Safety Signal Words ardous situation which, if not avoided, MAY result in minor or moderate injury.
Safety Instructions (continued) 19. When spraying with solvent or toxic chemicals, follow instructions provided by the chemical manufacturer. 8. Follow all local electrical and safety codes, as well as the National Electrical Code (NEC) and the Occupational Safety and Health Act (OSHA). 20. Spray in a well ventilated area, to keep fumes from collecting and causing health and fire hazards. 9. Wiring and fuses should follow electrical codes, current capacity, and be properly grounded. 21.
Spraying Precautions ! 3. Do not direct paint or other sprayed material at the compressor. Locate compressor as far away from the spraying area as possible to minimize overspray accumulation on the compressor. WARNING: Do not spray flammable materials in vicinity of open flame or near ignition sources including the compressor unit. 4. When spraying or cleaning with solvents or toxic chemicals, follow the instructions provided by the chemical manufacturer. 1.
Safety Instructions (continued) Warning Labels Find and read all warning labels found on the air compressor shown below DK724100AV 1000 6
Motor Specifications and Electrical Requirements Power Supply and Motor Specifications ! The A-C motor used on this compressor is a capacitor start, capacitor run nonreversible induction type, having the following specifications. It is wired at the factory for operation on 110V-120V AC, 60 Hz service. WARNING: To reduce the risk of electrical hazards, fire hazards or damage to the tool, use proper circuit protection. Your tool is wired at the factory for operation using the voltage shown.
Motor Specifications and Electrical Requirements (continued) 110-120 volt, 60Hz Tool Information If the grounding instructions are not completely understood, or if you are in doubt as to whether the tool is properly grounded check with a qualified electrician or service personnel. The plug supplied on your tool may not fit into the outlet you are planning to use. Your local electrical code may require slightly different power cord plug connections.
Changing Motor Voltage NOTE: The motor is prewired at the factory for 120V operation. Use the following procedure to change motor voltage to 240V. Hitch pin Motor voltage selector switch 1. Unplug the power cord before making or modifying connections. 2. Remove the hitch pin. 3. Toggle the motor voltage selector switch from 120V to 240V. Retaining screw 4. Install the hitch pin. 5. Unscrew the pressure switch cover retaining screw and remove the pressure switch cover. 6.
Motor Specifications and Electrical Requirements (continued) Thermal Overload Protector ! CAUTION: This compressor is equipped with an automatic reset thermal overload protector which will shut off motor if it becomes overheated. 4. Lack of proper ventilation. 5. Unit is being used with an extension cord. See Troubleshooting Chart for corrective action. ! CAUTION: The motor must be allowed to cool down before start-up is possible.
Glossary of Terms (continued) Line Pressure Gauge Displays the current line pressures. It is regulated by the regulator knob. Regulator A control that adjusts the line pressure to the proper amount needed to operate spray guns and air tools. Cut-in/Cut-off Pressure Specific psi at which a compressor starts and stops while refilling the air tank. Tank Pressure Gauge Indicates tank pressure in psi. Unpacking and Checking Contents 1. Remove the air compressor from the carton. ! 2.

9. Regulated Outlet Gauge. This gauge shows at-a-glance, air pressure at outlet. Air pressure is measured in pounds per square inch (PSI). Most tools have maximum pressure ratings. Never exceed the maximum pressure rating of the tool you are using. Be sure this gauge reads ZERO before changing air tools or disconnecting hose from outlet. 1. Belt Guard. The belt guard encloses the pulleys and drive belt. It protects the user from moving parts and directs cooling air to the compressor pump. 2. Air Filter.
Operating Your Air Compressor All lubricated compressor pumps discharge some condensed water and oil with the compressed air. Install appropri- ate water/oil removal equipment and controls as necessary for the intended application. Moisture in Compressed Air IMPORTANT: This condensation will cause water spots in a paint job, especially when spraying other than water based paints. If sandblasting, it will cause the sand to cake and clog the gun, rendering it ineffective.
Operating Your Air Compressor 1. Remove the dipstick and fill pump to the proper oil level. See Lubrication Section. 8. After use, turn pressure switch knob to the OFF position. 2. Open tank drain valves and turn regulator knob counterclockwise. 9. If compressor is not used for a long period of time, bleed air from line and use drain valve to drain water from the valves and tank. Afterwards, follow the proper schedule of maintenance. 3. Turn pressure switch knob to OFF position and plug in power cord.
Operating Your Air Compressor (continued) For Trouble-Free Operation sure to close tank drain valves before operating compressor. 1. Read instructions: Carefully read through this operator’s manual BEFORE OPERATING the new air compressor. It contains information about operation and maintenance of the unit. 3. Change air filter: Never run compressor without an air filter nor with a clogged air filter. Replace with a new filter when the element is dirty. 2.
Maintenance ! WARNING: Release all pressure and disconnect power before making any repair. 1. Check compressor for any visible problems, especially check air filter to be sure it is clean. 2. Pull ring on safety valve and allow it to snap back to normal position. ! 4. Turn power OFF and clean dust and dirt from motor, tank, air lines and pump cooling fins.
Maintenance (continued) Tank ! DANGER: Never attempt to repair or modify a tank! Welding, drilling or any other modification will weaken the tank resulting in damage from rupture or explosion. Always replace worn, cracked or damaged tanks. Tank Drain (2) NOTICE: Drain liquid from tanks daily. The tanks should be carefully inspected at a minimum of once a year. Look for cracks forming near the welds. If a crack is detected, remove pressure from tank immediately and replace.
2. With a marker, mark the edge where the motor meets the base (the edge farthest away from the pump). 3. Remove the belt guard bolt and nut. 4. Remove the front belt guard cover. 5. Loosen the four motor mounting bolts. 6. The belt tension will pull the motor toward the pump. Remove the belt from the unit and set it on the ground. 7. Using the reference mark made in step 1, move the motor approximately 1/4" past the mark (moving it away from the pump). 8.
Troubleshooting ! WARNING: For your own safety do not try and run the air compressor while troubleshooting. TROUBLE Compressor will not run PROBABLE CAUSE 1. Unit is plugged into extension cord 2. No electrical power 3. Blown fuse 4. Breaker open 5. Thermal overload open 6. Pressure switch bad Motor hums but cannot run or runs slowly Fuses blow/circuit breaker trips repeatedly REMEDY 1. Remove extension cord 2. Verify unit is plugged in. Check fuse/breaker or motor overload 3. Replace blown fuse 4.
TROUBLE Thermal overload protector cuts out repeatedly PROBABLE CAUSE 1. Low voltage 2. Clogged air filter 3. Lack of proper ventilation/room temperature too high 4. Unit is plugged into extension cord Air tank pressure drops when compressor shuts off 1. Loose connections (fittings, tubing, etc.) 2. Tank drain valve open 3. Check valve leaking REMEDY 1. Check with voltmeter 2. Clean filter (see Maintenance section) 3. Move compressor to well ventilated area 4. Remove extension cord 1.
Troubleshooting (continued) TROUBLE Low discharge pressure PROBABLE CAUSE 1. Air leaks 2. Leaking valves REMEDY 1. Listen for escaping air. Apply soap solution to all fittings and connections. Bubbles will appear at points of leakage. Tighten or replace leaking fittings or connections 2. Remove head and inspect for valve breakage, weak valves, scored valve seats, etc. Replace defective parts and reassemble ! 3. Restricted air intake 4. Slipping belts 5. Blown gaskets 6.
TROUBLE Excessive belt wear PROBABLE CAUSE 1. Pulley out of alignment 2. Belt too loose or too tight 3. Belt slipping 4. Pulley wobbles Oil in the discharge air 1. Worn piston rings 2. Compressor air intake restricted REMEDY 1. Realign motor pulley with compressor pulley 2. Adjust tension (See Drive Belt Section) 3. Adjust tension or replace belt (See Drive Belt Section) 4. Check for worn crankshaft, keyway or pulley bore resulting from running the compressor or motor with loose pulleys.
