Inspect for Damage
Before using the air compressor, make sure the air tank is not
damaged, inspect all parts for damage, and check that all
pipes are firmly connected.
Do not use the air compressor if any damage is found. If
damaged, have an authorized service center inspect and test
the air compressor to ensure that it is working properly.
Save Packaging
IMPORTANT: Save all outside packaging in case you ever
need to return the product for service or repair.
Compressor Location
Use on Flat Surface
For proper operation, the air compressor must be placed on a
flat surface with an incline no greater than 15 degrees.
Maintain a Clear Area
It is very important that the air compressor is positioned so
that there is adequate airflow around the machine. There
must be at least 2 feet of obstacle-free space surrounding
and above the air compressor.
Use in Areas with Clean Air
For proper operation and to maximize the longevity of the
air compressor, it is very important that the air drawn into
the air compressor is clean. The air compressor should not
be used in areas where dust or particulates are in the air.
This will damage the motor and impair proper operation.
IMPORTANT: Always use the air filter, properly installed.

Electrical Power
Electrical Power Requirements
Before using the air compressor, refer to the serial label for
voltage and amperage requirements. Ensure there is a sufficient
electrical supply for supporting the motor's requirements.
Use a dedicated 15 Amp Circuit or a 5500 Watt (running)
Generator
Low voltage and/or an overload circuit can cause the
motor's overload protection system circuit breaker to trip.
Electrical Extension Cords
Inspect all electrical extension cords to ensure that they are
free of damage. When using an extension cord, use a heavy-
duty cord that is no more than 25 feet long and at least 14
gauge. Use only a 3-wire extension cord that has a 3-blade
grounding plug.
OPERATING THE AIR
COMPRESSOR
Save this manual for future reference.
Introduction
This air compressor features a compact structure, stable
performance, a high airflow rate, easy operation and
maintenance. Because the air compressor produces no oil in
the airflow, it can be used as an independent air supply
machine for situations in which oil in the airflow is an issue.
The motor directly drives the pistons and is able to function
without lubrication for a long period of time.
Assembly
1.
Connect an air supply hose [not supplied; featuring an
Industrial
Male
(1/4” NPT) adapter/couple (pictured below)], to the
Industrial Female (1/4” NPT) push-to-connect quick coupler on
air compressor. Also see page 12.
2. Connect 8mm tubing to Auto Drain Valve port located
at bottom of unit (press fit).
3. Ensure that the power supply you are going to use is
operating normally. 110 Volts 60 Hertz 15 Amp Outlet.
4. Insert the power supply cord into the power supply socket.

Test Run
Before using the air compressor for the first time, complete a
test run as follows:
1. Plug the power supply cord into a 110 volt 60hz power
supply socket.
2. PRESS & HOLD the SMART switch OK button for 4
seconds to turn ON air compressor.
3. Motor/pump should start.
4. Pressure will slowly rise as pressure increases inside the
air tank. When the pressure reaches 120 PSI (+/- 5 PSI),
the Smart pressure switch will automatically turn the
motor/pump power off. This indicates the compressor is
working normally.
NOTE: Working Pressure 90-120 PSI (+/-5 PSI).
Adjustable up to 105 PSI Kick-On; 130 PSI Kick-Off
maximum. Refer to Smart Controller Manual to adjust.
5.
Unplug the power supply cord and release the air in the
air tank by either of the following methods:
a. Pull on Safety Relief Valve ring to release air from air
tank. Suggested for initial testing or emergencieonly.
b. Expel air from compressor using connected Air Hose
Gun/Tool (i.e. CAT-376 item; not supplied). This is
the recommended discharge method for all regular &
daily compressor operations. See page 12.
Note: If there is an air leak from the compressor the
pressure in the air tank decreases, the Smart Controller
(pressure switch) resets and the motor automatically turns
back on.
If compressor fails to start or you detect an air leakage,
AIR COMPRESSOR
12
Customer Support: 1-866-409-4581
deactivate the air compressor and release the air from
the tank (if under pressure) – see Steps 2 & 5 above.
Unplug the power supply cord and contact Customer
Support for Assistance.
DAILY OPERATION
Starting the compressor:
1. PRESS & HOLD the SMART switch OK button for 4 seconds to turn OFF air compressor.
2. Attach an air hose gun or tool
(i.e. CAT-376 item; not supplied)

Turn the pressure up until the desired pressure is reached.
9. Operate air tool normally.
NOTE: Working Pressure 90-120 PSI (+/-5 PSI).
Adjustable up to 105 PSI Kick-On; 130 PSI Kick-Off
maximum.
Shutting down the compressor:
1. PRESS & HOLD the SMART switch OK button for 4 seconds to turn compressor OFF.
2. Unplug the power supply cord.

MAINTENANCE
Automatic Drain Tank Operation
The California Air Tools EZ-1 Automatic Drain Valve has been
designed to eliminate water by manually draining your air
compressor air tank on a regular basis. Attach 8mm drain tube
and route into container capable of holding water. Automatic
draining occurs under either of the following scenarios:
1. Opens for 3 seconds, and then closes, when air
compressor is first turned on.
2. Opens for 3 seconds, and then closes, after the
motor/pumps run continuously for 2 minutes.
.
NOTE: There is a manual drain bypass port which permits
manual removal of water from the tank. This port also allows
cleaning of the internal strainer should the Auto drain stop
ejecting water due to particulate clogging. CAUTION: Do not
open while tank has air pressure!
Cleaning or Changing the Air Filter
The air filter is designed to reduce noise and help prevent
particulates in the air from entering and damaging the air
compressor.
After being used for a period of time, the air filter will become
clogged. This will reduce the air intake capabilities of the air
compressor, reducing performance. Therefore, the air filter(s)
must be cleaned or replaced regularly.
1. Open the lid on the air filter, then remove the air filter element.
2. To clean the element blow off or brush off the dirt and dust.
3. If clogged, replace with a new air filter.
Testing for Leaks
Make sure all connections are tight. Do not overtighten.
A small leak in any hose or pipe connection will reduce the air
compressor's performance.
To test for small leaks, spray a small amount of soapy water on
the area suspected of leaking. If the soap bubbles, replace the
broken part.
Cleaning
Clean items with a soft brush, or wipe with a moistened cloth
using a biodegradable solvent.
Do not use flammable liquids such as gasoline or alcohol. Always
keep parts clean from dirt and dust for better performance.
SMART Controller Features
MDR2i OLED Smart Pressure Switch for remote monitoring and
control. Refer to MDR 2i Smart Controller Manual.

TROUBLESHOOTING
PROBLEM
POSSIBLE CAUSE
POSSIBLE SOLUTIONS
Pressure drop in the tank.
Air leaks at connections.
Let the compressor build pressure in the tank, to
the maximum pressure if possible. Brush soapy
water on air connections and look carefully for air
bubbles. Tighten leaky connections. If the
problem persists, contact the seller for further
advice.
The unloader valve leaks when
the compressor is idle.
Unloader valve seal is defective.
Let the air in the air tank flow out until all the
pressure is released. Then remove the unloader
valve plug and clean the valve seal. If necessary,
replace the seal and then reinstall all
components.
The compressor stopped and
does not start.
The thermal protector turned on
because the motor is overheating.
Check that the main voltage corresponds to the
air compressor specifications. An extension cord
that is too thin or too long can cause a voltage
drop and cause the motor to overheat.
Excessive use (over 1 hour continuous use)
can cause the motor to overheat
Allow the motor to cool down.
Motor windings are burned out.
Contact Customer Support.
