English FEATURES (Fig. 1) PILOT VALVE D55390, D55395, D55570, D55575, D55580, D55585 When the maximum air tank pressure is obtained, the pilot valve (H) will blow-off. This will cause the compressor to exhaust the air though the the pump head and not fill the tank. Pilot Valve with Manual Lock (D55170, D55180): The manual lock allows you to manually unload the compressor with air pressure in the air tank.
AIR INTAKE FILTER The filter (A) is designed to clean air entering the pump. To ensure the pump continually receives a clean, cool and dry air supply the filter must always be clean and the filter intake must be free from obstructions. 2. Turn knob clockwise to increase regulated pressure and counterclockwise to decrease regulated pressure. 3. When desired pressure is shown on the regulated pressure gauge push knob in to lock. I INSTALLATION Assembly (Fig.
English 230 Volt Conversion D55170, D55180 WARNING: Risk of electrical shock. Ensure motor is disconnected from the power source before rewiring motor leads. The motor supplied with this compressor is a dual voltage, 115 / 230 volts motor. It is wired for 115 volt but can be converted to 230 volt operation. Instructions for connecting the motor for operation at 230 volt can be found printed on the label attached to the side of the motor.
Voltage and Circuit Protection Refer to Voltage and Minimum Branch Circuit Requirements under Motor Specifications. CAUTION: Certain air compressors can be operated on a 15 amp circuit if the following conditions are met. • Voltage supply to circuit must comply with the National Electrical Code. • Circuit is not used to supply any other electrical needs. • Extension cords comply with specifications.
English Compatibility ELECTRICAL Refer to all safety instructions before using unit. Observe extension cord safety instructions if necessary. Always move the On/Off switch to the OFF position before removing the plug from the outlet. Air tools and accessories that are run off the compressor must be compatible with petroleum based products. If you suspect that a material is not compatible with petroleum products, an air line filter for removal of moisture and oil vapor in compressed air is required.
MOVING 1. Grasp handle (S) of compressor and lift compressor high enough so unit can be rolled on the front tire(s). WARNING: Risk of unsafe operation. Ensure proper footing and use caution when rolling compressor so that unit does not tip or cause loss of balance. 2. When location is reached slowly lower rear of compressor to ground. Always store compressor in a horizontal position. PREPARATION FOR USE Pre-Start Checklist (Fig. 1) Initial Set-up (Fig.
English 5. Move the On/Off switch to the ON position. The compressor will start. 6. Run the compressor for 20 minutes. 7. After 20 minutes, close the drain valve by turning clockwise so the air tank pressure can build. (D55170, D55180) NOTE: Rotate the manual lock on the pilot valve into the closed position. NOTE: After the compressor reaches blow-off pressure the unit will continue to run but will not build additional tank pressure until the air is used and the pilot valve reset pressure is reached.
CONSTANT RUN MODE 1. Ensure the On/Off switch (C) is in the OFF position. 2. Plug the power cord into the correct branch circuit receptacle. See Voltage and Circuit Protection under Installation. 3. Open the drain valve (counter-clockwise). 4. Move the On/Off switch to the ON position. The compressor will start. 5. Turn knob on top of pilot valve (H) fully counter-clockwise until fully open. 6. Close drain valve (clockwise). WARNING: Risk of property damage.
