dust when you cut, sand,

drill or grind materials

such as wood, paint, metal,

concrete, cement, or other masonry.

This dust often contains chemicals

known to cause cancer, birth defects,

or other reproductive harm. Wear

protective gear.

GENERAL SAFETY

Since the air compressor and other

components (material pump, spray

guns, filters, lubricators, hoses,

etc.) used, make up a high pressure

pumping system, the following safety

precautions must be observed at all

times:

1. Read all manuals

included with this

product carefully. Be

thoroughly familiar with

the controls and the proper use of

the equipment.

2. Follow all local electrical and safety

codes as well as in the United

States, the National Electrical Codes

(NEC) and Occupational Safety and

Health Act (OSHA).

3. Only persons well acquainted

with these rules of safe operation

should be allowed to use the

compressor.

4. Keep visitors away and NEVER

allow children in the work area.

5. Wear safety glasses and

use hearing protection

when operating the

unit.

6. Do not stand on or use the unit as

a handhold.

7. Before each use, inspect

compressed air system and

electrical components for signs of

damage, deterioration, weakness

or leakage. Repair or replace

defective items before using.

8. Check all fasteners at frequent

intervals for proper tightness.

Motors,

electrical

equipment and controls can

cause electrical arcs that

will ignite a ﬂammable gas

or vapor. Never operate or repair in or

near a ﬂammable gas or vapor. Never

store ﬂammable liquids or gases in the

vicinity of the compressor.

Compressor parts may

be hot even if the unit is

stopped.

9. Keep fingers away from a

running compressor; fast moving

and hot parts will cause injury and/

or burns.

10. If the equipment should start

to vibrate abnormally, STOP

the engine/motor and check

immediately for the cause.

Vibration is generally a warning of

trouble.

11. To reduce fire hazard, keep engine/

motor exterior free of oil, solvent,

or excessive grease.

An ASME code

safety relief valve

with a setting no higher than 170 psi

MUST be installed in the tank for this

compressor. The ASME safety valve

must have sufﬁcient ﬂow and pressure

ratings to protect the pressurized

components from bursting.

See compressor

speciﬁcation decal

for maximum operating pressure.

Do not operate with pressure switch

or pilot valves set higher than the

maximum operating pressure.

12. Never attempt to adjust ASME

safety valve. Keep safety valve

free from paint and other

accumulations.

Never use plastic

(PVC) pipe for

compressed air. Serious injury or death

could result.

Never

attempt

to repair or modify a tank!

Welding, drilling or any

other modiﬁcation will

weaken the tank resulting in damage

from rupture or explosion. Always

replace worn, cracked or damaged

tanks.

Drain liquid from

tank daily.

13. Tanks rust from moisture build-up,

which weakens the tank. Make

sure to drain tank regularly and

inspect periodically for unsafe

conditions such as rust formation

and corrosion.

14. Fast moving air will stir up dust

and debris which may be harmful.

Release air slowly when draining

moisture or depressurizing the

compressor system.

SPRAYING PRECAUTIONS

Do not

spray

ﬂammable materials in

vicinity of open ﬂame

or near ignition sources

including the compressor unit.

15. Do not smoke when spraying paint,

insecticides, or other flammable

substances.

16. Use a face mask /

respirator when spraying

and spray in a well

ventilated area to

prevent health and fire

hazards.

17. Do not direct paint or other

sprayed material at the compressor.

Locate compressor as far away

from the spraying area as

possible to minimize overspray

accumulation on the compressor.

18. When spraying or cleaning with

solvents or toxic chemicals, follow

the instructions provided by the

chemical manufacturer.

Introduction

Refer to Figure 2 to locate the

following items.

On/Off Switch — This unit is

equipped with an illuminated

On / Off switch. In the “ON” position

the button will be depressed and

the switch will light up. The switch

will remain lit as long as the button

is depressed and there is power to

the unit. The pressure switch will

automatically turn the pump / motor

on or off based on the pressure inside

the tank. If the unit is unplugged the

light will not be on. In the “OFF”

position the switch will not be

depressed and the light will not be on.

MANUAL

MW2500 Series

Operating Instructions and Parts List

Introduction (Continued)

Pressure Switch (located

internally) - When the compressor

is turned ON, this switch will shut

compressor off automatically when

tank pressure reaches maximum shut-

off / cut-out pressure. If compressor

remains on and air is depleted from

tank, this switch will allow compressor

to automatically restart at the restart /

cut-in pressure.

Regulator - The regulator controls

the amount of air pressure released at

the hose outlet. Turning the regulator

knob clockwise (to the right) will

increase air pressure at the outlet.

Turning the knob counter-clockwise

(to the left) will lower air pressure to

the outlet. Turning knob fully counter-

clockwise will shut off flow of air

completely.

Pressure Gauges - There are two

gauges on this compressor. These

gauges read air pressure in pounds

per square inch (psi). The larger

gauge shows pressure at the outlet.

Make sure this gauge reads ZERO

(by adjusting the regulator) BEFORE

changing air tools or disconnecting

hose from outlet. The small gauge

shows pressure in the tank indicating

compressor is building pressure

properly.

Installation

LOCATION

It is extremely important to use the

compressor in a clean, well ventilated

area where the surrounding air

temperature will not be more than

104°F.

A minimum clearance of 18 inches

between the compressor and a wall

is required because objects could

obstruct air flow.

Do not locate the

compressor

air inlet near steam, paint spray,

sandblast areas or any other source

of contamination. This debris will

damage the motor.

GROUNDING INSTRUCTIONS

1. This product is for use on a

nominal 120 volt circuit and has a

grounding plug that looks like the

plug illustrated in Figure 3. Make

sure the product is connected

to an outlet having the same

conﬁguration as the plug. This

product must be grounded. In

the event of an electrical short

circuit, grounding reduces risk of

electrical shock by providing an

escape wire for electric current.

This product is equipped with a

cord having a grounding wire

with an appropriate grounding

plug. Plug must be plugged into

an outlet that is properly installed

and grounded in accordance with

all local codes and ordinances.

ASME Safety Valve - This valve

automatically releases air if the tank

pressure exceeds the preset maximum.

Handle - Designed to move the

compressor.

Drain Valve - This valve is located on

the bottom of the tank. Use this valve

to drain moisture from the tank daily

to reduce the risk of corrosion.

Motor Reset - (not shown, located

inside motor). If the unit is over

worked, a motor reset (also known as

an overload protector) will shut the

unit off.

This compressor is

equipped with an

overload protector which will shut off

motor if it becomes overloaded.

If the unit shuts off, place ON / OFF

switch in the OFF position and wait

approximately 30 minutes for unit to

cool down. Turn switch to ON position

again to resume work.

If the overload

protector is

actuated, the motor must be allowed

to cool down for approximately 30

minutes before it will reset.

Installation (Continued)

Improper

use of

grounding plug can result in

a possible risk of electrical

shock!

Do not use a

grounding adapter

with this product!

2. If repair or replacement of cord or

plug is necessary, do not connect

grounding wire to either ﬂat blade

terminal. The wire with insulation

having an external surface that

is green (with or without yellow

stripes) is the grounding wire.

Never connect

green (or green

and yellow) wire to a live terminal.

3. Check with a qualiﬁed electrician

or serviceman if grounding

instructions are not completely

understood, or if in doubt as

to whether product is properly

grounded. Do not modify plug

provided; if it will not ﬁt outlet,

have proper outlet installed by a

qualiﬁed electrician.

Overheating, short

circuiting and ﬁre

damage will result from inadequate

wiring.

LUBRICATION

This is an oilless product and DOES

NOT require lubrication to operate.

Pre-Operation

BEFORE FIRST START-UP

BREAK-IN PROCEDURE

(Complete this procedure before

using compressor for the first time.

Once completed, it is not necessary to

repeat.)

1. Turn regulator knob fully clockwise

(to the right) to open air ﬂow.

2. Do not attach a hose or any other

ﬁtting to the compressor.

3. Turn ON / OFF switch to OFF

position.

4. Plug in power cord.

5. Turn ON / OFF switch to ON

position and run compressor for 30

minutes.

6. Turn ON / OFF switch to OFF

position.

7. Unplug power cord.

The compressor is now ready for use.

BEFORE EACH START-UP

OPERATING PROCEDURE

1. Turn regulator knob fully

counterclockwise (to the left) to

close air ﬂow.

2. Connect air hose to outlet of

regulator.

3. Turn ON / OFF switch to OFF

position.

4. Plug in power cord.

5. Turn ON / OFF switch to ON

position and let compressor run

until it reaches automatic shutoff

pressure.

6. Attach tire chuck or tool to end of

hose.

7. Turn regulator knob clockwise (to

the right) to desired pressure of

tool being used.

Operation

START-UP

Do not attach air

tools to open end

of the hose until start-up is completed

and the unit checks OK.

ON / OFF CYCLING OF COMPRESSOR

In the ON / AUTO position, the

compressor pumps air into the tank.

When a shut-off (preset “cut-out”)

pressure is reached, the compressor

automatically shuts off.

If the compressor is left in the

ON / AUTO position and air is depleted

from the tank by use of a tire chuck,

tool, etc., the compressor will restart

automatically at its preset “cut-in”

pressure. When a tool is being used

continuously, the compressor will cycle

on and off automatically.

In the OFF position, the pressure

switch cannot function and the

compressor will not operate. Make

sure switch is in OFF position when

connecting or disconnecting power

cord from electrical outlet.

PRESSURE GAUGES

The large gauge next to the regulator

knob indicates air pressure going to

hose (and any tool attached to end of

hose).

The small gauge next to the safety

valve indicates air pressure in tank.

MOISTURE IN COMPRESSED AIR

Moisture in compressed air will form into droplets as it comes from an

air compressor pump. When humidity is high or when a compressor is in

continuous use for an extended period of time, this moisture will collect

in the tank. When using a paint spray or sandblast gun, this water will be

carried from the tank through the hose, and out of the gun as droplets mixed

with the spray material.

IMPORTANT: This condensation will cause water spots in a paint job,

especially when spraying other than water based paints. If sandblasting, it

will cause the sand to cake and clog the gun, rendering it ineffective.

A ﬁlter in the air line, located as near to the gun as possible, will help

eliminate this moisture.
