WARNING: RISK OF BURSTING

Air Tank: On February 26, 2002, the U.S. Consumer Product Safety Commission published Release U 02-108 concerning air compressor tank safety:
Air compressor receiver tanks do not have an infinite life. Tank life is dependent upon several factors, some of which include operating conditions, ambient conditions, proper installations, field modifications, and the level of maintenance. The exact effect of these factors on air receiver life is difficult to predict.
If proper maintenance procedures are not followed, internal corrosion to the inner wall of the air receiver tank can cause the air tank to unexpectedly rupture allowing pressurized air to suddenly and forcefully escape, posing a risk of injury to consumers.
Your compressor air tank must be removed from service by the end of the year shown on your tank warning label. The following conditions could lead to a weakening of the air tank, and result in a violent air tank explosion:

What can happen How to prevent it
Failure to properly drain condensed water from the air tank causes rust and thinning of the steel air tank. Drain the air tank daily or after each use. If the air tank develops a leak,
replace it immediately with a new air tank or replace the entire compressor.
Modifications or attempted repairs to the air tank. Never drill into, weld, or make any modifications to the air tank
or its attachments. Never attempt to repair a damaged or leaking air
tank. Replace with a new air tank.
Unauthorized modifications to the safety valve or any other components which control air tank pressure. The air tank is designed to withstand specific operating pressures. Never make adjustments or parts substitutions to alter the factory set operating pressures.
Attachments & 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. Follow the equipment manufacturer’s 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.
Tires:
Over inflation of tires could result in serious injury and property damage. Use a tire pressure gauge to check the tire pressure before each use and while inflating tires; see the tire sidewall for the correct tire pressure.
NOTE: Air tanks, compressors and similar equipment used to inflate tires can fill small tires similar to these very rapidly. Adjust the pressure regulator on the air supply to no more than the rating of the tire pressure. Add air in small increments and frequently use the tire gauge to prevent over inflation.

Electrical Wiring
WARNING: Improper electrical installation of this product may void its warranty and your fire insurance. Has circuit wiring performed by qualified personnel such as a licensed electrician who is familiar with the current national electrical code and any prevailing local electrical codes?
WARNING: Risk of electrical shock. Improper electrical grounding can result in electrical shock.

The wiring should be done by a qualified electrician.
A qualified electrician needs to know the following before wiring:

  • The amperage rating of the electrical box is adequate.
    Refer to the Specifications, in the instruction manual, for this information.
  • If the supply line has the same electrical characteristics (voltage, cycle, phase) as the motor. Refer to the motor nameplate, on side of the motor, for this information.

NOTE: The wiring used must be rated for the motor nameplate voltage, plus or minus 10%. Refer to local codes for recommended wire sizes, correct wire
size and maximum wire run.
Undersized wire causes high amp draw and overheating to the motor.
NOTE: A circuit breaker is recommended. If the air compressor is connected to a circuit protected by a fuse, use only time-delay fuses.
WARNING: Risk of electrical shock. Electrical wiring must be located away from hot surfaces such as manifold assembly, compressor outlet tubes, heads, or cylinders.

Air Distribution System
WARNING: Risk of bursting. Plastic or PVC pipe is not designed for use with compressed air. Regardless of its indicated pressure rating, plastic pipes can burst from air pressure. Use only metal pipes for air distribution lines.

INSTALLING AND DISCONNECTING HOSES

WARNING: Risk of unsafe operation. Firmly grasp hose in hand when installing or disconnecting to prevent hose whip. Ensure the regulated pressure gauge reads 0 PSI.

The next figure represents a typical air distribution system.
The following are tips to remember when setting up the air compressor’s air distribution system.
NOTE: Compressed air from oil lubed air compressors will contain water condensation and oil mist. Several drains, traps, and filters will be needed to supply air without water (including aerosols) or oil to spray equipment, air tools, and accessories requiring filtered air. Always read the instructions for the air tools and accessories being used.

  • Use a pipe that is the same size as the air tank outlet. Piping that is too small will restrict the flow of air.
  • If piping is over 100′ (30.5 m) long, use the next larger size.
  • Bury underground lines below the frost line and avoid pockets where condensation can gather and freeze. Apply pressure before underground lines are covered to make sure all pipe joints are free of leaks.
  • A flexible coupling is recommended to be installed between the globe valve/air discharge outlet and main air distribution line to allow for vibration.
  • A separate regulator is recommended to control the air pressure. Air pressure from the tank is usually too high for individual air-driven tools.
  • DO NOT install lubricators between the tank and any spray equipment, air tool or accessory requiring oil-free filtered air.
  • Drain all traps, filters, and dirt legs daily.

NOTICE: Risk of property damage. Use air compressor oil only. Multi-weight automotive engine oils like 10W30 should not be used in air compressors. They leave carbon deposits on critical components, thus reducing performance and compressor life.
NOTE: Use full synthetic, non-detergent air compressor oil.
NOTE: Crankcase oil capacity is approximately 16 fluid ounces
(473 ml).
To Check

WARNING: Drain tank to release air pressure before removing the oil fill plug or oil drain plug.

  1. Remove the oil fill plug (14).
  2. Remove the oil drain plug (16) and drain the oil into a suitable container.
  3. Replace the oil drain plug and tighten it securely
  4. Slowly add compressor oil until it reaches the middle of the sight glass (15). NOTE: When filling the crankcase, the oil flows very slowly into the pump. If the oil is added too quickly, it will overflow and appear to be full.
    CAUTION: Overfilling with oil will cause premature compressor failure. Do not overfill.
  5. Replace the oil fill plug and tighten securely.

To Replace Belt

WARNING: This unit starts automatically.
ALWAYS shut off and unplug the compressor, and bleed all pressure from the system before servicing the compressor, and when the compressor is not in use. Do not use the unit with the shrouds or belt guard removed. Serious injury could occur from contact with moving parts. Hot surfaces. Risk of burn. The pump head and surrounding parts are very hot and do not touch them (see the Hot Surfaces identified in Fig. A). Allow the compressor to cool prior to servicing.

  1. Move the Auto/Off switch to “OFF (O)”, unplug the unit, and relieve all air pressure from the air tank.
  2. Remove the outer belt guard.
  3. Mark motor position on the saddle.
  4. Loosen the motor mounting screws and slide the motor toward the air compressor pump.
  5. Remove the belt and replace it with a new one.
  6. See the Adjusting Belt Tension before tightening motor mounting screws.

To Adjust Belt Tension

  1. Slide motor into original position, line the motor up with the mark made earlier on the saddle.
  2. Tighten two outside motor mounting screws enough to hold the motor in place for checking pulley and flywheel alignment.
  3. The belt should deflect 1/4″ (6.5 mm) at midway between the pulley and the flywheel when a 10-pound (4.5 kg.) weight is applied at the midway point.
  4. When proper belt tension is achieved, tighten motor mounting screws. Torque to 20-25 ft-lbs (27.1-33.9 Nm)

NOTE: Once the motor pulley has been moved from its factory-set location, the grooves of the flywheel and pulley must be aligned to within 1/16″ (1.6 mm) to prevent excessive belt wear. Verify the alignment by performing the following Motor Pulley/Flywheel – Alignment.

To Align Motor Pulley/Flywheel

NOTE: Once the motor pulley has been moved from its factory-set location, the grooves of the flywheel and pulley must be aligned to within 1/16″ (1.6 mm) to prevent excessive belt wear.
The air compressor flywheel and motor pulley hub must be in-line (in the same plane) within 1/16″ (1.6 mm) to assure belt retention within flywheel belt grooves. To correct misalignment, perform the following steps:

  1. Move the Auto/Off switch to “OFF (O)”, unplug the unit, and relieve all air pressure from the air tank.
  2. Remove the outer belt guard.
  3. Loosen the motor mounting bolts.
  4. Loosen the set-screws on the motor pulley.
  5. Align the motor pulley with the pump flywheel.
  6. Retighten the motor pulley set screws. Torque 115-125 in.-lbs (13.0 – 14.1 Nm).
  7. Adjust the proper belt tension.
  8. Retighten the motor mounting bolts. Torque to 20-25 ft.-lbs (27.1–33.9 Nm)
  9. Reinstall the outer belt guard. All moving parts must be guarded.

To Check Air Compressor Pump Intake and Exhaust Valves
Once a year have a Trained Service Technician check the air compressor pump intake and exhaust valves.
To Inspect Air Lines and Fittings for Leaks

  1. Move the Auto/Off switch to “AUTO (-)” and allow tank pressure to build. The motor will stop when tank pressure reaches “cut-out” pressure.
  2. Move the Auto/Off switch to “OFF (O)” and unplug the unit.
  3. Apply a soap solution to all air-line fittings and connections/piping to look for any leaks.
  4. Pull ring on safety valve allowing air to bleed from the tank until tank pressure is approximately 20 PSI.
    Release the safety valve ring.
  5. Drain water from the air tank by opening the drain valve on the bottom of the tank.
  6. Correct any leaks found.

IMPORTANT: Even minor leaks can cause the air compressor to overwork, resulting in premature breakdown or inadequate performance.

To Check Air Compressor Pump Head Bolt Torque
The air compressor pump head bolts should be kept properly torqued. Check the torques of the head bolts after the first five hours of operation. Torque to 15-20 ft.-lbs. (20.3-27.1 Nm).

SERVICE AND ADJUSTMENTS

ALL MAINTENANCE AND REPAIR OPERATIONS NOT LISTED MUST BE PERFORMED BY A TRAINED SERVICE TECHNICIAN.
WARNING: Risk of unsafe operation. Unit cycles automatically when power is on. When servicing, you may be exposed to voltage sources, compressed air, or moving parts. Before servicing the unit unplugs or disconnects the electrical supply to the air compressor, bleed the tank of pressure, and allow the air compressor to cool.

To Replace or Clean Check Valve

  1. Release all air pressure from the air tank. See Draining Air Tank in the Maintenance section.
  2. Move the Auto/Off switch to “Off (O)”, unplug the unit, and relieve all air pressure from the air tank.
  3. Using an adjustable wrench loosen the outlet tube nut at the air tank and pump. Carefully move the outlet tube away from the check valve.
