When in the Start/Stop Option, the pressure switch stops the motor when the air tank pressure reaches the factor set "cut-out" pressure. For safety purposes, this switch also has a pressure release valve located on the side of the switch designed to automatically release compressed air from the air compressor pump head and its discharge line when the air compressor reaches "cut-out" pressure or is shut off. This allows the motor to restart freely. Moving the switch to the "Off" position will remove power from the pressure switch and stop the air compressor. MOTOR THERMAL OVERLOAD: The electric motor has a manual thermal overload protector. If the motor overheats for any reason, the thermal overload will cut off power, thus preventing the motor from being damaged. Wait until the motor is cool before pressing the thermal overload button to reset and begin working again. AIR INTAKE FILTER: This filter is designed to clean air coming into the pump. To ensure the pump continually receives a clean, cool, dry air supply this filter must always be clean and ventilation opening free from obstructions. Replace filter when necessary. AIR COMPRESSOR PUMP: To compress air, the pistons move up and down in the cylinders. On the downstroke, air is drawn in through the air intake valves while the exhaust valves remain closed. On the upstroke, air is compressed, the intake valves close and compressed air is forced out through the exhaust valves, into the discharge line, through the pilot valve and into the air tank. PILOT VALVE: When the adjusting knob is turned completely clockwise to the fully closed position, the air compressor operates in the Start/Stop Option. When the adjusting knob is turned completely counterclockwise to the fully open position, the air compressor operates in the constant run position. SAFETY RELIEF VALVE: This valve is designed to prevent system failures by relieving pressure from the system when the compressed air reaches a predetermined level. The valve is preset by the manufacturer and must not be modified in any way. To verify the valve is working properly, pull on the ring. Air pressure should escape. When the ring is released, it will reseat. AIR TANK DRAIN VALVE: The drain valve is used to remove moisture from the air tank(s) after the air compressor is shut off. NEVER attempt to open the drain valve when more than 10 PSI of air pressure is in the air tank! To open the drain valve, turn the knob counterclockwise. AIR TANK PRESSURE GAUGE: The air tank pressure gauge indicates the reserve air pressure in the air tank (s). PRESSURE REGULATOR: The air pressure coming from the air tank is controlled by the regulator knob. Turn the pressure regulation knob clockwise to increase discharge pressure, and counterclockwise to decrease discharge pressure. OUTLET PRESSURE GAUGE: The outlet pressure gauge indicates the air pressure available at the outlet side of the regulator. This pressure is controlled by the regulator and is always less or equal to the air tank pressure. OIL SIGHT GLASS: The oil sight glass will register the amount of oil in the pump. The oil level should be at the center of the Oil Sight Glass. If low, add Senco® part number PC0344 compressor pump oil. PC2016 FEATURES REVIEW PREPARATION INITIAL SET-UP: 1. Read safety warnings before setting-up air compressor. 2. Ensure the oil level in the air compressor pump is adequate. The oil level should be at the center of the oil sight glass. If low, add Senco® part number PC0344 compressor pump oil. LOCATION: CAUTIONIn order to avoid damaging the air compressor, do not incline the air compressor transversely or longitudinally more than 10°. 1. Place air compressor at least 12 inches away from obstacles that may prevent proper ventilation. Do not place air compressor in an area: -where there is evidence of oil or gas leaks. -where flammable gas vapors or materials may be present. WARNING Serious injury or death may occur if electrical sparks from motor and pressure switch come in contact with flammable vapors, combustible dust, gases or other combustible materials. When using the air compressor for spray painting, place the air compressor as far away from the work area as possible, using extra air hoses instead of extension cords. -where air temperatures fall below 32°F or exceed 104°F. -where extremely dirty air or water could be drawn into the air compressor. ELECTRICAL: DANGERImproper connection of the equipment-grounding conductor can result in a risk of shock or electrocution. Check with a qualified electrician or service personnel if you are in doubt as to whether the outlet is properly grounded. Do not use any type of adapter with this product. If repair or replacement of the cord or plug is necessary, do not connect the grounding wire to either flat blade terminal. The wire with insulation having an outer surface that is green with or without yellow stripes is the grounding wire. WARNING This product must be grounded. If there should be...
