer.

timer.
Broken, worn or loose drive belt. Visually inspect drive belt and replace
if necessary.
Worn or damaged clamp plate. Replace clamp plate.
Clamp lead screw and/or clamp rods
need to be lubricated. Apply a thin film of oil to clamp screw and clamp rods.
Worn or damaged clamp plate. Replace clamp plate.
Faulty timer. Have a qualified electrician replace
timer.
Clamps are not positioned properly in
relation to the counterweight on pulley. With the clamps in a horizontal posi- tion, counterweight on pulley should be
in the 9 o’clock position.
