Model G0954/55/56/57 (Mfd. Since 11/21)

WEARING PROPER APPAREL. Do not wear clothing, apparel or jewelry that can become entangled in moving parts. Always tie back or cover long hair. Wear non-slip footwear to reduce risk of slipping and losing control or accidentally contacting cutting tool or moving parts.

HAZARDOUS DUST. Dust created by machinery operations may cause cancer, birth defects, or long-term respiratory damage. Be aware of dust hazards associated with each workpiece material. Always wear a NIOSH-approved respirator to reduce your risk.

HEARING PROTECTION. Always wear hearing protection when operating or observing loud machinery. Extended exposure to this noise without hearing protection can cause permanent hearing loss.

REMOVE ADJUSTING TOOLS. Tools left on machinery can become dangerous projectiles upon startup. Never leave chuck keys, wrenches, or any other tools on machine. Always verify removal before starting!

USE CORRECT TOOL FOR THE JOB. Only use this tool for its intended purpose—do not force it or an attachment to do a job for which it was not designed. Never make unapproved modifications—modifying tool or using it differently than intended may result in malfunction or mechanical failure that can lead to personal injury or death!

AWKWARD POSITIONS. Keep proper footing and balance at all times when operating machine. Do not overreach! Avoid awkward hand positions that make workpiece control difficult or increase the risk of accidental injury.

CHILDREN & BYSTANDERS. Keep children and bystanders at a safe distance from the work area. Stop using machine if they become a distraction.

GUARDS & COVERS. Guards and covers reduce accidental contact with moving parts or flying debris. Make sure they are properly installed, undamaged, and working correctly BEFORE operating machine.

FORCING MACHINERY. Do not force machine. It will do the job safer and better at the rate for which it was designed.

NEVER STAND ON MACHINE. Serious injury may occur if machine is tipped or if the cutting tool is unintentionally contacted.

STABLE MACHINE. Unexpected movement during operation greatly increases risk of injury or loss of control. Before starting, verify machine is stable and mobile base (if used) is locked.

USE RECOMMENDED ACCESSORIES. Consult this owner’s manual or the manufacturer for recommended accessories. Using improper accessories will increase the risk of serious injury.

UNATTENDED OPERATION. To reduce the risk of accidental injury, turn machine OFF and ensure all moving parts completely stop before walking away. Never leave machine running while unattended.

Additional Safety for Air Compressors

Serious impact injury or death can occur from bursting tank, attachment tool, distribution line, or hose. Contact with hot compressor parts can result in burns. Operating this tool in an environment without proper ventilation or near combustible materials can lead to explosions or fires. Eyes and other soft tissues can be easily injured by air streams and debris projected by compressed air or attachment tools. To reduce the risk of these hazards, operator and bystanders MUST completely heed hazards and warnings below.

TANK INTEGRITY. Inspect tank, attachment

tools, pump, air lines, and valves for rust, damage, weakness, leaks, looseness, or excessive wear and repair/replace damaged components before operating. Replace a damaged tank immediately. DO NOT attempt to weld on, modify, or repair tank. Modifying tank can affect tank integrity and cause tank to burst.

ATTACHM ENT TO OLS. Always wear ANSIapproved eye protection and any additional personal protective equipment required by attachment tools. Pneumatic tools can propel objects and debris at high speeds or even explode. Never use damaged tools—they are even more likely to rupture. DO NOT exceed pressure ratings of tools or attachments as lines and seals may burst. Use proper air hose for tool and confirm air hose is long enough to reach work area without stretching. Do not carry attachment tool with hand on trigger to reduce risk of accidental firing. Always relieve outlet air line and hose before attaching/removing tools. Disconnect hose or tool from compressor when not in use.

MODIFICATIONS. DO NOT adjust or remove safety relief valve, pressure switch, or otherwise modify machine. Do not install shut-off valve between compressor pump and tank. Check, safety, and pressure valves are adjusted at factory for correct tolerances and abilities of compressor and are designed to keep tank and other components from bursting.

INTENDED USE. DO NOT use compressed air as breathable air supply and DO NOT aim compressed air or air tools at body parts or people. Compressed air can injure or propel debris into eyes or other soft tissues. Do not use compressor to inflate low-pressure objects that are likely to burst (like children’s toys).

DAILY MAINTENANCE. Test safety relief valve daily to dislodge any blockages and confirm it is working correctly. Drain moisture from tank daily to prevent internal corrosion that could weaken tank.

DISTRIBUTION LINES. Use only stainless steel, copper, or aluminum for air delivery/distribution lines. NEVER use PVC because it cannot withstand the pressure, heat, condensation, and oils of compressed air and may shatter, creating dangerous shrapnel.

VENTILATION. Only operate in well-ventilated environment that is less than 100°F and keep compressor at least 18 inches from nearest wall. DO NOT obstruct airflow to air filters and ventilation openings. Regularly check and change air filters to avoid buildup of impurities and reduce risk of fire.

COMBUSTION. Compressor motor, pressure switch, and some pneumatic attachment tools often produce sparks. Only operate compressor in area free of combustible materials to prevent fires and explosions. When spraying, locate air compressor at least 20 feet from spray area, do not smoke, and do not spray flammable material in confined area near flame/compressor. Turn compressor OFF when unattended. Motor could overheat and create fire hazard.

HOT PARTS. Discharge line and other compressor pump parts heat up during operation. Do not touch these parts during or immediately following operation to prevent burns.

MOVING AND SERVICING. Disconnect power, allow compressor to cool, bleed air from system, and disconnect attachment tools and hoses before moving or servicing to prevent impact injuries, soft tissue injuries, and burns.

SECTION 2: POWER SUPPLY

Before installing the machine, consider the availability and proximity of the required power supply circuit. If an existing circuit does not meet the requirements for this machine, a new circuit must be installed. To minimize the risk of electrocution, fire, or equipment damage, installation work and electrical wiring must be done by an electrician or qualified service personnel in accordance with all applicable codes and standards.

or equipment damage

not properly grounded

The full-load current rating is the amperage a machine draws at 100% of the rated output power. On machines with multiple motors, this is the amperage drawn by the largest motor or sum of all motors and electrical devices that might operate at one time during normal operations.

The full-load current is not the maximum amount of amps that the machine will draw. If the machine is overloaded, it will draw additional amps beyond the full-load rating.

If the machine is overloaded for a sufficient length of time, damage, overheating, or fire may result— especially if connected to an undersized circuit. To reduce the risk of these hazards, avoid overloading the machine during operation and make sure it is connected to a power supply circuit that meets the specified circuit requirements.

Note: Circuit requirements in this manual apply to a dedicated circuit—where only one machine will be running on the circuit at a time. If machine will be connected to a shared circuit where multiple machines may be running at the same time, consult an electrician or qualified service personnel to ensure circuit is properly sized for safe operation.

For your own safety and protection of

A power supply circuit includes all electrical equipment between the breaker box or fuse panel in the building and the machine. The power supply circuit used for this machine must be sized to safely handle the full-load current drawn from the machine for an extended period of time. (If this machine is connected to a circuit protected by fuses, use a time delay fuse marked D.)

This machine is prewired to operate on a power supply circuit that has a verified ground and meets the following requirements:

Since this machine must be permanently connected to the power supply, an extension cord cannot be used.

Connection Type

A permanently connected (hardwired) power supply is typically installed with wires running through mounted and secured conduit. A disconnecting means, such as a locking switch (see following figure), must be provided to allow the machine to be disconnected (isolated) from the power supply when required. This installation must be performed by an electrician in accordance with all applicable electrical codes and ordinances.

process. DO NOT connect to power until

In the event of a malfunction or breakdown, grounding provides a path of least resistance for electrical current to reduce the risk of electric shock. A permanently connected machine must be connected to a grounded metal permanent wiring system; or to a system having an equipmentgrounding conductor. All grounds must be verified and rated for the electrical requirements of the machine. Improper grounding can increase the risk of electric shock!

Anchoring to Floor

Lag shield anchors with lag screws (see below) are a popular way to anchor machinery to a concrete floor, because the anchors sit flush with the floor surface, making it easy to unbolt and move the machine later, if needed. However, anytime local codes apply, you MUST follow the anchoring methodology specified by the code.

Before the machine can be connected to the power source, an electrical circuit and connection device must be prepared per the POWER

SUPPLY

setup instructions in this manual must be complete to ensure that the machine has been assembled and installed properly. The disconnect switch installed by the electrician (as recommended) is the primary means for disconnecting or connecting the machine to the power source.

Power Connection

Anchoring machinery to the floor prevents tipping or shifting and reduces vibration that may occur during operation, resulting in a machine that runs slightly quieter and feels more solid. Since this machine is extremely top heavy, anchoring it to the floor will also prevent injury and property damage.

If the machine will be installed in a commercial or workplace setting, or if it is permanently connected (hardwired) to the power supply, local codes may also require that it be anchored to the floor.

Distribution System

Design

Once you know how large your system will be, and what components you will install, choose a material for the distribution lines. Stainless steel, copper, and aluminum can withstand the force and heat of compressed air.

When designing your air distribution system, consider how many and what types of tools you intend to use, and what requirements those tools will have (see Connecting Air Tools on Page 24). The length of hose you use to connect tools to the system may affect how far the system needs to reach (see Choosing Air Hoses on Page 24).

Determine what methods you will use to remove moisture, oil, and dirt from the compressor air (see Distribution System Components on Page 23).

Plan to add a regulator for each supply line, and determine if you will need to add a lubricator. Installing quick-connect couplers will allow you to easily connect and disconnect air tools.

The compressor must be anchored at least 18 inches away from the nearest wall and 20 inches away from any combustible spraying operations.

Air Supply Line

Air Flow

Shut-Off

Valve

Decide how you will route the distribution lines. Forcing air flow up, against gravity, after it leaves the compressor, will naturally prevent moisture from proceeding through the line and reaching your tool.

Build your system using your desired pipes, fittings, filters, drains, and regulators, then use a flexible conduit or coupling to connect your air compressor. This will decrease any structural pressure on the tank and distribution pipes that could stress and damage the components. The Model G0954/G0955/G0956/G0957 has a shutoff valve to stop the airflow when attaching tools or servicing individual components.

Further information about air distribution systems is out of the scope of this manual. Consult outside resources and books for more suggestions.

Distribution System

Components

Regulator (Optional)

The distribution system is what delivers the air from your compressor to the tool you wish to use. Air delivery components can be damaged if dirt, oil, or water enter the air supply line. An air distribution system allows you to clean the air, remove moisture and heat, and regulate the pressure, all after the air leaves the compressor tank and before it enters the air tool.

Air Dryer

Before the air reaches an air tool, it must be dried by some method or another. One option is to install a moisture trap, which provides a place for moisture to collect where it can be easily drained (see "Drain Leg" in Figure 23 on Page 22 for an example).

Another option is to install a filter (see Figure

24). The filter can be cleaned and replaced, while any accumulated moisture is drained from a drain valve. Many of these can filter dirt, oil, and moisture at the same time.

Air In Air Out

Filter

Element

Drain Valve

Figure 25. Example of an air filter.

Regulator

A regulator (see Figure 26) is what adjusts the air supply line to your desired operating pressure. The operating pressure should always be equal to or less than the pressure that your air tool is rated for. An air tool recommended for 70 PSI should never be connected to a hose or system set to higher than that operating pressure, as the tool or valves could burst. A regulator allows tools with a lower rating than the system to still be attached, because the line can be adjusted to a safe level.

The last option is to install an actual air dryer. These are better suited for large industrial applications.

Air Filter

Ensuring clean air reaches your air tools will also extend tool life. If your method of moisture removal does not also filter out oil, dirt, and debris, we recommend also adding an in-line air filter (see Figure 25).

Lubricator

After water, debris, and oil from the compressor and environment have been removed, some air tools require lubrication be added back into the system to perform their job properly. Air line oil can be added directly to the tool before and during use, or an in-line lubricator can be added to the air supply line so oil is added automatically. Only use a lubricator for tools that require it. Adding lubrication, for instance, to a paint sprayer can contaminate the tool and paint and prevent a proper application.

Choosing Air Hoses

There are many options when it comes to hoses. The most important aspects for an air compressor are going to be length, diameter, and fittings. The material of the hose is also an important consideration, but this will depend more on your application and preference.

Length

Consider your applications before deciding on a hose length. Longer hoses, or hose connections to extend hose length, can increase your mobility, but will probably result in some pressure loss.

If your work area will be small, you may be able to use a shorter hose without stretching the hose. Never put any unnecessary stress on the hose, valves, fittings, or air delivery system.

An air compressor becomes very hot during operation, and the pressure switch and motor often produce sparks. Some applications, like spraying or sanding, involve flammable material that create a fire or combustion hazard when they are performed too close to a compressor. The hose length must allow for the air compressor to remain at least 20 feet away from the operation.

Fittings

Many hoses come with fittings installed. The simplest option is to find a hose with two fittings: one that matches the air line output port, and one that matches your intended attachment tool. If the hose does not match the port, a coupler may be needed.

You will need to determine the size of the fittings and whether they are male or female (see Figure 28). A male fitting can only attach to a female fitting, and vice versa. There are also a number of coupler/plug styles on the market, so be sure the two match or you will likely not have an airtight connection.

Male

Coupler

Diameter

A larger inner diameter will allow for higher airflow delivery. Refer to Airflow Delivery (CFM) for more information. The higher CFM a tool requires, the larger the inner diameter of the hose will need to be (see Figure 27).

Connecting Air Tools

There are various air tools that can be connected to your air compressor by means of the air distribution system, and the setup will vary little across tools, but there are a couple things to keep in mind before connecting a tool or hose.

Airflow Delivery (CFM)

The first consideration when choosing an air tool is whether or not the air delivery is compatible with your compressor. Smaller compressors, capable of less than 5 CFM, only supply enough pressure for smaller air tools like nailers, staplers, chippers, chisels, grinders, sanders, tire inflators, and paint sprayers. Air hammers, impact wrenches, impact hammers, and blow guns will probably require a larger compressor capable of 10-110 CFM.

-24-

Model G0954/55/56/57 (Mfd. Since 11/21)

Duty Cycle

The duty cycle of your compressor will also have an effect on how efficient the airflow delivery is. Refer to Figure 29 for some common duty cycles and what they mean.

Compressor can be used for up to half

50/50

60/40

75/25

100

Compressing air produces a lot of heat, so the pump and motor require some resting time in order to cool down. The "cycle" of an air compressor refers to how long it takes for the compressor to be used and subsequently cooled. The duty cycle dictates what percentage of the cycle you can spend using air before it must rest.

of its cycle (spends same amount of time resting as it does working).

Compressor can be used for up to 60% of its cycle; spends 40% of time resting.

Compressor can be used for up to 75% of its cycle; spends 25% of time resting.

Compressor can be used for up to 85% of its cycle; spends 15% of time resting.

Compressor does not need to rest. Engine/motor has a cooling component allowing for constant air delivery.

Figure 29. Common duty cycles.

Connecting Air Tool

Use the following steps as a guide for attaching an air tool. As there are a wide variety of tool and hose options, your connections may differ slightly from this simple outline.

Always wear personal protective equipment required by air tool you are using. Pneumatic grinders, sanders, paint sprayers, etc., require respirator to protect against longterm respiratory damage. Prolonged exposure to loud tools can result in hearing loss without the use of hearing protection.

To connect air tool:

Adjust in-line regulator in air supply line to 0

PSI.

Insert air hose male plug into quick-connect

coupler.

Connect other end of hose to air tool.

Note: Refer to air tool instructions for speci-

fications, method of connection, and proper use of tool.

Checking for Leaks

Air leaks will cause low air output and increase the time the compressor must run. Use the following method to check the valves and fittings on your compressor and air delivery system.

— If V-belt is in good condition and there is

⁄4" of deflection, belt does not need to be

adjusted or replaced. Proceed to Step 7.

— If V-belt is cracked, torn, excessively worn,

damaged, or there is not 1⁄4" of deflection, proceed to Step 4.

Loosen (4) hex nuts on hex bolts shown in

Adjusting Cut-In/

Cut-Out Settings

The pressure switch ensures the compressor will turn ON when the tank pressure drops to the cutin pressure, and will turn OFF when the pressure cut-out is reached. Should the pressure switch fail to turn OFF the machine, the safety relief valve will open shortly after the pressure exceeds the cut-out pressure and prevent over-pressurization.

Cut-in and cut-out settings have been factory set at proper PSI range. Only adjust pressure switch settings if compressor is cutting-in or cutting-out at incorrect pressures. Tank could burst if filled with more pressure than it is designed for.

Eye injury hazard! Always wear safety glasses when handling pressurized air system.

Adjusting Cut-In/Cut-Out Settings

If the minimum and maximum tank pressure settings both have to be raised or lowered at the same time, then follow these steps.

Releasing air through safety relief valve can be extremely loud. Protect hearing with ANSI-approved hearing protection while performing following step.

SHOCK HAZARD. Working on wiring that is con-

nected to a power source is extremely dangerous. Touching electrified parts will result in personal injury including but not limited to severe burns, electrocution, or death. Disconnect the power from the machine before servicing electrical components!

MODIFICATIONS. Modifying the wiring beyond what is shown in the diagram may lead to unpredictable results, including serious injury or fire. This includes the installation of unapproved aftermarket parts.

WIRE CONNECTIONS. All connections must be tight to prevent wires from loosening during machine operation. Double-check all wires disconnected or connected during any wiring task to ensure tight connections.

CIRCUIT REQUIREMENTS. You MUST follow the requirements at the beginning of this manual when connecting your machine to a power source.

WIRE/COMPONENT DAMAGE. Damaged wires or components increase the risk of serious personal injury, fire, or machine damage. If you notice that any wires or components are damaged while performing a wiring task, replace those wires or components.

MOTOR WIRING. The motor wiring shown in these diagrams is current at the time of printing but may not match your machine. If you find this to be the case, use the wiring diagram inside the motor junction box.

CAPACITORS/INVERTERS. Some capacitors and power inverters store an electrical charge for up to 10 minutes after being disconnected from the power source. To reduce the risk of being shocked, wait at least this long before working on capacitors.
