Safety Advice
DANGER!
1. RISK OF FIRE OR EXPLOSION. Do not spray a flammable or combustible liquid or paint near
sparks, flames, pilot lights or in a confined area. The spray area must be well-ventilated. Keep
compressor at least 20’ (6 m) away from spray area. Do not carry and operate the compressor or
any other electrical device near the spray area. Never smoke when spraying. Use a minimum of
25’ (7.6 m) of hose to connect a spray gun to the compressor.
2. RISK OF ELECTRIC SHOCK. Do not expose to rain. Store indoors. Hazardous voltage. Disconnect
from power source before servicing. Compressor must be grounded. Do not use grounding
adaptors.
3. RISK OF BURSTING. Make sure the regulator is adjusted so that the compressor outlet pressure is
set lower than the maximum operating pressure of the spray gun or tool. Before starting the
compressor, pull the ring on the safety valve to make sure the valve moves freely (see diagram on
page 17). Drain water from tank after each use. Do not weld or repair tank.

4. RISK OF PERSONAL INJURY. Never spray compressed air or material at self or others.
5. RISK OF BURSTING. Check the maximum pressure rating in the manual or identification label. The
compressor outlet pressure must be regulated so that it does not exceed the maximum pressure
rating. Relieve all pressure in the hose before removing or attaching accessories.
6. RISK OF BURSTING. Do not adjust the pressure switch or safety valve for any reason. They have
been preset at the factory for this compressor’s maximum pressure. Tampering with the pressure
switch or the safety valve may cause personal injury or property damage.
7. RISK OF BURNS. The pump and the manifold generate high temperatures. In order to avoid burns
or other injuries, do not touch the pump, the manifold or the transfer tube while the compressor is
running. Allow the parts to cool down before handling or servicing. Keep children away from the
compressor at all times.
8. RISK TO BREATHING. Be certain to read all labels when you are spraying paints or toxic materials,
and follow all safety instructions. Use a respirator mask if there is a chance of inhaling anything you
are spraying. Also, NEVER directly inhale the air produced by a compressor.
9. RISK OF EYE INJURY. Wear ANSI Z87.1 approved safety goggles when using an air compressor. Do
not point any nozzle or sprayer toward a person or any part of the body. Serious injury may occur if
the spray penetrates the skin.
WARNING!
1. Pull the pressure safety valve ring every day in order to ensure that the valve is
functioning properly.
2. The compressor must be located in a well-ventilated area for cooling, and
must be a minimum of 12” (31 cm) away from the nearest wall.
3. Protect the air hose and the power cord from damage and puncture. Inspect them for weak or worn spots every
week, and replace them if necessary.
4. Always wear hearing protection when using an air compressor. Failure to do so may result in hearing loss.
5. Do not carry the compressor while it is running.
6. Do not operate the compressor if it is not in a stable position.
7. Do not operate the compressor on a rooftop or an elevated position that could allow the unit to fall or be tipped
over.
8. Always replace a damaged gauge before operating the unit again.
Extension cords
As the distance from the supply outlet increases, you must use a heavier gauge extension cord. Using extension
cords with inadequately sized wire causes a serious drip in voltage, resulting in loss of power and possible product
damage. Refer to the table here to determine the required minimum wire size.

7. Plug in the power cord (K).
CAUTION! Use a dedicated circuit.
For best performance and reliable starting, the air compressor should be plugged into a dedicated
circuit, as close as possible to the fuse box or circuit breaker.
The compressor will use the full capacity of a typical 15 A household circuit. If any other electrical
devices are drawing from the compressor’s circuit, the air compressor may fail to start. Low voltage or
an overloaded circuit can result in sluggish starting that causes the motor overload protection system or
circuit breaker to trip, especially in cold conditions.
NOTE: A circuit breaker is recommended. If the air compressor is connected to a circuit protected by
a fuse, use dual element time delay fuses (type “T” only).
8. Set the pressure switch (C) to the ON position. The compressor will start. Run the compressor for 30 minutes.
If it fails, turn it off immediately and call the toll-free helpline at: 1-888-942-6686. Please note that breaking-
in the unit is only required prior to first use.

ITEM DESCRIPTION / REASON SERVICE
INTERVAL
Drain the
tank
Through normal operation of your air compressor, condensation water will accumulate
in the tank. To prevent corrosion of the tank from the inside, condensation must be
drained at the end of every workday. Be sure to wear protective goggles. Relieve the
air pressure in the system and open the drain valve on the bottom of the tank to drain.
In cold conditions, it is especially important to drain the tank after each use to reduce
the chance of problems resulting from the freezing of condensation water.
NOTE: Refer to To drain tank, page 19.
Daily
Check
the oil
Check the oil level in the pump through the oil sight glass. The pump oil level must be
within the red circle. Do not overfill or underfill. Daily
Check
the valve
Pull/activate the safety valve daily to ensure that it is operating properly and to clear
the valve of any possible obstructions. Daily
Clean the
air filter
A dirty air filter will reduce air compressor performance and life. To avoid
contaminating the pump, the filter should be cleaned frequently and replaced on
a regular basis. Clean the foam filter by immersing it in warm, soapy water. Dry
thoroughly after.
Weekly
Test for
leaks
Check that all connections are tight. Small leaks in the tank, hoses, connections or
transfer tubes will substantially reduce the air compressor and tool performance.
Spray a small amount of soapy water around the area of suspected leaks with a spray
bottle. If bubbles appear, repair, replace or re-seal the faulty component. Do not over
tighten any connections.
