UPON DELIVERY
1. Carefully remove all packaging material.
2. Inspect the equipment and all parts for any signs of concealed shipment or storage damages.
3. Remember to report any shipping damage to the carrier and make a notion on the delivery receipt.
IMPORTANT SAFETY INSTRUCTIONS
u· Read all warning labels and the operation man-
ual and be thorough on all aspects of the equip-
ment prior to operations.
·Always use proper eyeware and hearing pro-
tection when operating this equipment.
·Before use, on a regular basis check the com-
pressor and all of its components for any dam-
ages and repair or replace all defective or dam-
aged parts.
·Keep hands and all body parts away from the
equipment at all times (Never operate without
the belt guards).
·Maintain a clean work area free from spills,
dampness and any other source of contamina-
tion.
·Make sure this equipment is operated by pro-
fessional personnel only. Keep visitors and
especially children away from work area.
·Electric shock hazard:
Never use the compressor without connection
to a properly grounded outlet with the specified
voltage and fuse protection.
Do not use the compressor in a wet or explo-
sive environment.
Never attempt maintenance or adjustment with
the power connected or the equipment in oper-
ation.
·Tank safety valve:
This valve is factory installed to prevent the air
receiver from damage should a malfunction
occur in the compressor pump.
It is factory set a specific limit for your particu-
lar model and adjustment, and should never
be tampered with. Adjustment by user will auto-
matically void the warranty.
·Pressure switch:
The air pressure switch is set at the factory for
optimum performance of your equipment.
Never bypass or remove this switch, as serious
personal injury or equipment damage could
result from too high pressure.
·Motor and compressor pump:
Air compressor gets hot while in operation.
Never touch the motor, discharge tubing, or
compressor pump while in operation.
The compressor operates automatically while
the power is connected.
Never attempt any adjustment with power on.
Never operate the compressor with the belt
guard removed.
·Compressed air caution:
Compressed air from the unit may contain car-
bon monoxide. Air produced is not suitable for
breathing purposes.
Always use a respirator when spraying paint or
chemicals.
Always wear safety glasses or goggles when
spraying air.
·Air receiver:
Over pressurizing the air receiver could cause
an explosion or rupture. To protect from over
pressurizing, a factory preset safety valve is
included. DO NOT REMOVE, MAKE ADJUST-
MENT OR SUBSTITUTIONS FOR THIS
VALVE.
Occasionally pull the ring on the valve to make sure
that the valve operates freely. If the valve does not
operate freely, it must be replaced. Never weld to, drill
into or change the air receiver in any way.
Changing or tampering with any of the above men-
tioned conditions may result in voiding of the manufac-
turer's warranty. Be advised that any replacement parts
should be purchased with the same specifications as
the original equipment. Please contact your authorized
dealer for replacement parts or specifications.

ASSEMBLY INSTRUCTION
There is no assembly required. This compressor is completely pre-assembled at the factory.
Installation and Location:
Locate the compressor in a clean, dry and well ventilated area. The compressor should be located 12” to 18” from a
wall or any other obstruction that would interfere with the air flow through the fanbladed belt-wheel. Place the com-
pressor on a firm, level surface. The compressor is designed with heat dissipation fins which allow for proper cooling.
Keep the fins and other parts that collect dust and dirt clean. A clean compressor runs cooler and provides longer
service. Do not place rags, containers or other materials on top of the compressor which would obstruct ventilation
openings for proper compressor operating temperature.
For Vertical Type Only: For permanent installation, the compressor should be bolted to the floor through holes pro-
vided in the compressor feet. Shims must be used to level the compressor before bolting it to the floor. Severe vibra-
tion will result when the compressor is bolted down tightly and the feet are not level. This can lead to welds cracking
or fatigue failure of the air receiver.

BELT ADJUSTMENT:
Install the triangular belt and adjust it so when pres-
sure is applied onto center, there should be 1/2”
(approx.) slack. See sketch
Note: If the belt is installed too tightly, overloading of
the motor will occur. This will cause the motor to
overheat. If the belt is installed too loosely it will slip
and unstable operation and vibration will occur.
Caution: The rotating direction for the flywheel must
follow the arrow shown on the beltguard.
OPERATION INSTRUCTIONS
GENERAL DESCRIPTION OF OPERATION:
To compress air, the pistons move up and down in the
cylinder. On the down stroke air is drawn in through the
inlet valve. The discharge valve remains closed. On the
upstroke of the piston, air is compressed. The inlet air
closes and compressed air is forced out through the dis-
charged valve, through the check valve into air receiver.
Working air is not available until the compressor has
raised the air receiver above that required at the air
service connection. The air inlet filter openings must be
kept clear of obstructions, which could reduce air deliv-
ery of the compressor.
Depending on the CFM requirements of the tools used,
your new air compressor can be used for operating paint
sprayers, air tools, grease guns, air brushes, caulking
guns, sandblasters, inflating tires and inflatable toys,
spraying weed killer and insecticides, etc. An air pres-
sure regulator is usually necessary for most of these
applications.
IT IS STRONGLY ADVISED, BEFORE OPERATING THE COMPRESSOR THE FOLLOWING POINTS ARE
CAREFULLY CHECKED. (Daily)
1. Check to see that all nuts and bolts are snug.
2. Check to see if the belt is installed properly, with proper tension.
3. Check if the oil level is full.
4. Check if the compressor is fixed on a strong, stable level base.
5. Check if the oil breather is clean.
6. If the air filter is dirty it should be replaced or cleaned.
7. Check if the flywheel can be turned easily and smoothly.

INITIAL START-UP PROCEDURE:
Open the air receiver service valve to permit air to escape, preventing air pressure build-up in the air receiver.
Plug power supply cord into correct power source.
Close air receiver service valve. Your compressor is now ready for operations.
Run the compressor for a minimum of twenty (20) minutes in this no-load position to lubricate the bearings and
pistons.
MAINTENANCE
Before doing any maintenance or adjustments to your air compressor please ensure you have discon-
nected electrical power and drained the tank of pressure.
1. DAILY OR BEFORE EACH USE:
Check oil level.
Drain condensation from tank.
Check for any unusual noise or vibration.
Be sure all nuts and bolts are tight.
2. WEEKLY:
Clean air filter by opening air filter cap, remov-
ing the filter element and cleaning it thoroughly
with soap and water. Rinse thoroughly and
allow to dry completely before assembly. Old fil
ter should be replaced.
Clean breather hole on oil check dipstick.
3. MONTHLY:
Adjust belt tension if needed and replace belt
if worn.
Inspect air system for leaks by applying soap
to all joints. Tighten those joints if leakages are
observed.
4. 250 HOURS OR SIX (06) MONTHS (Which
ever comes first):
Change compressor oil.
Replace often if compressor is used near paint
spraying operations or in dusty environment.
COMPRESSOR LUBRICATION:
Note: Do not add or change oil while the compressor is
in operation. Use only the recommended SAE 20 or 30
weight non-detergent oil.
COMPRESSORS WITH OIL LEVEL GAUGE:
1. Turn the oil filling plug counter clockwise, pull it out.
2. The compressor is full when the oil level is between
the marks “H” and “L”. Replace oil filling plug.
3. Always maintain oil level between the mark “H” and
“L” in the oil glass.
DRAINING THE OIL:
1. Remove the oil drain plug and allow the oil to drain
completely.
2. Replace the oil drain plug. (we recommend use of a
sealing compound or Tefflon tape to avoid leakage).
3. Refill with the recommended oil, to proper level.
CHECKLIST
CHECKLIST
During the breaking-in period, nuts and bolts have a tendency
to loose up.After two weeks tighten all nuts and bolts including head
bolts. Then check everything once a month to make sure all nuts and
bolts stay tight.
