The provided document is a multi-language user manual for DEWALT air compressors, specifically models DPC6MRC-QS, DPC6MRC-GB, DPC10RC-QS, DPC10QTC-QS, DPC10QTC-GB, DPC10QTC-LX, and DPC17PS-QS. This description will focus on the English section of the manual.
The DEWALT air compressor is a professional tool designed for the generation of compressed air. Its primary intended use is to power pneumatic nailing tools and tire inflators. Users must always ensure that the connected tool has a suitable air pressure value. The compressor is not suitable for use in wet conditions or in the presence of flammable liquids or gases. It is explicitly stated that the compressor is not permitted for use in the medical or food sector, nor for refilling oxygen tanks. The device is intended for intermittent operation, with duty cycles varying by model (e.g., S3-25 means 2.5 minutes ON, 7.5 minutes OFF for some models). Supervision is required when inexperienced operators use this tool, and children should never be left alone with the product.
Important Technical Specifications:
The manual provides a table with detailed specifications for each model, including:
- Tank Size: Ranging from 6 liters (DPC6MRC-GB) to 17 liters (DPC17PS-QS).
- Voltage: All models operate at 230V AC, except DPC10QTC-LX which is 110V.
- Power (Peak/Running): Varies from 1.5/1.1 HP/kW to 2.5/1.8 HP/kW.
- Current (A): Ranges from 5A to 13.5A.
- Pump Type: All listed models feature an "Oil-Free" pump.
- Noise Levels: Guaranteed sound power level (LWA) ranges from 89 dB(A) to 97 dB(A), with measured sound power levels (LWAm) from 87.4 dB to 95.5 dB. Noise uncertainty (KWA) is 1.5 dB, except for DPC17PS-QS which is 1.0 dB.
- Maximum Operating Pressure: All models have a maximum operating pressure of 8 bar / 116 psi.
- Maximum Tank Pressure: Varies from 8 bar / 116 psi to 13.8 bar / 200 psi, depending on the model.
- Air Displacement/Delivery: Air displacement (l/min / cfm) ranges from 170/6 to 292/10.2. Air delivery at 7 bar ranges from 75/1.7 to 130/4.6, and at 90 PSI from 81/2.9 to 141/4.9.
- Compressor Speed: Ranges from 1800 to 3750 RPM.
- Weight: Varies from 12.3 kg to 36 kg.
- Motor Protection Type: Most models feature "Automatic reset thermal protection," while DPC10QTC-LX and DPC17PS-QS have "Self-hold Thermal Protection."
- General Compressor Protection: All models are rated IP20.
- Duty Cycle: Varies by model, from S3 15% to S3 75%.
Usage Features:
The compressor is designed for ease of use with several key features:
- Automatic Operation: The compressor is fully automatic, controlled by a pressure switch that stops it when tank pressure reaches its maximum value and restarts it when it falls to a minimum value. The pressure difference between maximum and minimum values is typically about 2.4 bar (35 psi).
- Pressure Regulation: An adjustable pressure reducer (4) allows users to set the operating pressure to the desired value. The knob can be turned clockwise to increase pressure and anti-clockwise to reduce it. Some regulators may not have a "push to lock" feature, requiring only a turn of the knob.
- Safety Valve: Equipped with a factory pre-set safety valve (9) to prevent over-pressurization of the air tanks. Users are warned not to adjust or eliminate this device.
- Portability: Models like DPC17PS-QS feature handles (5A, 5B, 5C) and wheels for easier transport. Two people are recommended for lifting.
- Electrical Connection: Single-phase compressors are supplied with an electrical cable and a two-pole & earth plug, requiring connection to a grounded power socket. Extension cords must be three-wire, grounded, and of adequate gauge and length (refer to the provided table for guidance).
Maintenance Features:
Regular maintenance is crucial for the compressor's longevity and safe operation. The manual outlines a maintenance chart and specific procedures:
- Daily Maintenance:
- Check safety valve (9) functionality.
- Drain the air tank (2) to remove accumulated water. This is critical to prevent corrosion and potential tank rupture.
- Check for unusual noise/vibration.
- Check for air leaks by applying soapy water around joints and observing for bubbles while the compressor is pumping.
- Weekly Maintenance:
- Clean the compressor exterior.
- Motor Overload Protector: The motor is equipped with a thermal overload protector that shuts off the motor if it overheats. The unit must be unplugged and allowed to cool before restarting.
- Air Filter: The air filter should be fitted during installation.
- Pneumatic Connections: Always use pneumatic tubes with maximum pressure characteristics adequate for the compressor. Do not attempt to repair faulty tubes.
- Cleaning: The main housing and air vents should be blown clean with dry air regularly. Plastic parts should be cleaned with a soft cloth dampened with soapy water, avoiding solvents.
Safety Warnings:
The manual emphasizes numerous safety warnings, indicated by pictograms and signal words (DANGER, WARNING, CAUTION):
- Risk of Electric Shock: Disconnect from power supply before any work. Prevent body contact with grounded surfaces.
- Risk of High Temperatures: Some parts of the compressor can reach high temperatures; avoid touching them.
- Risk of Accidental Start-up: The compressor may start automatically after a power outage.
- Risk of Bursting: Improper tank drainage can lead to corrosion, rupture, or explosion. Do not drill, weld, or modify the air tank.
- Personal Protective Equipment: Always wear eye protection, and hearing and respiratory protection when required.
- General Safety: Never touch moving parts. Never operate without all guards in place. Store in a dry, locked place, out of reach of children. Keep work areas clean. Do not abuse the power cord. Do not operate when tired or under the influence of substances. Do not modify the compressor.
