SPECIFIC PRODUCT WARNINGS AND PRECAUTIONS

1. THIS AIR COMPRESSOR PUMP IS DESIGNED FOR USE ONLY WITH A

3 HORSEPOWER MOTOR 3,400 RPM (not included).

2. WARNING! Make sure to fill the Air Compressor Pump with a premium quality,

30-weight, non-detergent oil before each use. Running the Air Compressor

Pump with no oil or low oil will cause damage to the equipment.

3. WHEN FILLING WITH OIL: Make sure to unscrew (do not pull) the Oil Fill Plug

(part #20) out. (See Figure D.)

4. MAKE SURE ALLTOOLS AND EQUIPMENT USED WITH THE AIR

COMPRESSOR PUMP ARE RATED TO THE APPROPRIATE CAPACITY. Do

not use any tool or equipment that does not operate from 0 to 140 PSI.

5. MAINTAIN A SAFE WORKING ENVIRONMENT. Keep the work area well lit.

Make sure there is adequate surrounding workspace. Always keep the work

area free of obstructions, grease, oil, trash, and other debris. Do not use the Air

Compressor Pump in areas near flammable chemicals, dusts, and vapors.

6. AVOID INJURY: Never direct the Exhaust Elbow (part #3) at people or animals.

(See Figure D.)

7. AVOID BURNS: The Air Compressor Pump becomes very hot during use and for

a while after its use. Do not touch the Air Compressor Pump until it has com-

pletely cooled.

8. WARNING! DO NOT USETHE AIR COMPRESSOR PUMP UNTIL A PROP-

ERLY FUNCTIONING PULLEY/BELT GUARD (not included) HAS BEEN

INSTALLED. (See Figure C.)

SKU 09592 PAGE 4

10. WARNING! This product contains or produces a chemical known to the State of

California to cause cancer and birth defects (or other reproductive harm).

(California Health & Safety Code 25249.5 et seq.)

9. BEFORE PERFORMING ANY INSPECTION, MAINTENANCE, OR CLEANING

PROCEDURES, MAKE SURE ALL AIR PRESSURE HAS BEEN RELEASED

ber shown on the cover of this manual as soon as possible.

ASSEMBLY INSTRUCTIONS

NOTE: For additional references to the parts mentioned in the following pages, refer to

the Assembly Diagram on page 10.

SKU 09592 PAGE 5

To Attach The Air Compressor Pump To A Mounting Surface:

1. NOTE: Depending on your level of assembly expertise, you may wish to have a

qualified technician perform the assembly procedures.

2. CAUTION: Make sure the mounting surface (air compressor stand, work-

bench, etc.) to which the Air Compressor Pump will be attached is flat, level, and

sturdy enough to withstand the weight of the Air Compressor Pump and all other

necessary equipment and accessories.

3. At the base of the Air Compressor Pump are

four

3/8” mounting holes with a hole

pattern of 5-1/2” long by 7-1/2” wide. If

four

3/8” mounting holes with a hole

pattern of 5-1/2” long by 7-1/2” wide do not already exist in the mounting surface,

it will be necessary to drill the

four

3/8” mounting holes through the mounting

surface. IMPORTANT:Prior to drilling, make sure there are no electrical cables,

wires or other obstructions in the drilling path. (See Figure A.)

4. To do so, temporarily position the Air Compressor Pump in the desired location

on the mounting surface. Use the base of the Air Compressor Pump, with its four

3/8” mounting holes, as a template by which to mark the four 3/8” mounting holes

that are to be drilled through the mounting surface. Then, remove the Air Com-

pressor Pump from the mounting surface. NOTE: You may also follow the illus-

tration below by which to measure where each of the four 3/8” mounting holes

should be drilled. (See Figure A.)

5. Once the four 3/8” mounting holes are drilled through the mounting surface,

place the Air Compressor Pump on the mounting surface and align its four

mounting holes with the four drilled mounting holes on the mounting surface.

Then, secure the Air Compressor Pump to the mounting surface, using four 3/8”

Bolts of appropriate length, four Lockwashers, and four Nuts (all not included).

6. The Air Compressor Pump requires the use of a “V” Pulley Belt (not included).

The “V” Pulley Belt should be no wider than 1-5/16” wide at its widest point and

of appropriate length depending on the distance between the Air Compressor

Pump’s Pulley (part #38) and the 3 HP Motor’s Pulley (not included). Once the

“V” Belt Pulley is installed, its proper length is indicated by pushing down with

your finger midway on the “V” Belt Pulley. The “V” Belt Pulley should not de-

press more than 1/2”. (See Figure B.)

7. WARNING! To avoid personal injury and/or property damage, it is recommended

that a properly functioning Pulley/Belt Guard (not included) be installed. The

Pulley/Belt Guard should

fully

enclose (front, back, top, bottom) the Air Compres-

sor Pump’s Pulley (part #38), the “V” Belt, and the Motor’s Pulley. NOTE: Make

sure to allow for about 1” clearance, on all sides, between the Pulley/Belt Guard

and the Air Compressor Pump’s Pulley, the “V” Belt, and the Motor’s Pulley.

(See Figure C.)

OPERATING INSTRUCTIONS

NOTE: For additional references to the parts mentioned in the following pages, refer to

the Assembly Diagram on page 10.

To Check The Oil Level:

1. The Oil Window (part #25) is used to determine if oil is needed. To check the oil,

observe the Oil Window. The oil should appear at the midway point (horizon-

tally) in the circle of the Oil Window. (See Figure D.)

Note: The optimal capacity of the oil tank is 28.73 ounces.

8. Attach the Air Compressor Tank’s Inlet Hose (not included) to the 1/2” by 14-TPI

Exhaust Elbow (part #3). NOTE: Make sure to wrap the male threads of Tank’s

Inlet Hose

Connector

with pipe seal tape (not included). Then, screw the Con-

nector firmly into the Exhaust Elbow. (See Figure D.)

2. If the oil level is below the midway point in the Oil Window (part #25) then it is

necessary to add a

premium quality, 30-weight, non-detergent oil

until the level of

oil reaches the midway point in the Oil Window. Do not overfill. NOTE: Make

sure to unscrew the Oil Fill Plug and remove it from its Oil Fill Hole. Add the

new oil. Then screw the Oil Fill Plug back into the Oil Fill Hole, being careful not

to strip the threads. (See Figure D.)

SKU 09592 PAGE 8

4. IMPORTANT:After starting the Air Compressor Pump, it should run for about 30

minutes without a load in order for it to build up sufficient air pressure.

1. WARNING! Before performing any inspection, maintenance, and cleaning proce-

dures, make sure all air pressure has been released from the Air Compressor’s

Tank and that the Air Compressor is unplugged from its electrical outlet.

INSPECTION, MAINTENANCE, AND CLEANING

2. BEFORE EACH USE, inspect the general condition of the Air Compressor

Pump. Check all air fittings for leaks. Check for loose screws, misalignment or

binding of moving parts, cracked or broken parts, and any other condition that

may affect the safe operation of this equipment. If abnormal noise or vibration

occurs, immediately disconnect the Air Compressor from its electrical supply

source and have the problem corrected before further use.

Do not use damaged equipment.

3. DAILY: Check the Air Compressor Pump’s oil level. If necessary, fill with a pre-

mium quality, 30-weight, non-detergent oil. NOTE: When checking the oil level,

make sure to unscrew (do not pull) the Oil Fill Plug (part #20).

(See Figure D.)

4. EVERY 100 HOURS OF USE: Clean the Air Filter Element (part #4) with a mild

solvent. Then, dry and re-attach the Air Filter Element. NOTE: Replace the Air

Filter Element if it is too dirty to properly clean. (See Assy. Diagram.)

5. EVERY 500 HOURS OR 12 MONTHS: Replace the old oil with new, premium

quality, 30-weight, non-detergent oil.

6. TO CLEAN: wipe with a damp cloth, using a mild detergent or mild solvent.

7. WHEN STORING: Keep the Air Compressor Pump in a clean, dry location.

3. Start the Air Compressor, and visually check the “V” Belt for proper tension. Also

check for air leaks in the system, abnormal noise or vibration. If a problem oc-

curs immediately disconnect the Air Compressor from its electrical supply source,

release all air pressure from the system, and have the problem corrected before

further use.
