Summary

Safety Warnings

Risk of Asphyxiation

Inhaling compressed air may contain harmful substances.

Risk of Bursting

Improper maintenance or modification of air tanks can cause explosion.

Risk of Electrocution or Electrical Shock

Improper grounding or wet conditions can lead to shock.

Risk of Explosion or Fire

Sparks or flammable vapors near hot parts can cause ignition.

Safety Warnings (Continued)

Risk from Moving Parts

Contact with belts, pulleys, or fans can cause serious injury.

Risk of Burn

Touching hot engine or compressor parts can cause burns.

Risk of Injury from Lifting

Lifting objects too heavy for one person can cause injury.

Flying Objects

Debris propelled by air stream can cause eye injury.

Risk of Unsafe Operation

Improper use or fatigue can lead to injury or death.

Risk of Damage to Air Compressor or Property

Improper transport or operation can cause leaks and damage.

System Controls

Safety-Relief Valve

Discharges tank pressure to prevent over-pressurization.

Manual Overload / Motor Reset

Protects motor from overheating by tripping a reset button.

Pressure Switch

Automatically starts/stops compressor based on tank pressure.

Regulator – Working Pressure

Adjusts and displays the output pressure for tools.

Pressure Gauge(s)

Measures tank or output pressure.

Drain Valve(s)

Allows moisture to be drained from the storage tank.

Air Intake Filter

Prevents foreign matter from entering the pump or engine.

System Controls (Continued)

Pilot-Unloader Valve

Manages compressor operation based on tank pressure settings.

Sight Gauge/Dipstick

Used to check and maintain the oil level in the pump.

Check Valve

Maintains tank pressure and aids loadless starts.

Breather/Oil Fill Plug

Vents crankcase pressure; must be in place for operation.

Automatic-Idle Control

Reduces engine speed during idle periods on gas units.

Cold-Start Valve

Allows motor/pump to warm up before engaging pressure.

Schmidt Belt-Tightening Device (For Gas Units Only)

Unique system for maintaining proper belt tension on gas units.

Vibration Dampener(s)

Rubber pads protect the tank assembly from vibration.

Engine Kill Switch

Stops the engine quickly.

Engine Choke

Assists in starting a cold engine.

Fuel Shut-Off Valve

Controls fuel flow to the engine.

Pre-Start Checklist

Always Operate the Compressor in a Level Position

Ensures proper oil submersion and prevents damage.

Operate in a Clean, Dry and Well Ventilated Area

Ensures proper cooling and prevents air contamination.

Check Oil Level Daily and Change at Regular Intervals

Critical for pump lubrication and longevity.

Inspect/Clean/Change Intake Elements on a Regular Basis

Prevents premature wear caused by dirt ingestion.

Use Longer, Properly Sized Air Hose Rather Than Extension Cords

Extension cords can cause voltage drop and affect performance.

Do Not Use a Generator as the Power Source

Generators may not provide sufficient starting wattage.

Maintain Rubber Vibration Pads

Essential for preventing premature compressor failure.

Drain Moisture from Air Tanks Daily

Combats internal tank corrosion.
