2INTRODUCTION

1.1 GENERAL COMPRESSOR SAFETY PRECAUTIONS

Safety is a prime consideration in the design and manufacture of the compressor. Ultimately, the respon-

sibility for safe operation rests with the individuals who use and maintain the compressor. The following

safety precautions are offered as a guide for the safe operation and maintenance of this machinery.

»Only trained and authorized personnel who have read and understand this operator’s manual should

operate the air compressor. Failure to follow the instructions, procedures and safety precautions in

this manual will increase the possibility of accidents and injuries.

»Never start the compressor unless it is safe to do so. Do not attempt to operate the air compressor

with a known unsafe condition. If an unsafe condition exists or maintenance is required, disconnect

and lockout the main power source to render it inoperative and tag the air compressor so others

who may not know of the unsafe condition cannot attempt to operate it until the unsafe condition is

corrected.

»Use and operate the air compressor only in full compliance with all pertinent Federal, State and Local

codes or requirements including OSHA, EPA and other relevant agency requirements.

»Do not modify this compressor without consulting the manufacturer and receiving specic written

approval.

»Do not use accessories (such as tools, valves, lters, hoses, piping dryers, etc.) that are rated lower

than the maximum pressure or temperature rating of this air compressor. Do not exceed the accessory

component manufacturer’s rated safe operating pressure or temperature for these items.

»Air gun cleaning devices must not be used at pressures above 30 psi (2 bar). Always use an

appropriate regulator to reduce pressure at the cleaning tool and always use with effective chip

guarding and personal protective equipment per OSHA Standard 29 CFR 1910.242 (b).

»Keep all parts of the body away from all potential points of air discharge, including pressure relief

valve ports, hoses or tools.

»Avoid bodily contact with hot oil, hot surfaces, sharp edges and corners.

»Serious injury or death may result from horseplay with air hoses and compressed air. Do not do it, do

not allow it!

»Do not operate the compressor if there is a possibility of it ingesting ammable, toxic or explosive

fumes, mists or particulate.

»Do not operate the compressor with its fan guard removed.

»Keep clothing, hands, arms and other parts of the body away from the fan and drive coupling.

»Wear OSHA approved personal protective gear including gloves, safety shoes, safety glasses, head

covering and ear protection when working on or around the compressor.

»Wear snug-tting clothing (no neckties) and conne long hair when working around the compressor.

»Keep an adequate rst-aid kit nearby. Obtain medical assistance promptly in case of injury. Do not

ignore small cuts, burns or minor eye injuries as they may lead to infection.

»Do not use air from this compressor for breathing, as it may contain colorless, odorless yet lethal

gases. Severe injury or death may result within a few seconds.

»Do not permit air from this compressor to contact foodstuff except in compliance with FDA Standard

21 CFM 178.3570 and all other applicable regulations. Use food grade lubricant for such applications.

»Keep all parts of the body, tools or other conductive objects away from exposed live parts of the

electrical system. Maintain dry footing, stand on insulating surfaces and do not contact any other

portion of the compressor when making adjustments.

Not all hazards can be anticipated, and the operator of the equipment is ultimately responsible for identify-

ing hazardous and dangerous conditions, avoiding dangerous operation and preventing accidents.

1.2 SAFETY DECALS

Sullivan-Palatek compressors are all equipped with brightly colored, weather-resistant, pictorial/verbal

decals. These are designed to warn the operator against potential hazards in order to minimize risk of

property damage, bodily injury and/or death. The warning decals are located where the danger is most

prevalent. All operators must be aware of the warning decals and follow the instructions.

3INTRODUCTION

If any warning decals are missing, damaged, painted over or located in such a position as to be unread-

able in a given installation, new warning decals must be ordered. Be sure they are properly positioned

and installed correctly. If any operators are not fully conversant with the English language and/or cannot

comprehend the intended pictorial warnings, it becomes incumbent upon the owner, lessor or other

responsible administrator to be sure the operator is properly trained, made aware of and understands the

meaning of all warning decals.

1.3 SCREW COMPRESSOR AIREND EXCHANGE PROGRAM

After the warranty period has expired a factory-remanufactured airend can be purchased on an exchange

basis. All bearings and seals have been replaced. All other parts not meeting our quality standards are also

replaced. A remanufactured airend has a warranty which is 12 months from start-up date or 18 months

from date of shipment in accordance with the terms set forth in the new airend warranty found on the

previous pages.
