How To Prevent It

What Could Happen

WARNING: Risk from Flying Objects

HOW TO PREVENT IT

WHAT CAN HAPPEN

The compressed air stream can cause soft tissue damage to exposed skin and can propel dirt, chips, loose particles,

and small objects at high speed, resulting in property damage or personal injury.

Always wear ANSI Z87.1 approved safety glasses with side shields when using the compressor.

Never point any nozzle or sprayer toward any part of the body or at other people or animals.

Always turn the compressor off and bleed pressure from the air hose and

tank before attempting maintenance, attaching tools or accessories.

HAZARD

Drain tank daily or after each use. If

tank develops a leak, replace it immediately with a new tank or replace the entire compressor.

1. Failure to properly drain

condensed water from tank, causing rust and thinning of the steel tank.

2. Modifications or attempted repairs to the tank.

3. Unauthorized modifications to the unloader valve, safety valve, or any other components which control tank pressure.

Never drill into, weld, or make any modifications to the tank or its

attachments.

4. Excessive vibration can weaken the air tank and cause rupture or explosion

The tank is designed to withstand specific operating pressures. Never make

adjustments or parts substitutions to alter the factory set operating pressures.

For essential control of air pressure, you must install a pressure regulator and pressure gauge to the air outlet (if not equipped) of your compressor. Follow the

equipment manufacturers recommendation and never exceed the maximum allowable pressure rating of attachments. Never use compressor to

inflate small low pressure objects such as children’s toys, footballs, basketballs, etc.

TTACHMENTS & ACCESSORIES:

Exceeding the pressure rating of air tools, spray guns, air operated

accessories, tires, and other inflatables can cause them to explode or fly apart, and could result in serious injury.

GLOSSARY

DUTY CYCLE

Air compressors should be operated on not more than a 50% duty cycle. This means an air compressor that pumps air more than 50% of one hour is considered misuse, because the air compressor is undersized for the required air demand. Maximum compressor pumping time per hour is 30 minutes.

Accessories for this unit are available at the store the unit was purchased.

ACCESSORIES

Become familiar with these terms before operating the unit.

CFM: Cubic feet per minute. SCFM: Standard cubic feet per minute; a unit of measure of air delivery. PSIG: Pounds per square inch gauge; a unit of measure of pressure. Code Certification: Products that bear one or more of the following marks:

UL, CUL, ETL, CETL, have been evaluated by OSHA certified independent safety laboratories and meet the applicable Underwriters Laboratories Standards for Safety.

Cut-In Pressure: While the motor is off, air tank pressure drops as you continue to use your accessory. When the tank pressure drops to a certain low level the motor will restart automatically. The low pressure at which the motor automatically restarts is called “cut-in” pressure.

Cut-Out Pressure: When an air compressor is turned on and begins to run, air pressure in the air tank begins to build. It builds to a certain high pressure before the motor automatically shuts off - protecting your air tank from pressure higher than its capacity. The high pressure at which the motor shuts off is called "cut-out” pressure.

Branch Circuit: Circuit carrying electricity from electrical panel to outlet.
