Power cord grips used in this product: Type”Y”.

Assembly design in this product causes insulation to be affected 

by liquid spills or splashing.

Before gaining access to terminals,

  all power circuits should be disconnected.

            We do not recommend using power

  cord extensions with compressors.  Using that type of

  extension cause power drops resulting in motor 

potency loss and overheating.  Instead of using an extension 

cord increase the compressor’s action scope connecting a 

longer hose into the outlet. Connect additional hose lengths 

as needed.

SPECIFIC SAFETY GUIDELINES.

           THERE IS IMMINENT HAZARD OF SEVERE 

INJURY OR DEATH. TO REDUCE RISK OF FIRE OR 

EXPLOSION NEVER SPRAY FLAMMABLE LIQUIDS IN 

ENCLOSED AREAS.

1.   It is normal for the pressurestat to produce sparks while 

operating.  Should sparks come into contact with gasoline 

fumes or other solvents they could be ignited causing fire 

or explosion.  Always operate the compressor in a 

well-ventilated area.  Do not smoke while spraying.  Do 

not spray where open fire is present.  Keep the compressor 

as far away as possible from the spraying area.

2.   Solvents like Trichloroethane and Methylene Chloride may 

present a chemical reaction with aluminum used in a 

paint-spraying gun, paint pumps, etc., and may cause 

explosion.  Should you be using these types of solvents 

use only stainless steel spraying equipment: it will not 

affect the air compressor but could affect the equipment 

being used. 

3.   Never inhale compressed air produced by the compressor.  

It is not suitable as breathing air.

               POTENTIAL HAZARD OF SEVERE  

INJURY OR DEATH.

1.  Do not carry out welding jobs in the compressor air tank. 

An extremely dangerous condition may be created.  If 

carrying out any welding job on the tank the warranty will 

be void.

2.   Never use an electric air compressor outdoors when is 

raining or in wet surfaces. Hazard of electrocution!

3.   This unit starts automatically.  Always turn off the 

compressor.  Remove the plug from the power outlet and 

purge all pressure remaining in the system before servicing 

or when the compressor is idle.

4.   Double-check both the maximum pressure specified by 

the manufacturer and the pneumatic accessories.  The 

compressor exit pressure should be regulated to never 

exceed the maximum specified pressure.

5.   Under the unit’s cover there is high temperature as well 

as moving parts.  To prevent from burns or other hazards 

do not operate if the cover is not in place.  Allow the 

compressor to cool down before handling and servicing.

6.   Double-check you read the labels on paints or toxic 

materials you will spray.  Follow all safety rules.  Use a 

breathing mask if there is possibility of inhaling the sprayed 

material.  Read the instructions and make sure it gives the 

adequate protection.

7.   When using the air compressor always wear safety glasses 

or goggles.  Never aim the spraying nozzle towards other 

people or any part of the body.

8.   By no means adjust the pressurestat or relief valve.  It will 

make the warranty void.  Those devices are factory 

pre-adjusted to the maximum pressure for this unit.

                 POTENTIAL DANGER OF MODERATE  

INJURY OR DAMAGE TO THE UNIT.

1.   Drain periodically the humidity from the tank. A clean and 

dry tank will prevent corrosion.

2.   Pull daily the pressure relief valve rung to assure the valve 

is working correctly.  It also removes any obstruction from 

the valve.

3.   Provide adequate surrounding ventilation space to cool 

down the compressor.   It should sit approximately at 12” 

from the nearest wall and in a well-ventilated are.

4.   Securely fasten the compressor and release the tank 

pressure before transporting.

5.   Protect both air hose and power cable against damage or 

punctures.  Inspect weekly to detect weak or worn points.  

Replace if necessary.

APLICATION

Compressors are widely used with different tools as well as 

pneumatic tools in communications, machinery manufacturing, 

medical and health applications, garment manufacturing, 

spinning and weaving, wheels manufacturing, gas filling and 

paint.

OPERATION, LUBRICATION AND MAINTENANCE

1.   Please read carefully all technical documents after opening 

the packaging box (including the operation instructions).  

Double-check all parts are present and verify the 

compressor is not damaged.

2.   Verify oil level through the indicator spyhole set in the 

compressor rear side.  Should the oil level do not reach the 

middle (red circle), fill the deposit with SAE-30 motor oil until 

getting the right level.  Connect the power cable and operate 

compressor unloaded to verify is working correctly. (See 

figure 1)

3.   Connect the pneumatic tools and start the compressor in 

order to use them. (Note: The compressor should start with 

no load pressure). (See figure 2)

4.   The compressor works with SAE-30 lubricating oil. Fill with 

oil before operating. While running the oil temperature should 

be below 158 ºF. (See figure 1)

5.   After 5 hours operation, change oil and remove the casing 

cap. Wipe the dirty oil and other debris. Then, set the casing 

cap back and restart the air compressor.

Change oil every 150 working hours.

6.   Clean filter regularly once a week. (See figure 1).
7.   After 16 hours of operation open the purge valve below the 

tank, drain water from tank.  Clean the tank every six months. 

(See figure 4).

8.   After each use disconnect and release air pressure from the 

tank. (See figure 3)

9.   Service normally.  Disassemble the compressor and clean 

all its parts using light oil.  Wipe dry all parts.  When 

assembling, apply grease in all parts that are in contact.  

Repair or replace worn parts if necessary.  Assemble and 

adjust back all the parts.

10. When the compressor will not be used for a long period of 

time clean and grease all air valves and contact surfaces.

• The compressor has a thermal switch (See figure 5) that prevents 

the motor from overheating. The motor shuts off when the switch 

is activated. To re-establish the motor follow the following steps:

1.- Press the switch to ensure that the compressor is off.
2.- Let the compressor cool down for at least 5 minutes.
3.- Press the thermal switch located on the side of the crankcase.
4.- Lift the switch to start the compressor.

source before servicing, compressor must be grounded, do not expose to rain, 

store indoors..

RISK OF FIRE OR EXPLOSION.

 Do no spray combustible/flammable liquid 

in a confined area, spray area must be well ventilated, do not smoke while 

spraying or spray where spark or flame is present, arcing parts keep compressor 

at least 20 feet away from spraying area and all explosive vapors.

RISK OF INJURY. 

 Do not direct air stream at body, use eye protection 

compressor starts automatically, moving parts, do not touch keep guards in 

place, compressor does not supply breathable air.

RISK OF BURSTING.

 Do not adjust regulator to result in output pressure 

greater than marked maximum pressure of attachment, if a regulator has not 

been installed, use only attachment rated at 1 379 kPa (200 PSI) or higher, do 

not weld on or repair tank-replace. 

DISCONNECT POWER SOURCE BEFORE CLEANING THE AIR FILTER.

If connected to a circuit protected by fuses, use time-delay fuse marked “D”

Complies with IEC.

To reduce the risk of electric shock, do not expose to rain, store indoors.
