Equipment Protection Quick Facts
1. Inspect Upon Delivery: FIRST! Inspect for missing or damaged components. See “Initial Set-Up” section for where to
report missing or damaged parts.
2. Electrical Service: Only connect unit to a 230V line with adequate line amperage (25A ). Do not connect air compressor to
a 208V 3-phase system. A 208V system can provide low voltage and damage the air compressor. When installing the air
compressor, one must check that the voltage at the terminal is no lower than 208V.
3. Check Pump Oil: Pump is shipped with oil. Check the pump oil level before starting. See “ Preparing for Operation ”
section of this Owner’s Manual for capacity and viscosity.
4. Use Mechanical Lifting Equipment: Compressor is shipped on a pallet and is too heavy to handle manually. Use proper lifting
equipment for unloading and moving to installation site.
5. Install Using a Qualified Electrician: All wiring, grounding, and electrical connections must be made by a qualified electrician.
Install according to local and national codes.
6. Install a Regulator: We recommend installing a regulator on the compressor at each distribution point to maintain constant
pressure in the outlet hose line and provide reduced pressure appropriate for air tool being used.
7. Run Pump Unloaded for Break-in Period: Before initial use, open ball valve and run compressor for 30 minutes to break in
pump parts.
8. Follow Maintenance Schedule: Pump, air filter, and tank require periodic inspection and servicing to provide efficient function
and long life. See “ Maintenance Schedule ” for frequency of servicing.

Step 1. Inspect & Unpack
Upon receipt, inspect air compressor for missing or damaged parts. Verify that it is the compressor you ordered.
See “Component Identification” section of this manual for a diagram of the compressor and its components.
For missing or damaged components, please contact Product Support at 1-877-761-2819.
If complete, fill out product serial number information. See “Limited Warranty” section of this manual.
Step 2. Assembly
Attach Air Filter
1. Remove air filter from manual bag.
2. Remove plastic plug from air compressorinlet. (Figure 1)
3. Unscrew wing nut, remove washer and air filter housing from base.
(Figure 2)
4. Screw base into air compressor inlet as shown.
Tighten with appropriate tool on specified location.
(Figure 3 & Figure 4)
5. Replace air filter housing and washer. Secure with wing
nut, hand tighten only. (Figure 5)
Attach Regulator (Recommended)
We recommend using a regulator with this compressor since the pre-set tank pressure ranges between 145 PSI and is usually
greater than what is needed by tools.
Without the addition of a regulator, the pressure switch will maintain a tank pressure within the pre-set range that has a max of
145 PSI. This is considered an overly high pressure for many tools. A user-installed regulator can maintain a lower constant
pressure in the outlet hose line and prevent over pressurization of tools.
WARNING: Bursting hazard
Too much air pressure causes a hazardous risk of bursting. Check the manufacturer’s maximum pressure rating for air tools
and accessories. Regulators must never be set to exceed the maximum pressure rating of tank or tools.

Step 3. Select Suitable Location
WARNING:Lifting hazard
The compressor is heavy. Ensure that proper lifting equipment is available to unload and move compressor to installation site.
Location Criteria:
Location must be inside an enclosed building
Where no flammable vapors, dusts, andgases are present.
At least 15” away from walls and other objects.
Away from other heat-generating equipment.
Away from dusty/dirty conditions.
In a well illuminated area.
Where proper wire size is already, or canbe made, available.
Positioning:
The compressor should be mounted on a dry, firm, and level surface. It must sit level and be stabilized since it
will slide or shift during operation if not secured.
Airflow:
Provide access to adequate, clean and unobstructed airflow for cooling and airsupply.
Remember the supply air is passing throughthe compressor supply hoses and tools. These can be damaged or
have a shortened life if unclean air is present or air filter is not clean and functioning properly.
Do not allow debris to accumulate orblock airflow.
Do not operate with a tarp, blanket, or cover surrounding the machine, which blocks airflow.
Do not place any objects against or on top of the unit, which can also block airflow or damageunit.
Electrical:
MUST be connected to a 230 Volt, single-phase outlet having operating capacity of 25 amps
Wiring:
Proper wire size should take intoconsideration length from distribution panel.
See Step 6 , “Wiring Installation ” for more information.
Ideal operating temperatures:
40° and 100°F (4° and 37°C).
Operating Limitations:
15°F (-9°C) or above 125°F (52°C).
If temperatures consistently drop below 32° F (0°C), install within a heated building. If this is not possible, protect the
safety/relief and drain valves from freezing.
Note: Excessive moisture is likely to occur if unit is stored in an unheated area subject to large temperature changes.
Moisture forming in pump can produce sludge in the oil, causing parts to wear out prematurely. Excessive condensation on
the pump when it cools down is a sign that this may be occurring.
Step 4. Permanent Mounting
You will permanently mount the compressor after selecting the location in Step 3.
1. On a concrete pad or other stable mounting platform, drill 4 holes according
to given in the diagram below. (Figure 6)
Figure 6

2. Unbolt the compressor feet by removing the bolts, washers and nuts.
Discard them after removal. (Figure 7)
3. Lift and remove the compressor from the pallet using a hoist.
4. Situate unit in chosen location and bolt in place. (Use 5/8”bolts and
washers. Make sure bolts are long enough to provide a good anchor point.)
Bolt it in place to prevent unit from vibrating excessively. Use metal shims
under the “short”feet if necessary.
5. A rubber isolation mat or pads may be used under each mounting foot to
reduce vibration.
Step 5. Installing Distribution Piping
The stationary compressor can utilize the same type of properly rated, single flexible hose, as is used on portable air
compressors. However, many purchasers will prefer to utilize the stationary unit through a permanently installed distribution
system serving several points within a facility. The design, installation and usage of stationary compressed air distribution
systems has been the subject of extensive industrial, trade and government attention, as can be seen within many private and
government websites.
An example of the typical components used in
a permanent distribution system are shown in
Figure 8.
It should be obvious that there is considerable
complexity in designing and installing such a
system. Controlling the pressures, moisture in
the air, drying components, contaminants,
lubrication, as well as choosing and sizing the
piping for the system, requires the expertise of
persons or firms familiar with such designs and
their installation.
A very significant safety issue arises when one is
distributing line pressure air throughout a facility,
which is over 150 PSI. Standard components,
steel pipe fittings and many plastic compressed
air piping systems are only rated to 150 PSI and
cannot be safely used in such distribution systems.
In such cases, immediately regulating the
distribution line pressure at the compressor outlet
to under 150 PSI (usually in the 90-120 PSI range)
is mandatory for many compressed air piping systems.
Recommends that you contact plumbers or mechanical contractors with expertise in compressed air systems to plan and/or
install your distribution system.
WARNING: Bursting hazard
This unit can produce pressures in excess of 150 PSI, which is beyond the capabilities of many piping types and pipe fittings.
Failure of undersized and/or inadequate distribution components can lead to serious injury.
WARNING: Restriction hazard
If an after cooler, check valve, block valve, or any other restriction is added to the compressor discharge, install a properly sized
ASME approved pressure safety/relief valve between the compressor discharge and the restriction.

Step 6. Wiring Installation
Wiring should be installed by a qualified electrician. Installations must be in accordance with all applicable local, state, and
federal regulations.
WARNING: Electrical Shock Hazard
Improper electrical grounding can result in a risk of electric shock. Electrical installation and service of the 230V, single-phase
box (25 amp) MUST be made by a qualified electrician. If the compressor must be reinstalled at a different location, the re-
connection should also be made by qualified personnel. The compressor motor may not start or may burn out prematurely if
adequate amperage or voltage is not available.
Electric Compatibility
The motor rating, as shown on the motor nameplate and the building power supply must have compatible voltage, phase and
hertz characteristics.
Wire Size
The electrical wiring required between the building’s power supply and the electric motor varies according to motor horsepower.
Power leads must be adequately sized to protect against excessive voltage drop during start-up. High voltage drops can cause
motor to overheat and fail. A qualified electrician should provide information for selecting proper wire size. If other electrical
equipment is connected to the same circuit, the total electrical load must be considered in selecting the proper wire size. DO
NOT use undersized wire.
CAUTION: Inadequate wiring hazard
Overheating, short-circuiting and fire damage will result from inadequate wire sizing.
Circuit Breaker
Your electrician will need to refer to the National Electric Code to determine the proper circuit breaker rating required. When
selecting a circuit breaker, remember the momentary starting current of an electric motor is greater than its full load current.
Time-delay or “slow- blow” circuit breakers are recommended.
Grounding
This product and its associated conduit and junction box must be grounded.
Do not ground to a gas supply line.
WARNING: Electrical shock hazard
Improperly grounded motors are shock hazards. Make sure all equipment is properly grounded. Check with a qualified
electrician if you are in doubt as to whether the outlet is properly grounded.
Model #TMG-ACE60 (230 Volt; 5 HP)
You will recognize this unit since it has a motor reset button.
The electric lines can be connected to the pressure switch (Figure 9).
The connections on must be torqued to 17.7 Lbf-in (2 Nm).

Start-Up Procedures
CAUTION: Break-in period
Before initial use, open the ball valve and run the compressor without air tools attached and through open air line for 30
minutes to break-in pump parts.
Note: This electric model is equipped with a pressure switch that automatically turns the motor off when the tank pressure
reaches its present level. Once air pressure in the tank drops to a preset low level, the pressure switch automatically
turns the motor back on.
WARNING: Overheating
This compressor is equipped with “auto shut off”. However, failure to allow adequate cooling ventilation or a restriction in the
intake airflow may cause the machine to overheat.
WARNING: Inflatables/Low PSI tire
Never use compressor to inflate small low-pressure objects, i.e., balloons/inflatables, small or low volume PSI tires. It is easy
To over-pressurize them, causing them to rupture. Identify the inflation capacity of an object prior to filling it with air. Use a
gauge to check the pressure regularly when inflating anything.
Proper Air Hose and Tool Use
Pressure Control Related Devices
Never remove, adjust, bypass, change, modify or make substitutions for safety/relief valves, pressure switches or other
pressure control related devices. Pressurizing beyond the limits of the compressor could result in an explosion.
WARNING: Overpressurization hazard
NEVER over-pressurize the receiver tank or air tools beyond nameplate capacity. Exceeding the pressure rating could cause
them to explode or fly apart.
Compressor - Tool Requirements
Compressor and attachments must be sized properly for pressure and air volume.
Consider the maximum pressure requirements and air volume requirements of each. (The volume rating of your
compressor is listed in the “Specifications” section.)
CAUTION: Tool overpressure hazard
Do not operate this unit with any tool rated less than the maximum operating pressure of the unit (145 PSI) unless a
properly sized regulator limiting pressure is used before the tool.

Figure 11
1. Verify that the pressure switch is in the OFF position. (Figure 11)
2. Turn regulator counter clockwise to close, if installed.
3. Verify that the pressure gauge reads zero.
4. Open the ball valve so that air flow is permitted.
5. Turn the pressure switch to the AUTO position.
6. Adjust regulator to desired pressure, if installed.
7. Allow pressure in receiver tank to build.

Attaching/Disconnecting Air Hose and Tools
CAUTION: High pressure stream hazard
High-pressure air stream can pierce skin and underlying tissues, leading to serious injury and possible amputation. Such an
injection injury can result in blood poisoning and/or severe tissue damage. High-pressure air stream can also cause flying
debris and possible surface damage.
On a fixed line distribution system the flexible hosing and tools would typically be connected at a terminating point. In some
cases where a fixed system does not exist, the flexible hosing can be attached to the quick connect fitting on the main
compressor outlet or after the user installed regulator.
CAUTION: Air tools hazard
Do not attach air tools to open end of the hose until start-up is completed and the unit checks out
Quick Connect Procedure:
Keep finger off tool or activation switch untilready to use.
Pull quick connect collar back (Figure 12a).
Push hose or attachment firmly against stop.
Let go of collar (Figure 12a).
Pull and rotate slightly (hose or attachment)to assure a tight connection.
WARNING: Projectile hazard
Air tool or attachment can become a projectile and cause serious
personal injury or damage if not securely attached to the air hose.
Using Compressor for Spraying
Flammable Materials
Always follow precautions on container labels or MSDS’before spraying flammable materials, such as paint.
Moisture in Compressed Air
Moisture in supply air when compressed will form into droplets as it leaves air compressor pump and enters receiver
tank. When humidity is high or when a compressor is in continuous use for an extended period of time, a significant
amount of moisture will collect in the tank. Part of the moisture will be discharged in the outlet air.
When using a paint spray or sandblast gun, this water will be carried from the tank through the hose, and out of the gun
as droplets mixed with the spray material. If this is not acceptable for your application, an external air dryer must be
added to the system.
Shutdown
Procedure
When you are finished using the compressor:
1. Move the pressure switch to the OFF position.
2. Close the ball valve to stop airflow.
3. Unplug the power cord.
4. Operate tools briefly to release live pressure
5. Disconnect all tools.
6. Drain air receiver tank by pulling safety relief valve.
7. After all storage air is discharges, disconnect hoses and open the ball valve.
8. Once the tank pressure gauge registers under 10 PSI, open the drain valve on the bottom of the tank to drain condensation
moisture.

Immediately turn off the compressor if any of the following conditions arise during operation:
Excessive change in motor speed, slow or fast
Overheating
Excessive vibration
Unusual noise
Flame or smoke
Air leakage
Pull ring on safety valve to immediately relieve pressure.
WARNING: Shutdown hazards
Do not leave an operating machine unattended. Always shut the machine OFF and relieve the pressure before leaving the
machine. NEVER disconnect the high- pressure outlet hose from the unit while the tank and airline are pressurized. A
hazardous high pressure air stream will result as receiver tank is quickly emptied

WARNING: Maintenance hazards
ALWAYS disconnect, lock out and tag the main power supply and then release air pressure from the receiver tank before cleaning,
adjusting, or servicing the compressor. Make sure all guards and shields are replaced before re-starting.

Detailed Instructions –Maintenance & Repair
NOTICE
Dispose of used motor and pump oil in a manner that is compatible with the environment and in accordance with local, state,
and federal laws and regulations.
• Take used oil in a sealed container to your local recycling center or service station for reclamation.
• Do not throw it in the trash, pour it on the ground, or pour it down a drain.
No Modifications.
Never modify or alter the compressor in any way. Modifications can create serious safety hazards and will void the warranty.
Inspect Safety/Relief Valve
This valve should be inspected and tested on a weekly basis. The safety valve automatically releases air if the tank pressure
exceeds the preset maximum.
• Check the safety/relief valve by pulling the rings. It is spring loaded and should not be stuck but come out about ¼” and
then snap back into position when released.
• Replace safety/relief valves that do not operate freely with a valve of the same pressure rating.
WARNING: Safety/Relief valve hazards
If the safety/relief valve does not work properly, over- pressurization may occur causing air tank rupture or explosion.
Occasionally pull the ring on the safety valve to make sure the safety valve operates freely. If the valve is stuck or does not
operate smoothly, it must be replaced with a valve having the same pressure rating.
Inspect Air Filter
Inspect the compressor’s air filter on a weekly basis. A dirty air filter will not allow the air compressor to operate at full
capacity.
• Clean air filter if dirty and restricted air flow.
• Replace the air filter every 12 months or 1000 hours.
Note: Do not operate with the air filter removed.
MAINTENANCE & REPAIR

Keep Compressor Clean
Do not allow air intakes to become blocked. If dust or debris accumulates in the compressor, clean with a damp cloth or soft
bristle brush.
Note: Do not spray compressor with a garden hose or pressure washer. Water may enter the compressor and cause damage
to the motor and pump.
Inspect Compressor for Air Leaks
Inspect system for air leaks on a monthly basis. To test:
• Squirt soapy water around joints during compressor operation and watch for bubbles. Developing bubbles indicate
a leak is present.
• Tighten fittings, if necessary.
Change Pump Oil
WARNING: Burn hazard
Never open oil fill port while compressor is running. Hot oil can spray over face and body.
After the first 50 hours of use then every 3 months or 500 hours, change pump oil while crankcase is still warm. (See
“Appendix A: Lubricants”for suitable alternatives.)
1. Remove the oil fill and drain plugs. Collect the oil in a suitable container.
2. Replace the oil drain plug and refill compressor crankcase with clean oil.
3. Replace the oil fill plug.
4. Start the unit and run for several minutes. Shut down the air compressor
and recheck the oil level. If necessary, add more oil. (Figure 13)
Drain Receiver Tank and Inspect Tank
Drain water from the receiver tank daily. Water left in the tank can cause the tank to weaken and corrode, increasing the risk
of tank rupture. Badly rested receiver tanks must be replaced.
Recommends a tank inspection after every 2 years of service. See “Inspection of Unfired Pressure Vessels,”volumes 2-9,
August 2001, Bill McStraw (available on-line at NTIS).”
WARNING: Air tank hazards
Failure to replace a rusted air receiver tank will eventually result in tank rupture or explosion, which could cause substantial
property damage, severe personal injury, or death. Never modify or repair a tank. Obtain replacement from service center.
Check Drive Belt for Tension and Alignment
CAUTION: Pulley/sheave hazard
Improper pulley/sheave alignment and belt tension can result in motor overload, excessive vibration and premature belt
and/or bearing failure. To prevent this from happening, check the pulley/sheave alignment and belt tension on a regular
basis.
Belts will stretch from normal use. When properly adjusted, a 5 lb. force applied to the belt between the motor pulley and the
pump will deflect the belt about ½”.
To align and adjust drive belt tension:
1. Remove the belt guard cover.
2. Loosen the four fasteners securing the motor to the compressor unit.
3. Slide the motor to achieve proper belt tension. (Usually 1/8” to 1/4” is
sufficient.) The belt must be properly aligned before refastening the motor.
4. To align belt, lay a straight edge against the face of the compressor
sheave (flywheel) touching the rim at two places. (Figure 14)

5. Adjust the motor pulley by shifting the motor so that the belt runs
parallel to the straight edge.
6. If necessary, use a gear puller to move the motor pulley. Tighten
set screw after motor pulley is positioned
7. Check for proper belt tension. (Figure 15)
8. Tighten the four fasteners holding the motor to the top plate while
tension and alignment is maintained.
9. Attach the belt guard cover.
Keep Compressor Clean
Do not allow air intakes to become blocked. If dust or debris accumulates in the compressor, clean the compressor with a
damp cloth or soft bristle brush.
Note: Do not spray compressor with a garden hose or pressure washer. Water may enter the compressor and cause damage
to the engine and pump.
IMPORTANT
If a part needs replacement, only use parts that meet the manufacturer’s part number specifications. Replacement parts that
do not meet specifications may result in a safety hazard or poor operation of the compressor. Major service, including
installation or replacement of parts, should be made by a qualified electrical service technician.
