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

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 TOO LS. 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
may occur if machine is
not properly grounded
and connected to power
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.
For your own safety and protection of
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.
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.)

Improper connection of the equipment-grounding
wire can result in a risk of electric shock. The
wire with green insulation (with or without yellow
stripes) is the equipment-grounding wire. If repair
or replacement of the power cord or plug is necessary, do not connect the equipment-grounding
wire to a live (current carrying) terminal.
Check with a qualified electrician or service personnel if you do not understand these grounding
requirements, or if you are in doubt about whether
the tool is properly grounded. If you ever notice
that a cord or plug is damaged or worn, disconnect it from power, and immediately replace it with
a new one.
We do not recommend using an extension cord
with this machine.
cord, only use it if absolutely necessary and only
on a temporary basis.
Extension cords cause voltage drop, which can
damage electrical components and shorten motor
life. Voltage drop increases as the extension cord
size gets longer and the gauge size gets smaller
(higher gauge numbers indicate smaller sizes).
Any extension cord used with this machine must
be in good condition and contain a ground wire
and matching plug/receptacle. Additionally, it must
meet the following size requirements:
Grounding & Plug Requirements

Choosing Air Hose
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 having to move the
compressor or stretch the hose. Never pull the
hose to move the compressor or put any unnecessary stress on the hose, valves, fittings, or tank.
Fittings
Many hoses come with fittings installed. The simplest option is to find a hose with two fittings: one
that matches the compressor 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 15). 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.
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.
Diameter
A larger inner diameter will allow for high airflow
delivery. Refer to Airflow Delivery (CFM) on
Page 19 for more information. The higher CFM a
tool requires, the larger the inner diameter of the
hose will need to be (see Figure 14).

Connecting Air Tool
There are various air tools that can be connected
to your air compressor by means of an air hose,
and the setup will vary little across tools, but there
are a couple things to keep in mind before connecting a tool or hose.
2
Operating Pressure (Pounds/Inch
Your second consideration should be the recommended or required operating pressure of your
tool. 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.
)
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.
Duty Cycle
The duty cycle of your compressor will also have
an effect on how efficient the airflow delivery is.
Refer to Figure 17 for some common duty cycles
and what they mean.
Compressor can be used for up to half
50/50
60/40
75/25
85/15
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 17. Common duty cycles.
The Model T32337 has a regulator and pressure
gauge for controlling and observing your line pressure, making it require very little setup.
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 very simple outline.
Items Needed Qty
Air Tool (Rated for 90 PSI or Less) ................... 1
Air Hose
Additional Connection Fittings
Always wear personal protective equipment
required by air tool you are using. Pneumatic
grinders, sanders, paint sprayers, etc.,
require a respirator to protect against
long-term respiratory damage. Prolonged
exposure to tools with high sound ratings
can result in hearing loss without the use of
hearing protection.

Adjusting Cut-In/
Cut-Out Settings
The pressure switch ensures the compressor will
turn ON when the tank pressure drops to approximately 120 PSI (the cut-in pressure), and will turn
OFF when the tank pressure reaches 150 PSI (the
cut-out pressure). Should the pressure switch fail
to turn OFF the machine, the safety relief valve
will open shortly after the pressure exceeds 150
PSI and prevent over-pressurization.
