the pressure switch and OFF (0) to remove power at the end of each use.
DANGER: Risk of Shock. ALWAYS ensure the switch (E) is in the OFF (0) position and unit is unplugged before removing or replacing pressure switch cover.
PRESSURE SWITCH
The pressure switch (not shown) automatically starts the motor when the tank
pressure drops below the factory set cut-in pressure. It stops the motor when
the tank pressure reaches factory set cut-out pressure.
SAFETY VALVE
This valve (A) is designed to prevent system failures by relieving pressure
from the system when the compressed air reaches a predetermined level. The
valve is preset by the manufacturer and must not be removed or modified in any
way.
CHECK VALVE
When air compressor is operating, the check valve (B) is open, allowing
compressed air to enter the tank. When the air compressor reach-es cut-out
pressure, the check valve closes, allowing air pressure to remain inside the
tank.
AIR INTAKE FILTER
The filter (C) is designed to clean air entering the pump. To ensure the pump
continually receives a clean air supply, the filter must always be clean and
the filter intake must be free from obstructions.
TANK DRAIN VALVE
The drain valve (I) is located at the base of the tank and is used to drain
condensation at the end of each use. See Draining Tank under Maintenance.
TANK PRESSURE GAUGE
The tank pressure gauge (G) indicates the reserve air pressure in the tank.
REGULATOR
(Sold separately, not shown) An air pressure regulator or a separate air
transformer which combines the functions of air regulation and/ or moisture
and dirt removal is recommended for most applications. See Air Distribution
System paragraph under Installation.
DANGER : Risk of Bursting. Too much air pressure causes a hazardous risk of bursting. Check the manufacturer’s maximum pressure rating for air tools and accessories. The outlet pressure must never exceed the maximum pressure rating of the tools or accessories.
PUMP
The pump compresses air into the tank. Working air is not available until the
pump has raised the tank pressure above that required at the air outlet.
MOTOR OVERLOAD PROTECTOR
The motor has a thermal overload protector. If the motor over-heats for any
reason, the overload protector will shut off the mo-tor. The motor must be
allowed to cool down before restarting.
To restart:
- Set the Auto/Off switch to OFF (0) and unplug unit.
- Allow the motor to cool.
- Depress the red reset button (T) on the motor.

- NOTICE: Long lengths of electrical wiring could cause power loss to the motor.
- The air filter must be kept clear of obstructions which could reduce air flow to the air compressor.
HUMID AREAS
In frequently humid areas, moisture may form in the pump and produce sludge in
the oil, causing parts to wear out prematurely. Excessive moisture is
especially likely to occur if the unit is located in an unheated area that is
subject to large temperature changes. Two signs of excessive humidity are
external condensation on the pump when it cools down and a “milky” appear-ance
in air compressor oil. You may be able to prevent moisture from forming in the
pump by increasing ventilation or operating for longer intervals.
ANCHORING OF THE AIR COMPRESSOR
DANGER: Risk of bursting. Excessive vibration can weaken the tank and
cause an explosion. Air compressor must be properly mounted.
The air compressor MUST be bolted to a level, solid surface. Use 3/8″ lag
screws, vibration pads and anchors. If help is needed anchoring the air
compressor consult a licensed contractor.
- Place the air compressor on a level, solid surface. Make sure the surface is in good condition with no cracks or damage.
- Mark the surface using the holes in the air compressor feet as a template.
- Drill holes in the surface for the anchors. Install anchors.
- Line-up holes in surface with holes in air compressor feet.
- Place the vibration pads (not supplied) between the floor and air compressor feet, see Fig 15. If needed, use shims to level the unit.
- Place the 3/8″ lag screws through the air compressor feet, vibration pads and into the anchors.
- Torque 3/8″ lag screws to 7-10 ft.-lbs (9.5-13.5 Nm).

WARNING: Improper electrical installation of this product may void its warranty and your fire insurance. Have circuit wiring performed by qualified personnel such as a licensed electrician who is familiar with the national electrical code and any prevailing local electrical codes.
DANGER: Risk of electrical shock. Improper electrical grounding can result in electrical shock. The wiring should be done by a qualified electrician.
A qualified electrician needs to know the following before wiring:
- The amperage rating of the electrical box is adequate. Refer to the Specifications, for this information.
- The supply line has the same electrical characteristics (voltage, cycle, phase) as the motor. Refer to the motor nameplate for this information.
NOTICE: The wiring used must be rated for the motor nameplate voltage,
plus or minus 10%. Refer to local codes for recommended wire sizes, correct
wire size and maximum wire run. Undersized wire causes high amp draw and
overheating to the motor.
NOTICE: A circuit breaker is recommended. If the air compressor is
connected to a circuit protected by fuses, use only time delay fuses marked
“D” or “T”.
DANGER: Risk of electrical shock. Electrical wiring must be located away from hot surfaces such as manifold assembly, air compressor outlet tubes, heads or cylinders.
GROUNDING INSTRUCTIONS
-
DANGER: Risk of electrical shock. In the event of a short circuit, grounding reduces the risk of shock by providing an escape wire for the electric current. This air compressor must be properly grounded.
This product must be connected to a grounded, metallic, permanent wiring system, or an equipment-grounding terminal or lead on the product. -
DANGER: Risk of electrical shock. Improper grounding can result in electrical shock.
VOLTAGE AND CIRCUIT PROTECTION
Refer to the Voltage and Minimum Branch Circuit Requirements under
Specifications.
- Voltage supply to circuit must comply with the National Electrical Code.
- Circuit is not used to supply any other electrical needs.
MAIN POWER DISCONNECT SWITCH
Install a main power disconnect switch in the line from the panel to the air
compressor. The main power disconnect switch must be located near the air
compressor, for ease of use and safety. When turned OFF, the main power
disconnect switch shuts off all power to the air compressor. When turned ON,
the air compressor will start and stop automatically, controlled by the
pressure switch.
AIR DISTRIBUTION SYSTEM
DANGER: Risk of bursting. Do not use polymeric pipe not safety certified and
not marked for use with compressed air. Conventional plastic or PVC pipe is
not designed for use with compressed air regardless of its marked pressure
rating.
NOTICE: Compressed air from oil lubed air compressors will contain water condensation and oil mist. Several drains, traps and filters will be needed to supply air without water (including aerosols) or oil to spray equipment, air tools and accessories requiring filtered air. Always read the instructions for the air tools and accessories being used.
- Use pipe that is the same size as the tank outlet. Piping that is too small will restrict the flow of air.
- If piping is over 100′ (30.5 m) long, use the next larger size.
- Bury underground lines below the frost line and avoid pockets where condensation can gather and freeze. Apply pressure before underground lines are covered to make sure all pipe joints are free of leaks.
- A flexible coupling is recommended to be installed between the globe valve/air discharge outlet and main air distribution line to allow for vibration.
- A separate regulator is recommended to control the air pressure. Air pressure from the tank is usually too high for individual air driven tools.
- DO NOT install lubricators between the tank and any spray equipment, air tool or accessory requiring oil-free filtered air.
- Drain all traps, filters and dirt legs daily.

- DANGER: Risk of bursting. If the safety valve does not work properly, over-pressurization may occur, causing tank rupture or an explosion.
- WARNING: Risk from flying objects. Always wear certified safety equipment: ANSI Z87.1 eye protection (CAN/CSA Z94.3) with side shields.
- WARNING: Risk from noise. Use ear protection (ANSI S12.6 (S3.19) as air flow noise is loud when draining.
- Before starting air compressor, pull the ring on the safety valve (A) to make sure that the safety valve operates freely. If valve is stuck or does not operate smoothly, it must be replaced with the same type of valve.
CHECKING AIR FILTER
WARNING: Hot surfaces. Risk of burn. Tubes, pump head, and surround-ing
parts are very hot, do not touch (see the Hot Surfaces identified in Fig. 4).
Allow air compressor to cool prior to servicing.
A dirty air filter will not allow the air compressor to operate at full
capacity. Keep the air filter clean at all times.
- Ensure Auto/Off switch is in the OFF (0) Position.
- Allow unit to cool.
- Unsnap/Rotate the air filter cover to remove (S).
- Check the filter element. If it is dirty, blow compressed air through the filter element for 10-15 seconds or replace if needed. If the filter is filled with paint, replace it.
- Place element into housing and reattach the air filter cover.
WARNING: Risk of unsafe operation. Do not operate without air filter.
DRAINING TANK (Fig. 5)
- WARNING: Risk of unsafe operation. Tanks contain high pressure air. Keep face and other body parts away from outlet of drain. Use eye protection [ANSI Z87.1 (CAN/CSA Z94.3)] when draining as debris can be kicked up into face.
- WARNING: Risk from noise. Use ear protection (ANSI S12.6 (S3.19) as air flow noise is loud when draining.
- NOTICE: All compressed air systems generate condensation that accumulates in any drain point (e.g., tanks, filter, aftercoolers, dryers). This condensate contains lubricating
oil and/or substances which may be regulated and must be disposed of in accordance with local, state, and federal laws and regulations.
-
Set the Auto/Off switch to “OFF (0)”.
-
Pull ring on safety valve allowing air to bleed from the tank until tank pressure is approximately 20 PSI. Release safety valve ring.
-
Drain water from tank by opening drain valve (clockwise) on bottom of tank.
DANGER: Risk of bursting. Water will condense in the tank. If not drained, water will corrode and weaken the tank causing a risk of tank rupture.
NOTICE: Risk of property damage. Water from tank may contain
oil and rust which can cause stains. -
After the water has been drained, close the drain valve (counterclockwise). The air compressor can now be stored.
NOTICE: If drain valve is plugged, release all air pressure. The valve can then be removed, cleaned then reinstalled.
AIR COMPRESSOR PUMP OIL (FIG. 3)
- NOTICE: Risk of property damage. Use air compressor oil only. Multi-weight automotive engine oils like 10W30 should not be used in air compressors. They leave carbon deposits on critical components, thus reducing performance and air compressor life.
- NOTICE: Use full synthetic, non-detergent air compressor oil.
- NOTICE: Crankcase oil capacity is approximately 32 fluid ounces (946 ml).
CHECKING OIL
- The oil level should be to the middle of the sight glass (X).
- If needed, remove oil fill plug (Y) and slowly add oil until it reaches the middle of the sight glass.
CHANGING OIL
WARNING: Drain tank to release air pressure before removing the oil fill
plug or oil drain plug.
- Remove the oil fill plug (Y).
- Remove the oil drain plug (W) and drain oil into a suitable container.
- Replace the oil drain plug (W) and tighten securely.
- Slowly add air compressor oil until it reaches the middle of the sight glass (X).
- NOTICE: When filling the crankcase, the oil flows very slowly into the pump. If the oil is added too quickly, it will overflow and appear to be full.
- CAUTION: Overfilling with oil will cause premature pump failure. Do not overfill.
- Replace oil fill plug (Y) and tighten securely.
BELT REPLACEMENT
WARNING: This unit starts automatically. ALWAYS shut off and unplug the
air compressor, and bleed all pressure from the system before servicing the
air compressor, and when the air compressor is not in use. Do not use the unit
with the shrouds or belt guard removed. Serious injury could occur from
contact with moving parts. Hot surfaces. Risk of burn. Pump head, and
surrounding parts are very hot, do not touch (see the Hot Surfaces identified
in Fig. 4). Allow air compressor to cool prior to servicing.
