Drain tank daily or after each use. If tank develops a leak, replace it immediately with a new tank or replace the entire compressor.
I: V.._:l I'lm] WARNING: Risk of Electrical Shock WHAT CAN HAPPEN HOW TO PREVENT IT Your air compressor is powered by electricity. Like any other electrically powered device, If it is not used properly it may cause electric shock. Never operate the compressor outdoors when it is raining or in wet conditions. Repairs attempted by unqualified personnel can result in serious injury or death by electrocution.
I: F.._I.lI'lm] WARNING: RISK OF BURNS WHAT CAN HAPPEN HOW TO PREVENT IT Touching exposed metal such as the compressor head or outlet tubes, can result in serious burns. Never touch any exposed metal parts on compressor during or immediately after operation. Compressor will remain hot for several minutes after operation. Do not reach around protective shrouds or attempt maintenance until unit has been allowed to cool. I: F.._I.
I: V;YJ;I;1m] WARNING: RISK OF UNSAFE OPERATION WHAT CAN HAPPEN Unsafe operation of your air compressor could lead to serious injury or death to you or others, D26056 HOW TO PREVENT IT Review and understand all instructions and warnings in this manual. Become familiar with the operation and controls of the air compressor. Keep operating area clear of all persons, pets, and obstacles. Keep children away from the air compressor at all times.
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.

Wiring Instructions _ RISK OF ELECTRICAL SHOCK. Improper electrical grounding can result in electrical shock. The wiring should be done by a qualified electrician to comply with national and local electrical codes. A qualified electrician needs to knows the following before wiring: 1. 2. The amperage rating of the electrical box should be adequate. Refer to the product specifications, found in the front of this manual, for this information.

Know Your Air Compressor READ THIS OWNER'S MANUAL AND SAFETY RULES BEFORE OPERATING YOUR UNIT. Compare the illustrations with your unit to familiarize yourself with the location of various controls and adjustments. Save this manual for future reference. Description of Operation Become familiar with these controls before operating the unit. Tank Pressure Gauge: The tank pressure gauge indicates the reserve air pressure in the tank. Globe Valve (sold separately): Opens and closes air discharge valve.
Air Compressor Pump (not shown): Compresses air into the air tank. Working air is not available until the compressor has raised the air tank pressure above that required at the air outlet. Air Intake Filter (not shown) This filter is designed to clean air coming into the pump. This filter must always be clean and ventilation openings free from obstructions. See "Maintenance". Check Valve: When the air compressor is operating, the check valve is "open", allowing compressed air to enter the air tank.
5. Run the minutes. valve is minimal tank. 6. Check all air line fittings and connections/piping for air leaks by applying a soap solution. Correct if necessary. NOTE: Minor leaks can cause the air compressor to overwork, resulting in premature breakdown or inadequate performance. 7. 8. compressor for 20 Make sure the globe open and there is air pressure build-up in Check for excessive vibration. Readjust or shim air compressor feet, if necessary. After 20 minutes, close the globe valve.
Customer Responsibilities Before Every Every Every Every each 8 40 100 160 use hours hours hours hours Check Safety Valve Every 500 Yearly hours • Drain Tank Check Oil • • Change Oil Unusual Noise and/or Vibration 0 2 02 • Air Filter O1 Drive Belt-Condition • Motor Pulley/Flywheel alignment • Air compressor pump intake and exhaust valves Inspect air lines and fittings for leaks • • Head Bolts - Check the torques of the head bolts after the first five hours of operation.
To Drain Tank NOTE: Operation of the air compressor will cause condensation to build up in the air tank. Always drain tank on a washable surface or in a suitable container to prevent damaging or staining surfaces. 1. Set the On/Auto/Off lever to "OFF". 2. 3. 4. 5. 6. Close the globe valve. Remove the air tool or accessory. Open the globe valve and allow the air to slowly bleed from the air tank until tank pressure is approximately 20 psi. Close the globe valve.
Air Filter - Inspection Replacement and Hot surfaces. Risk of burn. Compressor heads are exposed when filter cover is removed. Allow compressor to cool prior to servicing. A dirty air filter will not allow the compressor to operate at full capacity. Keep the air filter clean at all times. 1. Remove the air filter cover. 2. Remove the air filter from filter cover. 5. Remove the belt and replace with a new one. 6. See the "Adjust Belt Tension" before tightening motor mounting screws.
7. Motor Pulley/Flywheel Alignment 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" to prevent excessive belt wear. The air compressor flywheel and motor pulley must be in-line (in the same plane) within 1/16" to assure belt retention within flywheel belt grooves. To check alignment, perform the following steps: 1.
Unit cycles automatically when power is on. When doing Maintenance, you may be exposed to voltage sources, compressed air or moving parts. Personal injuries can occur. Before performing any Maintenance or repair, unplug the compressor and bleed off all air pressure. 8, Unscrew the check valve (turn counterclockwise) using a 7/8" open end wrench. Note the orientation for reassembly. 6, Using a screwdriver, carefully push the valve disc up and down.
Motor 4. This motor has a manual thermal overload protector. If the motor overheats for any reason, the overload protector will shut off the motor. The motor must be allowed to cool down before restarting. To restart: IMPORTANT: If the overload protector shuts the motor off frequently, check for a possible voltage problem. Low voltage can also be suspected when: 1. 1. The motor does not get up to full power or speed. 2.
bd-'_o_!_oIo_ Performing repairs may expose voltage sources, moving parts or compressed air sources, moving parts or compressd air sources. Personal injury may occur. Prior to attempting any repairs, unplug the air compressor and bleed off all air tank air pressure. PROBLEM Excessive tank pressure (safety valv@ pops off. CAUSE CORRECTION Pressure switch does not shut off motor when compressor reaches "cutout" pressure. Pressure switch "cut-out" too high.
PROBLEM CAUSE CORRECTION If there is an excessive amount of pressure drop when the accessory is used, adjust the regulator as instructed in the Operation section. NOTE: Adjust the regulated pressure under flow conditions (while accesory is being used). Pressure reading on the regulated pressure gauge (if equipped) drops when an accessory is used. It is normal for "some" pressure drop to occur. Air leak from safety valve. Possible defect in safety valve.
PROBLEM Motor will not run. CAUSE Motor overload protection switch has tripped CORRECTION Let motor cool off and overload switch will automatically reset. Tank pressure exceeds _ressure switch "cut-in" %essure. Motor will start automatically when tank pressure drops below "cut-in" pressure of pressure switch. Check valve stuck open. Remove and clean, or replace. Loose electrical connections. Check wiring connection inside pressure switch and terminal box area.
PROBLEM CORRECTION CAUSE Knocking Noise. Possible defect in safety Excessive belt wear. Squealing sound. valve. Operate safety valve manually by pulling on ring. If valve still leaks, it should be replaced. Defective check valve. Remove and clean, or replace. Loose pulley. Tighten pulley set screw, 145-165 in.-Ibs. Loose flywheel. Tighten flywheel screw 33-37 ft.-Ibs. Compressor mounting screws loose. Tighten mounting 20-25 ft.-Ibs. Loose belt.
