This document is an operator's manual for the Masterforce 6 Gallon Air Compressor, model number 207-1508. It provides detailed information on the compressor's function, technical specifications, usage, and maintenance.
Function Description
The Masterforce 6 Gallon Air Compressor is designed to compress air and store it in a tank for various applications. It is ideal for a wide range of jobsite tasks, providing optimum pressure for air tools. The compressor features a 1.5 HP universal motor and an oil-free pump. The compressed air is discharged into the tank via a piston that moves up and down in the cylinder. A safety valve is included to prevent over-pressurization, automatically opening if the pressure reaches a preset level. The power switch allows manual control of the compressor's on/off state. An air pressure regulator adjusts the pressure delivered to the connected tools, while two gauges display the tank pressure and the regulated outlet pressure. The unit also includes quick couplers for easy attachment of air hoses and accessories, and a tank drain for removing moisture.

Usage Features
The manual emphasizes safety instructions, including work area safety, personal safety, and tool use and care. Users are advised to read and understand the operator's manual to reduce the risk of injury, electric shock, fire, and personal injury.
Work Area Safety:
- Keep the work area clean, well-lit, and free of flammable materials.
- Keep bystanders, children, and visitors away.
- Ensure the workshop is childproof with padlocks and master switches.
- Ensure ample lighting and no obstructions.
Personal Safety:
- Know the power tool, its applications, limitations, and potential hazards.
- Stay alert and use common sense; avoid operating while tired or under the influence of drugs or alcohol.
- Dress properly, avoiding loose clothing or jewelry, and keeping hair, clothing, and gloves away from moving parts.
- Avoid accidental starting by ensuring the switch is in the "OFF" position before plugging in.
- Remove adjusting keys or wrenches before turning the tool "ON".
- Maintain proper footing and balance.
- Always secure the work with clamps or a vise.
- Use safety equipment, including eye protection, dust mask, non-skid safety shoes, hard hat, and hearing protection.
- Avoid using on ladders or unstable supports.
Tool Use and Care Safety:
- Always use clamps or other practical ways to secure the workpiece.
- Do not force the tool; use the correct tool for the application.
- Do not use the tool if the switch does not turn it "ON" or "OFF".
- Disconnect the plug before making adjustments, changing accessories, or storing the tool.
- Never leave the tool running unattended.
- Store idle tools out of reach of children.
- Maintain tools with care, keeping cutting tools sharp and clean.
- Check for misalignment, binding, breakage, or other conditions affecting operation.
Electrical Safety:
- Avoid body contact with grounded surfaces.
- Do not expose power tools to rain or wet conditions.
- Do not abuse the cord; keep it away from heat, oil, sharp edges, and moving parts.
- Replace damaged cords immediately.
- Use proper extension cords (UL listed, "W-A" or "W" marked for outdoor use) of the correct gauge to prevent power loss and overheating.
Assembly and Setup:
- Unpack and inspect for damage.
- Position the compressor near an electrical outlet, at least 12" (31 cm) from any wall or obstruction, in a clean, well-ventilated area.
- Place the compressor on a hard, level surface.
- Connect the air hose to the universal coupler, applying plumber's tape to prevent air leakage.
- Before starting, pull the ring on the safety valve to ensure it operates freely.
- Set the power switch to OFF.
- Turn the air pressure regulator knob counter-clockwise until it stops.
- Attach hose and accessories.
- If the pump has been transported or turned upside down, allow it to sit upright for approximately 10 minutes before starting.
- Close the tank drain and plug in the power cord.
- Set the power switch to ON and allow the tank pressure to build until the motor stops at the cut-out pressure.
Shut Down Procedure:
- Set the power switch to OFF.
- Unplug the power cord.
- Reduce tank pressure through the outlet hose or by pulling and holding the safety valve ring open.
- Open the tank drain to ensure all moisture is drained, then close it.
Tool Compatibility:
The manual includes a chart detailing recommended tool usage for the 207-1508 compressor, indicating whether tools like inflation/recreation, nailers (finishing, framing, flooring, brad, roofing), die grinders, cut-off tools, paint sprayers, impact wrenches, drills, sanders, and grease/caulking guns are recommended for use, intermittent use, or not recommended. Users are advised to ensure appropriate air tool matching to avoid voiding the warranty.
Maintenance Features
Regular maintenance is crucial for the longevity and safe operation of the air compressor.
Daily Maintenance:
- Drain the tank: Condensation water accumulates in the tank and must be drained after each workday to prevent corrosion. Wear protective goggles. In cold weather, draining is especially important to prevent freezing.
- Check the safety valve: Pull/actuate the safety valve daily to ensure it operates properly and to clear any obstructions.
Monthly Maintenance:
- Test for leaks: Check all connections for tightness. Spray soapy water around suspected leak areas; if bubbles appear, repair or reseal the faulty component. Do not over-tighten connections.
Prior to Storing:
- Drain the tank: Follow the daily drainage procedure.
- Clean the compressor: Use an air blow gun to clean all dust and debris.
- Disconnect and wind up the power cord.
- Clean ventilation openings on the motor enclosure with a damp cloth.
- Release all pressure from the tank by pulling the pressure safety valve.
- Cover the entire unit to protect it from moisture and dust.
- Store in a clean, dry location. In cold weather, store the compressor in a warm building when not in use to prevent starting problems and freezing of condensation.
Troubleshooting:
The manual provides a comprehensive troubleshooting guide for common issues such as the motor not running or starting, the motor running continuously, low pressure, moisture in the discharge air, and compressor overheating. Solutions include checking power connections, replacing fuses, cleaning air filters, repairing leaks, and ensuring adequate ventilation.
The compressor is backed by a 90-DAY Money Back Guarantee and a 3-YEAR Limited Warranty. The warranty covers defects in material or workmanship under normal use but excludes expendable parts, commercial/rental use, and damage from abuse or misuse. For technical assistance or repair parts, a toll-free helpline is provided.
